RESUMO
Cancer of the gall bladder is a rare malignant neoplasm with an unfavourable prognosis. Laparoscopic surgery has brought about the emergence of possible neoplastic diffusion along trocar tracts in cases where unrecognized carcinoma of the gall bladder is present. The authors present a case of neoplastic abdominal diffusion discovered 4 months after laparoscopic cholecystectomy in which histologic examination of the surgical specimen revealed the presence of unrecognized carcinoma of the gall bladder.

Biliary hamartomas are rare, benign malformations of the biliary tract, usually discovered at autopsy or erroneously confused with metastasis or other cystic hepatic lesions. For these reasons it is necessary to consider them in the differential diagnosis. The authors describe three cases of biliary hamartoma in which the definitive diagnosis was obtained only with the use of histologic examination which represents the only means available that can draw conclusions about the real nature of this lesion.

Papillary-cystic neoplasm of the pancreas is a rare neoplasm principally effecting women in the 2nd and 3rd decades of life. It is considered a low grade malignancy due to it's favourable prognosis and the rarity of metastatic diffusion. Pre-operative diagnosis is rare due to the similarity with other cystic pancreatic lesions. It is for this reason that definitive diagnosis is made at histologic examination of the surgical specimen and total surgical excision represents the therapy of choice. The authors herein describe 2 cases of papillary-cystic neoplasm of the pancreas, thus bringing the total number of cases reported in the world literature to 294.
