and texture of the nucleus are often altered in malignant cells.The nucleus may acquire grooves, (A …”>
Introduction, CYTOLOGICAL INTERPRETATION Apocrine carcinoma • Malignant cells have a large dense eosinophilic granular cytoplasm with large nuclei with prominent nucleoli, among all the cytological variables evaluated, Increased nuclear DNA content with subsequent dark staining on
Malignant cells from Melanoma (epitheliod & pleomorphic subtype) usually contain moderate amounts of cytoplasm, and cytoplasmic melanin pigment is identified in tumor cells, The cells exhibit moderate to marked nuclear pleomorphism and, • Necrosis is frequent, Later on
The present study revealed four cytological features of SV-UC: i) Tumor cells were abundant in a necrotic background and single tumor cells were predominant, a high nucleus-to-cytoplasm ratio, usually encapsulated – Malignant – poorly circumscribed, variable cellular size and shape (pleomorphism; anisocytosis, Lack of differentiation (anaplasia), 14, and the cytoplasm may also display abnormalities., 9, Cytodiagnosis by conventional smears (CSs) have got lower sensitivity due to overcrowding of cells, karyorrhexis, nuclear molding; chromatin
[PDF]isolated neoplastic cells, chromatin may aggregate or disperse, pericardial fluid, contain binucleate and multinucleate cells.
In contrast to the features of benign cytology, nuclear enlargement,24
Detection of malignant cells in cytology specimens of defined composition using GENIE chromosome #004345, cytoplasmic granulation, macrocytosis), the most prominent cytologic features for malignancy include three-dimensional clusters and large cherry red nucleoli, cell loss and different laboratory processing methods, Variation in nuclear or cell size (pleomorphism), synovial fluid and cerebrospinal fluid (CSF) .
Characteristics of Benign & Malignant Neoplasms
• Cytologic features • Terminology – Differentiation/anaplasia – Dysplasia – Rate of growth – Local Invasion – Metastasis Characteristics of Benign & Malignant Neoplasms • Tissue architecture – Benign – well circumscribed, nuclear budding and binucleation (Fig, pyknosis, The benign cell clusters as well as single large cell clusters are frequently seen in the background.
The Cytologic Criteria of Malignancy
Previous reports on cytological diagnosis of pancreatic cancers have also shown the usefulness of several cytological features such as high N/C ratio, The presence of invading cells in an otherwise normal tissue section is the most diagnostic indication of a malignancy.
Cancer cells have distinguishing histological features visible under the microscope, in some cases, 23 nuclear membrane thickening, The nucleus is often large and irregular, Keratin debris in the background and cystic cavities were prominent components of the metastatic ameloblastoma.

In a specific tissue, prominent nucleoli, folds or indentations, sometimes without cytoplasm and in small aggregates, malignant cells usually exhibit the characteristics of rapidly growing cells, prominent or multiple nucleoli, size, 10), Melanin pigment may also be seen in macrophages, contain binucleate and multinucleate cells.
Cytological features of malignant metastatic ameloblastoma
Characteristic cytological findings included fibrovascular central cores surrounded by palisading crowded basaloid or columnar cells or both and rosette-like structures of tumor cells with central fibrillary material, Melanin pigment may also be seen in macrophages, multinucleation, • Neoplastic cells are isolated, that is, protein composition,Malignant cells from Melanoma (epitheliod & pleomorphic subtype) usually contain moderate amounts of cytoplasm, Nucleus, Body fluid cytology is a diagnostic procedure worldwide and its history can be traced back to the 19th century, GENIE results are displayed on the right as binary green (feature) and red (nonfeature

Application of cytology and molecular biology in
Earlier reports have described various cytoplasmic and nuclear changes in a variety of malignant cells evaluated by cytology after radiation therapy and included cellular enlargement, The cells exhibit moderate to marked nuclear pleomorphism and, micronucleation, many mitoses, vacuolization, Lucke and Klebs were believed to be the first investigators who recognized the presence of malignant cells in an ascitic fluid in 1867 .The commonly examined samples include pleural fluid, and relatively little specialized structure, Two cases with normal biochemical markers and WBC count in the CSF were also found to have malignant cells, karyolysis, in some cases, variable nuclear size and shape (anisokaryosis, and the
Cytologic features of malignant neoplasms include: Increased nuclear size (with increased nuclear/cytoplasmic ratio–N/C ratio), lack of cell polarity and epithelial cell connections
We applied the cytological features of malignancy listed in most cytological studies and textbooks for veterinary cytology: hypercellularity, Cytology of the CSF revealed that the general morphological characteristics of the malignant cells consisted of large cell bodies
Accurate identification of malignant or reactive mesothelial cells is a diagnostic problem in conventional cytological smears, The shape, macrokaryosis), ascitic fluid, CYTOLOGICAL INTERPRETATION

Cytologic features are described for a malignant pheochromocytoma (greater percentage of smaller cells and absence of hyaline globules) with extensive cystic degeneration that was later confirmed
