[Schwannomas of the lingual nerve]. / Schwanoma del nervio lingual.

Schwanomas in extracranial head and neck region are an uncommon tumour, but when refered to its origin in the parasympathetic nerve fibers are extremely rare. We describe a case of schwanoma of the right submandibular gland originating from the parasympathetic branch of the lingual nerve, and we discuss about the clinical, diagnostic and therapeutic aspects of this rare tumour and a literature review of the recent cases.

Schwannoma del nervio lingual / Schwannomas of the lingual nerve

Los schwannomas de cabeza y cuello extracraneales constituyen una variedad tumoral relativamente infrecuente, pero cuando hablamos de su origen en las fibras parasimpáticas del nervio lingual se convierten en algo excepcional. Presentamos un caso de schwanoma de la región submandibular derecha originado en las ramas parasimpáticas que el nervio lingual proporciona a la glándula submaxilar, realizando una discusión acerca de los aspectos clínicos, diagnósticos y terapéuticos de esta variedad tumoral y una revisión de los casos descritos en la literatura médica reciente

[Nasoalveolar cyst. Five new cases]. / Quistes nasoalveolares. Presentación de 5 nuevos casos.

Nasoalverolar cyst are nonodontogenic maxillary cysts, rare and benign, which are more common in females and blacks. Their diagnosis can be established mainly on the clinical presentation, being usually asymptomatic during several years until they are large enough to cause cosmetic deformities and/or nasal obstruction, with asymmetrical alar flare. The treatment of choice is the complete surgical excision via a sublabial approach. Five cases diagnosed and treated at the Santa Maria del Rosell Hospital are reported, describing the most relevant clinican and pathological findings, so the diagnostic ant therapeutic methods.

Quistes nasoalveolares. Presentación de 5 nuevos casos / Nasoalveolar cyst. Five new cases

Inverted papilloma is a benign sinonasal tumour with a high recurrence rate and its treatment must be surgery, using endonasal surgery or external aproach. We present a retrospective study of 23 cases treated in our center from 1988 to 2003. There 15 males and 8 females with a mean follow-up of 6 years. The recurrence rate was 40,9%. Patients who underwent endonasal surgery had a recurrence rate of 36,6% and those who underwent external approach surgery had a recurrence rate of 45,5%. There was a 4,5% of association with carcinoma. Endonasal surgery might be a valid surgery approach for the treatement of inverted papilloma in select cases

Nasoalveolar cyst are nonodontogenic maxillary cysts, rare and benign, which are more common in females and blacks. Their diagnosis can be established mainly on the clinical presentation, being usually asymptomatic during several years until they are large enough to cause cosmetic deformities and/or nasal obstruction, with asummetrical alarflare. The treatment of choice is the complete surgical excision via a sublabial approach. Five cases diagnosed an treated at the Santa María del Rosell Hospital are reported, describing the most relevant clinican and pathological findings, so the diagnostic and therapeutic methods

[Tuberculosis of the parotid gland]. / Tuberculosis parotídea.

We present a case of parotid tuberculosis diagnosed through F.N.A.C. (fine needle aspiration cytology). Due to this rare extrapulmonary location of the tuberculosis, the AA. make a review of the last 12 years concerning literature together with a monographic study of the process.

[Malignant tumor upon pleomorphic adenoma of long development, a case report]. / Tumor maligno sobre adenoma pleomorfo de larga evolución a propósito de un caso.

We have studied a 67 years old woman suffering from a 40 years evolution Pleomorphic adenoma. The specimen weighed 250 g, and showed several areas displaying carcinoma. This report confirms the relationship between long-term evolution and malignant transformation.
