Primary nodular cutaneous amyloidosis--long-term follow-up and treatment

Abstract

A case of facial primary nodular cutaneous amyloidosis is reported. This illustrates: the striking appearance of this unusual condition; the investigations appropriate to establish the diagnosis and to exclude underlying systemic amyloidosis or a condition which might contribute to amyloidosis; and the difficulty of successful management. Initial investigation failed to reveal any evidence of systemic amyloidosis or an associated internal illness. Two amyloid nodules were excised, but 7 years later the patient developed further nodules on the adjacent facial skin and again sought dermatological advice. He was reinvestigated and again no underlying condition was found. A trial of cryotherapy was unsuccessful, but curettage and cautery produced a cosmetically acceptable result.
