title: Primary localized cutaneous nodular amyloidosis and CREST syndrome: a case report and review of the literature.
abstract: Primary localized cutaneous nodular amyloidosis (PLCNA) is a form of primary localized cutaneous amyloidosis (PLCA) that presents as yellowish waxy nodules on the extremities, face, trunk, or genitalia. We report the case of a patient with PLCNA and CREST (calcinosis, Raynaud phenomenon, esophageal motility disorders, sclerodactyly, and telangiectasia) syndrome. A diagnosis of her extensive PLCNA was made after biopsy specimens from the bilateral shins stained positive for amyloid extending from the superficial papillary dermis to the subcutis. Results of a workup were negative for paraproteinemia or signs of systemic amyloidosis and have remained so after 8 years of follow-up. We present a review of the literature describing the presentation and histopathology of the varying forms of amyloidosis.
