Necrotic Donor-Site Ulcer Due to Klebsiella Pneumoniae Infection Following Pubic Hair Follicular Unit Transfer in an Undiagnosed Diabetic: A Rare Case Report

This case report describes a rare complication of necrotic ulceration at a pubic hair donor site caused by Klebsiella pneumoniae in a 52-year-old man who was an undiagnosed diabetic. Six weeks post follicular unit transfer, the patient developed a painful swelling and a 3 × 5 cm necrotic ulcer in the inguinal region. Elevated blood glucose levels indicated undiagnosed diabetes. The infection was treated successfully with surgical debridement, enzymatic wound care, oral doxycycline, topical mupirocin, and antidiabetic therapy, leading to complete healing within 3 weeks without affecting graft survival. This case highlights the need for metabolic screening and culture-guided management to prevent donor-site complications.
