Squamous cell carcinoma temporal bone (SCCTB) is a rare malignancy with incidence of around 1 to 1.2 case per million populations per year. Risk factors included chronic otitis media and chronic irritation of the skin and mucosa of the external and middle ear. A rare but important aetoloigy is radiation to the region for treatment of head and neck malignancies. This article is protected by copyright. All rights reserved.

Gorlin-Goltz syndrome (GGS) is a rare genetic syndrome with variable expressivity and autosomal dominant inheritance. The major features of GGS include numerous basal cell carcinomas (BCCs), keratocysts of the jaw, palmar/plantar pits and calcification of the falx cerebri. Authors report the case of a 51-year-old male with a 19-year history of GGS and multiple BCCs of the head and neck. He presented with a large ulcerating lesion on the right side of his face involving cutaneous, subcutaneous and muscular tissues of the temporal and orbital region...

Metastatic renal cell carcinoma (RCC) involving the temporal bone is a rare entity. It is usually asymptomatic and misdiagnosis as acute otitis media, mastoiditis, and Ramsay-Hunt syndrome in early onset is not uncommon. We report a case of RCC metastasis to the postoperative temporal bone in the middle of molecular targeted therapy. A 60-year-old man presented left facial palsy with severe retro-auricular pain and he also underwent left middle ear surgery for cholesteatoma more than 30 years before and had been aware of discontinuous otorrhea; therefore, initially we speculated that facial palsy was derived from recurrent cholesteatoma or Ramsay-Hunt syndrome...

A modified lateral temporal bone resection (mLTBR) is a unique technique that spares the tympanic membrane (TM) and ossicles in select patients with squamous cell carcinoma (SCCa). The records of 5 patients with SCCa of the temporal bone with negative frozen-section biopsy at the tympanic annulus were reviewed. The mean follow-up time for the patients was 29.2 months. One patient received postoperative radiation due to cervical nodal extracapsular spread. All patients were recurrence free as of the most recent follow-up (range, 8-50 months)...

Cholesteatoma is a well demarcated, non-neoplastic, temporal bone cystic lesion with extensive keratinisation. Keratoma and epidermoid cyst are other possibly more accurate names suggested to describe the same. It can be classified as congenital or acquired. Its management is often complicated by its tendency to recidivism/recurrence. Long standing cholesteatomas can be a precursor for squamous cell carcinoma. We hereby present a case of giant cholesteatoma in a 45-year-old female with radiological involvement of the left temporal region, periauricular region and infratemporal fossa with lytic destruction of left middle ear ossicles, mastoid and squamous part of temporal bone with intracranial extension...

Squamous cell carcinoma of the temporal bone is a rare and destructive malignancy and represents both diagnostic and therapeutic challenge. The complex regional anatomy of the temporal bone requires equally intricate surgical techniques to adequately resect the tumour mass during surgical excision. Adjuvant radiotherapy is offered to patients with advanced disease and has been showed to confer a survival benefit in carefully selected patients. One feared complication of radiotherapy is osteoradionecrosis and is a major obstacle faced in the treatment of head and neck cancers...

PURPOSE: Cortactin is a multidomain protein engaged in several cellular mechanisms involving actin assembly and cytoskeletal arrangement. Cortactin overexpression in several malignancies has been associated with increased cell migration, invasion, and metastatic potential. Cortactin needs to be activated by tyrosine or serine/threonine phosphorylation. The role of cortactin and phosphorylated cortactin (residue tyr(466)) was investigated in temporal bone squamous cell carcinoma (TBSCC)...

Carcinoma in the external auditory canal (EAC) is a rare malignancy with an annual incidence of one per one million people, accounting for less than 0.2% of all head and neck cancers. The most common histopathological type of EAC cancer is squamous cell carcinoma. Verrucous carcinoma is a well-differentiated, low-grade variant of squamous cell carcinoma. It is a locally destructive, invasive, and slow growing tumor that rarely metastasizes. Verrucous carcinoma occurs predominantly in the oral cavity and larynx, and its occurrence in the EAC is extremely rare...
