RESUMO
Adenomatoid tumor of adrenal gland is a very rare primary tumor with favourable prognosis. The mesothelial origin of this tumor was confirmed by multiple studies of various authors. This origin was proven by immunohistochemical and ultrastructural examinations. In our case report, we present an interesting case of the adenomatoid tumor of the right adrenal gland in a 55-year-old woman. Our case is the second well-documented case of this tumor occurring in a female adult patient. We emphasize the presence of an intraluminal thread-like bridging strands, generally considered to be a characteristic histologic feature of this tumor, which have not yet been reported in literature in adenomatoid tumor located in adrenal glands.

Malignant melanoma of soft parts (MMSP) is a rare tumor originally described by Enzinger in 1965 as clear cell sarcoma of tendons and aponeuroses because of its affinity to tenosynovial structures. Tumors are found predominantly at the extremities. First visceral case was described in 1993 in the duodenum. We describe the case of 64-years old man with malignant melanoma of soft parts in the stomach, in the pancreas, in the mesocolon, in the left thigh and in the left axilla. This patient was successfully treated surgically by the resection of the stomach, resection of the pancreatic head, extirpation of the tumor from mesocolon, from the left thigh and from the left axilla. In all these localisations the tumor was histologically and imunohistochemically proved to be MMSP (positivity: s-100 protein, vimentin, HMB-45 and negativity CK, EMA, desmin, actin). This multivisceral occurrence is extremely rare and according to the review of literature this is probably the first published case of MMSP in the stomach and in the pancreas.
