Modified Cajal's trichrome stain in oral squamous cell carcinoma.

Background: Modified Cajal's trichrome stain (MCTS) is a good differential stain that allows one to visibly distinguish between connective tissue and epithelial elements with different tonalities of colour.

Aim: Our study aims to evaluate and analyse the effectiveness of oral squamous cell carcinoma (OSCC) using MCTS.

Materials And Methods: A study was conducted retrospectively with 30 tissue blocks embedded in paraffin from cases of OSCC that have been confirmed by histopathology.

Comparative study of conventional exfoliative cytology and centrifuged liquid-based cytology in oral leukoplakia and oral squamous cell carcinoma patients.

Background: This study aims to compare the efficacy between conventional exfoliative cytology (EC) and centrifuged liquid-based cytology (CLBC) in control, leukoplakia, and oral squamous cell carcinoma (OSCC) patients. Oral leukoplakia and oral cancer require an early definitive diagnosis for better prognostic outcome. Oral EC, a minimally invasive technique that involves the examination of desquamated cells from the tissue surfaces used as a method of early diagnosis.

Expression of HIF-1α and Nestin in oral squamous cell carcinoma and its association with vasculogenic mimicry.

Aim: To evaluate and correlate the expression of HIF1-α and Nestin in tumor center and periphery of nonmetastatic, and recurrent oral squamous cell carcinoma (OSCC) and its association with vasculogenic mimicry.

Materials And Methods: About 60 histopathological proven cases of OSCC with proper tumor center and periphery were collected. Among them 25 are nonmetastatic, 25 metastatic, and 10 recurrent cases of OSCC.
