Article Abstract
Background: Recently, the Indian Academy of Cytologists (IAC) has published the guidelines for interpretation and reporting of serous effusions. Till date, there are no studies on its applicability.
Aims: The present study was carried out to assess the feasibility of applying the IAC reporting categories to effusions, determine the frequency, and provide an estimate of the risk of malignancy (ROM) for individual diagnostic categories.
Materials And Methods: All cases of serous effusion fluids reported in the year 2019 were retrieved from the archives and reassigned as per the IAC diagnostic categories. The clinical and histopathological follow-up information was obtained wherever possible.
Results: A total of 1340 effusion samples were received from 1085 patients. There were 561 (51.7%) males and 524 (48.3%) females. Majority were pleural (1066, 79.5%), followed by peritoneal (187, 14%) and pericardial (87, 6.5%) effusions. The age ranged from 7 months to 92 years. There were 35 (2.6%) samples in category 1 (non-diagnostic), 954 (71.2%) in category 2 (benign), 17 (1.3%) in category 3 (atypical), 59 (4.4%) in category 4 (suspicious for malignancy) and 275 (20.5%) in category 5 (malignant). The estimated ROM in serous effusion samples was 20% for category 1, 16.7% for category 2, 50% for category 3, 94.4% for category 4 and 100% for category 5.
Conclusions: The categorization of serous effusion cytology samples as per the IAC diagnostic categories and as per the reporting format developed by the IAC is feasible and the management recommendations are mostly appropriate.

Background: commonly colonizes the genitourinary tract and primarily affects immunocompromised individuals. It is mostly confined to localized infections, with bloodstream dissemination being rare. Because of its fastidious nutritional requirements, the organism is seldom recovered by routine blood culture, and the absence of a cell wall renders it intrinsically resistant to many first-line antimicrobials.

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease; cardiac involvement is a recognized complication, with pericardial effusion being one of the most frequent manifestations. Here, we present a patient with massive pericardial effusion in a known SLE patient without hemodynamic instability, highlighting concepts of pericardial compliance and physiological adaptation in autoimmune disease. We present a case of a 33-year-old female with a known history of SLE who presented with progressively worsening pleuritic chest pain over three weeks.

Pseudo-Meigs syndrome is a rare clinical entity characterized by the triad of ascites, pleural effusion, and a benign pelvic tumor other than an ovarian fibroma. Although typically considered benign and reversible following tumor removal, the syndrome can result in severe life-threatening compromise if unrecognized or untreated. Unlike the classical Meigs syndrome, which has occasionally been associated with fatal outcomes, no deaths related to pseudo-Meigs syndrome due to benign tumors have been previously reported.

Background Aims: Cancers of many different tissue origins can metastasize to the pleura, a space with a unique immune environment that predisposes to aggressive tumor behavior and the development of effusions, an exudative leakage of serous fluid accompanied by an immune infiltrate. Effusions are drained therapeutically to relieve dyspnea, often several times per week. Characteristically, they contain 50-1000 × 10 viable pleural T cells (PITs), which can be reliably activated and expanded in culture, making them an ideal source for generation of a cellular therapeutic.

Compared to myelomatous effusions, there is a lack of studies that specifically address hematolymphoid plasmacytic effusions (HPEs). We conducted a retrospective review study over 15 years to investigate the prevalence, cytologic patterns, potential interpretation pitfalls, and clinical associations of HPEs. Serous effusion fluids in which plasmacytoid and plasma cells represented more than 10% of effusion cells were classified as HPEs.
