Idiopathic localized involutional lipoatrophy in a child with spontaneous resolution

Abstract

Idiopathic localized involutional lipoatrophy (ILIL) is focal loss of subcutaneous tissue without any clinical or histopathological inflammation. Histopathology of ILIL characteristically shows diminutive fat lobules composed of small adipocyte resembling embryonic fat tissue. Immunohistochemical examination reveals a number of CD-68 positive macrophages in the fat lobules. Most reported cases of ILIL were unilateral in young women; we are reporting a case of 4-year-old child with bilateral involvement showing quick spontaneous resolution.
