Recurrent endobronchial diffuse large B-cell lymphoma. Diagnosed by cryoprobe.

Area of Science:

• Pulmonology
• Oncology
• Pathology

Background:

• Diffuse large B-cell lymphoma (DLBCL) rarely involves the bronchi.
• Histological diagnosis of bronchial DLBCL necessitates adequate lung tissue samples.
• Immunohistochemistry is crucial for diagnosing bronchial DLBCL, often requiring repeat biopsies.

Observation:

• Presents the first documented case of recurrent endobronchial DLBCL.
• Diagnosis was established from a bronchial biopsy obtained using a cryoprobe.
• This method facilitated tissue acquisition for definitive diagnosis.

Findings:

• Cryoprobe biopsy successfully diagnosed recurrent endobronchial DLBCL.
• Demonstrates the utility of cryoprobes in obtaining adequate tissue for rare pulmonary lymphomas.
• Highlights a minimally invasive approach for diagnosing challenging cases.

Implications:

• Suggests cryoprobe biopsy as a valuable tool for diagnosing endobronchial malignancies.
• May reduce the need for repeat endoscopic procedures in similar cases.
• Advances diagnostic strategies for rare pulmonary oncological conditions.
