IgG4-related disease is a newly recognized fibroinflammatory disorder that has the ability to affect nearly every organ system. It is characterized by tumefactive lesions and fibrosis and closely mimics neoplasms. Only one case of IgG4-related bladder mass has been reported in the literature, but there are no reports of IgG4-related disease in a urachal mass. Herein, we report a 26-year-old mal...

a young known case of multiple sclerosis was evaluated with chief complaint of gradually progressed left lower limb weakness over 3 weeks. pathologic examination of a mass in brain magnetic resonance imaging confirmed the diagnosis of glioblastoma multiforme (gbm). given the importance of the definite diagnosis of malignant glioma and its effect on patient’s management, gbm should be considered...

Calcifying pseudoneoplasm of the neuraxis (CAPNON) is a rare tumefactive lesion with unclear pathogenesis. It diagnosed by pathological findings typical histological features that include granular amorphous cores palisading spindle to epithelioid cells, variable fibrous stroma, foreign-body reaction giant and calcification/ossification occasionally psammoma bodies. However, its histopathology m...

BACKGROUND Immunoglobulin G4-related disease is characterized by infiltration of immunoglobulin G4-positive plasmacytes in various organs. The radiological findings of lung involvement of immunoglobulin G4-related disease include hilar and mediastinal lymphadenopathies, thickness of bronchovascular bundles, peribronchovascular consolidation, and lung nodules. Although a pathological approach is...
