Abruptio placenta can be a catastrophic event with a high association with adverse maternal and fetal outcomes. We present a case of massive abruptio placenta occurring in a young asymptomatic mother at 30 weeks\' gestation. Although electronic fetal monitoring and ultrasound allowed a prompt diagnosis of an 8 × 5 cm retroplacental hematoma, the fetus died at the time of emergency cesarean section. The fetus was intubated, but could not be resuscitated. Histologic examination of the placenta documented thinning and stacked hypercapillarized villi, with syncytial buds and foci of fibrinoid necrosis in the presence of hyaline streaks on both the maternal and fetal sides.

This case report presents a 64-year-old male with a giant intramuscular lipoma on the right lumbar region\'s latissimus dorsi muscle. The patient presented with painless swelling, which gradually increased over six years. Magnetic resonance imaging (MRI) confirmed the presence of the lipoma, prompting surgical intervention. The surgical procedure involved meticulous dissection and complete excision of the tumor. Histopathological examination validated the diagnosis. Comparative analyses with similar cases highlighted variations in surgical approaches and the challenges in managing intramuscular lipomas. This case emphasizes the importance of considering intramuscular lipomas in soft tissue mass differentials and the significance of comprehensive management strategies for optimal patient outcomes.

Lipomas are common benign soft tissue tumors, typically presenting as painless, slow-growing masses of mature adipose tissue. However, their occurrence as pedunculated lesions in the perianal region is rare. We present a case of a 70-year-old male with a 20-year history of a painless, cosmetically concerning mass in the perianal region. Clinical examination and ultrasonographic findings were consistent with a pedunculated lipoma. Surgical excision was performed successfully, and histopathological examination confirmed the diagnosis of lipofibroma. This case highlights the importance of considering unusual presentations of lipomas in the differential diagnosis of perianal masses. It emphasizes the role of surgical excision for symptomatic or cosmetically concerning lesions. Long-term follow-up is essential to monitor for recurrence and ensure optimal patient outcomes.

Endometrial adenocarcinoma is a prevalent malignancy among postmenopausal women, often presenting with symptoms such as abnormal vaginal bleeding and pelvic pain. We present a case of a 60-year-old postmenopausal female who exhibited abnormal vaginal bleeding for three months, accompanied by pelvic pain and unintentional weight loss. Clinical evaluation, including physical examination, imaging studies, and histopathological examination, led to the diagnosis of well-differentiated endometrial adenocarcinoma. The patient underwent an abdominal hysterectomy with bilateral salpingo-oophorectomy, and histopathological analysis confirmed invasive tumor involvement in the lower uterine segment and cervix. The final pathological tumor, node, and metastasis (TNM) staging was reported as pT1b No Mx, FIGO (International Federation of Gynecology and Obstetrics) stage II. This case underscores the importance of considering endometrial adenocarcinoma in the differential diagnosis of postmenopausal bleeding and highlights the significance of timely diagnosis and multidisciplinary management for optimizing patient outcomes.

UNASSIGNED: The preoperative differentiation of benign form malignant cervical lymphadenopathy (CLA) is crucial in determining the need for surgical intervention. This study aims to assess the diagnostic performance of ultrasonography (US), fine-needle aspiration cytology (FNAC), and their combination with the postoperative histopathological diagnoses of CLA.
UNASSIGNED: In a retrospective study between April 2021 and May 2023, 214 patients with CLA were assessed with preoperative US and FNAC. The morphological parameters, including tissue margins, vascularity, and fatty hilum echogenicity, were collected and analyzed retrospectively. The diagnostic efficacies of US, FNAC, and their combined use were compared to the postoperative histopathological findings.
UNASSIGNED: In the final histopathological examination, 185 cases (86.4%) were found to be benign, while 29 cases (13.6%) were determined to be malignant. The US features of fatty hilum, echogenicity, and vascularity pattern had the highest diagnostic accuracy in characterizing CLA patterns, with values of 88.3%, 85.5%, and 85.0%, respectively. The receiver operating characteristic (ROC) curve showed a significantly higher area under the curve (AUC) value of 0.883 (95% CI: 0.832-0.923; P<0.0001) for the combined use of all US parameters with better sensitivity (93.10%) and specificity (68.65%) than individual parameters. The overall sensitivity, specificity, and accuracy of FNAC were 97.3%, 82.8%, and 95.3%, respectively. Additionally, US parameters and FNAC together showed a significantly higher AUC value of 0.924 (95% CI: 0.880-0.956; P<0.0001) and achieved a sensitivity of 86.21% and specificity of 88.65%.
UNASSIGNED: The combined use of US and FNAC provides high sensitivity, specificity, and diagnostic accuracy in characterizing CLA patterns. In limited-resources settings, this approach is feasible, less invasive, and cost-effective, thereby enabling clear management strategies and avoiding additional surgical interventions.

