Physicians dealing with diseases of the thorax have long been aware that carcinoma of the lung varies greatly in its clinical manifestations, and that certain types of bronchogenic carcinoma are much more amenable to surgical eradication than others. The great frequency with which bronchogenic carcinoma occurs and its apparent increasing incidence make it essential to determine as far as possib...

The 22 adenosquamous carcinoma cases were studied clinicopathologically. The tumor provides many difficulties such as: rapid spreading properties, delayed detection as advanced carcinoma because of the presence of endophytic growth, frequent prevalence of vessel permeation, and radioresistance. Adenosquamous carcinoma was categorized histochemically and histomorphologically into two types--aden...

Adenosquamous carcinoma is a rare tumor with coexisting elements of infiltrating squamous cell carcinoma and adenocarcinoma. This tumor is reported to arise in different organs but rarely in the oesophagus. In most cases, it shows highly aggressive biological behaviour with high propensity to regional lymph-node metastasis and poor prognosis. We describe the management of a patient with an aggr...

Adenosquamous carcinoma is a rare malignant tumor with poor prognosis that is characterized histopathologically by the simultaneous presence of distinct areas of adenocarcinoma and squamous cell carcinoma. Until 2004, only 59 cases of adenosquamous carcinoma have been documented in English literatures in the head and neck region since the first one being reported in 1968. The present report is ...

BACKGROUND Adenosquamous carcinoma of the ampulla of Vater is extremely rare, and its clinicopathological features are limited and described in few previous case reports. Here, we report curative resection of adenosquamous carcinoma of the ampulla of Vater at an early stage. CASE PRESENTATION An 81-year-old woman was referred to our hospital for investigation of the frequent elevation of hepa...

PURPOSE Bronchioloalveolar cell adenomas (BAAs) have been described in up to 10% of patients with bronchogenic carcinoma. Their prognostic significance is unknown. The purpose of this study was to determine the prognostic implications of finding BAAs coexisting in specimens resected for primary bronchogenic carcinoma and to determine how frequently BAAs can be detected radiologically. METHODS...

Objective: To analyze and compare clinico-pathologic characteristics and survival between lung tumors with mixed histologic pattern and our population of resected lung tumors with single histology in the same period. Methods: From January 1993 to December 1999, 1158 patients received resection for lung tumors. Of these, 59 (5.1%) presented a mixed histologic pattern on the surgical specimen. Th...

  Five hundred eighty patients underwent diagnostic flexible fiberoptic bronchoscopy: during June 1988 to March 1993 at the bronchoscopy center of Kerman university of medical sciences. Seventy six specimens were obtained from patients with bronchogenic carcinoma and 155 from patients with benign disease of the lung. The efficiency of brushing and washing techniques was compared with forceps b...

Adenosquamous carcinoma is an aggressive variant of squamous cell carcinoma. This report describes a case of adenosquamous carcinoma with clinical features of a benign lesion and discusses the differential diagnoses, especially regarding histopathological and immunohistochemical analyses. A 45-year-old male was referred to our outpatient clinic complaining about a rapid-growing enlargement in h...

BACKGROUND Adenosquamous carcinoma of the pancreas is rare. Our understanding of the disease and its prognosis comes mainly from small retrospective studies. METHODS Using the Surveillance, Epidemiology, and End Results (SEER) database (1988 to 2007), we identified patients with adenosquamous carcinoma (n = 415) or adenocarcinoma (n = 45,693) of the pancreas. The demographics, tumor character...
