Synchronous dual malignancy of papillary carcinoma thyroid and squamous cell carcinoma tongue: A case report

Introduction: Patients with thyroid carcinoma have increased risk for development of second malignancy either synchronous or metachronous. We are reporting a rare case of synchronous squamous cell carcinoma oral tongue and papillary thyroid carcinoma. Case Report: A 60-year-old smoker male was presented with the complaints of non-healing ulcer (2x2 cm) at right anterolateral tongue since six months. Excision biopsy of tongue ulcer was reported as pT 0.8x0.8 cm, moderately differentiated squamous cell carcinoma. Wide local excision of tongue lesion with right modified neck dissection was done. Histopathology was reported as no residual primary tongue tumor seen, 1 out of 28 lymph nodes showed metastatic deposits of squamous cell carcinoma. Unexpectedly another one lymph node was positive of metastatic thyroid papillary carcinoma. Total thyroidectomy with central compartment neck dissection and left modified neck dissection was done. Histopathology was reported as pT 2x1 cm, papillary carcinoma right lobe of thyroid, 7 out of 32 lymph nodes showed metatstatic paillary carcinoma thyroid. Although exact cause of second malignancy is unknown but field cancerization, genetic predisposition, history of prior radiation or chemotherapy, improved survival can be attributed for increased incidence of second cancer. Conclusion: Double malignancies require multidisciplinary management approach. (This page in not part of the published article.)
