Pulmonary amyloidoma, a rare benign lung lesion, can present as a large mass. Complete surgical removal of this isolated case led to no recurrence, highlighting effective treatment for this uncommon condition.

Area of Science:

Pulmonology
Pathology
Oncology

Background:

Amyloidoma, a localized form of pulmonary nodular amyloidosis, is an uncommon cause of benign lung lesions.
Solitary lesions are often termed amyloidoma, but extensive presentations are rare.

Observation:

A 45-year-old male presented with hemoptysis and eosinophilia.
Imaging revealed a large mass involving the left lung, chest wall, and liver, initially suspected to be an echinococcal cyst.
The mass was surgically excised en bloc, bypassing diagnostic biopsy due to its size and suspected etiology.

Findings:

Histopathological examination confirmed the resected mass as an isolated pulmonary amyloidoma.
Complete resection was achieved without complications.
No evidence of recurrence was observed post-surgery.

Implications:

This case demonstrates that extensive pulmonary amyloidoma, though rare, can be successfully treated with complete surgical resection.
Early diagnosis and surgical intervention are crucial for managing large amyloidoma masses.
Further research into the pathogenesis and optimal management of pulmonary amyloidoma is warranted.
