      Myofibroblasts are one of the most controversial cells in recent times. Ever since its first discovery, numerous discussions have been done on its illusive nature and functions. They are commonly considered as smooth muscle like fibroblasts. Their presence and distribution in normal and pathological conditions are still not clear since they are difficult to identify with the routine histological techniques. Recent studies have shown their ubiquitous presence in the body tissues hence suggesting their important role in both physiological functioning and pathological conditions. This review discusses briefly the cell in terms of its definition, possible precursors; mechanism involved in its modulation, most importantly how to differentiate it from its nearest counterparts such as fibroblasts and smooth muscle cells and finally its fundamental role in physiology and pathology.

      Popular use of Cordia ecalyculata extract is increasing due to its potential in inhibiting appetite. Its side effects on reproduction have not yet been reported. Thus, for the first time, this study investigated the potential reproductive toxicity of different doses of C. ecalyculata extract in adult male rats (n = 12/group), which received hydroethanolic extract of C. ecalyculata at 20, 100, or 400 mg/kg of body weight (b.w.) or distilled water (control group), orally (gavage) for 60 consecutive days. The testicular and epididymal tissue, sperm morphology, fertility, and pregnancy outcome were evaluated. The results showed that food consumption decreased significantly in the groups that received 20 or 400 mg/kg of extract, but b.w. was similar (P> 0.05) in all experimental groups. No significant alteration was observed in testicular weight. At the 400 mg/kg dose, the epididymal relative weight increased (P < 0.05), compared to the control group. There were several histopathological changes in testes and epididymis at all extract doses. In addition, the percentage of abnormal gametes increased (P < 0.05) and the gestation rate decreased (P < 0.05). In conclusion, the C. ecalyculata extract promotes reproductive toxicity in rats, but with no dose-dependent effect.

      Plasmablastic lymphoma (PBL) is an aggressive subtype of Non-Hodgkin Lymphoma (NHL) initially described in extra-nodal sites in an immunocompromised and later in immune-competent patients. PBL remains a diagnostic challenge due to morphological overlap with various other entities and also due to similarities on immunohistochemistry with plasma cell myeloma. In-spite of therapeutic advances, PBL remains an aggressive disease with high fatality rate. We describe 2 cases of this uncommon neoplasm; both in immunocompromised patients.

      Objective: The normal blood–brain barrier (BBB) is composed of tight junctions between endothelial cells and surrounding astrocyte foot processes. Breakdown of the physiological astrocyte-endothelial cell relationship occurs in adult metastatic and primary brain tumors. However, the astrocyte-endothelial cell relationship has not been studied in pediatric tumors. Materials and Methods: Utilizing specimens from cases of pilocytic astrocytoma (n = 5), medulloblastoma (n = 5), and low-grade diffuse astrocytoma (n = 1), immunofluorescence were performed using primary antibodies against CD31, glial fibrillary acidic protein (GFAP), and aquaporin 4 (AQ4). Clinical, magnetic resonance imaging, operative, and histopathological findings were analyzed. Results: Strongly-enhancing areas of medulloblastoma exhibited complete BBB breakdown with sparse GFAP and AQ4 staining around CD31-positive vessels. Moderately enhancing regions of pilocytic astrocytomas exhibited regions of intact BBB and vasculature surrounded by dense GFAP staining but reduced and disorganized AQ4 staining, suggesting tumor cells could not fulfill physiological BBB support. Non-enhancing low-grade diffuse astrocytoma demonstrated intact BBB with intense peri-microvasculature GFAP and AQ4 staining. AQ4 stained so strongly that AQ4 visualization alone delineated CD31-positive vessels. Conclusion: Taken together, BBB breakdown in pediatric tumors corresponds to a loss of normal endothelial cell-astrocyte foot process relationships. Further development of pharmaceutical agents capitalizing on this disrupted BBB is warranted in medulloblastoma and pilocytic astrocytoma. However, BBB integrity remains a challenge in treating low-grade diffuse astrocytoma before progression toward secondary glioblastoma.

