Residents’ Corner: Multiple Pyogenic Granuloma-like Lesions Following Hair Transplantation

In 1985, Sarnoff et al. reported an unusual case of multiple pyogenic granuloma-like lesions occurring at punch graft sites following a hair transplantation procedure, a complication not previously documented in medical literature. A 36-year-old man developed these lesions after his third hair transplant session, where 40 grafts were transplanted. The lesions appeared as polypoid masses of granulation tissue at the recipient sites and were successfully treated with shave removal and silver nitrate cauterization. Histopathology confirmed the presence of highly vascularized connective tissue with a mixed inflammatory cell infiltrate. The patient showed no recurrence of the lesions one month later. The etiology and pathogenesis of these lesions remain unclear, but the case highlights the need for awareness of this potential complication among physicians performing hair transplantations.
