Incidental finding of paratesticular aggressive angiomyxoma in a 72-year-old monorchid male.

Aggressive angiomyxoma is an uncommon mesenchymal neoplasm. It arises from soft tissue of pelvis and perineum in fertile females, occurring very rarely in males. Its name emphasizes the common local recurrence and infiltrative tendency, but usually it does not metastasize. Currently, the first line of therapy is surgical excision, achieving R0 surgical margins, and radiological follow-up. This case report describes an uncommon, incidental finding of paratesticular aggressive angiomyxoma in an asymptomatic, cryptorchid 72-year-old male patient.
