BACKGROUND Müllerian adenosarcoma (MA) is a rare neoplasm composed of benign epithelial and malignant stromal components. Its location in the cervix and the presence of heterologous elements are extremely infrequent (to our knowledge, only 14 more cases have been reported in the English literature). We describe another case of MA of the uterine cervix with(More)
Granulomas in bone marrow are an infrequent finding related to diverse disease. We reviewed 8057 bone marrow studies made over a period of 10.5 years, confirming the presence of granulomas in 40 patients. Global incidence was 0.50% and annual incidence 3.80 cases/yr. Because of the non-specificity of the morphological data, the diagnostic significance of(More)
Metastatic neoplasms of the breast are rare. Mammary metastases as the initial presentation are even more infrequent and can simulate a primary malignancy clinically and radiologically. Recognition of metastatic tumors in the breast is important because it would prevent unnecessary mutilating surgery and would lead to appropriate treatment of the primary(More)
Chemokines are implicated in tumor pathogenesis, although it is unclear whether they affect human cancer progression positively or negatively. We found that activation of the chemokine receptor CCR5 regulates p53 transcriptional activity in breast cancer cells through pertussis toxin-, JAK2-, and p38 mitogen-activated protein kinase-dependent mechanisms.(More)
Although spindle cell carcinoma (SC) is a common neoplasm in the oral cavity, upper respiratory tract, and other head and neck areas, its occurrence in the vulva is rare. We report a case of this rare condition with immunohistochemical, ultrastructural, and human papillomavirus (HPV) testing. The neoplastic cells were positive for vimentin, keratins(More)
The clinical, cytopathologic and histopathologic features of a case of gynecomastia induced by chemotherapeutic drugs are described. Fine needle aspiration (FNA) smears showed epithelial atypia, and an erroneous cytologic diagnosis of carcinoma was made. Histopathologic study showed gynecomastia with epitheliosis, papillomatosis and atypical ductal(More)
A case of primary malignant melanoma of the uterine cervix is presented. So far only 26 cases have been reported. Vaginal bleeding was the most common complaint. Total abdominal hysterectomy with bilateral salpingo-oophorectomy and adjuvant radiotherapy is the elective treatment. Prognosis for this entity is poor. The tumor seems to arise from melanocytes(More)
