ABSTRACT
Objective: During routine fine needle aspiration cytodiagnosis of papillary thyroid carcinoma (PTC), a number of cases are diagnosed as suspicious; or it is suggested that PTC or a neoplasm be ruled out by histopathology. Since these diagnostic labels are likely to put the clinicians in a difficult situation while planning the management, this study aims to find out how much the surgeon should read from these reports. Materials and Methods: The patients were divided into two groups. Group A included 38 cases diagnosed as PTC or suspicious of PTC. Group B included 40 cases in which it was suggested that PTC/a neoplasm to be ruled out and non-neoplastic lesions with one or more cytologic features of PTC. The two groups were compared with clinical, imaging and cytomorphologic features. Results: A significant difference was observed with respect to age between Group A and Group B (P<0.001). The frequency of the following five cytologic features was significantly higher in Group A: papillary formation (P<0.001), psammoma bodies (P=0.054), fine nuclear chromatin (P=0.010), frequent nuclear grooves (P<0.001) and intra-nuclear cytoplasmic inclusion (P<0.001). Three or more of the five cytologic features were also reported in significantly higher number of Group A cases (P<0.001). Majority (81.8%) of the cases with subsequent histology in Group A were confirmed as PTC as opposed to 7.7% in Group B (P<0.001). Conclusions: Thus, cases with definitive cytodiagnosis of PTC and suggestive of PTC (Group A) should be taken much more seriously by the surgeons as compared to Group B cases.
ABSTRACT
Abdominal tuberculosis is endemic in most developing countries, and its incidence in western countries has risen because of the acquired immunodeficiency syndrome (AIDS). The disease can be a diagnostic challenge even for experienced physicians because patients with the disease usually present non specific symptoms signs. It can mimic conditions as varied as lymphoma, Crohn's disease, amebiasis, and adenocaricoma. Imaging features are not pathognomonic but can readily suggest the diagnosis when considered along with the clinical presentation, immune status, and demographic background of the patient. In this review we highlight the important features of this disease as shown by various imaging modalities
La tuberculosis abdominal es endémica en la mayoría de los países en vías de desarrollo y su incidencia en los países occidentales aumentó debido a la incidencia del síndrome de inmunodeficiencia adquirida (sida). Esta enfermedad puede ser un desafío diagnóstico, incluso para los médicos con experiencia, porque los pacientes habitualmente presentan signos y síntomas inespecíficos. Puede asemejarse a patologías tan variadas como el linfoma, enfermedad de Crohn, amebiosis y adenocarcinoma. Las características de las imágenes no son patognomónicas, pero pueden sugerir el diagnóstico cuando se las considera junto con la presentación clínica, el estado inmunológico y las características demográficas del paciente. En esta revisión analizamos las características importantes de la enfermedad mediante las distintas modalidades del diagnóstico por imágenes
