Question

Which of the following methods is used when a section of the lesion, usually from the center, is removed for microscopic examination?

A) Excision biopsy.
B) Punch biopsy.
C) Shave biopsy.
D) All of the above.

Answer 1

When a section of the lesion, usually from the center, is removed for microscopic examination, the method used is typically a Punch biopsy (Option B).

Step-by-step explanation:

A punch biopsy is a method used to remove a section of a lesion, typically from the center, for microscopic examination to diagnose conditions such as skin cancer.

This process involves using a circular blade called a punch to remove a cylindrical piece of tissue for analysis.

The punch biopsy is particularly useful for diagnosing skin lesions and is often performed when conditions such as skin cancer are suspected.

An excision biopsy would involve the removal of the entire lesion, and a shave biopsy typically removes a sample from the surface of a lesion, rather than from its center.

Hence, the correct answer is Option B.
