Digital mucous (or myxoid) cysts are harmless lesions that occur in middle-aged and elderly patients. While usually affecting the fingers, they occasionally occur on the toes. Digital cysts are prone to recur after simple excision, electrocoagulation, intralesional injection of adrenal corticosteroids, and a variety of other therapeutic maneuvers.
Excellent cure rates have been reported from wide surgical excisions; however, this substantial surgical procedure may cause impaired joint mobility. The multiple needling technique can be taught to and performed by the patient. Sterile disposable needles are the only equipment needed. Complications are nil. Multiple needling and expression of contents are usually required; only rarely does a single treatment eliminate the cyst. Multiple needlings appear to be the most satisfactory simple treatment for digital mucous cysts.
