Summary
An 80-year-old male patient presented with a maxillary sinus mass. Histology revealed a malignant tumor, highlighting diagnostic challenges with cytokeratin expression.
Area of Science:
- Oncology
- Pathology
- Otorhinolaryngology
Background:
- Preoperative diagnostics can reveal unexpected findings.
- Maxillary sinus lesions require thorough investigation.
Observation:
- An 80-year-old male patient had an unclear lesion in the nasopharyngeal cavity during preoperative assessment.
- The lesion was identified as a dense soft tissue mass in the right maxillary sinus.
Findings:
- Histological examination showed a partially necrotically decomposed malignant tumor.
- The tumor was located beneath normal respiratory mucosa without dysplasia.
- Aberrant cytokeratin expression presented diagnostic difficulties.
Implications:
- This case underscores the complexity of differential diagnosis for sinonasal masses.
- Accurate histological interpretation, including cytokeratin analysis, is crucial for identifying malignant tumors.
- Challenges in diagnosing sinonasal malignancies necessitate advanced diagnostic techniques.
