Unusual Finding

Cardiac fibromas are benign primary tumors composed of connective tissue and fibroblasts. These uncommon tumors are primarily found in the pediatric population, and their prevalence among the adult population is exceedingly rare. We report a case of an adult with nonspecific symptoms, who was subsequently found to have a solitary mass located in the left ventricle. This case highlights an unusual finding in an adult who through various imaging modalities, surgical excision, and immunohistological analysis was found to have a cardiac fibroma.

Tissue Origin

ABSTRACTMyoepithelial carcinomas of soft tissue origin are rare tumors in the pediatric population. Due to the rarity of this malignancy, very few cases have been reported in the literature, and a consensus on treatment has not been established. Most myoepithelial carcinomas of soft tissue present in the extremities and are treated with surgical excision followed by adjuvant radiotherapy. We report 2 cases of pediatric myoepithelial carcinoma presenting with vertebral involvement making complete surgical removal impossible. These patients underwent chemotherapy and adjuvant radiotherapy as the main treatment for their primary tumors.

11025 Background: In Children’s Oncology Group trial AEWS0031, VAC alternating with IE administered every 2 weeks rather than every 3 weeks resulted in a superior event-free survival (EFS). In the 2-week dosing group, a median interval of 15 days (mean 17.3) was achieved. Only 12% of patients enrolled in the trial were age 18+ and thus the feasibility of interval-compressed VAC/IE in the adult population remains poorly described. We conducted a retrospective analysis of our institutional experience using this regimen. Methods: Pharmacy administration records at Oregon Health and Science University were reviewed to identify patients age 18+ with Ewing and Ewing-like sarcoma who received VAC/IE q2wk, with first dose between January 2011 and March 2018. Results: 24 patients were identified. Median age was 28 (range 18 to 60). At diagnosis, 67% had localized disease. The most common primary sites were extremity (38%) and pelvis (17%); another 25% had extra-osseous primary tumors. Local therapy included surgery in 50% and XRT in 33% of subjects. The median interval between cycles was 16.7 days (mean 17.5). The median number of admissions for toxicity per patient was 2. The median number of dose delays (toxicity prolonging the 2 week interval) per patient was 4. Early treatment discontinuation occurred in 17%. Cumulative doses are outlined in Table. 5-year overall survival was 41%. 5-year EFS was 52% among patients with localized disease and 0% among those with metastatic disease. Conclusions: For adults with Ewing and Ewing-like sarcoma, chemotherapy administered every 2 weeks is a feasible and effective therapy, without significant dose reductions required. Our results are comparable to prior studies involving a primarily pediatric population. [Table: see text]

Kaposiform Hemangioendothelioma

Abstract Background Kaposiform Hemangioendothelioma (KHE) is a rare vascular tumor of intermediate malignant potential which shows locally aggressive growth but only rarely metastasizes. It is mostly considered to be a tumor of pediatric population but its occurrence in the adults is not uncommon as once considered. Histologically, KHE can mimic other soft tissue neoplasms of different behaviors (e.g. Kaposi Sarcoma, hemangioma) and establishing the correct diagnosis is important for appropriate treatment. Herein, we describe the clinicopathological features of 8 cases of KHE which will be helpful in making their diagnosis. Methods We reviewed pathology reports, microscopy glass slides and obtained follow up information about 8 cases of KHE which were diagnosed at our institution from January 2008 till June 2020. Immunohistochemical stain for HHV8 was also performed. Results Age ranged from 7 months to 25 years. Seven patients were less than 20 years of age and one patient was 25 years old. Equal gender distribution was observed. Extremities were the most common sites of involvement, followed by head and neck, pancreas and ischiorectal region. 2 cases were resection specimen and all others were incisional biopsies. The largest tumor size was 5.5 cm in one of the resections. The incisional/fragmented tissues were all less than 5 cm in aggregate. Most cases showed predominance of nodular growth and a minor component of spindle cell population along with lymphangiomatosis like vascular channels, with evidence of microthrombi in 2 cases. Few multinucleated giant cells were observed in 2 cases. None of the cases exhibited significant nuclear atypia or mitotic activity. One of the cases arising in dermis showed underlying bone involvement. HHV8 was negative in 7/7 cases. Conclusions KHE can also involve adult population and it should always be considered in the differential diagnoses of a vascular lesion. Presence of multinucleated giant cells is a rare finding. Knowledge about histological features and potential mimics is helpful in avoiding misdiagnosis.

