Presentation
Palpable mass lesion of thyroid.
Patient Data
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
A poorly defined, solid mass in the left lobe of the thyroid. The lesion contains calcification and has no pseudocapsule. Note how the mass infiltrates the thyroid parenchyma.
Case Discussion
The findings pre-biopsy are highly suspicious for thyroid malignancy. If the pseudocapsule disappears and you lose the interface between the lesion and the normal parenchyma, be careful. The presence of microcalcifications is a second indication for FNA. This is a confirmed papillary carcinoma of the thyroid.
Compare with case 18565.
