Sinonasal teratocarcinosarcoma, a rare and aggressive tumor, requires detailed biopsy for diagnosis. This case highlights successful management through endoscopic surgery and radiotherapy for a nasoethmoidal mass with intracranial extension.

Area of Science:

Oncology
Pathology
Surgical Oncology

Background:

Sinonasal teratocarcinosarcoma is an exceptionally rare neoplasm with uncertain origins.
Accurate diagnosis hinges on meticulous examination of biopsy specimens.
This aggressive tumor presents a significant clinical challenge with a 5-year survival rate of approximately 45%.

Observation:

A 38-year-old male presented with a left nasoethmoidal mass.
The mass exhibited erosion of the cribriform plate and intracranial extension.
Subtotal endoscopic excision was performed for diagnostic and therapeutic purposes.

Findings:

Histopathological examination confirmed the diagnosis of sinonasal teratocarcinosarcoma.
Immunohistochemistry further validated the tumor's specific characteristics.

Keywords:

Sinonasal Mass Teratocarcinosarcoma
