Clinically Amyopathic Dermatomyositis Associated with a Metastatic Undifferentiated Carcinoma in an Adult Filipino Male: A Case Report

Abstract

A 40-year old Filipino male was managed as a case of clinically amyopathic dermatomyositis (CADM) after presenting only with pruritic photodistributed symmetric erythematous-violaceous patches, nail fold telangiectasia and the pathognomonic Gottron papules. There was no clinical evidence of muscle involvement. The patient shortly presented with a metastatic undifferentiated carcinoma on the cervical lymph nodes. This case demonstrates that dermatomyositis can present uncommonly as CADM with associated metastatic undifferentiated carcinoma.
