| benign juvenile melanoma | A benign, slightly pigmented or red superficial small skin tumour composed of spindle-shaped, epithelioid, and multinucleated cells that may appear atypical; most common in children, but also appearing in adults. Synonym: benign juvenile melanoma, epithelioid cell nevus, spindle cell nevus. (05 Mar 2000) |
| cancer, melanoma | A skin cancer that begins in cells called melanocytes that can grow together to form benign (not cancerous) moles. A change in size, shape, or colour of a mole can be a sign of melanoma. It can be cured if detected early, before spread (metastasis) to other areas. Diagnosis is confirmed by a biopsy of the abnormal skin. Sun exposure can cause skin damage that can lead to melanoma. (12 Dec 1998) |

| minimal deviation melanoma | <dermatology, tumour> A malignant melanoma showing less cytologic atypia than is usual in melanoma cells showing asymmetric expansile invasion of the dermis. (05 Mar 2000) |
| Cloudman melanoma | <tumour> A transplantable melanoma that arose spontaneously in a mouse of DBA strain, and which grows and metastasizes in mice of related strains. (05 Mar 2000) |
| halo melanoma | <tumour> A rare condition in which a melanoma is surrounded by an irregular area of depigmentation. (05 Mar 2000) |
| Harding-Passey melanoma | <tumour> A melanin-forming tumour that arose spontaneously in a non-inbred mouse, and that is transplantable to mice of many strains but does not ordinarily metastasize. (05 Mar 2000) |
