Sclerosing hemangioma is an uncommon tumor of unknown histogenesis that generally develops in the lung. We report on a 48-year-old woman with a sclerosing hemangioma that was apparently isolated to the mediastinum. To our knowledge, sclerosing hemangioma arising in the mediastinum has not been previously reported. Potential mechanisms explaining the isolation of sclerosing hemangioma in the mediastinum are discussed.

Angiomatoid fibrous histiocytoma (AFH) is a rare intermediate tumor that is often difficult to diagnose radiologically and pathologically. Herein, we report a case of AFH in the knee that was initially misdiagnosed as a cystic lesion. The tumor was first identified eight years earlier during the patient's initial visit, when plain magnetic resonance imaging (MRI) was performed, leading to a diagnosis of a cystic lesion.

This report describes a rare occurrence of benign fibrous histiocytoma in the frontal sinus of a 38-year-old male. The patient presented with acute symptoms, including sudden-onset headache, nausea, and general discomfort, although neurological, otorhinolaryngological and laboratory examinations showed no abnormalities. A cranial CT scan revealed a cystic, osteodestructive lesion measuring 2.

Pulmonary sclerosing pneumocytoma is a rare benign neoplasm typically seen in middle-aged women. The exact preoperative diagnosis is quite challenging considering its nonspecific clinical and radiologic features along with complex histology. Moreover, obtaining an exact histopathological diagnosis can be difficult especially with the small biopsy specimens.

Background: Intranodal hemangiomas are rare benign vascular tumors of the lymph nodes, often misdiagnosed as malignant lymphadenopathies due to their clinical and radiological features. This case report and systematic review aim to elucidate the epidemiology, clinical profile, and therapeutic interventions for intranodal hemangioma, enhancing diagnostic accuracy and management.
Methods: A systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
