HISTOPATHOLOGICAL ANALYSIS OF VERRUCOUS CARCINOMA WITH PAS STAIN TRANSFORMING INTO INVASIVE SQUAMOUS CELL CARCINOMA

Ackerman’s tumour commonly known as Verrucous carcinoma (VC) is a low grade variant of oral squamous cell carcinoma (OSCC). The oral cavity and larynx have been reported to be the commonest sites of involvement in the head and neck regions. VC is characterised with presence of minimal degree of dysplasia and biological aggressiveness, the principal etiological factor being tobacco usage. Its distinctive histopathological features make it exigent for diagnosis and build a close association between the clinician and the histopathologist. Hereby we report a rare case of verrucous carcinoma on the right buccal mucosa of a 48 year old male patient progressing into invasive squamous cell carcinoma.
