A 36-year-old woman presents with a pigmented lesion on the posterior aspect of her left calf as shown in the image). An excisional biopsy demonstrates a superficial spreading type of melanoma. Which of the following histologic features has the most important prognostic value in your evaluation of this patient?
|A.||Degree of melanocytic atypia|
Degree of vascularity
Depth of dermal invasion
Extent of intraepidermal invasion by melanoma cells
Correct answer :c
The condition described in question is melanoma.
Melanoma, also redundantly known as malignant melanoma, is a type of skin cancer that develops from the pigment-producing cells known as melanocytes.
Melanomas typically occur in the skin but may rarely occur in the mouth, intestines or eye
Although choices A, B, and D may be factors in melanoma aggressiveness, the evaluation of tumor thickness is recognized as the single strongest prognostic variable for melanoma.
