Epignathus or oropharyngeal teratomas are extremely rare congenital neoplasms that arise from the oral cavity or pharynx. Teratomas commonly occur in sacrococcygeal region. However, less than 5% occur in the head and neck. Malignant teratomas account 5%-30% of all teratomas. We present an unusual case of immatureoropharyngeal teratoma that arises from sphenoid with intracranial extension, in a ...

A retrospective cohort study was conducted to determine the 5-year survival and prognostic factors for survival for 407 oropharyngeal cancer cases registered in the 3 main hospitals in Alexandria, Egypt, from 1996-2000. Survival analysis was conducted using Kaplan-Meier curves, and multivariate Cox regression analysis. The overall 5-year survival rate was 30.8%. Multivariate analysis showed tha...

Two further points of surgical anatomy require emphasis. First, some authors include the retromolar trigone as part of the oropharynx while others do not. The retromolar trigone is included in the oral cavity in the UICC/AJC (Union Internationale Contre Le Cancer/American Joint Committee) definition, and tumours of the trigone should not be considered as oropharyngeal tumours. Second, tumours o...

Squamous cell carcinoma (SCC) of the oral cavity and pharynx represents the sixth most common form of malignancy worldwide. A significant proportion of these cases are related to human papillomavirus (HPV) infection. In general, HPV-associated SCC is more commonly nonkeratinizing and poorly differentiated, whereas non-HPV-associated SCC is typically keratinizing and moderately differentiated. N...

A patient developed dysgonic fermenter-2 (DF-2) septicaemia and meningitis after having been bitten by a dog. The pathogenic organism was isolated from the oral cavity of the dog, which, it is believed, is the first time that this has been done. The growth characteristics of the organism and the immunological response of the patient were studied. The isolation of the infecting agent from the do...

Squamous cell carcinoma of the head and neck (SCCHN) is the sixth most common cancer worldwide. The main risk factors for cancers of the oral cavity, larynx, oropharynx, and hypopharynx are alcohol and tobacco use. In addition, the human papillomavirus (HPV) is an established cause of oropharyngeal cancer. An experienced multidisciplinary team is necessary for adequate management and optimal ou...

n estimated 644,000 cases of head and neck cancer are diagnosed worldwide each year, with head and neck squamous cell carcinoma (HNSCC) accounting for over 90% of these. Common presenting sites include the oral cavity, oropharynx, nasopharynx, hypopharynx, and larynx.1 While chronic tobacco use and alcohol consumption are well-established risk factors,2 human papillomavirus (HPV) infection of t...

A patient with severe toxic epidermal necrolysis underwent 2 cycles of therapeutic plasma exchange and received specialized wound care for widespread skin damage of more than 80% of his body surface area. Extensive involvement of mucous membranes, including the conjunctivas and the oropharyngeal cavity, and damage of his genitourinary organs required meticulous wound care. Daily care of injurie...

Head and neck cancer (HNC) is defined as malignant tumours located in the upper aerodigestive tract and represents 5% of oncologic cases in adults in Spain. More than 90% of these tumours have squamous histology. In an effort to incorporate evidence obtained since 2013 publication, Spanish Society of Medical Oncology (SEOM) presents an update of HNC diagnosis and treatment guideline. The eighth...

Oral Tuberculosis is a rare disease, accounting for less than 1% of all cases of tuberculosis. The most common manifestation is a non healing ulcerative lesion of the mucosa which is often misdiagnosed. The recent increase in the incidence of tuberculosis especially after the advent of HIV infection, combined with an emerging global resistance to anti-tuberculous drugs, warrants an increased aw...
