Pilonidal Sinus at The Appendectomy Incision

Abstract

Pilonidal sinus is a disease that progresses with inflammation due to hairs that penetrate the epidermis layer of the skin. This case report presented the diagnosis and treatment process of the incisional pilonidal sinus case, which occurred at an appendectomy incision. A 47-year-old male patient was admitted with purulent discharge and erythema for about three days in the appendectomy incision. The patient underwent appendectomy with a right paramedian incision approximately eight years ago, and recurrent abscesses developed in the incision scar in the postoperative period. The skin and subcutaneous tissues, including the abscess sac, were surgically excised. In the excision material taken from the patient, there was an intense inflammatory reaction with hair covering the entire dermis and erosion and ulceration of the epidermis.
