Large papillary thyroid cancer bed recurrence causing overlying skin ulceration and bleeding
Abstract
Salvage surgery is an acceptable option for palliative treatment of thyroid bed recurrence in metastatic papillary thyroid carcinoma when other non-invasive options fail to control local skin complications.
A 86-year-old female patient presented to the emergency department with active bleeding from an ulcerated large anterior neck mass. The patient underwent right hemithyroidectomy 18 years prior for a low risk for recurrence stage I pT1bpN0M0 papillary thyroid cancer (PTC) followed 1 year after by completion thyroidectomy plus right central-neck dissection. Pathology was notable for a stage III pT1pN1M0 PTC with intermediate risk for recurrence. However, the patient declined adjuvant RAI and follow-up. Upon admission, clinical examination revealed a large, freely-mobile, non-tender, soft anterior neck mass covered by a network of enlarged veins with multiple skin ulcerations (Figure 1). The patient was under levothyroxine treatment. Thyroid function and serum Tg-antibodies were normal, and serum Tg was 237 ng/ml. Neck-ultrasound depicted a U5 (malignant) 81 × 42 × 55 mm solid hypoechoic nodule with irregular outline, microcalcifications, and increased intranodular vascularity. FNA was suggestive of PTC. CT revealed a solid irregular with increased vascularity thyroid-bed nodule without lymph-node involvement (Figure 2). PET/CT revealed extensive metastization into lung.


1 QUIZ QUESTION: WHAT ARE THE TREATMENT OPTIONS?
Based on patient's advanced age and extensive metastatic disease, palliative non-medical (radioactive iodine therapy, targeted therapy, chemotherapy) treatment was initially decided.1 However, as active bleeding from the ulcerated skin surface did not respond to local silver nitrate treatment, and external beam radiation therapy and electrochemotherapy were not available,2 salvage resection of the large thyroid bed PTC recurrence performed with uneventfull recovery (Figure 3A,B).
