One lump or two? Concomitant Leydig cell tumour and paratesticular leiomyoma in an adult man.

We present the first reported case of a concomitant Leydig cell tumour (LCT) and paratesticular leiomyoma in an adult man with a history of bilateral cryptorchidism. An 80-year-old man presented with a 2-month history of a left testicular lump associated with mild discomfort and a gradual increase in size on a background of bilateral cryptorchidism requiring multiple orchidopexy procedures as a child. Ultrasound confirmed a lesion suspicious for malignancy and he proceeded to a left radical orchidectomy. Histopathological assessment of the left testis revealed a concomitant testicular LCT with rare malignant features and paratesticular leiomyoma. 2014 BMJ Publishing Group Ltd.
