HS: hidradenitis suppurativa IL: interleukin INTRODUCTION Hidradenitis suppurativa (HS) is an inflammatory condition characterized by recurrent painful erythematous nodules developing most commonly in the axilla or groin. HS is a chronic condition culminating in scarring and often dermal sinus tracts. A microwave-based energy device (miraDry; Sientra, Santa Clarita, CA) is a noninvasive device approved by the US Food and Drug Administration for treatment of axillary hyperhidrosis. It uses microwave energy targeting apocrine and eccrine glands at the interface between the dermis and subcutis. We report a patient with inflammatory nodules and scarring mimicking HS developing after treatment of axillary hyperhidrosis using a microwave-based energy device.
