原发性肢端着色斑性黑色素瘤

定义

肢端雀斑样痣性黑素瘤是一种明显且罕见的黑色素瘤，影响手掌和足底皮肤或指甲部位。通常在这之前是缓慢进展的原位期，可能被忽略。它通常表现为手掌和脚底黄斑色素沉积的扩大区域，或表现为指甲板内的纵向色素带。更具侵袭性的肿瘤表现为溃疡性结节，当涉及到指甲时，可破坏甲板。在皮肤黝黑的人中，肢端雀斑样痣性黑素瘤占很大比例。

Acral lentiginous malignant melanoma is a distinct and uncommon form of melanoma affecting either palmar and plantar skin or the nail apparatus. It is usually preceded by a slowly progressive in situ phase which may be overlooked. It typically presents either as an enlarging area of macular pigmentation on the palms and soles or as a longitudinal pigmented band within the nail plate. More aggressive tumours present as ulcerated nodules which, when involving the nail apparatus, can destroy the nail plate. Acral lentiginous malignant melanoma accounts for a high proportion of melanomas seen in dark-skinned people.
