A case of sinus histiocytosis with massive lymphadenopathy is reported. A 27-year-old male patient presented with papules and nodules on his scalp, neck and trunk for six months and enlargement of submandibular lymph nodes for three months. Histopathologic examination showed that in the dermis there were many pale-staining histiocytes with emperipolesis and in lymph node there were dilated sinuses filled with many histiocytes with emperipolesis. Immunohistochemical staining showed that these histiocytes were positive for S-100 protein and CD68 but negative for CDla. The patient was diagnosed as sinus histiocytosis with massive lymphadenopathy based on clinical data, histopathology and immunohistochemistry.