      Pilomatrical carcinoma is a rare malignant hair follicle tumor. It may arise de novo or as a malignant transformation from benign pilomatricoma. The tumor is locally aggressive with an increased tendency of recurrence but with a low metastatic potential. A 51-year-old male patient presented with a slowly growing mass in the middle inner aspect of the left thigh. After surgical excision, microscopically the tumor was diagnosed as pilomatrical carcinoma.

      Background: Cadmium (Cd) is a toxic heavy metal of both environmental and occupational concerns. The health impact of ethno-botanical approaches in attempts to ameliorate its deleterious effects in biological systems should be an area of scientific interest since established therapies are often burdened with undesirable side effects. Aim: To determine the effects of polyphenol-rich extract of the leaf of Vernonia amygdalina (PEVA) on Cd-induced testicular toxicity, oxidative stress, and histopathology in Wistar rats. Materials and Methods: A total of twenty five (25) male Wistar rats were divided into five groups as follows: Group 1 (Control) received distilled water (0.2 ml/100 g i.p.) for 5 consecutive days and thereafter left untreated for 28 days. Group 2 received Cd alone at 5 mg/kg (i.p.) for 5 consecutive days. Group 3 was pre-treated with Cd as Group 2 and thereafter left untreated for a period of 28 days, whereas Groups 4 and 5 were pre-treated with Cd as Group 2 and thereafter received PEVA (orally) at two dose levels (200 and 400 mg/kg, respectively) for 28 days. Results: Cd administration induced reproductive toxicity as evidenced by lowered level of follicle stimulating hormone, luteinizing hormone, and testosterone (P < 0.05); perturbation of sperm characterization (P < 0.05); deleterious disruptions of the antioxidant system as evidenced by lowered levels of reduced glutathione and superoxide dismutase as well as elevation in thiobarbituric acid reactive substances level (P < 0.05); decrease in relative testicular weight (P < 0.05); and severe disseminated necrosis of the seminiferous tubules with terminally undifferentiated/necrotic cells as revealed by the histopathological examination. These conditions were sustained following administration of the two dose levels of PEVA. Conclusion: PEVA administration is not a suitable therapeutic choice for fertility enhancement in male Wistar rat model of Cd-induced decline in reproductive function.

      Idiopathic inflammatory myopathies (IIM) are a heterogeneous group of disease with complex clinical features. It has been sub-classified as: (1) Dermatomyositis, (2) Polymyositis, and (3) Inclusion body myositis (IBM). Nowadays, there are some studies in literature suggest necrotizing autoimmune myopathy and immune-mediated necrotizing myopathy should also be added to this group of disease. There is a debate in the diagnosis of IIMs and up until now, about 12 criteria systems have been proposed. Some of the criteria systems have been used widely such as Griggs et al.’s proposal for IBM. Clinical findings, autoantibodies, enzymes, electrophysiological, and muscle biopsy findings are diagnostic tools. Because of diseases’ complexity, none of the findings are diagnostic alone. In this study, we discussed the diagnostic criteria of IMMs and described detailed morphological features.

      Primary mesenchymal neoplasms of the adrenal gland are extremely rare. The most common primary sarcoma is adrenal angiosarcoma. We report the case of a 51-year-old patient who presented with left flank pain. After ultrasound investigations, the patient underwent surgical removal of an adrenal tumor. The gross adrenal specimen showed extensive cystic changes with old hemorrhage and necrosis. Histologically, irregular branching vascular channels were seen intermixed with solid areas of epithelioid cells. Immunohistochemical staining of tumor cells was positive with antibodies to cytokeratin and CD31. After a 12 months follow-up, the patient is still well with no sign of a relapse. Because of the epithelioid appearance and frequent expression of epithelial immunohistochemical markers, primary epithelioid angiosarcoma of the adrenal gland can be confounded with adrenal carcinomatous metastases. We report our findings with a brief literature review and discussion of differential diagnosis.

