Evaluation of Her-2 protein in histologically tumor-free margins of oral squamous cell carcinoma: An immunohistochemical study.

Background: The status of the 5-year survival rate and loco-regional recurrence in oral squamous cell carcinoma (OSCC) has remained unchanged over the decades. Recent advances in oral cancer research have revealed that the presence of molecular alterations in histologically tumor-free margins of OSCC has a prognostic significance and can aid in designing therapeutic strategies. However, the literature on molecular studies on histologically tumor-free margins is scant, especially in the Indian population.

A comprehensive review of surgical margin in oral squamous cell carcinoma highlighting the significance of tumor-free surgical margins.

Oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral cavity, and surgery is the most accepted line of treatment. The surgical margins (SMs) or resection margins are boundaries of resection specimen excised by the surgeon. The status of these resected SMs is an important and valuable tool to predict the treatment outcome.

Simple bone cyst of mandible mimicking periapical cyst.

Simple bone cysts (SBC) are pseudocysts occurring less commonly in the maxillofacial region. The uncertain and unclear etiopathogenesis led to numerous synonyms to refer this particular cyst. These cysts are devoid of an epithelial lining and are usually empty or contain blood or straw-colored fluid.
