Abstract

Immunoglobulin G4 (IgG4)-related sclerosing disease is characterized by a systemic involvement of tumor-like lesions with IgG4-positive plasma cell. This disease can occur in the salivary, lacrimal and pituitary gland in the head and neck region. The involvement of IgG4-related sclerosing disease at nasopharynx is extremely rare, so it is hard to make an accurate diagnosis. Recently, we have experienced two cases of IgG4-related sclerosing disease arising from the nasopharynx. Diffusely enhancing mass with surrounding bony erosion and increased 18-F fludeoxyglucose uptake was found at the nasopharynx, suggesting malignancy. But the cases were finally confirmed as IgG4-related sclerosig disease by punch biopsy and the symtoms improved with glucocorticoid therapy. We report our experiences with a literature review.
