Abstract

A 26-year-old female presented recurrent painful, carbuncles at both axillae for 10 years. It caused offensive odor and scar. Tissue diagnosis was chronic hidradenitis suppurativa. She was treated using antibiotics followed by multiple excisions with drainage but showed no improvement. Isotretinoin provided no benefit. She was socially isolated and experienced lower quality of life. Consequently, she was sent for radiation therapy. Computed tomography simulation was performed revealing an ulcer with deep chronic pus tracts at her axilla. Three-dimensional conformal radiation therapy was provided with 6 MV photon (7.5 Gy in 3 fractions) covering all ulcers and pus tracts. On the last day of radiation therapy, carbuncles and wounds at the left axilla exhibited much improvement without pus. Three months follow-up showed much improvement of the lesions. The skin was smoother without pus or odor. Radiation therapy was confirmed one treatment option for chronic hidradenitis suppurativa.
