Summary

Sinonasal leiomyomas are rare benign tumors originating from smooth muscle. Histological examination is crucial for diagnosing these tumors, as they lack distinct clinical or radiological features.

Area of Science:

Otolaryngology
Pathology
Oncology

Background:

Sinonasal tumors are predominantly of epithelial origin.
Leiomyomas are exceedingly rare in the sinonasal tract, accounting for <2.5% of mesenchymal neoplasms.
This study contributes to the limited literature on sinonasal leiomyogenic tumors.

Observation:

A case of a 48-year-old woman with nasal obstruction due to a sinonasal polypoid lesion is presented.
The lesion was surgically removed and diagnosed as a leiomyoma.
This adds to the approximately 30 previously reported cases.

Findings:

Sinonasal leiomyomas exhibit no specific physical or radiological characteristics.
Definitive diagnosis relies solely on histopathological examination.

The tumor presented as a polypoid lesion causing nasal obstruction.

Implications:

Accurate histological diagnosis is paramount for appropriate management of sinonasal leiomyomas.
Increased awareness of this rare entity is needed among clinicians and pathologists.
Further research may elucidate specific diagnostic markers or treatment strategies.
