Vaginal hyperpigmentation due to ochronosis.
BACKGROUND
Ochronosis is a manifestation of alkaptonuria, a rare metabolic disorder. It results in the accumulation of pigment in connective tissues. After several years, ochronosis may produce a distinctive form of degenerative arthritis.


METHODS
Vaginal ochronosis was diagnosed in an asymptomatic elderly woman with vaginal hyperpigmentation and severe degenerative arthritis.


CONCLUSIONS
Vaginal hyperpigmentation is a rare clinical finding that necessitates biopsy.
