Lymphomatoid Papulosis. Case in pediatric dermatological clinical practice

Abstract

A clinical case of lymphomatoid papulosis in a 10-year-old boy is described, clinically characterized by the presence of ulcerating nodes that resolve with the atrophy formation. The patient’s differential diagnostic workup included cutaneous anaplastic large cell lymphoma, cutaneous tuberculosis, polyarteritis nodosa, erythema nodosum, deep lupus erythematosus, and alpha-1 antitrypsin deficiency. Based on the history, clinical picture, as well as laboratory and instrumental studies, the patient was diagnosed with lymphomatoid papulosis. During the examination, no concomitant neoplastic diseases were identified in the patient. All elements resolved with the outcome being hyperpigmented spots and atrophy. To date, the relapse-free period of the disease in the patient is 10 months.
