title: Leg ulcer in Klinefelter's syndrome.
abstract: Hypostatic ulceration of the legs is relatively uncommon in men. Recently, the hypothesis that recurrent ulceration in men may be associated with chromosomal abnormalities such as Klinefelter's syndrome is gradually being accepted. Herein, we describe a patient with Klinefelter's syndrome complicated by recurrent leg ulcers, in whom immunological disorders such as positive antinuclear factor, antiphospholipid antibodies and cryoglobulins without venous insufficiencies were demonstrated. Interestingly, these abnormalities of immune functions were normalized after the androgen replacement therapy for Klinefelter's syndrome, and his leg ulcers immediately recovered.
