Anaplastic Thyroid Carcinoma Histologically Mimicking a Plasmacytoma

Anaplastic thyroid carcinoma

Anaplastic Thyroid Carcinoma

Thyroid cancers represent about 1% of all human cancers. Differentiate thyroid carcinomas (DTCs), papillary and follicular cancers, are the most frequent forms, instead Anaplastic Thyroid Carcinoma (ATC) is estimated to comprise 1-2% of thyroid malignancies and it accounts for 14-39% of thyroid cancer deaths. The annual incidence of ATC is about one to two cases/million, with the overall incide...

Anaplastic Thyroid Carcinoma: A Therapeutic Dilemma

Anaplastic thyroid carcinoma (ATC) is one of the most malignant human neoplasms and has a grave prognosis. This study gives an update on our experience with this unusual neoplasm, with specific focus on the response to various treatment modalities. Forty-seven patients with histologically proven ATCs were enrolled (19 men, 28 women; mean age, 62.8 years). This number represents 1.5% among a tot...

Small Lymphocytic Lymphoma of the Thyroid Mimicking Plasmacytoma

Primary thyroid gland lymphomas (PTLs) typically occur in middle-to older-aged individuals in the setting of lymphocytic thyroiditis with a predilection for females. Diffuse large B-cell lymphoma is the most frequent histologic subtype of thyroid lymphomas. Small lymphocytic lymphoma (SLL) belongs to the least common subtypes of thyroid lymphoma. It is often associated with the involvement of l...

Anaplastic transformation of differentiated thyroid carcinoma.

Anaplastic thyroid cancer (ATC) is one of the most aggressive malignancies that arise from transformation of pre-existing differentiated thyroid cancer (DTC). However, the carcinogenic mechanism of anaplastic transformation remains unclear. We describe a case for huge goiter diagnosed as papillary thyroid carcinoma, which underwent thyroidectomy. The final histology showed anaplastic transforma...
