アナボリックステロイドのドーピングが原因と思われる爪の脱落を呈した1症例

抄録

I report a case of scalp hair loss and nail destruction as possible side effects of anabolic androgenic steroid (AAS) doping in a Japanese athlete. The patiet, a 27-year-old man, was an amateur bodybuilder who won the championship in a bodybuilding contest. However, he tested positive in a doping test for drostanolone and stanozolol, and was deprived of his championship.
In Japan, positive results in doping tests are very rare. The patient suffered from loss of scalp hair and destruction of the nails before the contest. In addition, he presented with hoarseness and soft tumors of the lower extremities. Laboratory data showed hypotestos-onemia caused by AAS doping. However, a hCG test revealed that he still had positive of sex function capacity. Therefore the patients natural course was observed without medical treatment, and the symptoms were resolved within four months after the contest. This is considered to be the first case of nail destruction caused by AAS doping reported in the world.
