Aseptic Subcutaneous Abscesses without an Underlying Disease / 대한피부과학회지

ABSTRACT

Aseptic subcutaneous abscesses are characterized by deep, round lesions histologically consisting of neutrophils, without evidence of microorganisms on culture. Although these are sometimes reported in healthy individuals, most are reported in patients with inflammatory bowel disease, including Crohn's disease and ulcerative colitis. A 79-year-old man without underlying disease presented with multiple skin-colored nodules and masses on his face and extremities 4 years ago. All of the microbiology studies for bacteria and fungi were negative and he did not respond to antibiotics. However, the lesions improved markedly after systemic prednisolone treatment. We diagnosed his lesions as aseptic subcutaneous abscesses. Further studies to evaluate inflammatory bowel disease were negative. Here, we report a case of multiple aseptic subcutaneous abscesses without an underlying disease.
