Chronic Traumatic Ulcer of the Tongue. Two Case Reports Highlighting Diagnostic Challenges and Malignancy Mimicry

This case report highlights a traumatic ulcer mimicking oral squamous cell carcinoma (SCC). Oral ulcers, commonly caused by trauma, often present diagnostic challenges. Two male patients, aged 25 and 90, reported painful solitary lingual ulcers resembling malignancy. A biopsy was performed, leading to significant regression and complete healing. Initially misdiagnosed as SCC, the ulcers required careful clinical evaluation, medical history review, and additional investigations for accurate diagnosis. Histopathology confirmed the diagnosis, emphasizing biopsy’s role in both diagnosis and healing. This report highlights the importance of biopsy in distinguishing traumatic ulcers from malignancy and facilitating proper management.
