Mycobacterial tuberculosis superimposed on a Warthin tumor.

The concomitant occurrence of tuberculosis infection within a Warthin tumor is extremely rare, as only 6 cases have been previously reported in the English-language literature. We report a new case in a 92-year-old man, who presented with a 20-year history of a painless swelling in the right infra-auricular area that had recently become painful and larger. The patient had no history of tuberculosis, weight loss, or chronic cough.

Gold nanoparticles as high-resolution X-ray imaging contrast agents for the analysis of tumor-related micro-vasculature.

Background: Angiogenesis is widely investigated in conjunction with cancer development, in particular because of the possibility of early stage detection and of new therapeutic strategies. However, such studies are negatively affected by the limitations of imaging techniques in the detection of microscopic blood vessels (diameter 3-5 μm) grown under angiogenic stress. We report that synchrotron-based X-ray imaging techniques with very high spatial resolution can overcome this obstacle, provided that suitable contrast agents are used.

Subglottic cyst: the role of narrow-band imaging.

A subglottic cyst is a rare cause of neonatal upper airway obstruction, which may be misinterpreted as a subglottic hemangioma. With the advent of narrow-band imaging, the application of its unique features in analyzing the mucosa surface's vascular structures in pediatric subglottic lesions remains to be investigated. Here, we report the case of a preterm baby who developed two subglottic cysts when he was 3-months old.

Otomastoiditis with acute left facial nerve paralysis caused by Mycobacterium chelonae.

Mycobacterium chelonae usually causes soft-tissue and skin infection. It is a rare cause of otomastoiditis. The clinical presentation and operative findings are similar to those of other nontuberculous mycobacterial infections.

Brainstem hemorrhage presented as audiovestibular syndromes.

Brainstem hemorrhage usually presented with acute multiple neurologic dysfunction, and the prognosis was poor. Rarely, it can manifest with audiovestibular symptoms only. Here, we report a case of brainstem hemorrhage involving the right middle cerebellar peduncle and dorsal lateral pons presented with constant nonpulsatile tinnitus and rotatory vertigo.

Voice and speech outcomes with radial forearm free flap-accompanied phonation tube after total pharyngolaryngectomy of hypopharyngeal cancer.

Conclusions: Radial forearm free flap (RFFF)-accompanied phonation tube (PT) for voice and speech restoration after pharyngolaryngectomy is promising, especially in phonation efficacy and intelligibility. It offers not only another safe surgical option but also a satisfactory result for such patients with advanced hypopharyngeal cancer.

Objectives: We use RFFF with RFFF-accompanied PT for one-stage reconstruction both for tissue defect and voice reconstruction in patients undergoing total pharyngolaryngectomy.

Cholesterol granuloma of the external ear canal: A rare presentation.

Almost all aural cholesterol granulomas develop in the mucosa of the middle ear. We describe the case of a 14-year-old girl who presented with an asymptomatic, nontender, dark-blue, cystic lesion in the posteroinferior portion of the left ear canal. The mass was excised via a postauricular approach.
