To investigate the correlation between peripheral blood CRP‐to‐lymphocyte ratio (CLR) and lactate dehydrogenase‐to‐albumin ratio (LAR) levels, prognosis, and the tumor microenvironment (TME) in patients with acral melanoma (AM), with a focus on tertiary lymphoid structures (TLS) and immune cell infiltration. This evidence concerns the gene ALB and acral lentiginous melanoma.
