A 1.5-year-old, neutered, male ferret (Mustela putorius furo) was presented with sudden lethargy, anorexia, and diarrhea. Clinical and radiographic examinations revealed an intra-abdominal mass. An explorative laparotomy was performed. A neoplasm, located in the ileum wall, was submitted for histopathologic examination. The tumor consisted of weakly eosinophilic spindle cells arranged in a comp...

Oral plasmablastic lymphoma (PBL) is a rare malignancy, associated with HIV or other immunocompromised conditions. The lesion constituted a new subtype of diffuse large B-cell lymphoma and proposed a distinct entity based on its basic morphology, its clinical behaviour involving predominantly extramedullary sites (particularly oral cavity), and its limited antigenic phenotype data suggesting pl...

introduction: the purpose of this study was to compare the histopathologic reaction of four suturing materials: silk, polyvinylidene fluoride (pvdf), polyglycolic acid, and catgut in the oral mucosa of albino rabbits. materials and methods: the twenty-one male mature albino rabbits which were used in this study were randomly divided into three groups of seven each. silk, pvdf, polyglycolic acid...

The aim of the study was to determine a combination of anthropometric variables that would enable better differentiation between benign and malignant ovarian masses. Prospective study has been performed in a two year period in which 208 women with ovarian lesions were analyzed and correlated with histopathologic surgical findings. We examined the relation between self-reported anthropometric an...

Neoplastic lesions that demonstrate neuroendocrine features are rare. However, esophageal tumors containing both adenocarcinomatous and neuroendocrine components are exceedingly rare. Mixed adenoneuroendocrine carcinomas (MANECs) are gastrointestinal tumors with both adenocarcinomatous and neuroendocrine differentiation. They have a tendency for early metastases but clinically manifest relative...

Hepatocellular adenoma (HCA) is a benign liver tumor most frequently occurring in women using oral contraception. HCA develops in normal or nearly normal livers and is extremely rare in cirrhosis. The authors present magnetic resonance imaging and histopathologic findings in a 57-year-old man with liver cirrhosis and hepatic adenomatosis. As the differentiation between HCA and hepatocellular ca...

Eccrine syringofibroadenoma (ESFA) is a rare benign cutaneous adnexal lesion characterized by a hyperplastic epithelium and eccrine ductal differentiation. In the present case, a 73-year-old Korean male presented with symmetrical numerous widespread, pinkish nodules with a cobblestone appearance over both legs for 2 years. He had a history of generalized erythematous scaly patches over his enti...

OBJECTIVES To characterize and quantitate optic nerve histopathologic and morphometric differences between optic nerve hypoplasia (ONH) as an early and congenital form of intrinsic axonal loss and Leber hereditary optic neuropathy (LHON) as a late and acquired form of intrinsic axonal loss. MATERIALS AND METHODS Optic nerves from 3 sources were examined: a 42-year-old healthy woman (control),...

Mutations in RAS, BRAF, PIK3CA, and TP53 are well-established genetic abnormalities metastatic colorectal cancer (mCRC). However, limited information is available for patients from Eastern Europe, including Romania. In this retrospective analysis, we investigated 104 mCRC the Northeastern region of Romania to determine frequency, distribution, coexistence, clinicopathological molecular correlat...
