INTRODUCTION: We report an unusual @entity3202 involution of @entity6725 . CASE REPORT: A newborn @entity1 presented with 5 papular, nodular and @entity39 located on the upper part of the body. The diameter of the lesions ranged between 1 and 3 cm. Light microscopy showed an infiltrate with foamy and Touton cells. Langerhans' cell histiocytosis was eliminated because none of these cells showed reactivity for @entity2281 protein and @entity4896 . At the age of 8 years, all the lesions had spontaneously regressed leaving unusual @entity2318 that had the same size as the active lesions. DISCUSSION: We compared the clinical, histological and evolution data of our @entity1 with 251 published cases. The most significant clinical feature of @entity6725 is the spontaneous involution without any trace. However, @entity2117 , @entity42423 or @entity194 may occur. Atrophy is not frequent and can result from 2 mechanisms. Inflammation of the hypodermic tissue, which becomes @entity3202 and @entity194 that may also result from @entity1413 during the scarring process.
