The Current and Future Impact of Lymph Node Fine-Needle Aspiration Cytology on Patient Care.

Lymph node (LN) fine-needle aspiration cytology (FNAC) is a common diagnostic procedure for lymphadenopathies. Despite the qualities and potentialities of LN-FNAC, the number of possible pathologies and the variety of clinical contexts represent a challenge and require a continuous upgrading of the procedure according to the emerging clinical requests and new technologies. This study presents an overview of the current and future impact of LN-FNAC on the care of patients with lymphadenopathy.

Overexpression of BAG3 (Bcl2-associated athanogene 3) in serum and skin of patients with systemic sclerosis.

Objectives: BAG3 (Bcl2-associated athanogene3) is able to induce the transformation of cancer-associated fibroblasts to alpha smooth muscle actin (a-SMA) positive (+) myofibroblasts. In systemic sclerosis (SSc), a-SMA+ myofibroblasts also play an important role in the progression of fibrosis in the skin and involved internal organs. The aim of the study was to investigate whether BAG3 is overexpressed in SSc and may be a biomarker of fibrogenesis.

Combined fine needle aspiration cytology and core needle biopsy in the same setting: A two-years' experience.

Introduction: Fine needle aspiration cytology (FNAC) combined with rapid on-site evaluation (ROSE) and ancillary techniques is an accurate diagnostic tool for many pathologies. However, in some cases, it may not be sufficient for actionable diagnoses or molecular testing, especially for cases that require large immunohistochemical panels or cases in which histological features are mandatory for the diagnosis. Core needle biopsy (CNB), on the contrary, provides samples that are suitable for histological features and sufficient for all ancillary studies.

Observations on hematogones with light chain restriction.

Light-chain restricted hematogones (LCR HGs) detected by flow cytometry (FC) may, occur in bone marrow mimicking involvement by a B-cell lymphoma. This phenomenon can present a diagnostic pitfall and negatively impact patient management, and may occur in other organs, including lymph nodes, For this reason, it is recommended to utilize, in case of LCR in lymph node, one additional morphological, phenotypical or molecular criteria for the diagnosis of lymphoma on cytological samples.
