A controlled cohort study examining the onset of hypertension in black patients with keloids.

We compared the incidence of hypertension in 281 black patients with keloids and 148 black patients with tinea versicolor (control). No difference in the overall incidence of hypertension was detected, however, we detected an increased incidence of hypertension in patients with keloids under thirty (7.9%) as compared to the control (0%).
