A rare case of hepatocellular tumor extension in the right heart was reported. The patient presented with clinical signs of a vena cava superior syndrome. Computed tomography and transthoracic echocardiography demonstrated a large tumoral mass lesion extending from the left liver lobe into the inferior vena cava right atrium and right ventricle. The patient was treated with best supportive care.

In the present study we considered the histology of 51 patients who have undergone breast conservative surgery and the related 54 re-excisions that were performed in the same surgical procedure or in delayed procedures, in order to evaluate the role of intraoperative re-excisions in completing tumor removal. In 13% of the cases the re excision obtained the resection of the target lesion. In thi...

OBJECTIVE To analyze the contrast-enhancement patterns obtained at pulse-inversion harmonic imaging (PIHI) of focal hepatic lesions, and to thus determine tumor vascularity and the acoustic emission effect. MATERIALS AND METHODS We reviewed pulse-inversion images in 90 consecutive patients with focal hepatic lesions, namely hepatocellular carcinoma (HCC) (n=43), metastases (n=30), and hemangi...

99mTc-octreotide scintigraphy, performed during the following up a 58-year old man with neuroendocrine tumor demonstrated massive hepatomegaly demonstrating multiple areas of increased and decreased uptake. Due to severe hepatomegaly concurrence of any other abdominal soft tissue lesions could not be excluded. A 99mTc-sulfur colloid scan was done and thoroughly compared wi...

background: a solitary necrotic nodule (snn) of the liver is an uncommon lesion, which is different from primary and metastatic liver cancers. objectives: to analyze the classification, ct and mr manifestation, and the pathological basis of solitary necrotic nodule of the liver (snn) in order to evaluate ct and mri as a diagnosing tool. patients and methods: this study included 29 patients with...

background autoimmune hepatitis (aih) is a form of chronic hepatitis with unclear causative factors and is characterized by immunological and auto-immunological manifestations. several extrahepatic manifestations, such as other autoimmune disorders, are associated with aih. aih with dermatological conditions as the initial manifestation is rare. we report the case of aih in which erythema nodos...

OBJECTIVE to evaluate the influence of Ki-67 and P16INK4a proteins immunohistochemical expressions on the clinical and morphological parameters of perioral squamous cell carcinoma induced with 9,10-dimethyl-1,2-benzanthracene (DMBA) in mice. METHODS we topically induced the lesions in the oral commissure of ten Swiss mice for 20 weeks, determining the time to tumors onset and the average tumo...

Transcription factors play a central role in the epithelial-mesenchymal transition (EMT), which is one of the biomolecular mechanisms involved in the progression of urothelial carcinomas of the bladder (UCB). In this study, we analyzed the immunoexpression of Twist 1, Snail, Slug and β-catenin in relation to histopathological prognostic parameters of UCB. The obtained results indicated the asso...
