Corymbiform nodular amyloidosis.

Amyloidosis is part of a group of deposition diseases. Nodular amyloidosis is a rare form of primary cutaneous amyloidosis. It affects men and women, usually over the age of 60 years. Presenting manifestation of the disease are yellowish-erythematous or brownish nodules or plaques in single or multiple infiltrates. Systemic evaluation should be performed to rule out involvement of other organs. Follow-up of the patient is important because the condition may progress to systemic amyloidosis. We report a case of nodular amyloidosis in which the lesion had a corymbiform aspect without systemic involvement and no recurrence after two years of follow-up.
