Neglected papillary thyroid carcinoma seven years after initial diagnosis.

Papillary thyroid carcinoma (PTC) is the most common epithelial thyroid tumor, accounting for more than 80% of all thyroid tumors. Recent advances in ultrasonographic screening and US-guided fine-needle aspiration biopsy (FNAB) have facilitated the early detection and diagnosis of papillary thyroid carcinomas. In exceptionally rare cases, papillary thyroid tumors may assume enormous dimensions due to recurrent disease or the patient's negligence of the problem. We report an extremely rare case of a 72-year-old woman presented with a neglected giant exophytic papillary thyroid carcinoma with hemorrhagic ulcers. Computed tomography showed a mass measured 17 × 12 cm that caused a displacement of the trachea to the right side and reached the mediastinum. After bleeding management, patient was discharged. The patient was fully aware of her situation, but she denied any further therapeutic management.
