[Unusual pseudosarcoid granulomatosis of a prostatic adenoma]

In the reported observation, numerous granulomas of the sarcoid type in the absence of sarcoidosis were found under the capsule of the removed prostate adenoma in a man of 57 who was practically normal for 8 1/2 years after the operation. Some of these granulomas were formed around adenoma glands. Also, large periglandular lymphoidcell infiltrates were found, sometimes with foci of cells similar to epithelioid ones. It is assumed that these infiltrates may precede granuloma formation. In the same sections there were rounded foci of sclerotic changes which apparently may be due to scarring of granulomas. An infectious-allergic genesis of the disease is suggested.
