ABSTRACT

Background: Cytological examination of exfoliated cells is very challenging and of paramount importance for diagnosis, staging and prognosis as the finding of cancer cells in such a specimen denotes that the patient has advanced and incurable cancer. Aims & Objective: To study serous effusion for various pathological conditions. Material and Methods: The study was performed on serous effusions. Serous effusions from pleural, pericardial and peritoneal fluid were included and all other fluids were excluded. Their clinical history and other relevant parameters were noted. Collection was performed with 18-gauge needle under local anaesthesia and sterile conditions. When delay, samples were stored at 2-6 ͦC. Conventional smear and or Cytospin method were performed. Ether alcohol (wet fixed) and air dried smears were used. H & E stain, papanicolaou stain and MGG stain were done. Results: Out of total 355 cases, 186 were of pleural fluid, 164 of peritoneal fluid and 5 were of pericardial fluid. 288 cases were benign, 24 cases were malignant effusion, 17 cases were suspicious of malignancy and 26 cases were degenerated. Transudate, haemorrhagic and straw coloured fluid were more common. Conclusion: Benign effusions are common in younger whereas malignant effusions are common in older people. A combined approach to morphology by may-grunwald giemsa, papanicolaou with haematoxylin and eosin stain was better than individual method. Recurrent hemorrhagic effusions are more common in malignant effusions. Conventional smear method can yield good result. Scattered cells are indicative of benign effusions and clusters, 3 D balls, papillary patterns indicate malignant effusions.

ABSTRACT

Cystadenoma is an uncommon benign epithelial neoplasm. Cystadenoma usually occurs on the palatal and buccal mucosa, but is less commonly found in the retromolar regions.A 43-year-old male patient noticed a swelling on his gingiva distal to the right mandibular second molar. Physical examination showed a diffuse poorly circumscribed swelling extending from the lingual gingiva distal to the right mandibular second molar to the floor of the mouth and pharynx. The tumor size was 20 x 27 mm. The surface mucosa was purply-blue in parts. About 4 ml of pale yellow serous fluid was aspirated. The tumor was surrounded by a capsule and was excised successfully above the periosteum, incorporating a 2 mm safety margin including the surface mucosa. The tumor consisted of a fibrous capsule with multiple cystic cavities of various sizes. The cysts were lined by a layer of columnar epithelium, with intracystic papillary proliferation in some areas. No cytologic atypia or invasion of the surrounding tissues were observed.There is no evidence of recurrence ten years after excision, suggesting that complete excision is sufficient treatment in such cases.

ABSTRACT

PURPOSE: To evaluate the correlation between the degree of serous fluid and best corrected visual acuity at the first visit in central serous chorioretinopathy using optical coherence tomography. METHODS: Retrospective analysis was performed for 30 eyes of 30 patients with central serous chorioretinopathy. Cross-sectional retinal images through the center of the fovea were obtained from all eyes by optical coherence tomography. The height, sectional area, and the tangent of theta (tan theta) were estimated. They were statistically analyzed and correlated with best corrected visual acuity. RESULTS: Mean (+/-SD) height of serous fluid was 341.40+/-120.60 micrometer, mean (+/-SD) sectional area was 0.55+/-0.29 mm2, and mean (+/-SD) tan theta was 0.22+/-0.04. The correlation coefficients between best corrected visual acuity at the first visit and sectional area were r=-0.740 (P=0.001). CONCLUSIONS: Optical coherence tomography is useful for the quantitative evaluation of serous neurosensory retinal detachment and estimating visual acuity in central serous chorioretinopathy.

ABSTRACT

Objective To enhance the diagnosis rate for metastasis adenocarcinoma cells in serous fluids and detect a panel of a monoclonal antibodies for distinguishing adenocarcinoma cells from reactive mesothelial cells in serous fluids. Methods Three marks of low molecular weight cytokeratin (CK LMW ), carcinoembryonic antigens (CEA) and mesothelial cells (MC) were used to immunostain the cells in serous fluids from 50 patients and in peritoneal washing from 14 patients. Results Expression rate of three groups of cells positive from CK LMW , CEA and MC in adenocarcinoma cells was 95.83%, 70.83%, 16.67%, in suspicious cancer cells 100%, 50.00%, negative, in reactive mesothelial cells 33.33%, 33.33%, 66.66%. The four suspicious cases and two reactive cases in primary cytopathological classifiecation should be reclassified as adenocarcinoma cases. The sensitivity, specificity and reliability of CK LMW , CEA and MC were 96.30%, 80.00%, 77.10%; 70.37%, 90 00%, 61 60%; 90.00%, 85.20%, 75.30%, respectively. Conclusion Immunocytochemistry, using a panel of CK LMW , CEA and MC antibodies appears to be adjunct of important value for distinguishing adenocarcinoma cells from reactive mesothelial cells in serous fluids.
