Perineal burn injury with hidradenitis suppurativa: A case report.

ABSTRACT

RATIONALE Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disease which usually presents with painful, deep-seated, inflamed lesions in the apocrine gland-bearing areas. Severe HS has interconnecting sinus tracts and when it occurs in the perianal region, perianal fistulas can form. Obesity and smoking are 2 risk factors for the development of HS. PATIENT CONCERNS We report a case of a 33-year-old male diagnosed with perianal HS and perianal fistula following a burn injury to the area that occurred during childhood. DIAGNOSIS Through integration of the clinical signs and imaging results, the patient was diagnosed with HS, Hurley stage III with perianal fistulas. INTERVENTIONS: The patient accepted surgical therapy. Performed under the general anesthesia, the procedure comprised sinus tracts excision and drainage. OUTCOMES: The patient was discharged from the hospital 6 weeks after surgery. LESSONS The pathogenesis of the HS in this case was the burn injury interfering with sweat gland formation around the anus. Moreover, the scar from the burn made surgical treatment difficult.
