Biopsy

Biopsy:
Collection of tissue specimen for histopathological investigation.

Indications:
• Suspected malignant changes
• Lesions that fail to heal, increase in size, bleed easily or ulcerate
• Tumours or growths not easily identified by inspection
• Inflammatory conditions where diagnosis is uncertain

Types of biopsy:
Shave – specimen is ‘shaved’
Punch – gives a cylinder of tissue from 2 to 8mm; convenient and quick to perform (but not used for small lesions)
Parallel incision – gives a ‘disc’ of tissue
Excisional – lesion is removed in ‘elliptical’ shape