Abstract Background Head and neck is a relatively common site of occurrence for the peripheral nerve sheath tumors, and majority of these tumors are seen involving neck, involving vagus nerve, and cervical sympathetic chain. Schwannomas involving mobile tongue are rarely encountered, especially in the pediatric population Case presentation We present a case of recurrent tongue schwannoma in a 13-year-old female successfully managed with transoral excision. At a follow-up of 3 years, no recurrence is observed. Conclusion Surgical excision is the recommended modality of treatment for lingual schwannomas, and when excised adequately, recurrences are not expected. A clear margin of surrounding normal tissue should be aimed for to avoid possible recurrence.

Lung transplantation offers life-saving and life-extending treatment for children and adolescents with congenital and acquired forms of pulmonary and pulmonary vascular disease, for whom medical therapy is ineffective or insufficient for sustained response. This review summarizes the pathology related to lung transplantation for the practicing pediatric pathologist and also highlights aspects of lung transplantation unique to the pediatric population. Clinical issues related to availability of organs, candidate eligibility, surgical technique, and postoperative monitoring are discussed. Pathologic evaluation of routine surveillance transbronchial biopsies requires attention to acute cellular rejection, opportunistic infection, and other forms of acute and resolving lung injury. These findings are correlated in some cases with endobronchial biopsies and bronchoalveolar lavage as adjunctive tools in surveillance. Open or thoracoscopic biopsies also have diagnostic utility in cases with acute or chronic graft deterioration of uncertain etiology. Future challenges in pediatric lung transplantation are similar to those in the adult population, with continued efforts focused on prolonging graft survival, prevention of bronchiolitis obliterans syndrome due to chronic cellular rejection, and evaluation of humoral rejection.

Peak oxygen consumption (V̇o2peak) strongly predicts morbidity and mortality better than other established risk factors, yet mechanisms associated with its age-associated decline are unknown. Our laboratory has shown that V̇o2peak first begins to decrease at the same age of 19–20 wk in both sedentary and wheel-running, female Wistar rats (Toedebusch et al., Physiol Genomics. 48: 101–115, 2016). Here, we employed a total systemic approach using unsupervised interrogation of mRNA with RNA sequencing. The purpose of our study was to analyze transcriptomic profiles from both sedentary (SED) and wheel-running (RUN) conditions as a strategy to identify pathways in the left ventricle that may contribute to the initial reductions in V̇o2peak occurring between 19 and 27 wk of age. Transcriptomic comparisons were made within both SED and RUN rats between 19 and 27 wk ( n = 5–8). Analysis of mRNAs shared in SED and RUN between 19 and 27 wk found 17 upregulated (e.g., Adra1d, Rpl17, Xpo7) and 8 downregulated (e.g., Cdo1, Ctfg, Sfrp1) mRNAs, at 19 wk, respectively. Furthermore, bioinformatics analysis of mRNAs common to SED and RUN produced networks suggestive of increased connective tissue development at 27 vs. 19 wk. Additionally, Ctfg mRNA was negatively associated with V̇o2peak in both SED and RUN ( P < 0.05). In summary, transcriptomic analysis revealed mRNAs and networks associated with increased connective tissue development, decreased α-adrenergic activity, and decreased protein translation in the left ventricle that could, in part, potentially influence the initiation of the lifelong reduction in V̇o2peak, independent of physical activity levels.

