Two Cases With Benign Cephalic Histiocytosis

Abstract

Benign cephalic histiocytosis is a rare form of non-Langerhans cell histiocytosis in infants and children characterized by a self-healing eruption of papules and macules on the head and neck. Its etiology is unknown. Due to its rarity we report these two cases of benign cephalic histiocytosis. The first case was a 1.5 year-old boy with small, asymptomatic, yellow-brown papules distributed over his trunk and upper extremities and yellow-brown plaques localised bilaterally to his cheeks. The second case was a 16 months old boy with purple-erythematous papules and nodules on his left cheek, left earlobe and right preauricular region ranging from 2 mm to 5 mm in diameter. There were no symptoms or signs of systemic involvement in both of the cases. It is uncommon and can therefore be easily mistaken for other more common skin diseases seen in children.
