Multiple pilosebaceous cysts
Redondo P, Vázquez-Doval J, Idoate M, Iglesias ME, Quintanilla E.
We report two patients initially diagnosed as having steatocystoma multiplex (SM). Other cysts showed characteristics of eruptive vellus hair cyst (EVHC). More than 30 and 14 cysts, respectively, were removed with histological hybrid characteristics of SM and EVHC.
This suggests that SM and EVCH are two closely related entities, which represent a naevoid malformation in the area where the sebaceous duct and hair follicle meet.
