Biopsy and Brush Cytology of Oral Lesions

Removal of tissue from living beings for macroscopic examination, microscopic Analysis, bacterial analysis & combination of above are called “BIOPSY”.

Indications for Biopsy

  • Any lesion that persists for more than 2 weeks with no apparent cause
  • Any inflammatory lesion that does not respond to local treatment after 10-14 days (after removing local irritant)
  • Persistent hyperkeratotic changes in surface tissues
  • Any persistent tumescence, either visible or palpable beneath relatively normal tissue
  • Inflammatory changes of unknown cause that persist for long periods
  • Lesions that interfere with local function (e.g. fibroma)
  • Bone lesions not specifically identified by clinical and radiographic findings
  • Any lesion that has the characteristics of malignancy
  • Any tissue expelled from the body orifice
  • Research purpose and to know the progress of lesions.

Characteristics of Lesions that Raise Suspicion of Malignancy

  • Erythroplasia
  • Ulceration
  • Duration more than 2 weeks
  • Rapid growth rate
  • Bleeding lesion on manipulation
  • Induration Fixation

Oral Brush Cytology

  • Sensitivity > 96%”
  • Uses a special brush to collect epithelial cells
  • Brush is placed in contact with oral epithelium and rotated with firm pressure 5-10 times
  • Brush collects cells from all 3 layers of the epithelium: (1) the basal, (2) intermediate, and (3) superficial layers
  • Cellular material on brush is transferred to a glass slide and flooded with fixative
  • Dry slide sent to pathologist to view with computer assisted analysis
  • Results: negative, positive, atypical
  • “Positive” and “atypical” results require scalpel biopsy to characterize the lesion completely
  • May be a good tool for “monitoring” patients with chronic mucosal changes, such as leukoplakia, lichen planus, post-irradiation, and patients with a history of oral cancer who require long-term surveillance of their ongoing mucosal changes
  • Serves as a trigger for, and not a substitute for traditional scalpel biopsy and histology. This is because brush cytology specimens are disaggregated and architectural information to stage and grade the lesion is absent
