RESUMO
OBJECTIVES: To review the diagnosis and therapeutic management of scrotal wall smooth muscle tumors by reporting an illustrative case. To emphasize that despite their histological characteristics on presentation, compatible with malignancy, these tumors have a benign behaviour, even when their size is much bigger than the ones found in the review bibliography. METHODS: 75-year-old male who presented a big, very slowly growing, painless, mobile, hard, not adhered to deep layers, non transilluminating scrotal tumor. RESULTS: Pathology reported a giant bizarre scrotal leiomyoma. CONCLUSIONS: We emphasize the atypical characteristics of this case, which despite its compliance with almost all classical criteria establishing the malignant character of tumor lesions has a benign behaviour. It complies with the criterion that, accordingly to reviewed bibliography, seems to be the most important to determine it: the absence of mitosis. We also insist on the importance of an adequate diagnostic approach which guarantees a proper surgical approach, for which we think ultrasound is essential.

Junto a las formas clasicas, el oligodendroglioma incluye formas inusuales con aumento de la actividad proliferativa, alteraciones vasculares, tumores mixtos (oligodendroastrocitoma) y tumores con celulas eosinófilas. El estudio con cultivo de tejidos nos ha permitido: a) confirmar el patron de crecimiento in vitro, b) la expresión de GFAP en todos los casos cultivados, c) el carácter primario de la transformación eosinófila citoplásmica. A la luz de este estudio, puede concluirse que: a) el patrón in vitro del oligodendroglioma es característico y permite identificar este tipo tumoral sea cual sea el subtipo, b) la expresión de GFAP es constante en todas las formas de oligodendroglioma, c) la tendencia a la maduración astrocítica parace ser una capacidad propia del oligodendrocito tumoral (AU)
