We report a rare case of pulmonary intravascular papillary endothelial hyperplasia. The patient was a 63-year-old male. Multiple lung nodules were noted on chest computed tomography( CT) at preoperative check for gastric cancer. Metastatic lung tumor was suspected, and partial resection of the right lung was performed. Histopathologic examination revealed papillary proliferation lined by endothelial cells and a hematoma. Immunohistochemically, the endothelial cells were positive for CD31/CD34 and factor VIII related antigen.

University of Alberta, Department of Otolaryngology - Head & Neck Surgery.
Intravascular Papillary Endothelial hyperplasia (IPEH) are benign vascular lesions rarely described in the pediatric population. We present here the case and the management of a 11-year-old child with a lateral neck mass. The diagnosis of IPEH can be challenging for the clinician and the radiologist as it may mimic other pathologic entities.

Background: Generalized lymphatic anomaly (GLA) is a rare congenital lymphatic malformation (LM) characterized by multiple infiltrating lymphangiomas in various tissues. Owing to its rarity, information on this disease is obtained mainly through case reports, leading to delayed diagnosis. In this study, we reported a case of generalized lymphatic anomaly in a pediatric patient manifesting as hemorrhagic pleural effusion.

Background: Muscle-invasive bladder cancer (MIBC) is a prevalent cancer characterized by molecular and clinical heterogeneity. Assessing the spatial heterogeneity of the MIBC microenvironment is crucial to understand its clinical significance.
Methods: In this study, we used imaging mass cytometry (IMC) to assess the spatial heterogeneity of MIBC microenvironment across 185 regions of interest in 40 tissue samples.
Non-clear cell renal cell carcinoma narrative review: where we are in 2024.

November 2024
Division of Hematology and Oncology, Department of Internal Medicine, Froedtert & the Medical College of Wisconsin, Milwaukee, WI, USA.
Article Synopsis
- Advances in understanding non-clear cell renal cell carcinoma (RCC) have improved due to better molecular and genetic testing, helping to identify specific subtypes and personalize treatment.
- Representation in clinical trials for rare non-papillary RCC variants is limited, making evidence-based management difficult.
- The shift toward molecular diagnostics is enhancing our knowledge of RCC behaviors and responses to treatments, although most evidence comes from smaller clinical studies rather than extensive trials.
Successful Aflibercept Treatment for Choroidal Neovascularization in a Rare Case of Optic Disc Melanocytoma.
Am J Case Rep
December 2024
Department of Oncology-Ophthalmology, Curie Institute, Paris, France.
Article Synopsis
- Optic disc melanocytoma is a benign, usually asymptomatic tumor found in the eye, but it can lead to complications like choroidal neovascularization, which can be challenging to distinguish from malignant tumors.
- A case study of a 54-year-old man with optic disc melanocytoma showed the need for close monitoring due to growth, prompting treatment with anti-VEGF-A injections after development of neovascular membranes.
- Treatment with intravitreal anti-VEGF-A can effectively manage choroidal neovascularization related to optic disc melanocytoma and requires advanced imaging techniques for accurate diagnosis.
