Multiple myxoid cysts of both hands in a cashier--a case report.

We describe an unusual case of mucous cysts in 3 fingers of both hands in a 52-year old woman, working as a cashier. The cysts were localized over the joints, between distal interphalangeal joint and the proximal nail fold. It is possible that the job of the patient (i. e. counting money with both hands, repeated straightening and bending of distal phalanxes in the palms) could have influenced the development of numerous lesions. Radiological examination revealed no symptoms of osteopathic changes, only the growth of soft tissue, without any abnormalities in the bone structure. Contact tests showed no allergy to nickel. The cryotherapy and removing mucus form the DMCs caused complete recovery of our patient.
