BACKGROUND: Kaposi’s sarcoma (KS) is a vascular malignant tumor characterizedby human herpesvirus 8 infection of neoplastic cells. Diffuse cutaneous lesions represent theclassical clinical presentation. (more…)
OBJECTIVES: To characterize the cytopathologic outcome of lesions detected onpositron emission tomography (PET) scan. STUDY DESIGN: Cases with fine needle aspiration (FNA)performed because of a PET-positive lesion over an 18-month period were reviewed. Correlation withthe standard uptake value (SUV) (more…)
BACKGROUND: Erythema nodosum leprosum (ENL), the type 2 lepra reactionoccurring in lepromatous or borderline lepromatous leprosy, presents clinically with acutemanifestations that compel the patient to seek medical attention. Recognition and timely managementof these patients is critical in order to avoid permanent disability. Fine needle aspirationcytology (FNAC) is a simple, effective tool that aids in correct diagnosis and management of ENL.CASE: (more…)
OBJECTIVE: To study the role of fine needle aspiration cytology (FNAC) in thediagnosis of bone tumors and its impact on therapeutic decisions. STUDY DESIGN: A group of 122cases of bone tumor were evaluated by FNAC. Detailed diagnoses were compared with the availablehistology. RESULTS: Diagnostic accuracy of FNAC was 90.5% in this study. (more…)
OBJECTIVE: To compare the cytologic findings and diagnoses of breast fineneedle aspiration (FNA) samples of well-defined lesions (WDL) with those of poorly defined induratedlesions. STUDY DESIGN: We examined 371 consecutive breast FNA specimens obtained without diagnosticimage guidance. (more…)
OBJECTIVE: To formulate cytologic features for differential diagnosis ofbasal cell adenoma (BCA). STUDY DESIGN: The usefulness of 5 items for a cytologically definitivediagnosis of BCA was examined. The 5 items in 8 BCA and 22 non-BCA cases (adenoid cystic carcinoma[ADCC], basal cell adenocarcinoma, myoepithelioma, pleomorphic adenoma and polymorphous low-gradeadenocarcinoma) that displayed mimicking cytology were examined cytologically. RESULTS: The usefulitems were (more…)
BACKGROUND: Cystic neoplasms of the pancreas comprise a pathologically heterogeneous group of lesions that usually present with similar, nonspecific clinical features. Based on the diagnosis, treatment varies from watchful observation of the lesion to total surgical resection of the pancreas. (more…)
BACKGROUND: Malignant pleural effusion in association with mesothelioma, bronchogenic carcinoma and breast carcinoma is common, although less frequently reported with other malignancies. We report a follicular variant of papillary thyroid carcinoma (FVPTC), diagnosed on fine needle aspiration cytology (FNAC) of thyroid and lymph nodes and subsequently proved to have metastasized to the pleural cavity. CASE: A 46-year-old man presented with history of breathlessness, thyroid swelling, pleural effusion and bilateral cervical lymphadenopathy. FNAC of the thyroid swelling and the lymph nodes showed features of FVPTC with cervical lymph node metastasis. (more…)
