Melanoma of the lentigo maligna subtype presents diagnostic and treatment challenges because of ill-defined clinical margins in cosmetically and functionally sensitive areas of the head and neck with extensive sun damage. This review highlights the natural history, varied clinical presentations, and pitfalls in histologic diagnosis. The focus is on the surgical management, comparing excision and pathologic tissue processing techniques of wide excision, Mohs micrographic surgery, and staged excision. Staged excision is recommended for optimal surgical margin control. Nonsurgical treatment modalities are also reviewed for the elderly or unresectable cases.

Teledermoscopy (TDS) emerges as an efficient tool for diagnosing skin lesions. In Sweden, double reading is the standard of care, but risk factors for misdiagnosis or mismanagement using single reader evaluations (SRE) are not well-studied. This study aimed to assess the accuracy of SRE compared with the gold standard in TDS.

Background: Lentigo maligna (LM) and lentigo maligna melanoma (LMM) are the most prevalent subtypes of melanoma, primarily affecting sun-exposed areas of the face in individuals aged 65 to 80 years. LM accounts for approximately 80 % of in situ melanomas and carries a risk of progression to LMM, which constitutes 4 % to 15 % of global cutaneous melanoma cases. This report discusses the clinical challenges and management strategies for recurrent LM, with an emphasis on accurate diagnosis and surgical intervention.

Metastatic melanoma with unusual histopathology can be diagnostically challenging. One exceptionally rare cutaneous manifestation of metastases is blue-nevus-like metastatic melanoma (BNLMM). A 74-year-old male presented with a blue-gray lesion on his left helix in the same anatomical region of a previously resected lentigo maligna.

Background: Desmoplastic melanoma (DM) is a rare subtype, accounting for less than 5% of primary cutaneous invasive melanomas. DM often arises in chronically sun-exposed skin, in older individuals. While the incidence of cutaneous melanoma has increased globally, trends specific to DM are less documented and studies on survival outcomes for DM are inconsistent.
