Granulomatous Periorificial Dermatitis in an Adult: A case report with review of literature.

Granulomatous periorificial dermatitis (GPD) is a benign, self-limiting eruption that is considered a clinical variant of periorificial dermatitis, also known as perioral dermatitis. It presents primarily in prepubertal children as monomorphic scaly papules over perioral, paranasal and periorbital areas of the face with rare occurrence in adults. We report a 36-year-old Omani male patient who presented to the Dermatology Clinic at Bahla Polyclinic, Bahla, Oman, in 2018 with a papular eruption over his face for the previous six months. Based on clinical and histopathological findings the patient was diagnosed with GPD with sarcoid-like histology. He was treated effectively with oral doxycycline and topical metronidazole. This report provides a review of the literature on GPD and summarises all reported cases in adults to date.
