Case of submandibular schwannoma and review of literature.

Schwannomas are slow growing, benign tumours arising from Schwann cells. They are usually solitary and are sometimes associated with Neurofibromatosis type 1 and 2. As reported by Okada et al.

Clinicopathologic Examination of Translucent Refractile Intraluminal Tissue Coagulum From the Proximal Tube of a Baerveldt Glaucoma Drainage Device.

Purpose: To describe an unusual case of glaucoma drainage tube blockage.

Patients: A 76-year-old woman presented with left endothelial graft failure. Her previous ocular history included primary open-angle glaucoma diagnosed for 15 years and Fuch's endothelial dystrophy.

Adult Orbital and Adnexal Xanthogranulomatous Disease.

Purpose: Adult xanthogranulomatous disease of the orbit and ocular adnexa is a rare disease that can cause serious morbidity and mortality. Ophthalmologists are commonly the first clinicians to come in contact with affected patients and an understanding of the clinical features is essential.

Design: We present a retrospective case series of patients seen in the oculoplastic unit of a large tertiary referral hospital over a 20-year period.

Expression profiling of cutaneous squamous cell carcinoma with perineural invasion implicates the p53 pathway in the process.

Squamous cell carcinoma (SCC) is the second most common cancer worldwide and accounts for approximately 30% of all keratinocyte cancers. The vast majority of cutaneous SCCs of the head and neck (cSCCHN) are readily curable with surgery and/or radiotherapy unless high-risk features are present. Perineural invasion (PNI) is recognized as one of these high-risk features.

Fatal epiglottic abscess after radiotherapy for laryngeal carcinoma.

Acute epiglottitis is a rare condition, especially in adults, largely owing to the widespread vaccination against Haemophilus influenzae. Traumatic epiglottitis as a result of thermal or caustic insults is documented. Epiglottic abscess formation is described as a sequela of epiglottitis in some cases.
