Cutaneous focal mucinosis arising from the chin.

Cutaneous focal mucinosis is a type of degenerative-inflammatory dermal mucinoses characterized with asymptomatic, single, dermal mucin deposition. Because of its rarity, it is often mistaken clinically for other disorders such as sebaceous cyst, fibroma, myxoma, and xanthoma. In this study, we will discuss a case of cutaneous focal mucinosis arising from the chin of a 27-year-old man.
