An atypical presentation of plasma cell gingivitis with generalized skin lesions.

This article aims to present a report of an atypical clinical presentation of a plasma cell gingivitis (PCG) case with unusual skin lesions. PCG is a rare benign inflammatory condition which can be classified into Type 4 hypersensitivity reaction. It occurs due to reaction to unknown antigen, often flavoring agents or spices found in chewing gums, toothpastes and lozenges. Histologically, the lesion shows dense plasma cells infiltrate in the connective tissue. Early diagnosis of PCG is essential to differentiate from variety of conditions, namely, leukemia, HIV infection, discoid lupus erythematosus, atrophic lichen planus, desquamative gingivitis, or cicatricial pemphigoid which must be differentiated through hematologic and serologic testing. In this article, we will discuss a case of PCG with unusual skin lesions.
