“…Diversos autores apresentaram bons resultados terapêuticos e ausência de recidivas. Estudos demonstram que não foram observadas diferenças estatísticas na taxa de recorrência local dos melanomas subungueais in situ quando submetidos à cirurgia funcional comparado às amputações (ZHANG, et al, 2021).…”

“…The amputation of a digit at the MCPJ level reportedly resulted in 40% (thumb), 20% (index or middle finger), and 10% (ring or little finger) impairment of hand function, whereas loss at the DIPJ level led to only half of the functional impairment of that at the MCPJ level 76 . Therefore, non‐amputation functional surgery (FS) has become the standard of care for NMIS or shallow‐depth NM since sparing the phalanx during amputation preserves limb function and leads to improved cosmetic outcomes without decreasing survival rates 3,4,77–80 …”

Nail melanoma (NM) is an important differential diagnosis in patients with longitudinal melanonychia. However, diagnosis is often challenging as it is difficult to differentiate from other pigmented nail disorders. The main challenge for diagnosis is obtaining adequate nail matrix biopsy specimens for histopathological assessment. Furthermore, the histopathological changes in the early stages of NM are subtle and contribute to a delay in diagnosis and care. Therefore, the integration of clinical and histopathological analyses is essential. Clinical and dermoscopic features, such as a broadened width of asymmetric bands in an irregular pattern, with multicolour pigmentation, periungual pigmentation, and continuous growth, are features that support the diagnosis of NM. The essential histological features that must be assessed are cellular morphology, architectural features, melanocyte density, and inflammatory changes. The reported mutations in NMs were BRAF (0–43%), NRAS (0–31%), KIT (0–50%), NF1 (0–50%), and GNAQ (0–25%). Surgery is the primary treatment for NM. The recommended treatment for in situ or minimally invasive NM is functional surgery, but cases with suspected bone invasion should be treated with amputation. Targeted therapy and immunotherapy are indicated for advanced stages of NM. This review summarizes the updated guidelines for the diagnosis and treatment of NM.

“…The introduction of immune checkpoint inhibitors has changed the management of metastatic melanoma. However, lower response rates to immune checkpoint blockades have been observed in acral melanoma and nail unit melanoma, which may be due to smaller numbers of tumor-infiltrating lymphocytes, lower PD-L1 expression, and a lower mutational burden in acral melanoma compared with other subtypes of melanoma [ 71 ].…”

Acral melanocytic neoplasms, including acral melanocytic nevus and acral melanoma, are common melanocytic lesions in Asian populations. Both lesions occur on the volar surface of the hands and feet, and on nail units. Acral melanocytic nevi occur on the arch area of the sole, whereas acral melanomas frequently occur on weight-bearing areas of the sole, and on the fingernails. Therefore, the development of acral melanoma may be associated with chronic pressure, physical stress, or trauma. Dermoscopy is a useful adjunctive diagnostic tool for differential diagnosis. Acral melanocytic nevus is characterized by a parallel furrow pattern, whereas acral melanoma has a parallel ridge pattern. Genetic alterations are also different between the two types of lesion. BRAF and NRAS mutations are common in acral melanocytic nevus, whereas acral melanoma shows lower rates of KIT, NF1, BRAF, and NRAS mutations and remarkable copy number variations in genes such as CCND1, CDK4, hTERT, PAK1, and GAB2. Sentinel lymph node biopsy is important for staging and prognosis. Contemporary treatments for melanoma include targeted therapy for mutations and immunotherapy, such as anti-PD1 inhibitors.
