[Tuberculous arthritis of the temporomandibular joint caused by Mycobacterium bovis. A diagnostic conundrum].

Infrequent variants of extrapulmonary tuberculosis pose a challenging public health problem because of the delay in their diagnosis and treatment. Joint involvement is usually encountered in major joints (hip, elbow, knee and ankle). Tuberculous involvement of the temporomandibular joint is extremely uncommon but must be considered in patients with pain, inflammation or joint stiffness not resolved with conventional treatment.

[Clinical study on head and neck tulareamia].

Objective: To perform a clinical description of head and neck tularaemia, collating the therapeutic strategies used and the most significant variables that seem to influence its evolution.

Material And Methods: A retrospective descriptive study was performed on the series diagnosed in 2007 with involvement of the head and neck areas. For the definition of clinical cases, the recommendations of the Spanish National Centre for Epidemiological Surveillance, the European Union Network for the Surveillance and Control of Communicable Diseases and the U.

[Fast-growing atypical cervical mass].

Aneurysms of the jugular vein are an uncommon condition, typical of childhood and adolescence although they can appear at any age. Clinically, they normally constitute an asymptomatic cervical mass which increases when Valsalva's manoeuvre is applied. Doppler echography is the most effective diagnostic test, with CT or NMR for doubtful situations.

[Castleman's disease of the neck].

Castleman's disease is an uncommon benign lymphoid disorder usually found in the mediastinum (70 %) which is thought to be due to antigenic hyperstimulation of unknown origin. Two histological subtypes may be found in relation to two different clinical patterns with clinical and therapeutic implications. Diagnosis is frequently accomplished only by histological analysis after surgery since no specific features have been found in imaging studies.

[Synchronous ENT lymphoepitheliomas. Controversies on their diagnosis and treatment].

Lymphoepithelial carcinomas are characterized by proliferation of undifferentiated malignant epithelial cells together with an infiltrate of mature lymphocytes. They mainly appear in the nasopharynx but can also be encountered in other upper and lower aerodigestive sites such as oropharynx, stomach, trachea, and others. When they occur in the larynx they usually do so in the laryngeal ventricle and are characterized by protrusion of the laryngeal band, visible in laryngoscopy.

[Clinical picture of 8th pair schwannoma. Is it expressive enough?].

Objective: To describe the stage-related clinical features of 8th cranial nerve schwannoma.

Material And Method: Descriptive study of 71 patients whose diagnosis and/or treatment have been carried out at our centre between 1997-2003. Gender, age, and symptoms were considered, with special attention to gender.
