Metastatic medullary thyroid carcinoma to the breast in a patient with combined medullary and papillary carcinoma of thyroid--a case report.

We report the fine-needle aspiration cytology of a case of medullary thyroid carcinoma (MTC) metastatic to the breast in a 66-year old female within two years of diagnosis of the thyroid tumor. The aspirate of the breast metastases revealed a plasmacytoid population of cells in loose clusters and singly with mild to moderate pleomorphism. Nuclear groves and occasional intranuclear cytoplasmic inclusions were seen.

Fine needle aspiration cytology of Hodgkin's lymphoma: A cytohistologic correlation study from a cancer center in Kuwait.

Objective: To assess the diagnostic accuracy offine needle aspiration cytology (FNAC) in the diagnosis of Hodgkin's lymphoma (HL).

Study Design: We selected all the cases in which a cytologic diagnosis of HL, suggestive of or suspicious for HL, or HL as the prime differential diagnosis was offered on FNAC. These cases were correlated with histopathologic follow-up.

Combined applications of fine needle aspiration cytology and flow cytometric immunphenotyping for diagnosis and classification of non Hodgkin lymphoma.

Aims And Objectives: In this present study we have evaluated the feasibility of sub-classification of non-Hodgkin's lymphoma (NHL) cases according to World Health Organization's (WHO) classification on fine needle aspiration cytology (FNAC) material along with flow cytometric immunotyping (FCI) as an adjunct.

Materials And Methods: In this five years study, only cases suggested or confirmed as NHL by FNAC were selected and FCI was performed with a complete panel of antibodies (CD3, CD2, CD 4, CD5, CD8, CD7, CD10, CD19, CD20, CD23, CD45, kappa and lambda) by dual color flow cytometry. Both cytologic findings and FCI data were interpreted together to diagnose and sub-classify NHL according to WHO classification.

Role of fine needle aspiration cytology in nodular sclerosis variant of Hodgkin's lymphoma.

Objective: To assess the efficacy of fine needle aspiration cytology (FNAC) in the diagnosis of nodular sclerosis variant of Hodgkin's lymphoma (NSHL) and to analyze cytologic features that could help in subtyping a case of Hodgkin's lymphoma into this variant.

Study Design: FNAC smears of 18 histopathologically proven cases of NSHL were analyzed for a variety of features.

Results: On initial cytologic assessment, 14 of 18 cases were diagnosed as Hodgkin's lymphoma.

Fine needle aspiration cytology of the thyroid: a cytohistologic study with evaluation of discordant cases.

Objective: To analyze the diagnostic efficacy of fine needle aspiration cytology (FNAC) in the initial evaluation of thyroid nodules, with special emphasis on discrepant cytologic diagnoses.

Study Design: A total of 192 thyroid fine needle aspirates with subsequent histopathologic follow-up were analyzed. The cytologic diagnoses were divided into 4 categories: positive for malignancy, negative for malignancy, indeterminate for diagnosis and nondiagnostic.
