Paroxysmal cold hemoglobinuria (PCH) is a rare condition in childhood characterized by complement-mediated premature destruction of red blood cells. PCH is associated with intravascular hemolysis causing hemoglobinuria, which may result in acute kidney injury of various severity. We aimed to retrospectively analyze clinical and laboratory features of children with PCH-associated acute kidney injury received at tertiary Pediatric Hematology and Nephrology Center, University Motol Hospital, Prague, Czech Republic during the period 2016 to 2022...

Pleomorphic xanthoastrocytoma (PXA) is a rare type of grade 2 or 3 brain tumor that usually occurs in children and young adults. The standard treatment for PXA is maximally safe resection, usually with adjuvant radiation therapy, for high-grade tumors. BRAF V600E mutation is one of the most common molecular alterations in these tumors, with nearly 70% of cases carrying this mutation. Although BRAF inhibitors have shown promise in treating progressive or refractory disease, their use has been associated with various adverse effects, including radiodermatitis, which is a relatively common complication...

Febrile neutropenia (FN) management in pediatric oncology patients traditionally necessitates inpatient admission until evidence of bone marrow recovery. Discharge before count recovery may be a way to safely reduce the length of hospitalizations for select patients. A chart review was conducted of patients admitted for FN at one tertiary care children's hospital, where the standard is to discharge well-appearing patients after 48 hours of negative cultures if afebrile for at least 24 hours, irrespective of absolute neutrophil count (ANC)...

Optic pathway gliomas (OPGs) are the most common pediatric optic nerve tumors. Their behavior ranges between rapid growth, stability, or spontaneous regression. Τhey are characterized by low mortality albeit with significant morbidity. We present the characteristics, management, and outcome of 23 OPG patients (16 females, median age: 4.8 y) managed in a Pediatric Oncology Department in Northern Greece over a 25-year period. Overall, 57% had a background of neurofibromatosis type 1. Diagnosis was based on imaging (10 patients) or biopsy (13 patients)...

Histiocytic sarcoma (HS) is a rare neoplasm with no known cause. This sarcoma is characterized by morphology similar to that demonstrated by mature tissue histiocytes and mostly afflicts adults. HSs typically have a poor prognosis due to a rapidly progressive clinical course. Our patient's case was unique due to its presentation four years after completion of treatment for B-cell acute lymphoblastic leukemia. The patient experienced progression with initial therapy for HS. With dual immunotherapy and radiation, however, the patient has remained clinically stable without detectable disease...

Human papillomavirus (HPV) vaccination prevents the development of HPV-associated malignancies. Adolescent and young adult survivors of childhood cancers and patients with sickle cell disease (SCD) are vulnerable patient populations who would significantly benefit from HPV vaccination. In this multimethod study, a retrospective chart review found a notable difference between the rate of HPV vaccinations and other age-appropriate vaccinations in 177 childhood cancer survivors and in 70 patients with SCD. We then sought to describe patient and caregiver beliefs regarding HPV vaccination, through semistructured interviews with 21 patients and 48 caregivers...

BACKGROUND: Delayed chemotherapy-induced vomiting (DCIV) is a problem for children undergoing chemotherapy for malignant tumors. The aim of this study was to investigate the association between body mass index (BMI) and DCIV in children. PATIENTS AND METHODS: Clinical data were collected from patients with malignancies who underwent chemotherapy at our center. Independent risk factors for DCIV derived by logistic regression. The Youden Index, which calculates BMI, divides patients into a high-risk group and a low-risk group, and the difference in DCIV between the two groups was analyzed...

Kaposi's sarcoma (KS) is a vascular / mesenchymal tumor with an indefinite degree of malignancy, caused by complex etiopathogenetic factors including Human Herpes Virus-8 infection of immunocompromised patients. For example, KS is more common in adult men with HIV. We describe 2 very rare cases of iatrogenic KS in children after hematopoietic stem cell transplant with isolated organ damage (case 1: lung; case 2: inguinal lymph node). KS is a potential complication of bone marrow transplant in pediatric patients and can occur in different age groups and at atypical sites...

