Sclerosing Mediastinitis Masquerading As A Lymphoma.

Area of Science:

• Oncology
• Pharmacology
• Pathology

Background:

• Fibrosing retroperitoneal changes are often mistaken for malignant tumors.
• A known association exists between beta-blocker medications and these fibrotic changes, with practolol being an early example.
• Later-generation beta-adrenergic receptor blocking drugs have also been implicated.

Purpose of the Study:

• To report a case of supradiaphragmatic fibrosing pathology linked to beta-blocker use.
• To highlight the potential for this condition to be misdiagnosed as lymphoma.
• To emphasize the importance of considering this rare association in the differential diagnosis of abdominal and chest mass lesions.

Main Methods:

• Case report and literature review.
• Clinical and radiological assessment of a patient presenting with mass lesions.
• Histopathological examination to confirm diagnosis.

Main Results:

• A case of supradiaphragmatic fibrosing pathology associated with later-generation beta-blocker use was identified.
• The presentation mimicked malignant lymphoma.
• This highlights a rare but significant drug-induced condition.

Conclusions:

• Fibrosing conditions associated with beta-blockers can occur in the chest and mimic malignancy.
• This rare association, including with newer beta-blockers, should be considered in the differential diagnosis of abdominal and chest masses.
• Prompt recognition can prevent misdiagnosis and guide appropriate management.
