A retrospective review of 35 FNA cases with the diagnosis of Hürthle cell lesion or Hürthle cell neoplasm was performed. In each case, there was a subsequent surgical excision.

Fine-needle aspiration of adrenal cortical carcinoma: cytologic spectrum and diagnostic challenges.

We reviewed the cytologic features of 20 adrenal cortical carcinomas (ACCs; 9 primary and 11 metastatic) from 19 patients and highlighted diagnostic pitfalls. The mean size of primary ACCs was 11.9 cm, and that of metastatic ACCs was 3.

Fine needle aspiration cytology of well-differentiated papillary mesothelioma: a case report.

Fine-needle aspiration cytology of a liver metastasis of follicular dendritic cell sarcoma.

Follicular dendritic cell sarcoma (FDCS) is an uncommon neoplasm derived from FDCs in lymphoid tissue. Metastatic FDCS to the liver is rare. We present a case of a 65-yr-old woman who was referred to our institution 1 mo after splenectomy for FDCS of the spleen.

Fine-needle aspiration cytology of blastic natural killer-cell lymphoma (CD4+ CD56+ hematodermic neoplasm).

We describe fine-needle aspiration (FNA) cytology findings of a case of blastic natural killer (NK)-cell lymphoma. The patient was a 68-year-old man who was diagnosed with cutaneous blastic NK-cell lymphoma involving his forehead. He developed a 1.
