Rapid Cytologic Diagnosis of Surgical Specimens

Amyloid in cytologic specimens. Differential diagnosis and diagnostic pitfalls.

OBJECTIVE To describe and illustrate the characteristic features of amyloid in cytologic preparations and point out its diagnostic pitfalls. STUDY DESIGN Five fine needle aspirates and one bronchial washing that contained amyloid were retrospectively reviewed. The aspirates were obtained from each of the five following sites: lung, occipital lymph node, thyroid gland, proximal humerus and sub...

Ancillary studies on neoplastic cytologic specimens.

Fine-needle aspiration (FNA) is a safe, simple, rapid, and cost-effective procedure that is often used as an initial diagnostic modality to work up primary and metastatic tumors at almost any body site. FNA allows acquisition of samples not only from superficial and large lesions, but also from smallor deep-seated lesions, or from multiple lesions during the same biopsy procedure. It provides v...

Compression of Histopathology, Culture and Rapid Urease Test in Diagnosis of Helicobacter Pylori in Gastric Biopsy Specimens

Abstract Background and Objective: Helicobacter pylori (H. Pylori) infection is related to chronic gastritis, peptic ulcer, duodenal ulcer and gastric cancer. Thus, identification and treatment of the infection have a considerable importance. The aim of this study was to compare three methods of Histopathology, Culture and Rapid Urease test (RUT) in identification of H. Pylori in gastric bio...

Cytologic diagnosis in bronchoalveolar lavage specimens. A diagnostic technique for lung neoplasmas with a peripheral location.

Morphologic features of endometriosis in various types of cytologic specimens.

Endometriosis is defined as the presence of endometrial tissue outside the uterine cavity. This study evaluates the cytomorphologic features of endometriosis in various cytologic specimen types [fine-needle aspiration (FNA), effusion cytology (EF), touch imprint (ToP), and cervical smear (PAP)], and assesses the key elements helpful in recognizing this lesion. A total of 18 cases (8 FNA, 4 EF, ...
