Overview


Pityriasis lichenoides chronica is the mild, chronic form of pityriasis lichenoides, a skin disorder of unknown cause. This condition is characterized by the gradual development of symptomless, small, scaling papules that spontaneously flatten and regress over a period of weeks or months. Lesions at various stages may be present at any one time. Patients with this condition often have exacerbations and relapses of the condition, which can last for months or years.[1]
