[Primary amyloid tumor of the breast. Case report and review of the literature].
Along with an introductory summary concerning practically with all types of amyloidoses the authors report on a case of a primary amyloid tumor in a female patient, which resulted the eight after a computer-assisted literature search. Amyloid deposits in the breast represent an extremely rare event, which has been described in three clinical settings, in patients with reactive or secondary amyloidosis, in patients with immunocytic amyloidosis (this term including both the so-called primary form and the myeloma-associated form), and finally even in patients who are well and otherwise asymptomatic. Amyloid deposits in the breast can occur in the course of a systemic involvement as well as in form of a localized or organ-limited disease ("amyloid tumor"). Further the latter form is qualified as a "secondary amyloid tumor" (in those patients affected by certain neoplastic diseases, plasmacellular or non plasmacellular, or by a chronic infectious-inflammatory-dysreactive process) or as a " primary amyloid tumor" in those who are found free of any disease and of any other amyloid deposits. The case the authors report on deals with a lady who was admitted due to a breast lump which mammographically was thought suspicious for malignancy by virtue of a cluster of variously sized microcalcifications. At histology the lesion was diagnosed as an amyloid deposit on special stains and disclosed of the AL type with Congo red stain on sections previously treated with KMn04, according to standard methods.(ABSTRACT TRUNCATED AT 250 WORDS)
