Acquired hypertrichosis lanuginosa. Rare manifestation of urinary bladder carcinoma

Hypertrichosis lanuginosa developed in a patient with carcinoma of the bladder. After regional lymph node metastases became evident, soft, fine, blond hair developed on his entire body, with the exception of the soles and the palms. Extensive endocrinologic evaluation demonstrated depressed testosterone levels and elevated levels of leutinizing hormone, changes not thought to be related to the hair growth. To our knowledge, this patient constitutes the second reported case of this rare syndrome in association with bladder carcinoma.
