Steatocystoma multiplex and eruptive vellus hair cyst may be closely related conditions. Histological analysis of removed cysts revealed hybrid characteristics, suggesting a shared developmental origin.

Area of Science:

  • Dermatology
  • Histopathology
  • Genetics

Background:

  • Steatocystoma multiplex (SM) is a rare genetic disorder characterized by multiple cysts.
  • Eruptive vellus hair cyst (EVHC) presents as multiple small papules or cysts.

Observation:

  • Two patients initially diagnosed with SM presented with additional cysts exhibiting EVHC characteristics.
  • Surgical removal of over 30 and 14 cysts, respectively, revealed hybrid histological features.

Findings:

  • Histopathological examination demonstrated characteristics of both SM and EVHC in the excised cysts.
  • This suggests a potential overlap or close relationship between these two distinct cystic conditions.

Implications:

  • The findings indicate that SM and EVHC might represent variations of a single naevoid malformation.
