Primary amyloid tumor (amyloidoma) of the jejunum with spheroid type of amyloid

The present report documents an incidentally discovered, solitary amyloidom a of the jejunum in a 70 year old man with no predisposing disorder or othe r sites of deposition of amyloid, as was demonstrated at autopsy. Amyloid t umors of the intestine have been reported only rarely. In those reports the deposits were conventional in type, forming large masses of acellular, eos inophilic, homogeneous material. In the case described here the deposits we re in the form of corpora amylacea-like structures, or spheroids. To the be st of our knowledge, the corpora amylacea-like structures, or spheroid amyl oid, have not been previously described in bowel amyloidoma. This rare form of amyloid deposition should be recognized so as to prevent misdiagnosis.
