Fine needle aspiration (FNA) plays a significant role in the diagnosis of thyroid lesions due to its simplicity and low cost. Hashimoto's thyroiditis (HT) is the second most common thyroid lesion next to endemic goitre diagnosed on FNA in iodine (I2) deficient areas. Data on its incidence, prevalence and clinicopathological features in I2 deficient areas is scanty compared to I2 sufficient areas. In the present study the patients presented with HT a decade earlier than reported in I2 sufficient areas. Presentation as a nodular thyroid is common. Diagnosis of HT is likely to be missed in smears showing cytological evidence of hyperplasia or abundant colloid. HT was concurrent in 20 cases of endemic goitre. Careful screening for Hurthle cell change and lymphocytic infiltration into follicular cells should be carried out. In equivocal cases multiple punctures and immunological investigations are helpful. In antibody-negative cases repeat FNA at follow-up is useful. Marked lymphocytic infiltration and Hurthle cell change may indicate a hypothyroid state but hormonal levels are required for clinical management.
Sixty symptomatic confirmed human immunodeficiency virus (HIV)-positive adult patients, of both sexes, suspected of having a fungal infection were taken as a study population, and the clinicomycological profile was correlated with the immunological status of the patients with particular reference to CD4 counts. Relevant samples were collected and subjected to direct microscopy, fungal culture and serology. CD4 counts were determined by flow cytometry. Patients belonged to the age group of 17-65 years, with a male : female ratio of 4.8 : 1. Heterosexuality was the commonest mode of transmission. Candidiasis was the most common diagnosis (41.7 %), followed by cryptococcosis (10.0 %), and pneumocystinosis and aspergillosis (8.3 % each). Two cases of histoplasmosis were also diagnosed. A low mean CD4 count of ,200 cells ml Various fungal infections correlated well with the mean CD4 counts. It was difficult to correlate statistically WHO and CDC staging because of the small sample size. However, it was possible to assess to a limited extent the possibility of using clinical diagnosis to predict the status of progression of HIV infection in a resource-poor outpatient setting.
Background:Epidermal inclusion cyst in the breast (EICB) is very rare. It presents as breast lump mainly in peri-areolar region and needs to be differentiated from other breast lesions with predominance of squamous cells.Aim:To analyze the role of fine needle aspiration cytology (FNAC) in patients presenting with breast lump.Materials and Methods:The present study is a retrospective study over the period of past 2 years, where the patients presented with firm breast lumps. Six of these cases were diagnosed as EICB on FNAC. Smears from these cases were reviewed for cytomorphological findings and correlated with clinico-radiological details.Results:Patients ranged in age from 25 to 60 years, and female to male sex ratio was 2:1 (female 4, male 2). Mammography was done in women (4), which showed solid, well-defined mass lesions in peri-areolar region and were suggestive of benign breast lesions (3) and infective lesion (1). FNA was performed; Giemsa-stained smears showed predominantly mature benign squamous cell and anucleated squames in all cases, thus one of the cytological diagnoses was EICB. Five of these cases had histological confirmation.Conclusion:EIC of breast is not that rare lesion as considered. The patients may not seek medical attention because of small painless swelling; unless the lump increases in size or becomes painful. FNAC is confirmatory in the presence of a typical pultaceous aspirate and cytomorphological features of EIC. Thus, FNAC plays a crucial role in its diagnosis and management. Symptomatic cases should be readily excised and need histological correlation to rule out any potential complications that can arise in these cysts.
Cytology is a useful tool to detect malignant effusions. However, in uncommon malignancies presenting as effusions, a detailed clinical history and ancillary investigations are often required to make a correct diagnosis.
The present study aimed to investigate pulmonary function tests (PFTs) in children with thalassemia and to assess the relation between the degree respiratory impairment with the body iron status. High resolution computed tomography of chest (CHRCT) and bronchoalveolar lavage (BAL) was performed to study the cause of pulmonary dysfunction. Thirty-one children with thalassemia over 8 years were included. PFTs were studied including lung volumes and carbon monoxide diffusion capacity (DLco). Patients with abnormal PFTs and/or impaired DLco were further subjected to CHRCT and BAL. Total cell count was measured; differential count was performed on Giemsa and PAP smears. Iron laden macrophages were identified on Perl's stain. PFTs were normal in 51.61%, diffusion capacity impaired in 41.16%, restriction in 16.12%, while obstruction in 3.22% of cases, respectively. There was significant inverse correlation between DLco and serum ferritin. Through multivariate regression analysis, ferritin was found to be a strong predictor for forced vital capacity and total lung capacity. Bronchial dilatation and areas of air trapping were the predominant CHRCT findings. Iron laden macrophages were demonstrated in 14 of 15 patients in BAL. A significant correlation between serum ferritin and DLco, forced vital capacity, total lung capacity, and the presence of iron laden macrophages in BAL indicates that iron plays a major role in the etiopathogenesis of these abnormalities.
Oral mucosa is a rare site for cysticercosis. This paper describes eight cases of cysticercosis involving the oral cavity: four in the buccal mucosa, two in the lips, one in the tongue and one in the gums. All of the patients presented with a solitary superficial mucosal nodule, with duration varying from one month to three years. Larval fragments of cysticercus cellulosae on an inflammatory background were seen in cytologic smears in all cases. Diagnosis of cysticercosis was clinically unsuspected in all these cases prior to aspiration cytologic diagnosis.
