[Occult XXXX presenting as an @entity1283 ].

@entity1 @entity0 @entity5 @entity1283 @entity420
The authors discuss ten cases of occult @entity0 which presented initially as the @entity1283 . All cases were proven as @entity420 . Both mammography and ultrasonography revealed the @entity5 in 3 cases, while in the remaining 7 cases malignant lumps were not visualized. Multiple studies to detect an extra mammary site proved to be negative. A concealed @entity0 was found in 9 @entity1 with careful sectioning of the resected breast specimens. Only one @entity1 in whom @entity0 could not be detected has survived well for 6 years after the mastectomy. Parasternal node involvement was not identified in all 7 @entity1 of who had received an extended radical mastectomy. Three @entity1 died of the disease within 45 mo. Seven @entity1 are free of recurrence for 1 to 10 years (average 6 1/2 Y). Prognosis of the @entity1 in this group are as good as and/or sometimes better than those of the @entity1 with axillary nodes pathologically positive.
