Eccrine porocarcinoma (EPC) is a rare tumor. It develops from the intraepidermal ductal portion of the eccrine sweat gland. Metastatic disease is rare. We report a new case of metastatic eccrine porocarcinoma with a successful management and a good response to docetaxel. A 54-year-old man was admitted with a mass in the breast. Biopsy specimen found carcinomatous tumor proliferation with large anastomosing ducts. Cellular atypia were noted, with eosinophilic cytoplasm and round to oval nuclei. The tumor showed positive immunoreactivity for ACE and negative to anti-PS-100. Resection was performed. One year later, he presented with local and metastatic recurrences. The patient had received 3 cycles of cisplatin and 5-fluorouracil; he progressed with increase in mass size and number of lung lesions. He has been undergoing three cycles of docetaxel with complete response in the lung and regression of the breast mass. The mass was excised. Porocarcinoma is a very rare entity and poorly understood. In the metastatic phase, it has modest or no sensitivity to anticancer treatment. Docetaxel should be considered in the metastatic eccrine porocarcinoma.

Background. Although some mature cases of teratomas have recently been described in the cervix, they are not commonly found in the uterus, especially in immature forms. An immature uterine teratoma relapsing after surgery as malignant neuroepithelioma has never been reported in the literature. Case Presentation. We describe a case of immature teratoma which occurred primarily in the uterus in a 56-year-old female. Treatment consisted of total simple hysterectomy. Three months after surgery, the patient relapsed with voluminous pelvic mass and was treated with bleomycin, etoposide, and cisplatin-containing chemotherapy regimen. Conclusion. In this report and according to the pertinent literature, clinical and pathological features and management of uterine immature teratomas are discussed. The mainstay of treatment is surgery. The prognosis of this unusual disease remains uncertain.

Adenoid cystic carcinoma is malignant tumor that exceptionally occurs in the uterine cervix. It is mostly seen in postmenopausal women and has an aggressive clinical course. We report two cases of an adenoid cystic carcinoma associated with a high grade squamous intraepithelial lesion and invasive squamous cell carcinoma of the uterine cervix and discuss briefly its clinical and pathological characteristics.

ᅟAtypical teratoid/rhabdoid tumors are rare and highly malignant central nervous system tumors. They have no specific radiological features and often present several histological components that make a problem in differential diagnosis with medulloblastoma and primitive neuroectodermal tumors.We present the case of a newborn girl complained of a gradual proptosis of the left eye secondary to an expansive lesional process of the optic nerve. The location at the optic nerve, reported only twice in the literature, and an exclusive rhabdoid appearance on biopsy added additional differential diagnosis problems.The proptosis worsened and the infant died few days after two cycles of chemotherapy.Virtual slidesThe virtual slides for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/2037718783145212.
