Post-inflammatory hyperchromia is an important sequel of inflammatory dermatoses. In addition to depigmenting topical treatments, chemical peels can be effective in treating it. The present report describes a case of post-inflammatory hyperchromia after treatment of Lichen Planus handled with thioglycolic acid peels. Thirty percent thioglycolic acid applied in the form of a peel is described as a therapeutic option with discrete results and can be considered an ally in managing this dermatologic condition.

INTRODUCTION: The relationship between cardiovascular disease, insulin resistance and vitiligo has been evaluated in studies. However, there is still no consensus on the subject.
OBJECTIVES: To evaluate the relationship between insulin resistance and vitiligo, in addition to the prevalence of risk factors for cardiovascular disease, in adults with vitiligo when compared to the control group.
METHODS: Cross-sectional study with a control group. A convenience sample of consecutive patients aged 14 years and over was used. Patients and controls were assessed with laboratory tests and anthropometric measurements. The LAP, HOMA-IR, and HOMAβ indices were calculated.
RESULTS: We included 130 patients, 73 with a diagnosis of vitiligo and 57 controls. There were no significant differences between groups when LAP, HOMA-IR, and HOMAβ were evaluated. Among the risk factors for cardiovascular disease, systolic blood pressure was significantly higher in patients with vitiligo.
CONCLUSIONS:There was no higher prevalence of insulin resistance among patients with vitiligo. Regarding the risk factors for cardiovascular diseases, only systolic blood pressure was higher in patients with vitiligo. Further studies are needed to elucidate the prevalence of insulin resistance and cardiovascular risk factors in patients with vitiligo.
