Sinobronchial allergic mycosis syndrome in an elderly male.

Background: Allergic bronchopulmonary aspergillosis (ABPA) and allergic fungal rhinosinusitis (AFRS) are characterized by hyper-responsiveness of the respiratory tract and the nasal cavity and paranasal sinuses, respectively to species and AFRS causes chronic rhinosinusitis. Herein, we report the first case of sinobronchial allergic mycosis (SAM) syndrome, defined as ABPA with concomitant AFRS, caused by patient > 80 years.

Case Presentation: An 82-year-old male with interstitial pneumonia who returned for follow-up exhibited high-attenuation mucus plug in the right intermediate bronchial trunk, infiltration in the right lung field, and right pleural effusion on regular chest computed tomography (CT).

Melanotic oncocytic metaplasia of the nasopharynx: a case report with a focus on immunohistochemical analyses and literature review.

Melanotic oncocytic metaplasia (MOM) of the nasopharynx is an extremely rare lesion, with only 21 cases reported in English literature to date. MOM typically occurs near the Eustachian tube opening in Asian men in their 60 s to 70 s. Here, we present a case of MOM in a 57-year-old Japanese man who is a heavy smoker.

Ewing's sarcoma family of tumors of the maxillary sinus: a case report of multidisciplinary examination enabling prompt diagnosis.

There have been approximately 10 reports in English literature of cases of Ewing's sarcoma family of tumors (EFT) arising in the maxillary sinus. In this location, some tumors mimic EFT, and are more frequently encountered. Herein, we present an additional case of an EFT originating in the maxillary sinus.

Transoral closure of pharyngeal perforation caused by gastrointestinal endoscopy.

Objective: We present a case of pharyngeal perforation caused by gastrointestinal endoscopy that was successfully repaired with transoral mucosal sutures. This is the first report of a transoral surgical closure of a perforation caused by an endoscope. We describe the repair procedure, the necessary equipment, and the effectiveness of suturing pharyngeal perforations.

Selective reconstructive options for the anterior skull base.

Carcinomas of the ethmoid, frontal, or maxillary sinuses sometimes invade the anterior skull base. It is necessary to perform en-bloc resection for this invasive carcinoma according to the concepts of surgical treatment for head and neck cancer. The anterior skull base consists of two parts, the orbital roof as the lateral portion and the roofs of the frontal sinus, ethmoid sinus, and/or sphenoid sinus as the central portion.

Intramucosal PCO2 measurement as a new monitoring method of free jejunal transfer following pharyngo-laryngo-esophagectomy.

The choices for practical monitoring of free jejunal transfer have been quite limited because of its own characteristics, such as buried form, lack of skin surface, and the structure of a hollow viscous tract. Physiologically, it is known that tissue hypoxia caused by compromised perfusion leads to an increase of partial pressure of carbon dioxide (PCO2). Because of its physiological properties, the diffusion of carbon dioxide is always equilibrated between the mucosa of a hollow viscous organ and its lumen.
