AimTo present clinical and laboratory characteristics of various forms of idiopatic lobular panniculitis (ILP) in modern rheumatology practice.Materials And MethodsThe study included 67 people (58 women and 9 men aged 20 to 76) with the referral diagnosis of "Erythema nodosa? Undifferentiated panniculitis?" in 76.2% of cases with a median disease duration of 78.91 [48; 540] months observed in the V.A. Nasonova Research Institute of Rheumatology. In 2007-2017 in addition to general clinical examination immunological, histological and immunohistochemical studies, computed tomography (CT) of the chest organs and tuberculin tests were performed.ResultsAnalysis of clinical manifestations allowed to distinguish four forms of ILP: nodular (n=30), plaque (n=10), infiltrative (n=15) and mesentric (n=12). The minimum median duration of the disease was detected in plaque form (8 [5; 11.5] months), while the median duration in case of infitrative form was 8.25 times longer (66 [36; 102] months, p38 °C and a small number (up to 5) of drain nodes; infiltrative - fever >38 °C, ulceration of nodes with the expiration of oily mass and scarring; mesenteric - pain in the abdominal area, the number of nodes less than 5 and the abdominal cavity CT results (inflammation of the adiopose tissue of the intestinal mesentery, omentum, adipose tissue of the pre - and retroperitoneal areas).ConclusionThe forms and activity of the disease determine the approaches to treatment in modern clinical practice. There is an obvious need to expand knowledge about this pathology among doctors and conduct further research in order to timely diagnose and search for the most effective methods of ILP treatment.
