Extramedullary hematopoiesis (EMH) is a compensatory mechanism that occurs when the marrow is unable to maintain sufficient red cell mass. EMH generally occurs in the patients with deficient bone marrow hematopoiesis secondary to either peripheral red cell destruction or marrow replacement. Although EMH is known to occur in agnogenic myeloid metaplasia with myelofibrosis, chronic myelogenous leukemia, thalassemia, and infiltrative disorders, such as lymphomas, it is rare in acute leukemias. EMH is most commonly seen in the liver and spleen as a diffuse lesion...

Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, whereas primary thyroid lymphoma is very rare. Here, we report a case in which a right-sided nodule measuring 4.3 × 2.2 cm was examined using fine-needle aspiration biopsy. This revealed abundant monomorphic non-cohesive large lymphoid cells without thyroid follicular cells, on which basis acytodiagnosis of lymphoma coincident with lymphocytic thyroiditis was made. Subsequent histologic examination revealed CD45-, CD20+, and Bcl-6 + and cytokeratin-, CD3-, CD5-, and CD30-negative tumor cells arranged diffusely in the whole thyroid coexisting with a separate PTC nodule sized 1...

Primary lung epithelial malignancies are the most common neoplasms among all pulmonary tumors. Lung cancer (LC) is the leading cause of cancer-related mortality for which a histologic or cytologic confirmation of malignancy is required before treatment. Specimen management is an important task for pathologists in the field of LC. Biopsy and fine needle aspiration are comparable. It is desirable to have both for diagnosis and mutation testing to maximize their use for patient care.

Preoperative pathologic diagnosis of pelvic tumors is mandatory for proper management of patients like neoadjuvant chemotherapy and interval debulking. Currently there are many minimally invasive methods available which include fine-needle aspiration cytology (FNAC) and trucut biopsy, mostly complimentary to each other. FNAC is a cheap, rapid and sensitive method for diagnosis of pelvic tumors. It can be done as an outpatient procedure without complications. But with it, the tissue architecture cannot be seen...

The triple test lies at the heart of preoperative diagnosis of breast lesions. Raised awareness and self-assessment have significantly increased the rate of detection of breast pathologies. The managing clinicians usually decide the imaging and pathological modalities to the best interest of the patients. Core needle biopsy (CNB), cell-block studies, and fine needle aspiration cytology (FNAC) coupled with rapid on-site evaluation (ROSE) have significantly increased the accuracy of preoperative diagnosis. Immunocytochemistry, immunohistochemistry on cell blocks, and other ancillary studies give confidence to the clinicians to decide the best treatment strategies...

Thyroid and salivary gland are amongst the most common sites subjected to fine needle aspiration cytology (FNAC) due to easy accessibility of these sites along with high diagnostic accuracy of FNAC. The performance of FNAC can be increased with the use of ultrasonographic guidance and rapid on-site evaluation. Cell block along with immunochemistry and other ancillary techniques further helps in clinching the correct diagnosis in certain diagnostically challenging cases. Core needle biopsy (CNB) is proposed to have a better diagnostic accuracy in certain situations...

Demonstration of acid fast bacilli (AFB) is essential for the definitive cytodiagnosis of tuberculosis. However, it is not seen in all cases of tuberculosis, being more commonly observed in necrotic lesions. Tuberculosis shows a spectrum of lesions that form a continuum extending from good immunity end with purely granulomatous lesions to poor immunity end with purely necrotic lesions. Each stage has distinctive microscopic picture and determines the chance of finding AFB. AFB yield was the highest (92.7%) in necrotic lesions containing eosinophilic structures (ES)...

Some of the limitations of fine needle aspiration (FNA) in the cytodiagnosis of lymphoma include problems encountered in differentiating reactive hyperplasia from low-grade non-Hodgkin lymphoma (NHL), lower cytodiagnostic accuracy for NHL with a follicular (nodular) pattern and nodular sclerosis type of classical Hodgkin lymphoma (HL), and overlapping morphological features between T-cell-rich B-cell lymphoma (TCRBCL), anaplastic large cell lymphoma (ALCL), and HL. Immunocytochemistry may be of help in such situations...

Objective: To assess the performance of fine needle aspiration cytology (FNAC) in the diagnosis of tuberculosis mastitis. Materials and Methods: Diagnostic test performance evaluation using two methods-as compared to an alloyed gold standard as well as in the absence of a gold standard. Alloyed gold standard combined the results of acid fast bacilli in cytology smears, histopathological confirmation, and response to treatment. Bayesian estimation of test parameters was done in the absence of the gold standard...

Background: Pap-smears-based cytology and human papilloma virus testing have their own limitations in detecting cervical precancerous lesions, and still need further standardization. Co-expression of p16ink4a and Ki-67 can be used as additional biomarker. Aims: To study the role of liquid-based cytology and the dual immunostaining for p16/Ki-67 in predicting the presence of significant lesion in cases of mild cytological atypia. Materials and Methods: A prospective, cross-sectional study was performed in the Department of Pathology, in collaboration with Department of Obstetrics and Gynecology over 15 months including 545 patients...

Context: Fine-needle aspiration cytology (FNAC) is a proven diagnostic technique for establishing the benign or malignant character of breast lesions. Several cytological grading systems have been proposed for grading of carcinoma breast, with results similar to histologic grades. Aims: This study sought to evaluate the prognostic value of FNAC in invasive ductal carcinoma of breast by correlating it with histological grade. Settings and Design: Tertiary care hospital, retrospective analytical study...

Introduction: Cervicouterine cancer (CC) is a health problem worldwide and is the fourth most common cancer in women, with a greater proportion of individuals affected by advanced stages of the disease in developing countries. Objective: To determine the sensitivity and specificity of the TruScreen™ opto-electronic device vs. conventional cytology in CC screenings. Methodology: This is a prospective observational study that included individuals who presented for the first time at the Dysplasia Clinic of the Instituto Nacional de Cancerología from March 1 through April 30, 2016, and those referred due to abnormal conventional cytology...

Background: Squash cytology for intra operative diagnosis of central nervous system (CNS) tumors is an immensely important modality. Though its role in brain lesions is unquestionable and has been proven in a number of studies, its utility for spinal lesions is still a grey zone. Aims: To assess the diagnostic accuracy of squash preparation in spinal lesions and its statistical significance (sensitivity, specificity, positive predictive value, negative predictive value) following histological confirmation...

REVIEW
Dilip K Das
Synthesis and storage of thyroglobulin as well as synthesis of thyroid hormones and their release into the circulation are important functions of thyroid, which were studied in fine needle aspiration (FNA) smears from thyroid lesions. Evidence of thyroglobulin synthesis was demonstrated in neoplastic and nonneoplastic follicular cells, especially in Hürthle cells, in the form of colloid inclusions. Whereas the pinocytic vesicles containing colloid at the luminal end of in nonneoplastic and neoplastic follicular cells indicated engulfment of colloid for synthesis of thyroid hormones (T3 and T4 ), the marginal vacuoles (MVs) (fire-flare appearance) at the basal aspects of follicular cells suggested their release on way to the interfollicular capillaries...

Retinoblastoma is a rare malignant tumor of the retina usually seen in children before 5 years of age. The tumor is extremely rare in adults. We report here an unusual case of retinoblastoma in a 55-year-old adult female who presented to us with an orbital mass at a late stage of the disease. Detailed laboratory investigations and imaging studies could not make a precise diagnosis. The treating ophthalmologist suspected primary intraocular tumor, metastatic carcinoma, malignant melanoma, or lymphoma and referred the patient for fine needle aspiration cytology (FNAC)...
