Description
The Medium Biopsy is a microscopic evaluation of a tissue sample ranging from 0.6 to 2.4 cm in size. This is commonly used for excisional skin biopsies, the removal of moderate-sized polyps, or lymph node biopsies to check for disease or abnormalities.
Medium biopsies often involve the complete removal of a small lesion or a significant portion of a suspicious area. The pathologist slices the tissue into ultra-thin sections, stains them, and examines the cellular structure to differentiate between benign (harmless) growths, infections, inflammatory conditions, and malignancies (cancer).
Clinical Significance:
-
Dermatology & General Surgery: Frequently used to diagnose skin cancers (like melanoma or basal cell carcinoma) after a lesion is excised.
-
Lymph Node Analysis: Helps determine if an enlarged lymph node is due to infection, lymphoma, or cancer spreading from another site.
Sample Requirements:
-
Specimen: Tissue piece (0.6 – 2.4 cm).
-
Container: Standard specimen jar pre-filled with 10% Neutral Buffered Formalin.
-
Preparation: Usually obtained via a minor surgical procedure under local anesthesia.
