Question 1 of 1
1. Question
Week (612): Case 1
A 37 year old man underwent an orchiectomy for a palpable mass.
Correct
Answer: Smooth muscle hyperplasia of testicular adnexa
Histology: Surrounding the vas deferens, cord vessels, and adjacent to the testis is a bland hypocellular proliferation of fibrous tissue.
Discussion: This condition is benign and of unknown etiology. It consists of fascicles of smooth muscle surrounding the vas and vessels of the distal spermatic cord, with interstitial growth between the structures of the spermatic cord. It lacks the circumscribed growth of a leiomyoma. A paratesticular fibrous pseudotumor is more fibrous and related to the tunica as opposed to the distal cord. The importance of recognizing the lesion as a specific entity is to correlate the histological findings with the clinical presence of a mass lesion, justifying the surgery.
