Multiple endobronchial granular cell myoblastomas discovered at bronchoscopy

Area of Science:

• Pulmonology
• Oncology
• Pathology

Background:

• Granular cell tumors (GCTs) are uncommon neoplasms.
• Endobronchial GCTs typically present with symptoms.
• Multiple GCTs in the bronchial tree are exceptionally rare.

Observation:

• A case of multiple endobronchial GCTs is presented.
• The tumors were asymptomatic.
• Incidental discovery during bronchoscopy.

Findings:

• The case involved multiple GCTs within the bronchial tree.
• The patient remained asymptomatic throughout the two-year follow-up.
• Diagnostic bronchoscopy led to the incidental finding.

Implications:

• This case expands the understanding of GCT presentation.
• Highlights the importance of incidental findings during bronchoscopy.
• Suggests that asymptomatic endobronchial GCTs can occur.
