Sumario: | Pyogenic granuloma is a common, benign, vascular growth that often appears as a rapidly growing mass on mucus membrane-lined surfaces such as the conjunctiva. Conjunctival pyogenic granulomas are common following trauma, burst chalazion or ill-fitting prosthesis. Also known as 'lobular capillary hemangiomas', these lesions typically appear bright red, fleshy and pedunculated. Treatment options include excision, topical steroid therapy and topical beta-blocker therapy. In this communication, the authors describe a rapidly enlarging, pedunculated black coloured conjunctival mass lesion in a 44-year-old woman, who had a recent history of chalazia. Given the location and the clinical appearance, a melanocytic tumour was suspected and the mass was excised. Histopathology and immunohistochemical studies confirmed the diagnosis to be consistent with that of a a necrotic pyogenic granuloma. Pigmented lesions of the conjunctiva, especially rapidly enlarging ones, need to be viewed with a high degree of suspicion to rule out malignant melanoma. Rarely though, benign lesions such as pyogenic granulomas that undergo necrosis may masquerade as conjunctival melanomas. |
