- Abstract: Simultaneously occurring malignancies may be detected in different organs or tissues at any given time. Patients diagnosed with a tumor may be found to have another tumor or second primary cancer. Second primary cancers (SPCs) may be further classified as synchronous or metachronous. Synchronous SPCs are lesions detected simultaneously or within 6 months after the diagnosis of the primary tumor while metachronous SPCs are tumors diagnosed 6 months after primary tumor diagnosis.1There is an increased risk of having second primary cancer in Head and Neck Squamous Cell Carcinoma (HNSCC) patients.1 In a study by Strojan et al. in 2013, among 2,106 head and neck cancer patients, 2.4% developed synchronous second primary cancers.2 A systematic review by Coco-Pelaz et al. in 2020, showed that second primary tumors most frequently occur in the head and neck area followed by the lungs and esophagus.3We present a case of follicular thyroid carcinoma with an incidental finding of cervical lymph-node metastatic squamous cell carcinoma from the tonsil and discuss the clinical presentation, ancillary procedures and management.
