Carcinosarcoma of the uterus is a rare tumor representing 2-4% of uterine malignancies. Its prognosis is poor with a 5 years survival rate of 10-30%. We report a first documented case of carcinosarcoma occurring in a 62 years old woman who presented with postmenopausal vaginal bleeding for one year. The preoperative biopsy of endometrium revealed a leiomyosarcoma. Total body Computerized Tomogr...

CONTEXT Carcinosarcoma of the pancreas is a rare entity comprising a small subset of all pancreatic neoplasms. Diagnosis is usually established by immunohistochemical examination of the resected specimen. Prognosis is limited to several months after resection. CASE REPORT We review the current literature on this rare type of neoplasia, considering histopathological and clinical features. The ...

Odontogenic carcinosarcoma is an extremely rare malignant odontogenic tumor with only a few reported cases. It is characterized by a true mixed tumor showing malignant cytology of both epithelial and mesenchymal components. It has been assumed to arise from pre-existing lesions such as ameloblastoma, ameloblastic fibroma, and ameloblastic fibrosarcoma. To date, the reported cases have exhibited...

Carcinosarcoma of the prostate is an uncommon malignancy with poor long-term prognosis. The cancer is typically discovered at an advanced stage, and with less than 100 reported cases, there is limited literature concerning treatment options. Our patient presented with a history of benign prostatic hypertrophy, erectile dysfunction, and nocturia. Biopsy of his prostate indicated that the patient...

Breast cancer is a heterogeneous type of cancer, and many different histology types exist. Carcinosarcoma of the breast is a rare entity and consists of two distinct cell lines comprising epithelial and mesenchymal components. It is usually larger in size than epithelial breast cancers and is characterized by a rapid increase in size. The majority are with high grade and triple negative recepto...

Carcinosarcoma of the uterus has been poorly characterized on cervicovaginal (Pap) smears, and we examine whether they effectively screen for carcinosarcoma and whether an abnormal Pap smear result has any clinical importance. Twenty-five patients with histologically confirmed carcinosarcoma had a conventional Pap smear shortly before diagnosis. Eleven smears (44%) originally were read as abnor...

OBJECTIVE Ovarian carcinosarcoma is a rare subtype of this disease that has not been thoroughly investigated. The aim of this study was to evaluate the prognostic factors and out comes in patients with ovarian carcinosarcoma. METHODS All patients with histologically confirmed ovarian carcinosarcoma who were treated at Cheil General Hospital and Women's Healthcare Center between January 2000 a...

Carcinosarcoma of the breast is an extremely rare and clinically aggressive tumor possessing carcinomatous components and malignant mesenchymal elements, with few cases reported in the literature. The prognosis of breast carcinosarcoma is poor when compared with more common types of breast cancer, such as ductal or lobular carcinoma. Furthermore, carcinosarcoma presents a diagnostic and therape...

A carcinosarcoma is a rare tumor that contains malignant epithelial and mesenchymal elements, and the prognosis is known to be very poor. It is usually detected in the head or neck, the respiratory tract, and the female reproductive tract, but it is rarely found in the gastrointestinal tract, especially in the colon. The histogenesis of a carcinosarcoma is still uncertain, though some literatur...

Carcinosarcoma is a rare neoplasm composed of malignant epithelial and stromal elements, and, for rats, carcinosarcomas in the kidney have not been reported. In a long-term study to gather background data, we encountered a spontaneous carcinosarcoma originating from the renal pelvis with metastasis to the lung. At necropsy, a mass was observed in the abdominal cavity, and white nodules were sca...
