[Heterotopic brain tissue in the pharynx].

The presence of heterotopic brain tissue in the head and neck region is exceptional. Most reported cases have been observed in the nasal region and are called nasal gliomas. The case of a 10-month-old boy with heterotopic brain tissue on the soft palate and nasopharynx is reported. Surgical treatment was successful and no complications or recurrences have been observed in 7 years of follow-up. The main pathogenic theories and nomenclature are analyzed.

[Naso-alveolar cysts. A report of 10 new cases and a review of the literature].

Nasoalveolar cysts, also known as Klestadt's or nasolabial cysts, are uncommon midfacial lesions. Ten cases treated at the 12 de Octubre University Hospital are reported, describing the most relevant clinical and pathological findings are reported. The main theories of the origin of these developmental, non-odontogenic cysts are discussed. A review of the literature is included.

[Primary nasal sinus malignant melanomas].

Primary malignant melanoma of the mucosa of the nasal and paranasal sinuses is rare, difficult to treat, and usually has a poor prognosis. Seven cases, six women and one man (mean age 76.5 years), were treated at the Hospital 12 de Octubre (Madrid, Spain) during the period 1982-1994. The presenting symptoms, diagnostic evaluation, morphology, therapeutic modalities, histological evaluation, and clinical course were reviewed. Three patients were treated surgically and three received palliative irradiation. All had local recurrence or distant metasfases within 15 months after concluding treatment. The seventh patient refused treatment.

[Thyroid nodules: factors suggestive of malignancy].

The evaluation and management of thyroid nodules is a common problem in medicine. In a review of 250 cases of thyroid disease seen at the 12 de Octubre Hospital (Madrid, Spain), 191 cases of solitary nodules and multinodular goiter were analyzed. The clinical findings, complementary studies, and postoperative histology were analyzed to determine the parameters most closely related to malignant thyroid processes. The overall rate of malignancy was 22.5%. Major clinical factors associated with malignancy were fixation to deep structures, cervical lymph node enlargement, and paralysis of the vocal cords. None of the complementary tests was absolutely reliable in excluding malignancy, but fine needle aspiration biopsy, in spite of its limitations, was the best diagnostic tool. Surgery is indicated if the benignity of a nodule cannot be confirmed.

[Prognostic factors in pediatric myringoplasty. A review of 90 cases].

Although tympanic membrane perforations continue to be a significant source of otologic morbidity in the pediatric population, myringoplasty in children still elicits debate. The records of 76 patients under 18 who underwent 90 myringoplasties at the 12 de Octubre University Hospital (Madrid, Spain) over a recent 8-year period were reviewed. The overall short-term surgical success rate was 64.8%. The overall success rate evaluated at least one year after surgery was 58%. The audiological threshold improved in 68% per cent of successful cases. Surprisingly, females had lower graft take rates than males. The outcome of surgery was unrelated to age at operation, duration, mechanism, size, and location of the perforation, or condition of the opposite ear.

[Granular cell tumor: an infrequent cause of dysphonia in childhood].

Granular cell tumors (GCT) are rare and usually benign tumors whose histogenesis is debated. The skin, subcutaneous tissues, and mucosae of the head and neck are areas of predilection for GCT. Laryngeal involvement is uncommon, but may create diagnostic and therapeutic problems when it occurs. Laryngeal GCT are decidedly uncommon in children, only 17 cases having been reported in the literature. A case of GCT of the larynx in an 11-year-old girl is reported. The presenting symptom was hoarseness. The macroscopic tumor and hoarseness disappeared after chemotherapy (EVAIA) for Ewing sarcoma of the knee.

[Lingual abscess with atypical clinical presentation].

Lingual abscesses have become extremely rare since the discovery of antibiotics, with only about 200 cases reported in the last 160 years. Diagnosis on the basis of clinical symptoms alone is quite difficult. Imaging studies are essential for the diagnosis of lingual abscesses and for their differentiation from related pathologies with similar clinical symptoms. We report a case of lingual abscess with otherwise unremarkable clinical findings that was diagnosed by CT scan. The etiology, pathophysiology, bacteriology, diagnosis, and treatment of these uncommon infections is discussed.

[Branchial cysts with heterotopic salivary tissue in the upper third of the neck].

The presence of heterotopic salivary gland tissue (HSGT) in rather uncommon in the neck. Usually it has been located in its lower third. HSGT in the upper neck is believed to be a rare entity. Two cases of HSGT in the upper neck are presented, with a review of their clinical and histopathological characteristics. The embryologic derivation of salivary tissue and close association with the branchial apparatus are discussed. The possibility of neoplastic transformation must always be considered in these uncommon lesions.
