mucoepidermoid carcinoma of the pancreas is rare. here, a 63-year-old woman with left upper abdominal pain and abdominal distension is presented. her mucoepidermoid carcinoma was located at the left upper abdomen, arising from the pancreatic body and tail without invasion of pancreatic capsule. on pathologic examination, the tumor consisted of three types of cells, the majority being poorly dif...

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 distinct clinicopathological entity characterized histopathologically by components of both squamous cell carcinoma and adenocarcinoma [1]. This type of carcinoma is described in a variety of sites, including lung, pancreas, and uterine cervix, while the head and neck region is a relatively rare origin for this type of tumor [1]. The existence of adenosquamous ...

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...

We sought to determine if adenosquamous proliferation of early cellular radial sclerosing lesions of the breast harbours hot spot mutations and to help clarify its relationship to low-grade adenosquamous carcinoma as a potential form of early neoplasia. Four low-grade adenosquamous carcinomas, early radial sclerosing lesions from 13 individuals, and 4 benign proliferative breast lesions were mi...

Adenosquamous carcinoma is an aggressive and rare variant of squamous cell that has both glandular differentiation. We present a case occipital scalp adenosquamous in 43-year-old male who presented with mass was initially marble size, which progressively enlarges over years. There were no constitutional symptoms. No neurological deficit locoregional lymph nodes not palpable. Contrast enhanced c...

  Adenosquamous carcinomas of stomach are rare entities comprising 0.5% of stomach carcinomas. Here, we report a case of a 50-year-old female, who presented with weakness, pallor, and symptoms of gastric outlet obstruction. A partial gastrectomy was done and histology showed evidence of adenosquamous carcinoma of the antrum with metastasis to the perigastric lymph nodes. The patient condition ...

introduction : pulmonary adenosquamous carcinoma is an uncommon histological variety of bronchogenic carcinoma, and has histologic areas differentiated as both squamous cell carcinoma and adenocarcinoma and has clinical behavior more like that of adenocarcinoma. tumor stage is higher at the time of diagnosis, and survival is poorer. case presentation : we present a 65 years old woman with bulgi...

Formalin-fixed, paraffin-embedded tissues from 108 cases of invasive carcinoma of the uterine cervix, consisting of 40 cases of adenocarcinoma, 44 cases of adenosquamous carcinoma, and, as a control, 24 cases of squamous cell carcinoma were examined for the presence of human papillomavirus (HPV) DNA by in situ hybridization of high sensitivity using tritium-labeled HPV-2, HPV-6, HPV-16, and HPV...
