5-month follow up, the patient reported a 30-pound weight loss and almost complete resolution of the hyperpigmented plaques and an overall improvement in her skin tone and texture.

CONCLUSION

Acanthosis nigricans, a skin condition more common in skin of color, is an ideal example of how lifestyle interventions can dramatically improve obesity related dermatologic diseases. As dermatologists, we need to acknowledge and embrace lifestyle interventions for the prevention and treatment of certain skin conditions. Although challenging, weight-loss needs to be addressed in obesity-related skin diseases including AN, intertrigo, hidradenitis suppurativa, and psoriasis, in addition to topical therapies. Additionally, this case highlights the importance of considering the diagnosis of AN for facial hyperpigmentation as it is often misdiagnosed and treated as melasma or another pigmentary disorder. Dermatologists need to recognize this common condition in obese patients and emphasize the importance of weight loss and healthy lifestyle changes as treatment options.
