RESUMO

Background: Endometrial aspiration (EA) is an economic, painless technique on an outpatient basis. Present study aimed at cytological evaluation of EA for (a) cellular yield and morphology and (b) utility of cell block (CB) and cytocentrifuge (CC) techniques. Materials and Methods: EA samples were divided into two aliquots. Colorless samples were processed (1000 rpm × 6 min) for conventional smear (CS) and CC, both stained by Papanicolaou. Hemorrhagic samples were processed for CS and CB (paraffin embedding, hematoxylin-eosin stain). Results: Endometrial aspirates from January 2021 to January 2022 were included. Indications comprised abnormal uterine bleeding (AUB; 87), prolapse (eight), and infertility (two). Among 77 hemorrhagic aspirates, the yield was 85.7% by CS and 90.9% by CB. Among 20 colorless aspirates, the yield was 55% by CS and 65% by CC. The yield was 85.7%, 84.4%, and 83.3% with endometrial thickness 1-5, 6-10, and 11-15 mm, respectively. The yield was 83.9%, 50%, and 0% in AUB, prolapse, and infertility, respectively. CS morphology showed the categories of benign (93.5%) and atypia (6.5%). All cases with benign morphology correlated with CB and CC. CB offered architectural evaluation, while CC had a shorter turnaround time. Conclusion: Focusing on menorrhagia cases in secretory phase, nondilution of EA samples, and simultaneous endometrial biopsy can enhance cytology evaluation. In an era where "less should convey more," EA shows potential as a screening technique vis-à-vis invasive "dilatation-curettage" technique.

RESUMO

CONTEXT: An audit aims to verify conformance to required processes, assess their implementation, and define the targets of quality control. AIMS: To evaluate preanalytic and analytic phases of surgical histopathology in a tertiary healthcare center. SETTING AND DESIGN: An observational retrospective and prospective study over 3 months each of year 2013 and 2014. MATERIALS AND METHODS: Biopsy, small resections, large organ resections, bone marrow aspirate/biopsy (BMA/BMB), and frozen section samples received in surgical histopathology were categorized as I to V, respectively. A manual audit was done for preanalytical phase (adequacy of clinical information and grossing adequacy) and analytical phase [turnaround time (TAT) and tissue section quality]. STATISTICAL ANALYSIS: Qualitative data was assessed by Chi-Square test. Quantitative data was assessed using One-Way Analysis of Variance. RESULTS: Among 3179 total cases, category I to V had 1558 (49%), 1099 (34.6%), 342 (10.8%), 124 (3.8%), and 56 (1.8%) cases, respectively. Category I had shortest TAT but maximum number of inadequately sent specimens and recuts. Category III had maximum cases with inadequate clinical history, grossing errors, additional sections, and longest TAT. Category IV had maximum cases with poor quality sections. Category V had maximum cases with inadequate demographic details and clinical investigations. BMB (114, 91.9%) was more useful than BMA for diagnosis. Mean TAT for fixed tissues and frozen tissues was 3.6 ± 1.8 days and 26.6 ± 11.2 min, respectively. CONCLUSIONS: Total 25% of annual workload was studied by an observational, manual audit. Quality indicators were achieved as per international norms despite limited resources. Remedial actions were suggested for technicians, clinicians, and pathologists to minimize errors.

RESUMO

Coexistence of multifocal neural crest tumors, namely meningioma, melanoma, and nerve sheath tumors, is termed as neurocristopathy. Neurofibromatosis is the commonest form of neurocristopathy. We report a rare case of frontal lobe metastatic melanoma coexistent with a parietal lobe meningioma, in the absence of any stigmata of neurofibromatosis.

RESUMO

Sclerosing extramedullary hematopoietic tumors (SEMHTs) are associated with chronic myeloproliferative neoplasms. These extremely rare mass lesions were first described in kidney and peritoneum. On histopathology, they are characterized by sclerosis, entrapped fat, atypical megakaryocytes with myeloid and erythroid elements. Only approximately ten cases have been subsequently reported in orbit, lacrimal system, liver, omentum, and skin. The authors present a case of SEMHTs as incidentally detected omental nodules, while the patient was undergoing splenectomy for Janus kinase-2 negative myelofibrosis. The authors postulate their origin in omentum-associated lymphoid tissue; and highlight the diagnostic dilemma presented by SEMHTs at frozen section.

RESUMO

BACKGROUND: Rheumatic heart disease is an important cause of valvular disease in India, with resultant alterations in the interatrial septum and fossa ovalis. Morphometric details of fossa ovalis may help in its localization during transseptal catheterization so as to prevent complications. METHODS AND RESULTS: Autopsy heart specimens of rheumatic heart disease (n=30) and non-cardiac death (n=30) patients between 15-45 years of age were studied as case and control group, respectively. The dimensions of fossa ovalis and interatrial septum were measured. The ratio of area of fossa ovalis to septum was calculated. Case group showed a significant increase in surface area of septum and fossa as compared to control group. The septal area was significantly increased in 15-30 years and 31-45 years groups, specially females in the former group. The fossa area was increased only in 31-45 years age group. The ratio of area of fossa to septum was not statistically altered in cases versus controls. Case group, specially females of 15-30 years, showed a significant horizontal orientation of fossa as compared to controls. Cases having both mitral and aortic stenosis showed highest increase in the areas of fossa and septum, as also the most horizontal orientation of fossa. CONCLUSIONS: The enlargement of the septal area begins at an early age in rheumatic heart disease along with initial hemodynamic and valvular alterations. There is a categorical horizontal orientation of fossa ovalis in these cases. Varying dynamics in stenotic and regurgitant valves leads to varying morphological changes in dimensions of fossa ovalis and septum.
