The borders of the nodule - case conp 051

Nodular goiter

Next

Clinical presentation: A 69-year-old woman came to a regular follow-up investigation. We examined her 5 years ago when she had a nodule with the dimensions of 8x8x13 mm. FNA was performed and it gave a benign result. The patient had no complaints.

Palpation: a moderately firm nodule in the right lobe.

Results of blood tests: euthyroidism (TSH-level 1.05 mIU/L).

Ultrasonography: The thyroid was echonormal. A moderately hyperechogenic, inhomogeneous nodule was present in the right lobe with the dimensions of 10x11x13 mm. It means that the volume of the nodule increased from 0.4 ml to 0.75 ml in 5 years. The nodule presented increased intranodular blood flow.

Cytological picture. There was no colloid in the background. A few atypical clusters were present. A great proportion of follicular cells exhibited nuclear groove, a few cells did inclusion.

Clinical-cytological diagnosis: papillary carcinoma.

Histopathology: multifocal papillary carcinoma.

Comments.

  1. We reviewed the original smears which have gained for 5 years. There were only a few cells on the smear without any atypia. The correct diagnosis would be not diagnostic.

  2. The borders of the nodule are blurred. The degree of protrusions is close to the pathological level, therefore irregular margins should also be considered.
