| basal cell nevus | A hereditary disease noted in infancy or adolescence, characterised by lesions of the eyelids, nose, cheeks, neck, and axillae, appearing as uneroded flesh-coloured papules, some becoming pedunculated, and histologically indistinguishable from basal cell epithelioma; also noted are punctate keratotic lesions of the palms and soles; the lesions usually remain benign, but in some cases ulceration and invasion occur and are evidence of malignant change; autosomal dominant inheritance.

| basal cell nevus syndrome | <syndrome> An inherited group of defects which involve abnormalities of the skin, eyes, nervous system, endocrine, glands and bones. The condition is characterised by an unusual facial appearance and a predisposition for skin cancer. (27 Sep 1997) |
| bathing trunk nevus | These large pigmented (often hairy) congenital nevi are important because of their increased risk (10 to 15%) of conversion into malignant melanoma. A biopsy can confirm if cells have turned malignant. Any change in a pre-existing nevus should prompt a physician evaluation. (27 Sep 1997) |
| Becker's nevus | A nevus first seen as an irregular pigmentation of the shoulders, upper chest, or scapular area, gradually enlarging irregularly and becoming thickened and hairy. Synonym: pigmented hair epidermal nevus. (05 Mar 2000) |
| blue nevus | A dark blue or blue-black nevus covered by smooth skin and formed by heavily pigmented spindle-shaped or dendritic melanocytes in the reticular dermis. Synonym: Jadassohn-Tieche nevus. (05 Mar 2000) |
| blue rubber bleb nevus syndrome | <radiology> Bean syndrome, sporadic (some autosomal dominant), rubbery, raised blue-black skin nevi (cavernous haemangiomata, 0.1 - 5 cm), GI mucosal haemangiomata, bowel: polypoid filling defects of varying sizes, visceral haemangiomata (by angio) associated with: leukaemia, medulloblastoma, hypernephroma, Mafucci syndrome More info: blue rubber bleb nevus syndrome (12 Dec 1998) |

| giant hairy nevus | <dermatology> These large pigmented (often hairy) congenital nevi are important because of their increased risk (10 to 15%) of conversion into malignant melanoma. A biopsy can confirm if cells have turned malignant. Any change in a pre-existing nevus should prompt a physician evaluation. (17 Dec 1997) |
| giant pigmented nevus | These large pigmented (often hairy) congenital nevi are important because of their increased risk (10 to 15%) of conversion into malignant melanoma. A biopsy can confirm if cells have turned malignant. Any change in a pre-existing nevus should prompt a physician evaluation. (27 Sep 1997) |
| cellular blue nevus | A large, acquired blue nevus in which melanocytes are often clear and large, alternating with pigmented spindle cells and which may expand deeply into the subcutis; malignant change is very rare. (05 Mar 2000) |
| pigmented hair epidermal nevus | A nevus first seen as an irregular pigmentation of the shoulders, upper chest, or scapular area, gradually enlarging irregularly and becoming thickened and hairy. Synonym: pigmented hair epidermal nevus. (05 Mar 2000) |
