Epithelioid angiomyolipoma is a rare mesenchymal tumor arising mainly in the kidney that can potentially behave aggressively. Epithelioid angiomyolipoma can often resemble sarcomatoid renal cell carcinoma, high grade renal carcinoma or sarcoma. Its similarity to renal cell carcinoma has been emphasized in most of the cases reported in literature. With the purpose of contributing to the awarenes...

Abstract Background Sarcomatoid carcinomas are extremely rare tumors made of epithelial and mesenchymal elements. They have been found in various organs, but presence the common bile duct (CBD) has only reported a handful times. Insight regarding clinical history, histopathology, treatment, prognosis is limited. The majority CBD sarcomatoid occurred elderly women, including this case. Surgical ...

BACKGROUND. Even if it is a rare variant growth pattern of squamous cell carcinoma, sarcomatoid carcinoma seems to have almost the same clinical manifestations and risk factors as conventional squamous cell carcinoma. CASE REPORT. This paper presents a complex case of a 59-year-old female patient known with laryngeal papillomatosis, who presented in our Department for moderate to severe inspira...

Sarcomatoid carcinoma of the pancreas is extremely rare. The current report presents a case of carcinosarcoma of the pancreas in a 48-year-old male. Pre-operative computed tomography scans revealed a large complex cystic and solid mass in the tail of the pancreas; the patient underwent a laparoscopic spleen-preserving left pancreatectomy. The tumor was shown to be made of cystic and solid compo...

Mucinous tubular and spindle cell carcinoma (MTSCC) is a recent entity introduced in the World Health Organization 2004 Classification. It is a tumour of low malignant potential. MTSCC is a subtype of renal cell carcinoma (RCC), which is characterized by a polymorphous histology, wherein the spindled epithelial cell is an inherent carcinomatous component. We report the case of a 57-year-old man...

OBJECTIVE According to several studies, when the histological subtype of renal cell carcinoma is established it is possible to attribute a different life expectancy to each patient. We analyzed the prognostic significance of the histological subtype in renal cell carcinoma. MATERIALS AND METHODS The authors retrospectively analyzed the follow-up of 230 patients after radical or conservative r...

A 66-year-old man initially underwent appendectomy and cytoreductive surgery for a low-grade appendiceal mucinous neoplasm with pseudomyxoma peritonei. One and a half years later, multiple disseminated lesions developed in rectus abdominis muscle and peritoneal cavity. Biopsy showed histopathological transformation to sarcomatoid carcinoma. This case illustrates that evolution of low-grade pseu...

CORRESPONDENCE An early lesion of pulmonary carcinosarcoma: possible diagnostic problem in frozen section interpretation Sarcomatoid carcinoma is a rare malignant neoplasm of the lung. 1 Its definition was ambiguous until the recent establishment of World Health Organisation (WHO) criteria, according to which it is classified into carcinosarcoma, pleomorphic carcinoma, and spindle cell carcinom...

A 78-years-old man presented with weight loss, dyspnea, cough and hemoptysis. He was an ex-smoker with a smoking history of 30 pack-years. Imaging studies revealed an endoluminal carinal mass and a tumoral mass arising from the posterior wall of the trachea was observed bronchoscopically. Endoscopic argon plasma coagulation was performed to take biopsies and to regain the airway passage. Recana...
