Currently accepted histological classification of FTC is inadequate and fails to accurately predict patients with distant metastatic disease and a more aggressive clinical course. It is thus the policy of our unit to recommend total thyroidectomy and radioactive iodine ablation for all patients with FTC.

Mesothelial inclusion cyst is a rare benign tumour that has only 130 cases reported in the literature. Accurate diagnosis and optimal management of this condition remains uncertain. We report a 51-year-old African gentleman, whom presents with abdominal pain and constipation. A computed tomography scan was performed and revealed a large cystic lesion in the right paracolic gutter. The differential diagnosis included appendiceal mucinous neoplasm, cystic tuberculosis and duplication cyst. A laparotomy was performed due to his symptoms and size of the cyst. Macroscopically, the tumour had a size of 25 × 10 × 10 cm and revealed a necrotic lymph node. It was resected en bloc with the appendix and an ileocolic anastomosis performed. Histology revealed a diagnosis of mesothelial inclusion cyst and acute appendicitis. The patient recovered well and had no recurrence at 2-year follow-up.
