Intrascrotal Dedifferentiated Leiomyosarcoma Originating from Dartos Muscle

A 46-year-old man, who had visited our hospital complaining of a small intrascrotal nodule ten years ago, returned to us because of the rapid growth of the nodule.

Computed tomography revealed a heterogeneously enhanced intrascrotal tumor of approximately 4×3 cm. The tumor and the right testis were excised with the adhered right scrotal skin. The pathological diagnosis was pleomorphic leiomyosarcoma with dedifferentiation originating from the dartos muscle. Urological dedifferentiated leiomyosarcomas are rarely reported and the clinical features are mostly unknown. This is the first report to describe the dedifferentiated leiomyosarcoma of the dartos muscle.http://dx.doi.org/10.1155/2014/841929