      Cytomegalovirus infection of the female genital tract is a rare entity. We present a case of 70 year old woman who came with recurrent pyometra, but was otherwise in good health. Hysterectomy was done and the endometrium showed occasional stromal cells with karyomegaly and intranuclear eosinophilic inclusions consistent with cytomegaloviral infection and dense lymphoplasmacytic infiltrate. This was an incidental finding in an otherwise immunocompetent nonpregnant woman, hence being reported for its rarity and uncommon presentation. Keywords: cytomegalovirus, inclusions, endometrium.

      Background: Identification of the cellular origin of astrocytic gliomas is a step for improving the treatment strategies. Tumor stem cells have been detected in different neoplasms and have a major role in tumor initiation, progression and therapy resistance. Objective: The study aimed to investigate the expression of nestin and survivin in different grades of astrocytic glioma as well as evaluation of their prognostic role in relation to other prognostic parameters. Methods: Immunohistochemical expressions of nestin and survivin were evaluated in 40 paraffin blocks of different grades of astrocytic glioma and correlated with other prognostic parameters. The obtained data were statistically analyzed. Results: The cases included 10 low grade, 12 anaplastic and 18 glioblastoma multiforme. There was a significant correlation between each of nestin and survivin with the histological grade of astrocytoma and tumor size (p < 0.001). Nestin was strongly correlated to survivin index (p < 0.001). The univariate analysis showed that high histological grade, high nestin score and high survivin index were significantly correlated with overall survival. Multivariate analysis for all investigated cases proved the independent prognostic significance of the nestin expression (p = 0.011). Conclusion: Nestin and survivin are adverse prognostic markers for astrocytic glioma that increase significantly with tumor progression and associated with poor overall survival. Therefore, nestin and survivin could be used to predict high risk group of astrocytoma with unfavorable outcome.

      We present a rare distinctive variant of invasive carcinoma of breast characterized by adnexal differentiation of tumor of trichoblastic type. The neoplasm was identified in a mastectomy specimen from an 83-year-old Chinese woman. Morphologically, the trichoblastic differentiation was characterized by the formation of solid sheets and nests of basaloid cells. The tumor cells were positive for cytokeratin 5/6, BER-EP4, bcl-2, and β-catenin. Stromal cells were positive for CD10. The tumor cells exhibited a “triple negative” profile; the nuclei did not react with antibodies to estrogen and progesterone receptors but failed to show overexpression of the HER2/neu protein. The MIB-1 labeling index averaged 20%. It is hoped that this case increases awareness for this unique morphological variant of invasive ductal carcinoma.

      Objective: C-kit functions as a tyrosine kinase receptor and represents a target for small molecule kinase inhibitors. The expression pattern for c-kit was studied in different human tumor types as gastrointestinal stromal tumor, malignant melanoma, breast and lung cancer, sarcoma and mastocytosis. C-kit expression in malignant tumors can be a factor that might affect the prognosis and its expression in different tumors was studied in respect of its correlation with the outcome. Imatinib or sunitinib therapy of KIT-positive tumors is an example of a targeted cancer therapy requiring immunohistochemical tumor analysis to identify patients that would benefit from this kind of therapy. This study is done on patients with breast cancer to find out the frequency of c-kit expression and to find out if it has any effect on the outcome of the patients and to compare the results with that of other ethnicities. Materials and Methods: Paraffin-embedded tumor tissues from 81 patients with breast invasive ductal carcinoma were analyzed immunohistochemically for c-kit expression and correlated to the survival of the patients after initial diagnosis using the follow-up data. Results: The mean age of the patients was 52.8 years. The median follow-up period was 22 months (range 1-37 months). C-kit immunopositivity was found in 37 cases (46%). Expression of c-kit was found in tumor samples with varying intensities and infrequently. Conclusion: There was no significant correlation between c-kit expression and prognosis.

