Solitary Plaque on the Chin

© 2018 Indian Dermatology Online Journal | Published by Wolters Kluwer Medknow A 56‐year‐old male patient presented with a solitary asymptomatic growth over the chin since 3 years [Figure 1]. There was history of trauma to the chin while shaving followed by development of a small raised lesion over the same site. There was history of gradual increase in size of the lesion over a period of 2 years. Dermatological examination showed a solitary well‐defined infiltrated skin‐colored plaque on the chin. The rest of the face was unaltered. The differential diagnosis included granuloma faciale, collagen nevus, and gnatophyma. Skin biopsy from the lesion on the chin showed sebaceous gland hyperplasia and peri‐appendageal lymphohistiocytic infiltration with fibrosis in the dermis [Figure 2a and b]. After confirming the diagnosis of gnatophyma, the patient was posted for surgical excision.
