ABSTRACT

Pityriasis lichenoides is a rare inflammatory dermatosis with no identified risk factors, which presents as flares with persistent papulosquamous lesions. Although the etiology is unknown, it is suggested that it may be a lymphoproliferative entity, associated with the presence of immune complexes or infectious processes. We report a 56-year-old male with a history of IgG mediated multiple myeloma and systemic lupus erythematosus, under treatment, who presented disseminated erythematous crusted lesions. No association with viral, bacterial or drug processes were found. A higher prevalence of this entity has been reported in male schoolchildren, the presentation during adulthood, with a neoplastic and autoimmune history is unusual.
