Abstract

Sebaceous hyperplasia (SH) is a proliferative abnormality of sebaceous glands, most often seen in elderly individuals. It consists of single or multiple, asymptomatic, small yellow papules with a central depression. The face is most commonly affected, but there have been reports of SH on the chest or genitalia. A lobular array of well-differentiated mature sebaceous lobules is noted on histological preparations. In this report, we describe a patient with SH on the penile shaft and parts of the scrotum.

Figure

• 

  Fig. 1 Numerous, 1~2 mm-sized yellowish papules scattered on the scrotum and proximal half of the penile shaft. Note the perifollicular distribution of the lesions.

• 

  Fig. 2 Histology shows a lobulated lesion composed of enlarged sebaceous glands (>4 around each pilosebaceous unit) extending down into the dermis. The cells are predominantly mature sebocytes with a peripheral germinative layer. No cytological atypia were present (H&E, ×100).
