A 32-year-old Turkish man with a progressive appearance of indolent, skin-colored nodules on the trunk and proximal extremities is presented. Clinical and laboratory examinations did not reveal any other relevant abnormalities. Histological specimens showed focal, ill-defined depositions of acid mucopolysaccharides mainly in the reticular dermis. Collagen fibers were split up and separated. Ultrastructurally, activated fibroblasts and an increased synthesis of collagen fibrils and elastic microfibrils as well as numerous macrophages were noticed. Diagnostically, an unusual multiple type of cutaneous focal mucinosis is most likely.
