Proposal for staging of inflammatory lesions in the frontal region.

Frontal swelling can be due to multiple etiologies, including: mucocele, Pott's puffy tumor, fibro osseous lesions, benign and malignant neoplasms of the nose and paranasal sinuses, intracranial lesions, and metastasis. The objective of this study was to describe the clinical protocol used for the diagnosis of patients presented with frontal swelling and the proposal for staging of inflammatory lesions. We performed an observational retrospective analysis. We found 7 cases of patients with frontal swelling: 4 cases secondary to inflammatory pathology (3 Potts puffy tumors and one frontal mucocele), and 3 cases secondary to neoplasms (one benign and 2 malignant neoplasms). It's very important to consider the wide differential diagnosis that can present as frontal swelling, from inflammatory pathologies secondary to possible advanced infections of the paranasal sinuses to invasive malignant neoplasms. We propose a system of staging of frontal inflammatory lesions.
