Pleural amyloidosis is a rare condition. Diagnosis was achieved in two patients with large pleural effusions using biopsy, including one Cope needle biopsy, highlighting diagnostic utility.

Area of Science:

Pulmonology
Pathology
Medical Diagnostics

Background:

Pleural amyloidosis is an uncommon condition characterized by amyloid deposition in the pleura.
Diagnosis typically relies on tissue biopsy, but it is rarely reported in pleural effusions.

Observation:

Two cases of pleural amyloidosis presenting with large, unilateral pleural effusions were identified.
One case was diagnosed using a Cope needle biopsy, a method seldom documented for this condition.

Findings:

Biopsy specimens from pleural effusions confirmed pleural amyloidosis in both patients.
The Cope needle biopsy was effective in diagnosing pleural amyloidosis in one of the reported cases.

Implications:

This study underscores the potential of pleural biopsy, including Cope needle biopsy, in diagnosing rare cases of pleural amyloidosis.

These findings may encourage consideration of pleural biopsy in unexplained large pleural effusions.

Further research into diagnostic modalities for pleural amyloidosis is warranted.
