Summary
A rare pseudosarcomatous fibrovascular lesion mimicked subglottic angiosarcoma in a patient with stridor. Expert review confirmed the benign diagnosis, emphasizing diagnostic collaboration.
Area of Science:
- Pathology
- Otolaryngology
- Oncology
Background:
- Subglottic masses can present with airway obstruction.
- Distinguishing benign from malignant lesions is critical for patient management.
Observation:
- A patient initially diagnosed with asthma developed biphasic stridor due to a subglottic mass.
- Flexible nasendoscopy identified the obstructing lesion.
- Surgical removal with CO2 laser provided immediate symptomatic relief.
Findings:
- Histological examination was initially ambiguous, suggesting a primary subglottic angiosarcoma.
- Expert consultation and slide review led to a definitive diagnosis of pseudosarcomatous fibrovascular proliferation.
- This highlights the challenge in diagnosing rare subglottic lesions.
Implications:
- Emphasizes the importance of seeking expert pathological review for atypical diagnoses.
- Underscores the value of clinico-pathological correlation in complex cases.
- Suggests pseudosarcomatous fibrovascular lesions should be considered in the differential diagnosis of subglottic masses.
