Background: Mediastinal tumors are an uncommon abnormalities found in clinical practice. Anterior mediastinum is the common site and tissue diagnoses of anterior mediastinal masses (AMMs) are very important for correct therapeutic decision.
Objective: We evaluate the different malignant AMMs in various age groups and the sensitivity of fine needle aspiration cytology (FNAC) and core needle biopsy (CNB). Cytology smears are reviewed with particular emphasis on pitfalls in the cytological diagnosis.
Materials And Methods: This was a prospective study of 50 patients who were consulted for AMMs and underwent FNAC and CNB under guidance of ultrasound or computed tomography (CT) scan from 2006 to 2011. Cytology smears and histological sections were evaluated in all patients.
Results: Among 50 cases, 36 were male and 14 were female. Most AMMs (52%) were identified in the fifth and sixth decades of life. Metastatic carcinoma and nonHodgkin's lymphoma are the common AMMs. Adequate tissue material was obtained in 49 of 50 cases by CNB. Of these 49 patients, 35 (71.42%) cases were diagnosed correctly by FNAC, whereas 14 (28.57%) cases were not diagnosed definitely by FNAC. The sensitivity of CNB for AMMs was 97.95%, significantly higher than FNAC (71.42%) (P < 0.05). CNB had statistically significant higher diagnostic rate than FNAC in the noncarcinoma group (100% versus 62.96%) (P < 0.05). There is no significant difference of CNB and FNAC in carcinoma group (P > 0.05). Diagnostic rate of FNAC was higher for carcinomatous lesions (81.81%) than for noncarcinomatous lesions (62.96%).
Conclusion: Ultrasound or CT scan-guided CNB in combination with FNAC are safe, minimally invasive, and cost-effective procedure, which can provide a precise diagnosis in the AMMs, and may obviate the need for invasive surgical approach. FNAC usually suffice for carcinomatous lesions but CNB should be performed whenever the diagnosis of carcinoma is equivocal or noncarcinoma lesions are suspected.

Background And Aims: Benign lesions, inflammation, cysts and pseudocysts, as well as neoplasms of the exocrine and endocrine parts of the pancreas can be easily identified using cytological methods. The sensitivity and specificity can be increased with the help of additional examination methods. The sensitivity of intraoperative rapid cytology reaches about 99%.

Objectives: The global prevalence of Hashimoto's thyroiditis (HT) and differentiated thyroid cancer (DTC), particularly papillary thyroid cancer (PTC), is increasing. However, studies assessing correlations between these diseases have yielded inconsistent findings. Furthermore, patients diagnosed with HT show a higher prevalence of indeterminate cytology than those without HT.

Purpose: Ultrasound-guided fine-needle aspiration cytology (FNAC) is a widely used diagnostic procedure which facilitates the differentiation of salivary gland lesions. Although the performance of salivary gland FNAC (SG-FNAC) has improved since the introduction of the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC), the range of the reported performance is still wide. Therefore, the aim of this study was to determine lesion- and sampling-related factors that influence the success of SG-FNAC.

Introduction: Lipomas are benign tumors primarily composed of adipose tissue, typically found in subcutaneous or intramuscular sites across the body. While lipomas in the hand are uncommon, their occurrence in both thenar and hypothenar eminences is exceedingly rare.
Case Presentation: In this case, 65-year-old female admitted to hospital with a ten-year history of progressive swelling in the palmar aspect of her right hand, resulting in limited finger movement.

Cytopathology is a cost-effective diagnostic method crucial for investigating suspected neoplastic lesions, particularly in Nigeria's healthcare system, where non-communicable diseases, especially with increasing rates of cancer. This review highlights the evolution of cytopathology practice in Nigeria, detailing its historical development, current methodologies, and the challenges faced within the healthcare framework. Despite advancements in diagnostic techniques such as immunocytochemistry and molecular diagnostics globally, conventional methods remain essential due to their affordability and accessibility.
