The specimen consists of a segment of tumour nodule removed from the thyroid gland. This is
encapsulated and appears homogenous apart from two pale areas situated in the periphery. These
contain a central focus of haemorrhage. Microscopy showed the tumour nodule to consist of
multiple neoplastic thyroid follicles containing colloid. The tumour exhibited only mild nuclear
pleomorphism, however there was evidence of angioinvasion in one area immediately adjacent to
the tumour capsule.
