Papillary Carcinoma Thyroid Co-existing with Upper Aerodigestive Tract Squamous Cell Carcinoma: Case Series

Abstract

The incidental discovery of papillary carcinoma of thyroid in a patient being investigated for squamous cell carcinoma of oral cavity is a rare clinical situation and appropriate management may vary from what was actually planned. We report a case series of 10 patients admitted with variable complaints of pain on swallowing, change in voice and breathing difficulty. Total Laryngectomy was done along with lymph node neck dissection. On histopathological examination, it showed poorly differentiated Squamous cell carcinoma. Tissue sent as paratracheal lymph node showed thyroid tissue with foci of Papillary carcinoma of thyroid which was a coincidental finding. A total of 10 cases with dual malignancy of Upper aerodigestive tract Squamous cell carcinoma coexisting with Papillary carcinoma thyroid as an incidental finding. Of which nine were male and one was female, had undergone Total Laryngectomy, Hemiglossectomy and Hemimandibulectomy was done along with lymph node neck dissection.
