title: Nodular amyloidosis: clinical recognition of an unusual entity.
abstract: Nodular amyloidosis is a protein deposition disorder that is important to recognize in the clinical setting. Identification and differentiation from primary systemic amyloidosis, which has an identical cutaneous presentation, but serious systemic implications, is of particular significance. Our case report highlights two patients who presented with isolated involvement of the plantar surface and ungual phalanges, each with concomitant tinea pedis. Recognition and diagnosis of cutaneous amyloidosis enables discrimination from systemic disease, and if found, prompt institution of appropriate treatment.
