Epithelial (inverted) papilloma: a correlated radiological--histological study
Clinical Radiology
|September 1, 1977
Summary
Epithelial papilloma typically presents as a nasal mass with sinus opacification. Bone destruction can occur due to pressure or direct invasion if carcinoma is present.
Area of Science:
- Radiology
- Pathology
- Otolaryngology
Background:
- Epithelial papilloma is a benign tumor affecting the sinonasal tract.
- Accurate diagnosis relies on understanding its radiological and pathological characteristics.
Purpose of the Study:
- To describe the radiological and pathological features of epithelial papilloma.
- To differentiate features associated with benign papilloma versus malignant transformation.
Main Methods:
- Retrospective review of 14 cases of epithelial papilloma.
- Analysis of radiological imaging (e.g., CT, MRI) and histopathological findings.
Main Results:
- Typical radiological findings include a unilateral nasal mass and sinus opacification.
- Mass extension into the nasopharynx was occasionally observed.
- Bone destruction may be present, attributed to pressure erosion or direct carcinomatous invasion.
Conclusions:
- Radiological and pathological evaluation is crucial for diagnosing sinonasal epithelial papilloma.
- Distinguishing pressure erosion from direct invasion is important for treatment planning.
