[Ewing's papillomatosis. 3 cases (author's transl)]

Area of Science:

• Otolaryngology
• Pathology
• Oncology

Background:

• Ewing's papilloma is a rare sinonasal tumor.
• Understanding its clinical presentation and treatment is crucial for patient outcomes.
• This study details three distinct cases to further elucidate its characteristics.

Observation:

• Case 1: Unilateral epistaxis due to a nasal septum tumor, successfully resected with no recurrence at 10 years.
• Case 2: Nasal obstruction from Ewing's papillomatosis with dysplastic changes, complicated by a co-existing cavernous hemangioma—a novel combination.
• Case 3: Sinusitis with polyps initially treated, followed by recurrence requiring a second wide excision for Ewing's papilloma.

Findings:

• Ewing's papilloma can present with varied symptoms, including epistaxis and nasal obstruction.
• Recurrence is possible, necessitating thorough surgical management and follow-up.
• The co-occurrence of Ewing's papilloma and cavernous hemangioma is a rare finding.

Implications:

• Highlights the importance of comprehensive histopathological evaluation in sinonasal tumors.
• Emphasizes the need for individualized surgical approaches based on tumor presentation and extent.
• Suggests further research into the pathogenesis and management of complex sinonasal pathologies.
