Acral lentiginous melanoma of the finger. Case report.

Abstract

Acral lentiginous melanoma (ALM) is a subtype of cutaneous

melanoma that primarily affects the palms, soles, and

subungual regions. We present the case of a 60-year-old male

with a history of smoking (with a non-significant pack-year

index), active alcohol use since youth, and type 2 diabetes

mellitus (diagnosed

6

years prior and treated with

glimepiride, metformin, and insulin glargine); his remaining

medical history was unremarkable. He presented with a

pigmented nail disorder that had been evolving for

approximately 10 months, prompting him to seek a

dermatology consultation. Upon specialist evaluation, a

suspected diagnosis of a malignant pigmented nail lesion was

established, and a biopsy protocol was initiated. In this

patient, the relatively early identification of the lesion

allowed for diagnosis at a localized stage, with favorable

histopathological characteristics and the prospect of

conservative management of the digit.
