Immunohistochemical Expression of Basement Membrane Laminin in Histological Grades of Oral Squamous Cell Carcinoma: A Semiquantitative Analysis.

Background: Oral squamous cell carcinoma (OSCC) is a prevalent malignancy characterized by varying histological grades. Basement membrane laminin expression plays a crucial role in tumor invasion and progression. This study aimed to assess the immunohistochemical expression of basement membrane laminin in different histological grades of OSCC.
