A lupus erythematosus panniculitis lefolyásának jellegzetességei 17 betegünk retrospektív vizsgálata alapján

Abstract

Lupus erythematous panniculitis (LEP) is a rare type of chronic cutaneous lupus erythematous. Clinical characteristics are tender, subcutaneous nodules, erythematous plaques. Disfigurement of face and body might develop which affects the patient's quality of life. LEP can be the first sign of systemic lupus erythematous (SLE). Our aim was to review the clinicopathological characteristics and the course of LEP through our own patients. We retrospectively analyzed the clinical records of 17 LEP patients at Semmelweis University's Department of Dermatology, Venerology and Dermatooncology between 2000 and 2022. The male:female ratio was 1:16, average age was 37.8 years. Lesion localisations were proximal lower (8/17) and upper extremities (7/17), face (4/17), breast (3/17), chest (2/17), buttocks (2/17), back (1/17) and distal lower extremity (1/17). Lesion morphologies were nodules (11/17), plaques (7/17), lipoatrophy (4/17), ulceration (3/17), calcification (1/17). Discoid changes covered in 6 cases. In 10 cases, systemic symptoms were observed (arthritis (4/17), haematological (5/17), renal (2/17), anti-phospholipid syndrome (2/17). 7 patients fulfilled the EULAR/ACR criteria for SLE. Histology showed mixed type panniculitis in 8, lobular in 3 cases. Average time until diagnosis was 24.3 months. Among all our SLE patients, skin symptoms regressed following systemic immunosuppressive treatment. LEP patients with only skin manifestation were often resistant for the therapy of cutaneous lupus erythematous. The diagnosis of LEP often takes months or years. Wider knowledge of LEP would shorten the time to diagnosis, preventing disfigurement and possible damage of internal organs. Based on our observations, LEP without SLE might be treated with early immunosuppression. Orv Hetil. 2023; 164(5): 172-178.
