apocrine hydrocystoma

Tuesday 16 June 2009

Definition: Benign apocrine hydrocystoma is a rare lesion, especially in the postauricular region, the commonest site being the lateral orbital rim.

It is a slow growing, asymptomatic transluscent swelling whose definitive diagnosis can only be made by histopathological study and the chemical analysis of the fluid.

Surgical excision in toto is the treatment of choice.
