Popis: Pityriasis lichenoides is a rare inflammatory skin condition presenting with diffuse red-brown papules with evolution polymorphism and mica-like crust on older skin lesions. We present a 60-year-old female patient with pityriasis lichenoides chronica that manifested ten days after streptococcal pharyngitis. Initially, palpable purpura appeared on the lower extremities and later, erythematous-squamous papules and plaques appeared at the site of the palpable purpura and on the upper limbs and trunk. The patient had no history of hematological malignancy, viral hepatitis, kidney involvement, systemic rheumatic disease, or ANCA-associated vasculitis. After administration of methylprednisolone 20 mg for one month and an antimalarial agent (hydroxychloroquine 200 mg, 1 tablet bid) for three months, the skin lesions subsided without recurrence.
