Acral melanomas contribute to approximately 2-3% of melanomas but are commonly misdiagnosed due to their rarity, subtlety at onset and tendency to display amelanotic features. This case report describes a 70-year-old male with an amelanotic melanoma misdiagnosed as a non-healing arterial ulcer. Histopathology demonstrated a Breslow 2.3 mm, Clark level IV acral lentiginous melanoma, which was definitively managed with surgical intervention. This case report highlights the importance of considering melanoma in the differential diagnosis of non-healing ulcers.
肢端黑色素瘤约占黑色素瘤的2%-3%，但由于其罕见性、发病初期的隐匿性以及呈现无黑色素特征的倾向，常被误诊。本病例报告描述了一名70岁男性，其无黑色素性黑色素瘤被误诊为不愈合的动脉溃疡。组织病理学显示为Breslow厚度2.3 mm、Clark分级IV级的肢端雀斑样黑色素瘤，通过手术干预得到了明确治疗。本病例报告强调了在不愈合溃疡的鉴别诊断中考虑黑色素瘤的重要性。
