Amyloidoma of the chest wall: a rare entity.

Amyloidoma (tumoral amyloidosis) is defined as a solitary localized tumor-like deposit of amyloid, in the absence of systemic amyloidosis. Amyloidoma is the least common presentation of tissue amyloid deposition, reported in many anatomic sites including the respiratory, genitourinary and gastrointestinal tracts, as well as the central nervous system, skin, breast and soft tissue. Amyloidoma of the chest wall is extremely rare, and to date only one case has been reported in literature. The authors present a case of a chest wall tumor that causes local destruction, being an amyloidoma on histopathologic examination. It was treated with wide local excision, with no recurrence during almost two years of follow-up. A search for occult systemic disease is recommended and was also performed.
