We reviewed clinical manifestation of 12 patients from three Korean families. They showed mild to moderate bone fragility, and suggested an autosomal dominant inheritance pattern. Significant intrafamilial phenotype variability was obvious. Clinical, radiological, and histopathologic characteristics that distinguished this subtype from others include ossification of interosseous membrane of the...

Odontogenic cysts and tumors originate from remnants of odontogenic epithelium and have a wide spectrum of histopathologic and clinical characteristics, ranging from benign non-invasive to locally invasive or malignant lesions. Histopathologic similarities between these lesions may challenge the correct diagnosis, especially in small size specimens, and may also lead to unnecessary broad surger...

Sarcomatoid carcinoma (SC) is a rare variant of squamous cell carcinoma which is characterized by a dysplastic epithelial component and a stromal element with invasive fusiform or spindle-shaped cells. The clinical and histopathologic characteristics make it very difficult to distinguish SC from epithelioid sarcoma (ES). We present a case of a 51-year-old man with a soft tissue mass in the oral...

Objective: Neuronal and Mixed Neuronal-glial Tumors of the Central Nervous System are frequently encountered in the neurosurgical practice. Differentiation of neuronal tumors from the more common glial tumors is crucial because neuronal tumors have favorable clinical outcomes and are generally curable with total surgical resection alone, whereas gliomas typically require further chemoradiothera...

introduction: the aim of this study was to identify the reasons for failure in clinical, radiographic, and histopathologic diagnoses as well as their interactions with each other. methods: personal information and lesion characteristics of 51 patients with central or peripheral exophytic lesions were collected in mashhad dental school. specialists determined clinical and radiographic diagnoses ...

Aim of this study was to investigate the correlation of matrix metalloproteinase-9 (MMP-9) expression with histopathologic and clinical characteristics of laryngeal squamous cell carcinoma, and to assess the role of MMP-9 expression in patient survival. Study included 196 patients with squamous cell carcinoma of the larynx treated at ENT Department, Split University Hospital Centre, from Januar...

at necropsy of a five-year-old sheep, a pear shaped, lobular yellow-brownish mass measuring about 12 ×15 × 20 cm was found to involve the right hepatic lobe. microscopic examination revealed two trabecularand solid patterns of neoplastic hepatocytes. in solid pattern, there were numerous tumoral giant cells thatcontain one or more large hyperchromatic bizarre-shaped nuclei scattered among clust...

henoch-schönlein purpura nephritis and iga nephropathy are currently considered to be different clinical presentations of the same disease. there is need for a reliable proven, morphologic classification that can help clinicians more accurately formulate treatment strategies for patients with henoch-schönlein purpura nephritis. considering that henoch-schönlein purpura nephritis and iga nephrop...
