Abstract
INTRODUCTION: The term lipomembranous panniculitis refers to a chronic inflammation of the subcutaneous cell tissue, probably representing a non-specific type of ischemic necrosis of the fatty tissue, common to several complaints. It is characterized by painful sclerotic subcutaneous deposits, located in the lower legs of obese, middle-aged woman, with a history of vascular insufficiency and stasis dermatitis. The condition may also appear in association with other inflammatory disorders. METHODS: This paper is a review of all cases of lipomembranous panniculitis diagnosed at the Skin Histopathology Laboratory at Santa Maria Hospital, Lisbon, from 1985-2005. In the histopathological study, the associated clinical processes were retrospectively analyzed and the risk factors/associated pathologies re-evaluated. RESULTS: Eight patients were identified, all women, and with an average age of 49. Over half the patients were overweight. In most cases the lesions had been evolving for over 6 months and were associated with chronic venous insufficiency of the legs, both from a clinical point of view (7 patients) and a histopathological point of view (6 patients). In two of the cases, the lesions occurred in patients with connective tissue disorders. CONCLUSION: Great variability was observed with regard to the clinical morphology of the lesions, the proposed diagnoses and prescribed treatments, all of which possibly highlight the non-specific nature of the process.
