A 39-year-old woman was referred to our hospital for invasive cervical cancer. On initial physical examination, inguinal lymph nodes, but not supraclavicular lymph nodes, were palpable. Positron emission tomography revealed multiple bone metastasis with hypermetabolic lymph nodes in the abdominal and pelvic cavity, left supraclavicular fossa, and a mild hypermetabolic nodular lesion in the left thyroid (Fig. 1A). Gun biopsy was performed for the left supraclavicular lymph node. Ultrasonography indicated the left thyroid nodule was a 1 cm sized hypoechoic lesion with inner calcification (Fig. 1B). Papillary thyroid carcinoma was diagnosed with fine needle aspiration (Fig. 1C). A lymph node specimen revealed synchronous metastasis from a double primary origin (Fig. 2A, ×40). One metastatic lesion (Fig. 2B, blue square, ×100) showed papillary growth and was positive for thyroglobulin immunohistochemical stain (Fig. 2C, ×100), consistent with thyroid carcinoma. Another metastatic lesion (Fig. 2D, yellow square, ×100) was negative for thyroglobulin (Fig. 2E, ×100). Immunohistochemical staining was positive for p16 (Fig. 2F, ×100) and p63 (Fig. 2G, ×100), verifying metastatic squamous cell carcinoma. Final diagnosis was advanced cervical cancer (stage IVb), and she received palliative chemotherapy. For thyroid cancer, low dose thyroxine was given for 3 months after confirming normal thyroid function and lost to follow-up.
