Mesenchimal tumors of the scrotum are rare lesions. Here, we describe a case of symplastic leiomyoma of the scrotum, in a 49-year old man. This is the third case reported in the world literature. Grossly, the lesion is a white-gray nodule, with fasciculated pattern, on sectioning. Histologically, the neoplasm is formed by whorling bundles of fusiform cells, which have atypical nuclei, with occasional cytoplasmatic inclusions. Mitoses are absent. The muscolar nature of the lesion is demonstrated by positivity for Masson-trichrome stain and for actin and desmine antigens.
