Fine-needle aspiration cytology of mammary myofibroblastoma: a report of six cases.

Objective: To evaluate cytologic features of mammary myofibroblastoma in order to establish the possibility of precise preoperative recognition.

Study Design: This was a multi-institutional study of 6 patients with myofibroblastoma (5 men and 1 woman) in which preoperatively fine-needle aspiration cytology was performed. Four cases showed classical histologic features, 1 corresponded to the cellular variant and the remaining 1 to the fibrous form.

[A neuroepidemiological study in Beira, Mozambigue].

Introduction And Objective: The application of epidemiology to the field of neurology is relatively recent although it has become so relevant that it is currently recognized as a new specialty: Neuroepidemiology. The objective of our study was to study the morbid-mortality of neurological disorders.

Patients And Methods: We made a retrospective investigation of all the patients admitted to the Hospital Central de Beira, Mozambique, between 1 January 1996 and 30 June 1999.

Hemangiopericytoma in a male breast. Report of a case with cytologic, histologic and immunochemical studies.

A hemangiopericytoma in a male breast was studied by fine needle aspiration (FNA) biopsy. The FNA smears contained tissue clumps showing knob-like formations of atypical cells, spindle-shaped cells and fragments of capillaries lined by normal endothelial cells. Immunocytochemical study showed a positive reaction for vimentin, but a negative reaction for desmin and keratin.

[Skin metastasis as the first manifestation of dissemination of bladder cancer].

Cutaneous metastases of vesical carcinoma are an uncommon finding and generally appear amid multisystemic dissemination. We present a case of appearance of multiple cutaneous metastases in the immediate postoperative period of a patient subjected to radical cystectomy, in which this affection was the only sign of metastatic seeding. We discuss the etiopathogeny and possible evolution of similar cases.
