Patient's question:
Doctor, I have a considerate older sister. She told me today that her husband has several scattered, soybean-sized papules on one side of the scrotum, which are very itchy. The hospital conducted a thorough examination and said it was scrotal inflammation. She is very worried.Doctor's answer:
Erythematous type: Symmetrically arranged on both sides of the scrotum, with sharply defined red patches covered with thin gray or brownish crusts, with a rough surface. After peeling off the crust, slightly red skin is revealed, without significant infiltration. When the lesion spreads, it can fuse at the base of the penis.Papular type: Several scattered, peanut-sized papules have already appeared on one side of the scrotum, significantly elevated above the skin, flat-shaped, covered with thin brownish crusts. Over time, they continue to increase and spread, densely arranged symmetrically on both sides of the scrotal raphe, fusing into larger patches, and sometimes fusing at the base of the scrotum.
White papular psoriasiform type: This type is rare but very typical. It presents as a large area on the front of the scrotum, composed of fused, melon-seed-sized flat papules, with a silvery-white appearance. When scratched, silvery-white scales are shed.
