We report a case of acquired hypertrichosis lanuginosa associated with rectal cancer and discuss the cutaneous symptoms as a marker of malignancy. A 75-year-old man had noticed increasing growth of hair over his entire body 4 months before he was admitted to our hospital because of bloody stools. Advanced rectal cancer was diagnosed, and he underwent sigmoidocolostomy. ⋯ Levels of carcinoembryonic antigen and carbohydrate antigen 19-9 were slightly elevated. The patient died 5 months after the operation because of peritonitis carcinomatosa. We suggest that hypertrichosis lanuginosa is a marker of internal malignant tumors.