BACKGROUND: Mechanical thrombectomy has emerged as the primary endovascular treatment for acute ischemic stroke. Numerous studies have investigated the relationship between thrombus composition and factors such as pharmacological thrombolysis, stroke etiology, mechanical thrombectomy, and radiological imaging. However, limited research has explored the association between thrombus composition and clinical outcomes.
METHODS: This retrospective analysis examined the histopathological examination of thrombi retrieved from 50 patients with acute ischemic stroke between May 2020 and May 2023. The composition of the retrieved thrombi was assessed using HE staining to quantify the proportions of red blood cells, white blood cells, platelets, and fibrin. Based on the predominant composition of the thrombus, the patients were divided into two groups: erythrocyte-rich and fibrin-rich. Demographics, clinical characteristics, and clinical outcomes assessed by the National Institutes of Health Stroke Scale (NIHSS) score and modified Rankin Scale (mRS) scores were collected retrospectively.
RESULTS: Of the 50 patients, 23 were classified in the erythrocyte-rich group, and 27 were classified in the fibrin-rich group. There were no significant differences between the two groups in terms of age, sex, stroke subtype, history of hypertension and diabetes, thrombus location, NIHSS scores, mRS scores on admission, the time interval from symptom onset to hospitalization and reperfusion, or the rate of successful reperfusion. However, erythrocyte-rich thrombi were associated with a shorter time interval from puncture to reperfusion. No significant differences were found in the red blood cell fraction and fibrin/platelet fraction between large artery atherosclerosis and cardioembolism. At the 90-day follow-up, patients with erythrocyte-rich thrombi exhibited lower NIHSS scores and more favorable functional outcomes (mRS scores of 0-2) compared to those with fibrin-rich thrombi.
CONCLUSIONS: Erythrocyte-rich thrombi were linked to shorter time intervals from puncture to reperfusion and favorable clinical outcomes in patients with acute ischemic stroke. The composition of the thrombus may influence the thrombectomy strategy for endovascular therapy.

BACKGROUND: Cardiac hemangiomas are very uncommon benign primary tumors. They are usually located preferentially in the right atrium and their location in the interatrial septum is extremely rare.
METHODS: We report the case of a 41-year-old patient who was admitted due to a stroke. The transthoracic echocardiogram revealed a large mass in the right atrium adhered to the interatrial septum. Suspecting an atrial myxoma, surgical intervention was performed confirming that the mass extended within the thickness of the interatrial septum, protruding into the right atrial cavity. The histologic report confirmed a hemangioma.
CONCLUSIONS: Cardiac hemangiomas are rare primary tumors and are usually misdiagnosed as other cardiac tumors. Histopathological examination is essential for a definitive diagnosis.

