[ @entity409 with unusual expression of XXXX ( @entity3508 )].

@entity1 @entity5 @entity2 @entity5426 @entity409 @entity3508 @entity99
A 68-year-old male @entity1 presented with unspecific decline of general health, @entity5 in the liver discovered by ultrasound examination and a focus suggestive of @entity5 on chest x-ray. He was hospitalised because of suspected metastatic @entity2 . Laboratory analysis revealed a distinct elevation of serum @entity3508 ( @entity3508 , 26,1 micro g/l). A CT scan of the abdomen confirmed the presence of multiple @entity5 foci in both @entity99 , while the lung, however, was found to be free of @entity5 on CT-examination. Bronchoscopy, gastroduodenoscopy and colonoscopy were unremarkable. Subsequently, an ultrasound guided fine-needle biopsy of the liver was performed. Histological examination disclosed @entity5426 with unusual, though unequivocal expression of @entity3508 in @entity5 cells. As even follow-up examinations were unable to trace out any extrahepatic @entity5 , the @entity5426 was concluded to be of hepatic origin. The @entity1 succumbed to his disease 6 months later, an autopsy was not performed. This case report of a @entity3508 -producing primary @entity409 clearly outlines that a histological confirmation of an allegedly clear clinical diagnosis should always be performed because malignant @entity5 are capable of (co-)expressing so called @entity5 markers independently of their histogenesis.
