Steatocystoma multiplex, also known as epidermal polycystic disease and sebocystomatosis,[1]:781 is a benign, autosomal dominant congenital condition resulting in multiple cysts on a person's body. Steatocystoma simplex is the solitary counterpart to steatocystoma multiplex.[2]

Causes and genetics[edit]

Steatocystoma multiplex has an autosomal dominant pattern of inheritance.

It is associated with defects in Keratin 17.[3] The condition is inherited in an autosomal dominant manner. This indicates that the defective gene responsible for a disorder is located on an autosome, and only one copy of the defective gene is sufficient to cause the disorder, when inherited from a parent who has the disorder.

However, a solitary case can also emerge in a family with no prior history of the disorder due to the occurrence of a mutation (often referred to as a sporadic or spontaneous mutation).[citation needed]



The cysts can be removed via excision, though conventional cyst excision techniques have proven impractical, and a specialized regimen is required.[4]
