Inflammatory Pseudotumor of an Orbito-Maxillary Mass Masquerading as a Malignancy

Conclusion: Histopathologic diagnosis of Inflammatory Pseudotumor is difficult and differentiating it from malignant tumors is often a concern for otolaryngologists and pathologists. In spite of an initial malignant biopsy result, the combination of clinical signs and symptoms and radiologic findings of an infiltrative mass lesion, should not discount the possibility of a benign entity such as Inflammatory Pseudotumor for which treatment is conservative.
