CYTOLOGICAL DIAGNOSIS OF THYROID TUMOURAL PATHOLOGY: PRESENT AND FUTURE I. Amendoeira IPATIMUP, Porto, Portugal Having the histological classification of malignant tumours of the thyroid – differentiated carcinomas (papillary carcinoma, follicular carcinoma, well differentiated carcinoma NOS and medullary carcinoma), Hürthle cell carcinomas, poorly differentiated carcinomas and undifferentiated carcinomas, as a frame, we will summarize the main problems of the cytological diagnosis of thyroid… 



Pattern of expression of intermediate cytokeratin filaments in the thyroid gland: an immunohistochemical study of simple and stratified epithelial-type cytokeratins

Papillary carcinoma of the thyroid presents a distinct CK profile that may be used for diagnostic purposes, and papillary and follicular thyroid carcinomas shared the expression of simple epithelial-type CKs 7, 8, 18 and 19.

Fine Needle Aspiration Cytology and Immunocytochemistry of Metastatic Melanoma

It was found that an immunological characterization was necessary to conclusively diagnose over 50% of metastatic melanomas which presented with an equivocal cytological picture.

Cytomorphology and immunocytochemistry of fine needle aspirates from blastic non-Hodgkin's lymphomas.

The high diagnostic accuracy of combined cytomorphologic and immunocytochemical assessment of FNA samples validates the use of the technique in the diagnostic work-up of blastic (high-grade malignant) NHLs.

T‐Cell-Rich B‐Cell Lymphoma

Five cases of B-cell lymphoma are described in which the morphology and initial immunohistochemistry suggested a diagnosis of T-cell neoplasia, and it was revealed that the B-cells constituted the neoplastic population.

T‐cell‐rich B‐cell lymphoma: Fine‐needle aspiration cytology and immunocytochemistry

It can be concluded that immunocytochemistry in conjunction with cytomorphology on fine‐needle aspirates will allow a conclusive diagnosis of T‐cell‐rich B‐cell lymphoma and its differentiation from Hodgkin's disease and T‐ cell lymphomas.

Fine needle aspiration (FNA) in the diagnosis of soft tissue tumours; a review of 22 years experience

Cytodiagnostic details of the most common soft tissue tumours and their differential diagnoses are presented, particularly in the paediatric small/round cell tumours.

Fine‐needle aspiration cytology and immunocytochemistry of Hodgkin's disease, suppurative type

Immunocytochemistry identified the large atypical cells as CD 30 (BerH2)‐positive and negative for CD 45 (LCA) in cytospin material from 2 patients, which allowed a conclusive diagnosis of HD.