As hospitalized pediatric patients have grown in number and complexity, and residency structural changes have reduced resident coverage, inpatient care models have changed to include additional providers at the "front line." Hospitalists are increasingly employed in general pediatric units, but in specialized inpatient areas, hospitalist care models are less common. Hospitalist programs in pediatric oncology are few and unique, and thus there are limited data assessing this role. Here we describe the oncology/stem cell transplant hospitalist program at the Children's Hospital of Philadelphia with a survey project to assess the perceptions of physicians in the role...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy, especially in pediatrics, that can involve the bone marrow, skin, lymph nodes, and central nervous system (CNS). Given its variable clinical presentation, coupled with an immunohistochemistry pattern (CD4, CD56, TCF4, TCL-1, and CD123 positivity) that differs from other myeloid neoplasms, the diagnosis of BPDCN can be missed. Limited data are available to guide the treatment of pediatric BPDCN. Herein, we report a case of a pediatric patient who had BPDCN with central nervous system, orbital, and skin involvement...

Germ cell tumors (GCTs) are associated with pure gonadal dysgenesis or Swyer syndrome. Swyer syndrome usually presents with primary amenorrhea, streak ovaries, and mixed GCT. However, our patient presented with secondary amenorrhea, normal female external genitalia, and a mixed GCT. Constitutional karyotype was suggestive of 46,XY. Management comprised chemotherapy, followed by surgery. Histopathology was suggestive of dysgerminoma complicating a gonadoblastoma. The purpose of reporting this case is its rarity and the importance of diagnosing an XY karyotype, as the incidence of GCTs is higher in these patients...

Ependymoma is the third most common brain tumor in children. Extracranial metastases of ependymomas are uncommon. A 21-month-old Japanese boy was diagnosed to be brain dead due to a posterior fossa (PF) brain tumor. Surgical resection of the tumor was not performed. Twenty-seven months later, he developed a truncal subcutaneous tumor, which was pathologically diagnosed as PF ependymoma group A. We observed the intracranial recurrence of the brain tumor, an invasion to the left orbit, and a neoplasm in his liver before he died...

Periodic fever is not uncommon in childhood and is often ascribed to autoinflammatory conditions; however, it may be present also in children with cancer. We here describe the case of a 3-year-old boy with acute lymphoblastic leukemia who initially presented with a 4-month history of recurrent, stereotyped episodes of fever and localized joint pain, separated by completely symptom-free intervals. These symptoms were initially interpreted as a possible syndrome of undifferentiated recurrent fever until more signs of leukemia became apparent...

Pheochromocytoma are chromaffin cell-derived tumors that have an exceptionally high genetic predisposition. The presentation of extra-adrenal and pelvic paraganglioma (PGL) in children is uncommon. Due to the relative rarity, PGL tumors' presentation and disease behavior may vary. Genetic testing, imaging, and biochemical investigation are employed to diagnose PGL. Surgical resection with preoperative angioembolization has been practiced in alleviating the burden of torrential intraoperative bleeding.

BACKGROUND: Nasopharyngeal (NP) swabbing is a technique that is commonly used to test pediatric patients for viral infections with increased use during the coronavirus disease 2019 pandemic. Complications from NP swabbing are rare and seem to occur more frequently in patients at risk of bleeding. Little is known about institutional or individual practices and experiences with NP swab testing in pediatric patients with risk factors for bleeding. METHODS: We conducted a survey study of pediatric hematology/oncology (PHO) attending physicians to assess practices and experiences with NP swab testing in pediatric patients with thrombocytopenia and/or on anticoagulation...

Understanding the molecular landscape of papillary thyroid carcinoma (PTC), the most common thyroid cancer in children, creates additional therapeutic approaches. RET gene rearrangements are observed in pediatric PTC, and selective inhibition of RET is now possible with specific tyrosine kinase inhibitors designed to target diverse RET-activating alterations. We present a 13-year-old female with metastatic PTC, clinically resistant to radioactive iodine, and found to harbor a NCOA4-RET fusion. She responded to selpercatinib treatment with the elimination of supplemental oxygen need, marked reduction in pulmonary nodules and mediastinal lymphadenopathy, and biomarker decline...

We report 2 children with distinct causes of polycythemia, 1 from systemic capillary leak syndrome (SCLS) and the other from protein-losing enteropathy (PLE) caused by CD55 deficiency. There is only a single case series about polycythemia in children with SCLS, but none on polycythemia in children with PLE. We present a 10-year-old girl with hypoalbuminemia, polycythemia, and edema who died as a result of an SCLS attack and a 1-year-old girl with PLE who was successfully treated with eculizumab. Our experience suggests that hematologists should be alert for SCLS and PLE in children with relative polycythemia...
