among oral lesions, we encounter a series of malignant epithelial lesions that go through clinical and histopathologic processes in order to be diagnosed. identifying these processes along with the etiology knowledge of these lesions is very important in prevention and early treatments. dysplasia is the step preceding the formation of squamous cell carcinoma in lesions which have the potential ...

the current study was conducted in order to examine the effectiveness of shelf procedure in symptomatic adult patients due to hip dysplasia. this study is retrospective and was performed on patients who had undergone surgery by one orthopaedic surgical team during the past 20 years. twenty-three men and twenty-three women were enrolled in the study with a mean age of 29.3 years at the time of o...

a pulmonary embolus clogs the artery that provides blood supply to a part of the lung. the embolus not only prevents the exchange of oxygen and carbon dioxide but also decreases blood supply to the lung tissue itself, potentially causing the tissue to die (infarct). a 52-year-old man presented with syncope and anxiety. he had sinus tachycardia and dilated right ventricle with trabeculations. a ...

Ectodermal dysplasia is a heterogeneous hereditary disorder characterized by aplasia or dysplasia of tissues of ectodermal origin, such as skin, hair, teeth, and sweat glands and nails [1]. Ectodermal dysplasia syndrome was first described by Thurman in 1848 [2]. Although about 170 different subtypes of Ectodermal dysplasia have been recognized, these disorders are considered to be relatively r...

Case Description- Three female Pomeranian dogs with mean age about 1-year-old and history of seizure and sudden shock were referred to Small Animal Hospital of University of Tehran. Clinical Finding- Occipital Dysplasia was diagnosed by radiographic findings in rostrodorsal- coudoventral oblique view in all cases. Treatment and Outcome- These dogs recovered by 14 days administration of Glucoc...

PURPOSE There is controversy over the treatment for low grade dysplasia, while resection is recommended for high grade dysplasia. But the concordance of the grade of dysplasia between pre- and post-resection is low because of sampling errors with endoscopic biopsy. We attempted to establish a clearer direction for the treatment of dysplasia by clarifying the discrepancy between the pre- and pos...

AIM To clarify risk based upon segment length, diagnostic histological findings, patient age and year of surveillance, duration of surveillance and gender. METHODS Patients registered with the United Kingdom Barrett's Oesophagus Registry from 9 United Kingdom centers were included. The outcome measures were (1) development of all grades of dysplasia; (2) development of high-grade of dysplasia...

Dysplasia is linked to altered tissue architecture. The lesion belongs into the diagnostic field of human pathology and is highly relevant for the clinical physician, because it breaks the criteria of hyperplasia and regeneration. Dysplasia is a precancerous disorder leading in all probability to malignant transformation if not treated. However, different descriptions do apply for dysplasia in ...

Pathologic specimens, both biopsies and endoscopic mucosal resections, for Barrett esophagus and Barrett-associated dysplasia and malignancy are common for pathologists in North America, and the incidence in South Asian countries seems to be increasing. Dysplasia and malignancy arising in intestinalized gastric-type mucosa raises issues in the interpretation of dysplasia and the evaluation of t...

Ectodermal dysplasia is a rare entity with incidence of 1 in 1,00,000 births male predominance. Most commonly it presents appendageal abnormality facial dysmorphism. The two most common types ectodermal dysplasias are hypohidrotic (Christ-Siemens-Touraine syndrome) and hidrotic (Clouston syndrome). Clinical recognition varies depending on severity symptoms associated complications. prognosis go...
