Membranous lipodystrophy, a hereditary disease, is characterized by symmetric multiple cystic bone lesions and progressive neuropsychiatric symptoms. In two patients, a 22-year-old woman and a 30-year-old man, as in others reported in the literature, neither the etiology nor the pathogenesis was apparent. Histologically, the lesions consisted of convoluted membranes interlaced with lipoid structures.
