Diagnostic Complexities of Oral Squamous Cell Carcinoma.

Prompt diagnosis of oral cancers is critical to increase survival rates. Treatment for oral squamous cell carcinoma (OSCC) and oropharyngeal squamous cell carcinoma (OPSCC) is mainly driven by cancer stage and may include surgery alone or surgery with adjuvant or neoadjuvant radiation, chemotherapy, and/or targeted therapy. This article describes a case of a patient who was referred by his general dentist to an oral medicine clinic for assessment of an exophytic lesion on the left lateral tongue. The case report discusses the differential diagnosis and treatment, examining critical elements in lesion assessment in the patient, who had a significant oral lesion history and who was ultimately diagnosed with OSCC. Highlighting various complexities that may arise in the diagnosis of OSCC, the article underscores the importance of surveillance, informed biopsy technique, and accurate interpretation of pathology reports to appropriately manage patients with potential oral malignancy.