UNASSIGNED: Lymphovascular invasion (LVI) is a pivotal histopathological parameter in prostate cancer (PCa), holding significant prognostic implications. Our study pursued a dual objective: firstly, to identify preoperative factors associated with LVI, aiming to unveil markers facilitating the recognition of patients prone to LVI during postoperative examination; and secondly, to assess postoperative outcomes correlated with LVI.
UNASSIGNED: We retrospectively analyzed 861 nonmetastatic PCa patients who underwent radical prostatectomy (RP), investigating preoperative factors and postoperative outcomes. Surgical specimens were processed following established guidelines. Statistical analyses utilized non-parametric tests to assess the association between LVI and both pre- and postoperative factors. Furthermore, logistic regression analyses were utilized to develop models aimed at identifying the most significant predictors of LVI and pN1 status, respectively.
UNASSIGNED: Numerous preoperative factors exhibited significant correlations with LVI, offering valuable clinical insights. Logistic regression identified magnetic resonance imaging (MRI)-based clinical tumor stage (cT) 3-4, biopsy Gleason Grading Group (GGG) 3-5, preoperative prostate specific antigen (PSA) ≥20 and percentage of positive biopsy cores (PPBC) ≥50% as the strongest preoperative predictors of LVI. Additionally, the study uncovered an association between LVI and postoperative outcomes, including postoperative PSA (p value <0.001), extracapsular extension (ECE) (<0.001), positive surgical margins (PSM) (<0.001), perineural invasion (PNI) (<0.001), pathological tumor stage (pT) (<0.001), pathological lymph node status (pN) (<0.001), postoperative GGG (<0.001), and operative time (0.023). Notably, the study revealed a novel and substantial association between LVI and an increased number of positive lymph nodes in pN+ patients in the univariate analysis (<0.001). Furthermore, we have found an association between LVI and pN1 status in the logistic regression analysis (odds ratio [OR] = 23.905; p <0.001).
UNASSIGNED: Our findings underscore the pivotal role of LVI in influencing the prognosis of prostate cancer (PCa). The study acknowledges the challenges associated with preoperative LVI assessment and emphasizes the need for future research to unravel the factors associated with this histopathological finding. Significantly, our research stands out as the first, to the best of our knowledge, to reveal the association between LVI and the number of positive lymph nodes in pN+ patients.

Background The incidence of head and neck carcinoma is increasing. The use of an intraoperative frozen section plays a vital role in the evaluation of margin status in patients undergoing surgery for oral squamous cell carcinoma. A negative margin is not only an indication of successful surgery but also decreases the recurrence of disease and improves the overall survival of patients. Aims and objective The aim of this study is to assess the accuracy of margin in patients undergoing surgery for oral squamous cell carcinoma by intraoperative frozen section and compare it with conventional histopathological examination. Methodology The approach of our study was a hospital-based prospective study conducted on 28 patients diagnosed with oral squamous cell carcinoma. A frozen section was done on all patients undergoing surgery and compared with histopathological examination. Results Out of 28 patients undergoing surgery, the incidence of males was more than females, with a ratio of 6:1. The most common site of the tumor was left buccal mucosa comprising 28.57%, followed by gingivobuccal sulcus comprising 17.85%. In our study, the frozen assessed margin showed a sensitivity of 58.33%, specificity of 98.76%, and accuracy of 95.25%. Conclusion Frozen section is a reliable method for confirmation of margin accuracy and thus reduces the chance of re-surgery and recurrence of disease and increases overall patient survival.

UNASSIGNED: Ganglioneuroma is a rare benign neuroblastic tumor originating from sympathetic ganglion cells in the peripheral nervous system. It is often incidentally discovered during imaging studies and primarily affects children and young adults.
METHODS: We present a case report of a 21-year-old female diagnosed with non-Hodgkin lymphoma who had an abdominal mass incidentally detected during imaging, Initially mistaken for lymphoma in the setting of the primary diagnose. After the chemotherapy for the lymphoma, the mass did not response to the treatment, so the mass was surgically excised, and histopathological examination confirmed the diagnosis of ganglioneuroma. The patient responded well to treatment for lymphoma and remains in good condition without signs of recurrence.
UNASSIGNED: To the best of our knowledge, this is the first case that describes an association between an intraabdominal ganglioneuroma and non-Hodgkin\'s lymphoma.
CONCLUSIONS: This case highlights the importance of considering ganglioneuroma as a differential diagnosis when evaluating abdominal masses in patients with lymphoma.
