The treatment of choice is excision. However, when the cyst is acutely inflamed, incision and drainage is frequently the best approach. Following the resolution of the infection, the lesion is excised. The lesion nearly always is accompanied by a central communicating punctum, which is frequently obvious in the skin surface. They must be excised with an ellipse of skin in continuity. Other techniques of removal include punch biopsy aspiration followed by curettage and avulsion of the cyst wall.
