Perfil epidemiológico de neoplasias epiteliales de glándulas salivales / Epithelial tumors of salivary glands: review of 286 pathology reports

Background:: Epithelial tumors of the salivary glands, including benign tumors and aggressive malignancies with different prognoses, are uncommon. Aim: To describe the frequency and distribution of salivary gland tumors according to age, gender and anatomical location. Material and Methods: Review of pathological reports of salivary gland tumors of a Pathology laboratory at a clinical hospital from 2006 to 2016. Results: Five hundred ninety salivary gland biopsies were reviewed. Of these, 286 (49%) were primary epithelial tumors of the salivary glands. Two hundred thirty (80%) were benign and 56 (20%) were malignant tumors. Regarding location, 274 (96%) were in the major salivary glands, and 12 (4%) in the minor salivary glands. The most common histological types were pleomorphic adenoma for benign tumors in 172 cases, followed by papillary cystadenoma lymphomatosum in 33 cases. Mucoepidermoid carcinoma was the most common malignant tumor in 14 cases. Conclusions: These results are similar to reports from abroad, however more studies are necessary to be able to establish a more representative and updated analysis.

Squamous cell carcinoma of the conjunctiva with extraocular involvement: case report and literature review. / Carcinoma escamoso de la conjuntiva con compromiso extraocular: reporte de caso y revisión de la literatura.

Squamous cell carcinoma of the conjunctiva is the most frequent malignant tumor of the ocular surface. It is a rare disease with an incidence of 0.13 to 1.9 per 100,000 inhabitants, mainly affecting individuals between 50 and 75 years of age. It tends to have a slow, non-aggressive course. Treatment depends on the extent of the tumor. If there is intraocular involvement, enucleation is indicated, and in the presence of extraocular involvement the orbital exenteration is the standard treatment. We report and discuss the case of an 82 year old male patient having a conjunctival squamous cell carcinoma with intra and extraocular involvement, together with a review of the literature.

El carcinoma escamoso de la conjuntiva es el tumor maligno más frecuente de la superficie ocular. Constituye una enfermedad rara con una incidencia de 0,13 a 1,9 por 100 000 habitantes que afecta principalmente a individuos entre los 50 y los 75 años. Suele tener un curso lento y poco agresivo. El tratamiento depende de la extensión tumoral. En presencia de compromiso intraocular la enucleación está indicada y en presencia de compromiso extraocular la exanteración orbitaria es el tratamiento estándar. Reportamos el caso de un paciente de 82 años con carcinoma escamoso conjuntival con compromiso intra y extraocular, se discute el caso y se revisa la literatura.
