We report on three Caucasian Greeks 2 males and 1 female (67, 54 and 62 years old) that were operated with sarcomatoid carcinoma of the lung, an uncommon tumor that sometimes is referred as pleomorphic carcinoma (spindle and giant cell carcinomas). These tumors are encountered in the thorax far more often than true sarcomas. There are many erroneous reports of pulmonary sarcomas made before the...

RATIONALE Sarcomatoid carcinoma is an extremely rare lesion in the common bile duct (CBD). PATIENT CONCERNS We present a case of sarcomatoid carcinoma of the distal CBD in a 51-year-old woman who presented with jaundice and abdominal pain. Whipple's operation was performed successfully. Microscopically, the tumor was a poorly differentiated carcinoma containing a component of sarcoma-like dif...

The author reports a rare case of sarcomatoid carcinoma with an emphasis on immunohistochemical features. A 79-year-old man was admitted to our hospital because of hematuria. An endoscopy revealed a large polypoid tumor in the bladder, and urine cytology demonstrated malignant cells. A cystectomy was performed. The patient is now alive without metastasis 4 months after the operation. Grossly, a...

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...

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...

The standard treatment for locally advanced urothelial bladder carcinoma is radical cystectomy or chemoradiation. Sarcomatoid urothelial carcinoma, a rare tumour, is treated with radical cystectomy because the response to radiation therapy alone is poor in other sarcomas. We report a case of high-grade hyperinvasive urothelial bladder carcinoma with sarcomatoid differentiation. The patient refu...

BACKGROUND Adrenocortical carcinoma is a rare cancer, with an incidence in the literature of 0.5 to 2 cases per million population per year. Adult adrenocortical carcinoma has a poor prognosis, underscoring the importance of identifying diagnostic and prognostic markers. METHODS We searched our laboratory database for all cases in the past 15 years with a diagnosis of adrenocortical carcinoma...

Although much has been characterized about squamous cell carcinoma of the lower female reproductive tract, there is limited knowledge and experience with cases demonstrating squamous cell carcinoma with sarcomatoid features. Sarcomatoid squamous cell carcinoma (SSCC) is mainly found in the upper aerodigestive tract with the larynx being the most common site in the head and neck region. (Otay et...

OBJECTIVES We report herein the clinical, histological, and immunohistochemical features of a case of sarcomatoid chromophobe renal cell carcinoma. METHODS/RESULTS A 59-year-old woman referred a two-month history of constant right flank pain, and hematuria. A right radical nephrectomy was performed. Gross pathologic examination showed a tumor located in the lower part of the kidney with two d...
