Tongue Base Schwannoma.

Intraoral schwannomas account for 1% of head and neck schwannoma, with tongue base schwannoma being reported rarely. In an English literature search from 1988 to 2014, not more than 38 cases of tongue base schwannoma have been reported. Large tongue base schwannomas pose a significant risk to airway, thereby calling for an early intervention. We report a rare case of tongue base schwannoma in a 25 year old female managed surgically by lateral pharyngotomy approach.

An Unusual Cause of Postaural Swelling: Kimura's Disease.

INTRODUCTION: Kimura's disease (KD) is an allergic inflammatory disorder of unknown etiology endemic in Orientals. Kimura's disease was first mentioned by Kimm and Szeto in China in 1937. Kimura's disease is commonly encountered in Asia and is mostly reported in Japan, China, Singapore and Honkong. However, only a few cases have been reported in the Indian subcontinent. CASE REPORT: A case of Kimura's disease in a young male managed by surgery is reported in addition to a literature review. CONCLUSION: Diagnosis is made on the basis of histopathological analysis, clinical presentation, and laboratory investigations. Long term follow-up is required as Kimura's disease is prone for recurrence.

Use of Intrathecal Fluorescein in Recurrent Meningitis after Cochlear Implantation.

INTRODUCTION: Congenital anomalies of the cochlea and labyrinth can be associated with meningitis and varying degrees of hearing loss or deafness. Despite antibiotics, meningitis remains a life threatening complication. CASE REPORT: We report a case of recurrent meningitis following episodes of otitis media in a cochlear implantee child with bilateral vestibulocochlear malformation, due to fistula in the stapes footplate. Intrathecal fluorescin was used to identify the leak site. CONCLUSION: Recurrent meningitis can indicate for possible immunological or anatomical abnormalities as well for chronic parameningeal infections. Intraoperative use of intrathecal fluorescin is an ideal investigative tool to demonstrate cerebrospinal fluid (CSF) leak site in patients in whom other investigations fail to do so.

Extragonadal primary yolk sac tumour of temporal bone.

Yolk sac tumour, also known as endodermal sinus tumour (EST) is malignant germ cell tumours usually seen in children less than 3 years of age, involving the testis. We describe a rare case of extragonadal primary yolk sac tumour of the temporal bone in a 2.5 years old child presenting with a left sided post auricular mass and facial nerve palsy. Biopsy was consistent with yolk sac tumour showing expression of alpha fetoprotein. Patient was treated with chemotherapy including cisplatin, etoposide, and bleomycin. Post chemotherapy there was decrease in the swelling with improvement in facial nerve palsy.
