Intended diagnosis: Smooth muscle hyperplasia. Contributed by:MST
Code Diagnosis Comment Score
anonymous Smooth muscle hyperplasia of testicular adnexa (100%) nil  100
anonymous smooth muscle hyperplasia of testicular adnexa nil  100
anonymous Benign smooth muscle proliferation, consistent with hamartoma (smooth muscle hyperplasia) - 100%. nil  100
anonymous Smooth muscle hyperplasia (hamartoma) 100% nil  100
anonymous Smooth muscle hyperplasia 100% The less likely differential, leiomyoma, can be ruled out by more sampling showing absence of more solid interlacing fascicular growth pattern. Smooth muscle hyperplasia shows hamartomatous pattern of growth.  100
anonymous Smooth muscle hyperplasia Smooth muscle hyperplasia has been referred to "hamartoma" by some authors.  100
anonymous Left epididymal mass - Smooth muscle hyperplasia of testicular adnexa 100% Lesion not circumscribed enough to warrant labelling as leiomyoma  100
anonymous Smooth Muscle Hyperplasia of Testicular Adnexa, benign 100% nil  100
anonymous Leiomyoma 100% nil  90
anonymous Smooth muscle hyperplasia (Hamartoma) of epididymis. nil  100
anonymous Left EPIDIDYMIS mass, biopsy - HAMARTOMA. nil  90
anonymous Angiomyomatous proliferation Comment: suggest immunostaining to look for evidence of adenomatoid tumor  80
anonymous smooth muscle hyperplasia (80%), leiomyoma (20%) further sampling and correlate with gross appearance  100
anonymous SMOOTH MUSCLE HYPERPLASIA OF THE EPIDIDYMIS. (100% probability) nil  100
anonymous Smooth muscle hyperplasia of testicular adnexa (100%) nil  100
anonymous Hamartoma (90%), exclude PEComa group tumours (10%) Order HMB45.  80
