Adnexal smooth muscle hyperplasia resulting in non-traumatic testicular dislocation: A case report.

Tumors of the para-testicular adnexa are very rare and are typically histologically diagnosed as adenomatoid neoplasms, leiomyomata, or smooth muscle hyperplasia. Though these masses are usually benign, the potential for malignancy and mass effect causing intrascrotal discomfort necessitate proper diagnosis and excision. Herein, we describe a unique case of gradual, atraumatic testicular dislocation in a 40-year-old male caused by smooth muscle hyperplasia of the testicular adnexa affecting the epididymis and vas deferens. This case highlights the diagnostic and surgical challenges associated with this presentation.
