Diffuse lower limb lipoatrophy.
Lipoatrophic panniculitis is the term used to describe those panniculitides in which atrophy of the subcutaneous fat is the main residual lesion. They can be classified as primary or secondary. Primary lipoatrophic panniculitis is idiopathic, whereas secondary lipoatrophic panniculitides include those because of infection, malignancy, pancreatic disorders or connective tissue diseases. Usually, these entities are characterized by the appearance of tender, erythematous nodules or plaques that resolve leaving one or several localized areas with loss of subcutaneous fat. We report a 76-year-old female who developed diffuse and symmetric lipoatrophy of lower limbs after an extensive inflammatory process affecting both extremities from thighs to ankles. Histopathologic assessment revealed a lobular panniculitis with a lymphohistiocytic infiltrate, foamy macrophages and lipophagic granuloma formation. The most striking feature in our patient was the clinical presentation as a symmetrical diffuse inflammatory process resulting in lipoatrophy of the lower limbs.
