We report our histologic and immunohistochemical findings in a rare case of cutaneous carcinosarcoma involving the helix of the ear. The tumor exhibited cellular features of both basal cell and squamous cell carcinoma and a malignant mesenchymal component that was consistent with malignant fibrous histiocytoma. The epithelial component exhibited a positive immunohistochemical reaction to cytoke...
The objective of this teaching case is to report the excellent results of using lattice radiation therapy (LTR) for the treatment of a large metastasis from ovarian carcinosarcoma. This new technical concept extrapolates the traditional spatially fractionated radiation therapy (GRID) technique to advanced three-dimensional (3D) high-dose radiation therapy using modern instrumentation in radiati...
Oesophageal carcinosarcoma is a rare type of oesophageal cancer composed of both squamous cells and sarcomatous cells. We report a case of a 71 year old man presenting with dysphagia and weight loss. Oesophagogastroduodenoscopy revealed a bulky mass with a preliminary diagnosis of only oesophageal carcinoma, and the oesophageal mass was resected with a transhiatal oesophagectomy. On surgical pa...
Carcinosarcomas, often referred to as malignant mixed tumors, are rare neoplasm. We reported herein a carcinosarcoma of the gallbladder in an elderly patient with long-term survival (4 years). The operation carried out was open cholecystectomy under the preoperative diagnosis of chronic cholecystitis and tumor of the gallbladder. Anticancer chemotherapy after cholecystectomy was performed by or...
We describe a case of carcinosarcoma of the lung in a 60-year-old female who was admitted with complaints of productive cough and an abnormal shadow in the chest X-ray. Sputum cytology showed both squamous cell carcinoma and adenocarcinoma cells. Malignant nonepithelial cells were identified in the needle biopsy specimen. Right middle and lower lobectomy was performed to reveal a carcinosarcoma...
The relevance of cell cycle regulatory markers with uterine carcinosarcoma was investigated. immunohistochemical expression p16, p53, and cyclin D1 were assessed using tissue microarray 55 eligible patients. p16 p53 showed a high rate strong (+3) immune reaction in carcinomatous/sarcomatous components (61.8%/70.9% 52.7%/56.4%, respectively). Cyclin 14.5%/7.3%of the components. Strong related to...
BACKGROUND Salivary gland carcinosarcoma is a rare and aggressive malignant mixed tumor in which carcinomatous and sarcomatous elements coexist and metastasize together. The tumor may occur in the background of a preexisting pleomorphic adenoma or may arise de novo. We report a case of a woman presenting with a carcinosarcoma de novo of the parotid gland. METHODS AND RESULTS Our patient under...
Carcinosarcoma is an uncommon mixed tumor of the lung. We present the case of a 65 year-old-male with cough and a right lower lobe radio-opacity who underwent resection, showing a large endobronchial tumor with an epithelial component of non-small cell carcinoma and malignant mesenchymal elements. The radiologic and histopathologic features are reviewed with reference to relevant literature.
Atypical teratoid rhabdoid tumor (ATRT) is a rare malignant tumor with gloom destiny. Our case was a 4-year-old boy with a temporal lobe tumor that was then became evident of ATRT with recurrent happening. In a retrospective review of all cytologic slides, we found unique rhabdoid cells that are morphologically evident cells for ATRT in both times. Unfortunately, the cells were overlooked at th...
