ABSTRACT: Intraneural perineurioma or reticular perineurioma, which is 1 variant of extraneural perineurioma, has been rarely reported in the head and neck region.
We report a case of a 52-year-old woman who wasseen with a swelling in the neck. A mass was found located on the medial aspect of the left submandibular gland and was palpated with a sponge-like texture. The mass was seen as a homogenous semisolid lesion on CT and ultrasound examination.
Surgical exploration revealed expansion of the hypoglossal nerve. Microscopically, the tumor showed both pseudo-onion bulb, which is a feature of intraneural perineurioma, and reticular pattern with microcysts, which is a feature of reticular variant of extraneural perineurioma. The tumor cells were immunopositive for epithelial membrane antigen and human erythrocyte glucose transporter-1 (GLUT-1).
An intraneural reticular perineurioma of the hypoglossal nerve should be included in the differential diagnosis of submandibular swelling.

ABSTRACT: Foregut duplication cysts of the hypopharynx are extremely rare, and only 6 cases, all of which have been described as solid lesions and contained heterotopic gastric epithelium, could be found during our literature review. We present a unique case of a hypopharyngeal foregut duplication cyst that was grossly cystic and had no heterotopic epithelium microscopically. The present case required intubation for stridor and airway obstruction shortly after birth. Congenital laryngeal cysts can appear similar to this lesion. However, the hypopharyngeal location of a cyst is a clue for the diagnosis of duplication on endoscopic examination.

ABSTRACT: To assess the effectiveness of intraoral removal of submandibular calculi based on several factors that may influence the results of surgery.
We retrospectively reviewed 172 patients who underwent intraoral removal of submandibular sialolithiasis. Results of surgery were divided into complete removal, partial removal, and failure. The effect of location, palpability, size, and presence of infection of the calculi on the results was estimated.
Univariate analysis showed that palpability and presence of infection were statistically significant factors affecting intraoral removal. Palpability was the only significant factor after multivariate analysis. Twelve of 13 patients with recurrent calculi underwent repeat intraoral removal successfully.
The palpability of submandibular calculi is the most important factor influencing their successful intraoral removal.
Intraoral removal can be performed successfully regardless of location, size, presence of infection, or recurrence of calculi, if the calculi are palpable.
