BRAGA, Bruna Backsmann; MICHALANY, Alexandre Ozores; OLIVEIRA FILHO, Jayme de  and  CUCE, Luiz Carlos. Plasmoacanthoma. An. Bras. Dermatol. [online]. 2016, vol.91, n.5, suppl.1, pp.128-130. ISSN 0365-0596.

Plasmoacanthoma is an extremely rare verrucous tumor located on periorificial regions characterized by dense dermal plasmacytic infiltrates. Some authors classify it as a form of reactive plasma cell proliferation which represents a heterogeneous spectrum of mucocutaneous disorders. These plasma cell proliferations have been considered to be a benign immunologic inflammatory reaction to known or unknown stimuli. However, the etiology of plasmoacanthoma remains highly speculative. We report the case of a 40-year-old woman who presented with a lobulated warty lesion affecting the lower lip. Biopsy from the lesion was compatible with plasmoacanthoma, which remains an underreported disease in the dermatology literature.
