Which of the following is the most appropriate next step in management?? A: Surgical excision with 0.5-1 cm safety margins only, B: Surgical excision with 1-2 cm safety margins only, C: Surgical excision with 1-2 cm safety margins and sentinel lymph node study, D: Surgical excision with 0.5-1 cm safety margins and sentinel lymph node study, E: Surgical excision with 1 cm safety margins onlyn,  <response>: This is a question about the appropriate next step in managing a patient with a confirmed diagnosis of superficial spreading melanoma. The key details in the question stem are that the lesion is 1.1 mm thick, which puts it in the T1b category 0.76-1.0 mm thick based on the AJCC staging system. The choice of surgical margins and whether to perform sentinel lymph node biopsy depends on the tumor thickness. For melanomas between 1-2 mm thick, guidelines recommend wide excision with 1-2 cm margins and sentinel lymph node biopsy for staging.C: Surgical excision with 1-2 cm safety margins and sentinel lymph node study
