Synonym: melanoameloblastoma, pigmented ameloblastoma, pigmented epulis, progonoma of jaw, retinal anlage tumour. (05 Mar 2000) |
| pigmented dermatofibrosarcoma protuberans | An uncommon variant of dermatofibrosarcoma protuberans containing heavily pigmented dendritic melanocytes scattered between spindle cells of the tumour. Synonym: Bednar tumour, storiform neurofibroma. (05 Mar 2000) |
| pigmented epulis | A benign neoplasm of neuroectodermal origin that most often involves the anterior maxilla of infants in the first year of life. It presents clinically as a rapidly growing blue-black lesion producing a destructive radiolucency; histologically, it is characterised by small round undifferentiated tumour cells interspersed with larger polyhedral melanin-producing cells arranged in an alveolar configuration. Synonym: melanoameloblastoma, pigmented ameloblastoma, pigmented epulis, progonoma of jaw, retinal anlage tumour. (05 Mar 2000) |
