Nine pediatric cases of solitary eosinophilic granuloma (EG) are reported. Six children harbored cranial lesions and three had spinal involvement. Plain radiographs and computed tomography scan were not always sufficient for diagnosis. Isotopic bone scan was useful to rule out multiple lesions. The authors' opinion is that surgical excision is the treatment of choice for cranial lesions, leaving radiotherapy for possible relapse. Management of EG of the spine should start with needle biopsy, followed by radiation therapy, surgery being indicated in selected patients with immediate risk of neural compression. Mean follow-up time was 4.4 years (longer than several reported series). At the time of revision all children were asymptomatic, and only one case presented a local recurrence that was managed by radiotherapy.

Introduction And Importance: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular tumor characterized by abnormal endothelial proliferation and inflammatory cell infiltration, primarily affecting the head and neck region. The diverse clinical presentations of ALHE pose significant diagnostic challenges, often leading to misdiagnosis. Accurate histopathological examination is crucial for differentiating ALHE from other vascular lesions and guiding appropriate treatment.

Soft tissue tumors with EWSR1/FUS fusion to genes encoding the cyclic adenosine monophosphate response element-binding (CREB) transcription factor family (ATF1, CREB1, and CREM) are rare and heterogeneous aggressive tumors, often found in the peritoneal cavity. Here, we report two cases of malignant epithelioid tumors with EWSR1::CREB fusion involving the kidney in females in their 30 s. Both tumors appeared as solitary masses, measuring 5.

To investigate the clinicopathological features, immunophenotype, molecular characteristics, and differential diagnosis of primary intracranial DICER1-mutant sarcoma in order to better understand this tumor type. A retrospective analysis was conducted on 7 cases of primary intracranial DICER1-mutant sarcoma diagnosed in the Department of Pathology, Sun Yat-sen University Cancer Center, Guangzhou, China between 2021 and 2023 using next-generation sequencing. At the same time, 10 gliosarcomas, 4 intracranial FET::CREB fusion-positive mesenchymal tumors, 4 malignant meningiomas, 3 malignant solitary fibrous tumors, 3 malignant peripheral nerve sheath tumors, 3 synovial sarcomas and 3 rhabdomyosarcomas (total 30 cases) were selected as control.
