The histologic and enzyme histochemical characteristics of chronically denervated dog extraocular muscle (EOM) were studied. Our results show atrophy of coarse and granular fibers, with relative sparing of fine fibers. Thus experimentally denervated EOM does not demonstrate the familiar changes of denervated limb muscle but shows prominent atrophy of two of the three EOM fiber types. (INVEST OP...

the most frequent form of inflammatory bowel disease (ibd) in dogs is represented, histologically, by lymphoplasmacytic enteritis (lpe), a histological category, often associated with other morphologic alterations including lymphangiectasia (le). however, literature data on this latter topic are quite scarce and have mostly been obtained in single reports or in small series. currently, there ar...

abstract   background : although, different studies on end-to-side nerve repair, results are controversial. the importance of this method in case is unavailability of proximal nerve. in this method, donor nerves also remain intact and without injury. in compare to other classic procedures, end-to-side repair is not much time consuming and needs less dissection. overall, the previous studies in ...

OBJECTIVE The histologic types of borderline ovarian tumors (BOTs) exhibit striking differences in clinical behavior and prognosis. Yet, there is no information available on the histologic distribution of BOTs according to geographic region. The purpose of this study was to systematically review this issue worldwide. METHODS A comprehensive search of the literature was conducted using electro...

BACKGROUND AND PURPOSE ADCs may help distinguish benign from malignant head and neck diseases. We sought to evaluate the effectiveness of ADC for differentiating between carcinomas and lymphomas of the nasopharynx and oropharynx. MATERIALS AND METHODS We retrospectively compared the ADCs between 24 histologically proved lymphomas and 32 carcinomas, including 8 NPCs and 7 lymphomas of the naso...

malignant fibrous histiocytoma (mfh) is the most common soft-tissue sarcoma which predominantly surfaces in the retro-peritoneum and extremity. mfh of lung is a very rare condition. the diagnosis is essentially through histologic examination. however, the invasion of the chest wall or other organs might help establish the malignant nature.we report a case of a 77-year-old man who had been prese...

biopsies of thoracic lesions guidance. 22 of the 1 12 lesions were mediastinal and 83 were pleuroparenchymal. a large-bore 14-gauge tru-cut needle was used in all patients. adequate specimens for histologic examination were obtained in 98%. the overall accuracy was 91 % with 9% false negative and no false positive diagnoses. despite the large size of the needle, the total number of complication...

PURPOSE Human epidermal growth factor receptor 2 (HER2)-positive luminal B type comprises estrogen receptor (ER)-positive and HER2-positive cancers, and HER2-negative luminal B type comprises ER-positive cancers showing a Ki-67 labeling index ≥14% or progesterone receptor (PR) expression of <20% according to the St. Gallen consensus 2013. The current study aimed to classify intrinsic subtypes a...

The analysis is based on the records antI flludimugs in a gIo)tup of 437 white muales in whoni Hodgkin’s disease was first diagnosed in Army hospitals during the World War II period of service (1941-1946). Included are all cases answering this description and entered in the Lym )hatic Tuunor Registry of the Armed Forces Itustitute of Pathology. The ages of the patients at the time of diagnosis ...
