[A rare manifestation of a cystic lung disease with high suspicion of pulmonary light chain deposition disease (LCDD)].
WHY IT MATTERS
If you have been diagnosed with an unusual cystic lung disease that doesn't fit typical patterns, your doctor should consider testing for light chain deposition disease, which requires specific blood work and imaging to confirm.
Doctors found a rare lung disease called pulmonary light chain deposition disease (PLCDD) that creates cysts and bumps in the lungs. This disease is hard to diagnose because it looks similar to other lung conditions, but special imaging scans and blood tests for abnormal proteins can help identify it. The article explains how doctors should think about this disease when patients have unusual cyst patterns in their lungs.
[A rare manifestation of a cystic lung disease with high suspicion of pulmonary light chain deposition disease (LCDD)]. Abstract: This case report describes a rare form of cystic lung disease, strongly suspected to be a pulmonary manifestation of light chain deposition disease (LCDD). Pulmonary light chain deposition disease (PLCDD) is an uncommon form of cystic lung disease, presenting with extensive bilateral cysts and nodules. Definitive diagnosis requires histopathological confirmation, although this may not always be feasible in cases of respiratory compromise. The diagnosis of LCDD should be considered when the clinical findings are atypical for other cystic lung diseases, the HRCT morphology suggests nodular-cystic amyloidosis (HRCT with cysts and nodules, nodules also involving the walls of the cysts, predominantly located in the periphery of the lower lung areas) or when monoclonal free light chains, particu Authors: Sicker et al.

ASK YOUR DOCTOR
If you have a cystic lung disease diagnosis that seems atypical or unclear, ask your pulmonologist whether light chain deposition disease has been ruled out and whether you've had testing for monoclonal free light chains in your blood.
