Surgery is the main treatment for acral melanoma (AM), involving wide local excision (removing the tumor and a margin of healthy skin), with margins based on tumor depth (Breslow thickness). Due to the complex anatomy of hands/feet, specialized reconstruction (flaps/grafts) or even partial amputation (finger/toe) may be needed, plus sentinel lymph node biopsy if spread is likely, while newer research suggests narrower margins might work, balancing cure with function.

Surgical Approach
Wide Local Excision (WLE): The primary goal is removing all cancer with clear margins, using guidelines like 0.5-1cm for in-situ, 1cm for <1mm deep, 1-2cm for 1-2mm deep, and 2cm for >2mm deep melanomas.
Depth Consideration: Deeper melanomas (thick) often need deeper excision to the fascia or fat
Reconstruction: Skin flaps or grafts are often required for larger defects on hands and feet, preserving function.
Margins & Function
Traditional vs. Newer Approaches: Historically, large margins (3-5 cm) were used, but studies suggest narrower margins (e.g., 1 cm) might be sufficient for acral lentiginous melanoma (ALM) without compromising survival, reducing functional loss.
Balancing Act: Surgeons balance achieving clear margins (oncologic outcome) with preserving function and quality of life (QoL) in these critical areas (palms, soles, digits).
Key Takeaway
Surgery is essential, but the extent (margins, reconstruction, amputation) is highly individualized, requiring careful planning by specialists to balance cancer clearance with preserving hand/foot function, with ongoing research exploring optimal margins.