Abstract Background Midregional-proadrenomedullin (MR-proADM) is a useful prognostic peptide in severe infectious pathologies in the adult population. However, there are no studies that analyze its utility in febrile urinary tract infection (fUTI) in children. An accurate biomarker would provide an early detection of patients with kidney damage, avoiding other invasive tests like renal scintigraphy scans. Our objective is to study the usefulness of MR-proADM as a biomarker of acute and chronic renal parenchymal damage in fUTI within the pediatric population. Methods A prospective cohort study was conducted in pediatric patients with fUTI between January 2015 and December 2018. Plasma and urine MR-proADM levels were measured at admission in addition to other laboratory parameters. After confirmation of fUTI, renal scintigraphy scans were performed during the acute and follow-up stages. A descriptive study has been carried out and sensitivity, specificity and ROC curves for MR-proADM, C-reactive protein, and procalcitonin were calculated. Results 62 pediatric patients (34 female) were enrolled. Scintigraphy showed acute pyelonephritis in 35 patients (56.5%). Of those patients, the median of plasmatic MR-proADM (P-MR-proADM) showed no differences compared to patients without pyelonephritis. 7 patients (11.3%) developed renal scars (RS). Their median P-MR-proADM levels were 1.07 nmol/L (IQR 0.66–1.59), while in patients without RS were 0.48 nmol/L (0.43–0.63) (p < 0.01). The AUC in this case was 0.92 (95% CI 0.77–0.99). We established an optimal cut-off point at 0.66 nmol/L with sensitivity 83.3% and specificity 81.8%. Conclusion MR-ProADM has demonstrated a poor ability to diagnose pyelonephritis in pediatric patients with fUTI. However, P-MR-proADM proved to be a very reliable biomarker for RS prediction.

Otolaryngology involves the treatment of patients with diseases and disorders of the ear, nose, throat (ENT), and related structures of the head and neck. Many medical students in Canada have limited experiences in ENT and a vast majority of these students go on to pursue a career as primary care physicians. Physicians at a primary care facility classified patient’s visits as either being “ENT” related or not, to assess the amount of ENT related concerns they typically encounter. The data was collected separately in the summer and winter months to assess any seasonal variability. One in eight patient encounters presented with an ENT related concern. The percentage of ENT related symptom presentation visits in the pediatric population for both data collection periods (29%) was more than three times that of the adult population (9%). The rate of ENT symptom presentation in both adult and pediatric populations was not affected by seasonality. Primary care physicians will encounter new patients presenting with ENT related concerns quite frequently. This is especially true in the pediatric patient population. Increased ENT medical education is both necessary and essential for undergraduate medical students, residents, and primary care physicians.

AbstractThe present study is a case report of vulvar lipoma. The vulva is a rare site for the development of lipomas, and the aim of the study is to determine if the current imaging modalities can diagnose lipomas correctly. A 43-year-old patient presented with a painless, slowly progressive, oval, mobile and non-tender right vulvar mass compressing the vagina and totally covering the introitus. Both the ultrasonography and magnetic resonance imaging (MRI) exams suggested the diagnosis of lipoma. Surgical excision was performed, and the histopathological examination of the mass confirmed a lipoma.

Aim. To evaluate the prevalence and risk factors of H. pylori infection in the pediatric and adult population seen at a public hospital in São José do Rio Preto, SP, Brazil. Methods. This is a retrospective study that evaluated 2406 medical records of children, adolescents, and adults with dyspeptic symptoms who underwent upper gastrointestinal endoscopy. H. pylori diagnosis and demographic and clinical-pathological features were recorded. Results. A total of 852 subjects were H. pylori positive, with an overall prevalence of infection of 35.4%, occurring mainly in adults over 40 years of age, and a 24.7% prevalence considering only children and adolescents. No association was observed between H. pylori infection and risk factors. However, the H. pylori positive individuals showed a higher frequency of pangastritis (p<0.01), severe lesions (p=<0.001), and erosive lesions (p=0.04). The bacterium was eradicated in 83.5% (127) of the patients who received the standard therapy. Conclusions. The prevalence of H. pylori detected in a public service in São José do Rio Preto, SP, Brazil, is as expected for developed countries, showing growing rates with increasing age. As H. pylori infection occurs during childhood, screening programs for detection and prevention in the pediatric population are important to reduce the prevalence of this infection in adults.
