Describe hydrocystoma.

Hydrocystoma is a cystic affection of the sweat-gland ducts, seated upon the face. The lesions may be present in scant numbers or in more or less profusion. They have the appearance of boiled sago grains imbedded in the skin; the larger lesions may have a bluish color, especially about the periphery. It is not common, and is usually seen in washerwomen and laundresses, or those exposed to moist heat. In some cases it tends to disappear during the winter months. There are no subjective symptoms.

Treatment consists of puncturing the lesions and application of dusting-powder. Avoidance of the exciting cause (moist heat) is important.