      Background: The use of Carica papaya leaves for medicines and food in our rural areas is rampant, this is due to its availability and testimonies of its efficacy. Objective: This study was aimed at investigating the activities of C. papaya on the histo-architecture of some organs. Materials and Methods: About 20 Wistar rats were randomly divided into 4 groups of 5 each and received tap water, 2.5, 5, and 7.5 g/kg of ethanolic extract of C. papaya PO once a day for 14 days after which biochemical analyses was performed on the blood samples. The tissues were examined histologically. Results: Albumin was significantly increased (37.6 ± 2.70) in Group B (5 mg/kg) when compared with the control (32.4 ± 2.30). AST decreased significantly in all the treatment groups (68 ± 1.58, 87.4 ± 403, and 89 ± 1.58) when compared with the control (93.6 ± 1.14). ALT decreased in all groups but was significant in Group C (7.5 mg/kg) 22.8 ± 2.16 when compared with the control (30 ± 2.12). Urea decreased significantly in all the groups (3.34 ± 0.11, 3.78 ± 0.50, and 3.36 ± 0.28), creatinine decreased significantly in Group B (35.4 ± 2.79) when compared to their controls (4.52 ± 0.37 and 50.8 ± 6.37), respectively. Na+ and K+ significantly decreased in Groups C and B, respectively; there was no significant difference in other groups and electrolytes. There was increased level of both packed cell volume and hemoglobin significantly. Histologically, there were no tissue alterations in all the treatment groups. Conclusion: Complementary and alternative medicine is fast gaining popularity; this necessitates swift research on various dose ranges.

      Objective: The data available regarding the epithelial-mesenchymal transition (EMT) markers are little. This study aimed to evaluate the immunohistochemical expression of EMT markers; MYb-like, Swirm and Mpn domain-containing protein-1 (MYSM-1) and Twist-1 in renal cell carcinoma (RCC), in a trial to find their role in the prognosis of such type of cancer. Methods: Immunoexpressions of MYb-like, Swirm and Mpn domain-containing protein-1 (MYSM-1) and Twist-1 were assessed in tissue specimens of 50 patients with RCC, and correlated with other clinicopathological features. The findings and their correlations were statistically determined. Results: Low expression of MYSM-1 was negatively correlated with size of the tumor, primary tumor (pT) stage, Fuhrman grade (P < 0.001), age (P = 0.002), and lymph node metastases (P = 0.010). Immunoexpression of MYSM-1 was significantly correlated with distant metastases (P = 0.004), overall survival (OS) (P < 0.001), and local recurrence (P = 0.001). High expression of Twist-1 was positively correlated with pT stage, Fuhrman grade, lymph node, distant metastases, age (P < 0.001), clinical stage (P = 0.002), the presence of sarcomatous change (P = 0.004), and tumor size (P = 0.008). Immunoexpression of Twist-1 was significantly correlated with distant metastases (P = 0.009), OS (P < 0.001), and local recurrence (P = 0.003). Conclusion: Overexpression of Twist-1 is an indication of poor prognosis in patients with RCC, whereas that of MYSM-1 is a marker of good prognosis.

      A 47-year-old, single, Chinese woman presented with pain on the 1st day of menses for more than 30 years. Her dysmenorrhea worsened over years and underwent a total abdominal hysterectomy and bilateral salpingooophorectomy. The myometrium showed trabeculated appearance, and there were adhesions between ovaries and fallopian tubes. A pale solid brownish mass measuring 1.5 cm × 1 cm × 0.6 cm with fibrous whitish cut surfaces was present on the lateral wall of the uterus in the lower uterine segment. Histologically, adenomyosis and left ovarian endometriosis were confirmed. The lateral uterine wall nodule showed a tubular structure lined by ciliated pseudostratified columnar epithelium. Smooth muscle bundles were found around the entire tubular structure. Lobules of salivary type glands containing both serous and mucous cells are present. The pathological diagnosis of heterotopic respiratory mucosa (HRM) was made. To our knowledge, this is the first reported case of HRM of the uterine corpus.
