[Giant antro-choanal polyp]. / Pólipo antrocoanal gigante.

Antrochoanal polyps are, basically, pathologies of children and young adults. The case here reported is really exceptional because its size and its appearance at so unusual age. Etio-pathogenesis, clinical course and differential diagnosis, face to other pathologies, are perused and also with several varieties of choanal polyps and the treatments proposed as well.

[Leiomyoblastoma of the tongue]. / Leiomioblastoma lingual.

Leiomyoma is a benign tumor of smooth muscle origin that is rarely found in oral cavity. We report a case of leiomyoblastoma of the tongue. The interest of this lesion is supported by its location and by the difficulty to determine its biological behavior. About 25% of the oral smooth muscle tumors are malignant, and have been reported "leiomyoma" locally invasive.

Leiomioblastomal lingual / Leiomioma smooth muscle

Presentamos un caso de leiomioblastoma lingual y, a partir de él, describimos los leiomiomas orales, tumores benignos que se originan en el músculo liso y cuya localización en la cavidad oral es muy rara. El interés de estos tumores no sólo estriba en la rareza de su lugar de asiento, sino también en la dificultad que existe para definir subenignidad y comportamiento biológico. El 25 por ciento de los tumores de músculo liso orales son malignos, y han sido descritos "leiomiomas" localmente invasivos (AU)

Leiomyoma is a benign tumor of smooth muscle origin that is rarely found in oral cavity. We report a case of leiomyoblastoma of the tongue. The interest of this lesion is supported by its location and by the difficulty to determine its biological behavior.

[Tracheocele: a case report]. / Traqueocele Presentación de un caso.

Report of one tracheocele case casually uncovered in a man 51-year-old. Starting from the difference between congenital and acquired cases of this pathology the AA. refer to the symptomatologic picture, to diagnostical and therapeutical measures as well, pinpointing to possible complications that may arise specially by infants during the lactation period.

[Dural arteriovenous fistula of the lateral sinus: origin of objective tinnitus]. / Fístula arteriovenosa dural del seno lateral: origen de acúfenos objetivos.

Objective tinnitus usually has a vascular origin, but dural arteriovenous fistulas are rarely the cause of this sign. We report a case of arteriovenous meningeal fistula (AVMF) of the lateral sinus, origin of pulsatile objective tinnitus. Etiology, pathophysiology, symptoms, diagnosis, differential diagnosis and treatment of these fistulas are reviewed.

[Mixed tumor in cervical salivary heterotopy]. / Tumor mixto en heterotopia salival cervical.

This paper presents a case, infrequent and clinically unsuspected, of pleomorphic adenoma in the upper region of the neck in front of the sternocleidomastoid, independent of the salivary glands. The tumor developed within an heterotopic salivary gland of seromucose type, the histopathologic study of the surgical piece being decisive in the diagnosis. The characteristics of salivary heterotopias of the neck, and their diagnostic difficulties and histogenetic problems are reviewed.

[Cervical cystic metastasis: differential diagnosis with branchiogenic carcinoma]. / Metástasis quística cervical: diagnóstico diferencial con el carcinoma branquiógeno.

This paper try to call you attention about the cystic metastatic lesion and the differential diagnostic with the branchiogenic carcinoma. We presented a case of cystic metastases in the neck, and this case has prompted us to discuss the clinic features of these metastases.

[A case of Klippel-Feil syndrome]. / Un caso de síndrome de Klippel-Feil.

We would like to present a case of Klippel-Feil Syndrome in which it is associated with multiple cervical vertebra synostosis, short neck, cervical rib, congenital sclerosis, platybasia, spina-bifida and deafness. We are revising the case history of this syndrome.
