Which procedure is used to sample skin tissue for diagnosis?

• A. X-ray
• B. Ultrasound
• C. MRI
• D. Biopsy

Answer: (D)

To diagnose skin conditions, doctors often need a tissue sample to study under a microscope. This is done with a biopsy, where a small piece of skin is removed and sent to a pathologist for histologic examination. The tissue details revealed by a biopsy—such as cell types, patterns of inflammation, infection, or cancer—provide definitive information that imaging alone can’t offer. Imaging methods like X-ray, ultrasound, and MRI visualize structures and processes noninvasively, but they don’t provide the cellular-level information needed to confirm many skin diagnoses. They’re useful for guiding assessment or identifying complications, yet they don’t replace the diagnostic clarity that a biopsy provides.
