Abstract:
Benign cephalic histiocytosis (BCH) is a rare non-Langerhans cell histiocytosis of unknown etiology. Clinically, lesions are characterized by small, red-to-yellow papules distributed mainly on the head, face, neck, and shoulders of infants and children. Histopathological specimens show massive histiocytic infiltration of the superficial dermis. Immunohistochemically, they are positive for CD68, but negative for CD1a and S-100. Two cases have been reported so far in the relevant work published in Korean literature. Herein, we report on an additional case of BCH.
