The clinical manifestation is generalized papular eruption mimicking lichen nitidus. The plain and enhanced MRI scanning of pituitary showed the disappear of high signal (at T1WI) of the posterior lobe of pituitary gland.

The immunohistochemistry showed histiocytes are positive for CD1a, S-100, CD68. The diagnosis of Langerhans cell histiocytosis was made. She was treated with systemic chemotherapy and the lesions resolved completely. Now she has been followed-up regularly.
