T-Cell Large Granular Lymphocytic Leukemia - Case Reports.

T-cell large granular lymphocytic leukemia (T-LGLL) is an uncommon but probably underdiagnosed disease caused by clonal proliferation of large granular lymphocytes. Diagnosis is typically based on the high number of morphologically characteristic lymphoid cells and finding of an abnormal immunophenotype by flow cytometry. Because of its relatively indolent clinical behavior, observation is often an appropriate therapy.

FINE NEEDLE ASPIRATION CYTOLOGY OF ABDOMINAL ORGANS--TEN-YEAR SINGLE CENTER EXPERIENCE.

The aim of the study was to assess the role of fine needle aspiration cytology (FNAC) in the diagnosis of focal changes in solid abdominal organs. A total of 1084 aspirates from intra-abdominal organs including liver, spleen, pancreas and kidneys obtained by ultrasound (US) guidance during a 10-year period were included in the study. The smears were classified as benign, malignant or suspected of malignancy, and unsatisfactory for interpretation.

FINE-NEEDLE ASPIRATION CYTOLOGY OF HEAD AND NECK LYMPH NODES IN A TEN-YEAR PERIOD - SINGLE CENTER EXPERIENCE.

A wide spectrum of diseases including reactive processes, infections, lymphomas and metastatic tumors can cause enlargement of lymph nodes. The present study on 4062 patients with lymphadenopathy was conducted in the Department of Cytology, Sestre milosrdnice University Hospital Center, Zagreb, during a 10-year period. Of 4062 patients with lymphadenopathy, 1624 were males and 2438 were females, age range from several months to 85 years.

[PREOPERATIVE DIAGNOSTICS OF THYROID MEDULLARY CARCINOMA WITH EMPHASIS ON CYTOMORPHOLOGICAL FEATURES AND DIFFERENTIAL DIAGNOSIS OF PRIMARY AND SECONDARY THYROID TUMORS].

Medullary thyroid cancer is a rare neuroendocrine neoplasm that arises from the parafollicular C cells that produce calcitonin, a hormone essential for the regulation of calcium metabolism. It accounts for 4%-10% of all thyroid cancers. In most cases (75%-80%), it is sporadic, while in other cases it is part of the multiple endocrine neoplasia (MEN) syndrome.

[Mast cell leukemia--case report].

Unlabelled: Mast cell leukemia is extremely rare, more often arises de novo and in 15% of cases developes from preexistence mast cell diseases. It is a high malignant leukemia with bad prognosis and a short survival. A 72-year old female was admitted to hospital with clinically suspected plasmocytoma.

[Croatian Society for Clinical Cytology guidelines for thyroid cytology].

The main purpose of thyroid FNA (fine needle aspiration) is to separate malignant and possibly malignant nodules from benign thyroid lesions. Every patient with thyroid nodule is a candidate for FNA. Before a decision to perform an FNA, a complete history, a physical examination directed to the thyroid and cervical lymph nodes, a serum thyrotropin level, and thyroid ultrasound should be obtained.

Simultaneous occurrence of chronic lymphocytic and chronic myeloid leukemia.

The coexistence of chronic lymphocytic (CLL) and chronic myeloid leukemia (CML) in the same patient has only been reported occasionally. Most of these cases represent the patients who developed CLL during the course of CML. Reviewing the literature, only a few cases of simultaneous occurrence of CLL and CML were found.

Aplastic crisis induced by human parvovirus B19 as an initial presentation of hereditary spherocytosis.

The association between aplastic crisis and human parvovirus (HPV) B19 infection has been described in patients with hereditary spherocytosis (HS). Most cases of aplastic crisis in patients with HS induced by HPV B19 have been reported in children and adolescents. In this paper, we describe an aplastic crisis induced by HPV B19 in the 34 year old female as an initial presentation of HS.

Hodgkin's lymphoma variant of Richter's syndrome.

Chronic lymphocytic leukemia/small lymphocitic lymphoma (CLL/SLL) is low-grade malignant lymphoprolipheration, that has tendency to convert to a higher-grade neoplasm over time. More common is the development of a diffuse large cell lymphoma or transformation into prolymphocytic cell population. In rare cases, 0.

Cytological detection of lymphoma in Douglas aspirate.

Except in primary effusion lymphoma (PEL), serous effusions with lymphomatous cells in non-Hodgkin lymphoma (NHL) are not frequently seen as first manifestation of disease. In NHL lymphoplasmacytic lymphoma (LPL) the spleen, lymph nodes, and bone marrow are frequently sites of disease and this type of NHL is usually associated with a serum paraprotein of IgM type accompanied by the clinical syndrome of Waldenström macroglobulinemia. Our patient with NHL LPL type presented in this report had less frequently seen involvement of gastrointestinal tract and clinically was first manifested as effusion in Douglas space.
