paragangliomas in the head and neck are found typically in the region of the carotid body, jugular body, and along the 9th and 10th cranial nerves. they can occur in multicenteric forms, but generally, laryngeal paragangliomas are not found in these patients. only two cases of laryngeal paraganglioma have been reported with a synchronous lesion elsewhere. we report an additional case of a 34-ye...

The characteristics of synchronous and subsequent lesions of serrated adenomas (SAs) of the colorectum are still unclear. This study aimed to clarify the characteristics of synchronous and subsequent lesions of SAs compared with tubular adenomas (TAs) of the colorectum. Patients were divided into 2 groups: SA (127 patients) and TA (158 patients). The mean follow-up durations in the SA and TA gr...

AIM few data have been published regarding the causes of synchronous lesions in patients with colorectal cancer. The aim of our study was to identify potential factors that might be implicated in the development of multicentric lesions, since this knowledge could be useful for tailored follow-up once initial synchronous lesions have been removed. METHODS we retrospectively reviewed 382 colore...

Endoscopic resection is now established as a standard treatment for gastric epithelial neoplasms such as early gastric cancer and adenoma. Careful preprocedural evaluation and proper patient selection are important for successful therapeutic outcomes; therefore, repeated endoscopy is often planned when a patient is referred, and a more detailed examination is thought to be necessary for decidin...

OBJECTIVE Laryngomalacia is the most common cause of congenital stridor. Laryngomalacia may be associated with other structural and functional airway lesions. While previous studies suggested a 10-45% rate of synchronous airway lesions (SALs), the exact rate and it's clinical significance is unknown. The purpose of this study was to determine the prevalence of SALs below the glottic level in co...

Twenty-one cases of malignant gliomas showing multiple tumor foci on CT are described. In 11 patients multiple lesions were evident on the initial CT scan (synchronous lesions); the other 10 patients developed one or more lesions months to years after the original gliomas (metachronous lesions) were documented. Distinctions between multifocal and multicentric gliomas are discussed and CT patter...

Synchronous colorectal carcinoma defines as multiple malignant lesions presented in a single patient at initial diagnosis. We report a case of triple synchronous colorectal carcinoma without related familial history. Preoperative computed tomography (CT) scan and endoscopic examination suggested multiple malignant lesions occurred in separate segments of colon. Then we performed laparoscopic to...

OBJECTIVE To determine the prevalence of synchronous airway lesions and esophagitis in children younger than 18 months undergoing adenoidectomy for adenoid hypertrophy and upper airway obstruction. DESIGN Retrospective review spanning 4.5 years. SETTING Tertiary care children's hospital. PATIENTS All children younger than 18 months who underwent adenoidectomy for upper airway obstruction ...
