A Reversible Cause of Cutaneous Rash in a Patient With Alcohol Consumption.

ABSTRACT

The most common cutaneous manifestations of alcoholism include urticarial reaction, flushing, porphyria cutanea tarda, psoriasis, rosacea, seborrheic dermatitis, and pruritus. Here, we present a case of a young male with a history of alcohol abuse who presented with non-blanching, petechial, and perifollicular macular rash secondary to vitamin C deficiency in view of poor oral intake. The rash improved significantly with vitamin C supplementation. Although rare in developed countries, clinicians should keep vitamin C deficiency as a differential diagnosis for skin rash in alcohol consumers.
