Nasal Tumor Misdiagnosed as Carcinoma

Accurate histopathologic evaluation and complete excision distinguished a rare benign lesion from squamous cell carcinoma and guided management.

1

A 71-year-old female presented with progressive right-sided nasal obstruction and a vascular lesion in the nasal passage.
2

Initial biopsy findings suggested a diagnosis of invasive squamous cell carcinoma, leading to surgical intervention.
3

Surgical removal revealed a well-encapsulated pleomorphic adenoma, differing from the initial carcinoma diagnosis.
4

Histopathologic evaluation confirmed the pleomorphic adenoma, characterized by mixed epithelial and mesenchymal components.
5

Follow-up at 3 and 6 months showed no recurrence, although nasal asymmetry persisted, highlighting the need for ongoing monitoring.
