What is the term for the surgical removal of a mole for diagnostic purposes?

• A. Incisional biopsy
• B. Excisional biopsy
• C. Shave biopsy
• D. Punch biopsy

Answer: (B)

The surgical removal of a mole for diagnostic purposes is referred to as an excisional biopsy. This procedure involves the complete removal of the mole, along with a margin of the surrounding healthy tissue. This technique is particularly useful for obtaining a clear view of the mole's characteristics as well as ensuring that any potential abnormal cells are entirely removed for accurate analysis.

Excisional biopsies allow for comprehensive examination by pathologists, which is essential in cases where there is suspicion of skin cancer or other skin conditions. By removing the entire mole and adjacent tissue, the likelihood of obtaining a complete and representative specimen for histological analysis is maximized.

The other types of biopsies, such as incisional, shave, and punch biopsies, serve different purposes or involve partial removal of tissue, which may not provide the same level of diagnostic accuracy or thoroughness as an excisional biopsy. For instance, an incisional biopsy involves taking a portion of the mole rather than the whole, which may miss surrounding abnormal tissue. In contrast, a shave biopsy only removes the upper layers of the skin and can leave deeper tissues intact, preventing a full assessment of potential malignancy. A punch biopsy, while providing a cylindrical sample of skin, similarly might not encompass the entire lesion. Therefore
