INTRODUCTION Sarcomatoid carcinoma (SCA) of jejunum is an extremely rare condition. To our knowledge, only 17 cases have been reported in the literature. PRESENTATION We introduced an additional case of the sarcomatoid carcinoma of jejunum in a 62-year-old Chinese male who presented with epigastric pain for 3 weeks. Multiple tumors originated in the jejunum and metastases to mesentery lymph n...

Sarcomatoid carcinoma of the prostate is a rare variant of prostatic cancer, with less than 100 cases reported in the literature up to date. Tumors are most commonly composed of an admixture of both malignant glandular and spindle cell elements. The sarcomatoid component can vary from 5 to 99%. We report a case of a 76-year old Caucasian man who underwent transurethral resection of the prostate...

Sarcomatoid carcinoma of the urinary bladder is an uncommon neoplasm characterized histopathologically by the presence of malignant spindle cell and epithelial components. Albeit extremely rare, sarcomatoid carcinoma with small cell carcinoma has been reported. Herein, we describe an additional case of sarcomatoid carcinoma with small cell carcinoma and squamous cell carcinoma of the urinary bl...

he machine that is a cell is more than the sum of its protein parts. A large step toward understanding how those parts are so effectively put together has been taken by Patrick Aloy, Rob Russell (EMBL, Heidelberg, Germany), and colleagues. Their work has identified ‫ف‬ 100 yeast protein complexes and predicted interactions within and among many of them. " We were working on a large scale to mod...

Spindle cell proliferations of diverse types which vary greatly in their behavior may occur in the urinary bladder. Some of them such as the inflammatory pseudotumor and the postoperative spindle cell nodule are reactive and clinically benign although they may be responsible for significant symptoms. On the other hand, certain other lesions such as sarcomatoid carcinomas are typically highly ma...

Although small bowel intussusception is one of the most common abdominal emergencies in childhood, it is rare in adults and usually occurs as a result of an underlying pathology. Sarcomatoid carcinoma, a very rare subtype of lung cancer, rarely metastasizes to small bowel and causes complications. In this paper, we aim to describe a patient with small bowel intussusception caused by an isolated...

Sarcomatoid carcinoma is a very rare tumor. Though it has been more than a century since sarcomatoid carcinoma was first described by Wirchow, many unresolved points remain. Histogenesis and nomenclature are controversial. A proper management has not been defined. Patients suffering from this aggressive tumor have a very poor prognosis. However, in this paper a case with a disease-free survival...

BACKGROUND The sarcomatoid variant of metastatic renal cell carcinoma (RCC) has often an aggressive course and a poor prognosis, particularly when accompanied with brain metastasis. CASE REPORT We describe the case of a patient with sarcomatoid variant RCC in whom brain metastasis was observed as a new lesion during treatment with temsirolimus, despite other extracerebral metastatic lesions b...
