S100‐Negative Indeterminate Cell Histiocytosis in an African American Child Responsive to Narrowband Ultraviolet B
Abstract: Indeterminate cell histiocytosis is a rare cutaneous disease characterized by the presence of dendritic cells that lack Birbeck granules and immunophenotypically shares features of both Langerhans cells and macrophages. We describe a case of a 4‐year‐old
African American boy affected by a disseminated, exclusively mucocutaneous form of indeterminate cell histiocytosis. The eruption was successfully treated with narrowband ultraviolet B. The peculiar negativity of the Langerhans cell marker S100 is also discussed.
