RESUMO
Adenosquamous carcinoma (ASC) of the stomach is a rare tumour. In this report we present a case of adenosquamous carcinoma in the antrum involving the duodenal bulb in a 84 year old woman. Although several theories about the possible origin of this kind of tumours had been proposed, histological and immunohistochemical findings agree with the possibility of a preexisting adenocarcinoma as the most reliable cause. The prognosis of ASC seems worse than that of adenocarcinoma because of the more extensive tumour depth and higher frequency of lymphatic and vascular permeation of the carcinomas cells when it is discovered.

An intra-abdominal desmoid tumour included in Gardner's syndrome is described. Some aspects of this unusual tumour are reviewed, emphasizing the value of CT to evaluate shape, location, size and relation with adjacent structures and therefore to decide the therapeutic plan, to avoid the need for exploratory laparotomies which are, moreover, so inadvisable in these patients. Although the, treatment of choice is surgery, it must be performed in accordance with CT findings. When surgery is not possible is incomplete or after recurrences, alternative methods are recommended.

We report a new case of retroperitoneal hibernoma. Hibernoma is a rare, benign soft tissue tumor whose constituent cells resemble those of brown fat tissue, which is present in human fetus and newborn infant and it gradually diminishes in quantity throughout adult life. Retroperitoneal location is unusual. Differential diagnosis with the liposarcoma (the most frequent tumour on this location) is based on the high vascularity of the hibernoma. Total resection of the tumour can achieve complete cure without recurrence nor metastasis.
