Coexistence of Hodgkin Lymphoma and Squamous Cell Carcinoma of the Tongue: A Case Report and Literature Review.

We report an unusual case of a 39-year-old male patient with a previous history of treated classical Hodgkin lymphoma, presenting with tongue ulcer and left ear pain who was subsequently diagnosed with invasive squamous cell carcinoma of the oropharynx. This case highlights the importance of vigilance in patients with a history of lymphoma and the potential for the development of secondary malignancies. We discuss the clinical, radiological, and pathological findings and emphasize the need for close monitoring and early intervention in such cases.
