Summary : Two patients presented with nodular lesions on their lower limbs. Histologically, the dermis, in one case, and the panniculus, in the other, displayed pseudocystic lesions delimited by a serpiginous membranous structure showing the staining characteristics of ceroid. One patient had sclerosing panniculitis while the other had a traumatic panniculitis.These cases illustrate that membranous fat necrosis is a non-specific histological finding and that multiple processes are involved in its etiopathogenesis.

Keywords : ceroid, lipodermatosclerosis, membranous fat necrosis, membranous lipodystrophy, sclerosing panniculitis, traumatic panniculitis.
