• Two overweight male patients developed acanthosis nigrican of the axillae. Seven to nine months later, the patients developed hidradenitis suppurativa deep within the areas of acanthosis nigricans. On examination of biopsy specimens, the hyperkeratosis of acanthosis nigricans was found to extend into the follicles. In previous reports, Fox-Fordyce disease and pityriasis rubra pilaris have preceded the onset of hidradenitis suppurativa.
