Gastric carcinosarcoma is a rare cancer of adults with poor prognosis compared with other gastric malignancies. To the best of our knowledge, the present report is the first case of gastric carcinosarcoma with chondroblastic differentiation in Iran. A 63-year-old man with epigastric pain was admitted to the surgery department. Abdominopelvic CT-scan showed a hypodense mass lesion in distal gast...

Carcinosarcoma is a malignant tumor of biphasic character consisting epithelial and mesenchymal components. This rarely-seen has an exceedingly aggressive nature. While it rare in the urinary system, appears even more rarely renal pelvis. Thus, there are few publications literature on carcinosarcomas originating from paper presents 42-year-old male patient with carcinosarcoma pelvis (CSRP), kid...

Carcinosarcoma of the colon is rare. Seventeen cases have been reported in the English literature. Most cases occurred in the left side of the colon. Indeed, there is only one reported case of cecal carcinosarcoma. Carcinosarcoma has a tendency to distantly metastasize and shows dismal prognosis. We report a case of carcinosarcoma in the cecum and review the literature describing colonic carcin...

Carcinosarcoma is a rare biphasic malignancy consisting of intermixed epithelial and mesenchymal elements. Carcinosarcoma is particularly rare among children. We accepted a 7 year old patient with retroperitoneal carcinosarcoma. The tumor was totally resected and no recurrence is found 11 months after operation. Literatures has been reviewed and there are few reports of primary retroperitoneal ...

Carcinosarcoma is a highly malignant tumour exhibiting histological components of both carcinomatous and sarcomatoid elements. Carcinosarcoma is extremely rare in the sinonasal cavity. Due to the rarity and clinical diversity, these neoplasms are often misdiagnosed and pose a challenge in their management. Here we report a 44-year-old man with epistaxis and progressive symptoms of nasal obstru...

Carcinosarcoma of the salivary gland is an extremely rare tumor that is composed of both malignant epithelial and mesenchymal components. Diagnosing carcinosarcoma with fine-needle aspiration cytology is challenging because of its overlapping cytomorphologic characteristics with other high-grade malignant salivary gland tumors. Among the many features, including pleomorphic oncocytoid epithelia...

Carcinosarcoma is defined as a malignant neoplasm that is composed of both carcinomatous and sarcomatous components. The occurrence of carcinosarcoma in the bone is extremely rare. In this report, we describe the third documented de novo case of carcinosarcoma of the bone. A 59-year-old Japanese female presented with a painful tumor in her right lower leg.

Carcinosarcoma of the prostate is a rare neoplasm with malignant epithelial and mesenchymal components. Herein, we report the case of a patient who underwent multiple transurethral resections of the prostate showing adenocarcinoma initially then carcinosarcoma. He underwent a robotic-assisted laparoscopic cystoprostatectomy, bilateral pelvic lymph node dissection, and ileal conduit urinary dive...

BACKGROUND Esophageal carcinosarcoma is a very rare neoplasm and its clinicopathological characteristics and the prognostic factors that influence the clinical outcome of the patient remain a matter of controversy. PATIENTS AND METHODS Twenty patients with esophageal carcinosarcoma were referred to our institutions. Tissue blocks were reviewed and sections containing both carcinomatous and sa...

alivary gland carcinosarcoma is an exceedingly rare and ggressive neoplasm composed of a mixture of carcinomaous and sarcomatous components, with either component apable of metastasis. Salivary gland carcinosarcoma can rise in pleomorphic adenoma (PA) or de novo.1 The present study reports a case of the parotid gland de ovo carcinosarcoma, which contained salivary duct adenoarcinoma and sarcoma...
