XXXX : Pitfalls in the diagnosis on fine needle cytology and "small biopsy" and review of the literature.

@entity1 @entity455 @entity353 @entity1350 @entity158 @entity3 @entity99
UNASSIGNED: @entity99 is a rare @entity1350 with an unpredictable malignant potential. Different therapeutic options are available, depending on the basis of disease extension and the @entity1 's overall condition. A correct pathological diagnosis is necessary and is often based on scant material. Here, we report a case diagnosed on fine needle aspiration and on a small surgical biopsy. In addition, we will review the literature. The @entity1 is a 54-year-old @entity1 who presented with persistent @entity158 in the right hypochondrium and suffered from @entity353 . Ultrasound examination and CT scan showed several focal and confluent hepatic lesions. Thus, an ultrasound-guided fine-needle aspiration (US-FNA) was performed. A cytological diagnosis of @entity455 with epithelioid component was performed. Afterwards, a hepatic "small biopsy" (SB) was made. Histological and immunohistochemical data were consistent with a @entity99 diagnosis. The @entity1 , however, is in good general condition and is waiting for a hepatic transplantation; repeated total CT scan showed no signs of @entity3 . The literature was reviewed in order to define the pathological features that were helpful in the cytological and histological diagnosis of @entity99 , and to better understand if pathological data is prognostically useful.
