1,3] The major PLCA are papular (lichen), macular and nodular amyloidosis
Clonal light chain restricted primary intrapulmonary nodular amyloidosis.
Unusual cystic presentation of pulmonary nodular amyloidosis associated with MALT-type lymphoma.
PCLA is classified into lichen, macular,and nodular amyloidosis
12,35) As with nodular amyloidosis
, thin-walled air cysts would support the diagnosis.
Instead, pathology identified nodular amyloidosis
, which is associated with the AA type of amyloid.
DISCUSSION: Macular amyloidosis is one of the forms of primary localized cutaneous amyloidosis, others being lichen amyloidosis, nodular amyloidosis
and biphasic (macular +lichen) amyloidosis.
Of the several types of amyloidosis, nodular amyloidosis
is the type found most frequently in the larynx and nasopharynx, as well as in the trachea and lungs.
