SCLEROSING LYMPHOCYTIC LOBULITIS IN THE MALE BREAST

Sclerosing lymphocytic lobulitis is an inflammatory disorder of the br east that is well recognised in women. It has only been reported previ ously in two men; two further men with the condition are described her e. Both presented with a breast mass, and one was an insulin dependent diabetic. Biopsy specimens from both patients showed circumscribed pe rivascular and, to a lesser extent, periductal collections of B and T lymphocytes. Sclerosing lymphocytic lobulitis in the female breast sho ws predominantly perilobular inflammation. The predominantly perivascu lar distribution in men is consistent with the relative paucity of epi thelium in the male breast. Interlobular fibrosis with epithelioid fib roblasts was also present.
