Solid variant of papillary thyroid carcinoma in a 14-year-old girl

Solid variant of papillary thyroid carcinoma (PTC) is a rare, poorly characterised variant and predominantly reported in children with a history of radiation exposure. This variant has a high propensity for extra-thyroidal extension and cervical lymph node metastases. A 14-year-old Malay girl who had no history of radiation exposure, presented with multiple cervical lymphadenopathy and it was clinically suspicious for tuberculosis or lymphoma. An incisional biopsy revealed a metastatic PTC. The patient underwent total thyroidectomy with bilateral lateral neck dissection and histopathology report was solid variant of PTC. Whole-body I 131 scan was performed which revealed an intense tracer uptake in the neck. She was planned for radioactive iodine ablation and now on regular follow-up for monitoring of possible tumour metastasis.
