Summary
This study reports the first obstructive endobronchial mass caused by Richter's transformation, a rare complication of chronic lymphocytic leukemia. Treatment with Nd-YAG laser and chemotherapy successfully resolved the airway obstruction.
Area of Science:
- Oncology
- Hematology
- Pulmonology
Background:
- Richter's transformation is a rare but serious complication of chronic lymphocytic leukemia (CLL).
- Endobronchial involvement in Richter's transformation is exceptionally uncommon, with limited prior reports focusing on diffuse mucosal infiltration.
Observation:
- A 60-year-old male patient with CLL presented with recurrent lingular pneumonia.
- Fiberoptic bronchoscopy revealed an endobronchial mass obstructing the lingula and left upper lobe.
- Biopsy confirmed the mass as anaplastic large cell lymphoma, consistent with Richter's transformation.
Findings:
- This case represents the first documented instance of an obstructive endobronchial mass due to Richter's transformation.
- The patient's endobronchial mass was successfully managed using Nd-YAG laser therapy to maintain airway patency.
- Combined treatment with laser therapy and chemotherapy led to complete resolution of the endobronchial mass.
Implications:
- This case expands the known spectrum of endobronchial manifestations of Richter's transformation.
- Endobronchial obstruction should be considered in CLL patients presenting with unexplained pulmonary symptoms.
- Multidisciplinary management involving bronchoscopic intervention and systemic therapy can effectively treat this rare condition.
