Pityriasis lichenoides chronica.

Pityriasis lichenoides (PL) is defined as a skin disorder with an unclear etiology that mostly affects children and adolescents. Pityriasis lichenoides chronica (PLC) is the chronic form, characterized by recurrent collections of scaly erythematous papules that spontaneously disappear over weeks, months or years. Here we report a case of a male, who presented with the main complaint of partially brownish red nodules that were scaly and brown-black spots, without itching, all over the body, present over the past 2 years. The nodules extend to the stomach area, both arms, both legs and finally to almost all parts of the body. The patient was treated with 500 mg erythromycin tablets four times a day and 0.25% desoximethasone ointment which was applied twice a day. Pityriasis lichenoides chronica is a skin condition with unknown etiology that appears as scaly erythematous papules that are easily detached, recurrent and can disappear spontaneously for several weeks, months to years. A gold standard therapy for PL is not yet available and is still a future challenge. [ABSTRACT FROM AUTHOR]
