Delayed extensor tendon rupture: a complication of Mohs surgery.

A 63-year old man is presented who developed a ruptured extensor tendon of the hand 3 days following Mohs surgery (fresh tissue technique) for a recurrent squamous-cell carcinoma. Retrospective examination of this case led us to conclude that several different factors (partial tendon laceration, infection, and underlying medical problems) jointly contributed to this complication. These factors are discussed, along with recommendations for management of such cases.
