title: Erythroderma, hair loss, and sinus histiocytosis with massive lymphadenopathy in a XYY-male.
abstract: This paper presents a case of sinus histiocytosis with massive lymphadenopathy (SHML) presenting as erythroderma in an XYY-male aged 27. The patient had little or no scalp, axillary, or pubic hair. Histologically, lymph nodes indicated dilatation of the sinuses with proliferation of benign-appearing histiocytes possessing abundant clear cytoplasm, admixed with giant cells and pericapsular fibrosis. Infiltrating histiocytes in the lymph nodes were OKM-1 (CD11b) positive, which is characteristic of monocyte-granulocyte lineages. In the present case, the abnormal presence of erythroderma, hair loss, SHML, and a chromosomal abnormality, XYY, were thought to be incidental features.
