Jessner’s Lymphocytic Infiltration of the Skin in a 73-Year-Old Woman: A Case Report

Abstract:

Background: Case Report: Conclusions: Jessner’s lymphocytic infiltration of the skin (JLIS) is a rare and benign process of unknown cause. This disor-der affects both sexes, most commonly in the young adult population. However, the demographic characteristics remain largely unknown, due to limited information. JLIS clinical presentation is heterogeneous; lesions can be indurated papular or erythematous plaques on the upper body. Symptoms are variable, from asymp-tomatic to pruritus and burning sensation. A female patient aged 73 years presented with 10-day asymptomatic dermatosis on the left malar area after an insect sting. At the beginning, the lesion was clinically classified as an abscess and antibiotic therapy was prescribed with ciprofloxacin 500 mg every 12 hours for 5 days. However, due to the lack of clinical response, a biopsy was performed, which reported a predominantly lymphocytic nodular dermatitis. JLIS diagnosis was confirmed after laboratory and imaging tests. Intralesional infiltrations of triamcinolone (0.5 ml) twice within 15 days and mineral sunscreen 3 times a day were prescribed. After the treatment, the lesion had a complete resolution without recurrence to date. The present case reports JLIS in an older woman who presented a complete healing resolution of the lesion without recurrences after triamcinolone intralesional infiltrations and sunscreen protection.
