Cystic Formations (Obstructed Sweat Glands)

In some cases one sees developed in the skin a cyst, which takes its origin in a dilated follicle or sac of the perspiratory gland. The follicle of the sweat gland becomes obstructed, and instead of the gland inflaming and suppurating the fluid collects and distends the follicle. The line of demarcation between hydro-adenitis and cyst formation in the early stage is not well defined.

The continuous application of collodion is the best treatment; the cysts, however, may be punctured, and the contents allowed to escape; the incisions must, however, be deep enough.
