RESUMO
Parathyroid hyperfunction condition has a very diverse and unspecific symptoms and signs. We have performed an anatomopathologic study of 146 parathyroid gland from patients diagnosed from hyperparathyroidism. About a 72.6% of the patients presented a parathyroid adenoma while in the rest 27.4% it was observed principal cells hyperplasia. Up to now we have not registered any cases of parathyroid carcinoma after anatomopathological exam of the removed gland. The mayority of the adenomas (85%) were found on the lower parathyroids and its size varied between 6 mm and 5 cm. In one case an double adenoma was diagnosed and in another two cases the adenoma was located in the superior mediastine.

Granular cell tumor, myoblastoma or Abrikossoff's tumor is an uncommon benign lesion, usually of slow-growing, that shows a predilection for the oral cavity, especially the tongue. Its real etiopathogenia remains still controversial and in it's histogenesis have been implicated several cell types. We report the case of a 18 years old woman with that diagnosis, confirmed in AP, who was operated by removal of the tumoration that was located in the left half-tongue. After 28 months she has not suffered any recurrences.

A case of malacoplakia associated with rectal adenocarcinoma is reported. Optical and electron microscopic study disclosed a histiocytic infiltrate adjacent to the adenocarcinoma containing spherical and concentric inclusions designated as Michaelis-Gutmann bodies. The pathogenesis is discussed and the literature is reviewed.
