Castleman's disease is a rare lymphoproliferative disorder that is easily misdiagnosed. When it occurs in the head/neck and thorax, it can pose a diagnostic dilemma because of its lack of any specific presenting characteristics and distinguishing radiographic features. An accurate histopathologic diagnosis and careful staging are crucial to planning treatment. The highly vascular nature of the ...

BACKGROUND AND PURPOSE Our hypothesis was that the carotid plaques associated with retinal and cerebrovascular symptomatology and asymptomatic presentation may be differ from each other. The aim of this study was to identify the sonographic and histopathologic characteristics of plaques that corresponded to these three clinical manifestations. METHODS The echo process involved duplex preopera...

OBJECTIVES/HYPOTHESIS Treatment of cutaneous melanoma involves surgical excision with wide clinical margins. No guidelines regarding safe histopathologic margin distance exist. This study examines the impact of histopathologic margin, measured from closest cut edge of the specimen, on overall survival in resection of cutaneous melanoma of the head and neck. We hypothesize that close histopathol...

The purpose of our study is to analyze the clinical, ultrasonic, microbiologic, and histopathologic characteristics, management, and outcomes in a series of primary canaliculitis with concretions patients who underwent canaliculotomy with curettage.Thirty-six patients were reviewed for age, sex, location and laterality, duration of symptoms, clinical symptoms, ultrasonic signs, result of microb...

major salivary gland tumors are uncommon and the exact nature of these tumors is not obvious. this study was carried out to compare the histological results of intraoperative frozen sections against those of permanent reports for major salivary glands masses. one hundred thirty-nine patients with major salivary gland masses who were candidates for surgery underwent an intraoperative frozen sect...
