Giant intracranial aneurysms are rare vascular pathologies associated with high morbidity and mortality. The purpose of this in vivo study was to assess giant intracranial aneurysms and their wall microstructure by 7T MR imaging, previously only visualized in histopathologic examinations. Seven giant intracranial aneurysms were evaluated, and 2 aneurysms were available for histopathologic exami...

background and aims. histpathologic diagnosis of exophytic lesions is occasionally influenced by clinical and radiographic diagnosis and even the surgeon’s observation during biopsy. the aim of this study was to evaluate the cases with failure in clinical diagnosis. materials and methods. a total of 73 patients with peripheral exophytic lesions were evaluated in zahedan faculty of dentistry in ...

BACKGROUND Spitz nevus is a benign melanocytic lesion sometimes mistakenly diagnosed clinically as melanoma. OBJECTIVE Our aim was to evaluate in vivo reflectance-mode confocal scanning laser microscopy (CSLM) aspects of globular Spitz nevi and to correlate them with those of surface microscopy and histopathology. METHODS A total of 6 Spitz nevi, with globular aspects on epiluminescence obs...

Numerous distinct neoplasms are encountered at the anterior cranial base. Management of these primary tumors and their locoregional recurrences are dictated by the histopathologic diagnosis. We present two unusual cases of extra-axial anterior cranial base malignancies with locoregional recurrence where the recurrent tumor encountered was of a distinct histopathologic type. While rare, this rep...
