RESUMEN
The authors presents a clinical case treated with brachytherapy performed with special mold of gold-198 disc, with the purpose of evaluating the distribution of radiation dose, the viability of manufacturing the radioactivity prosthesis and its operational cost. In despite of being only one case, we can conclude that the prosthesis with gold-198 foils can be manufactured in acrylic with thickness thinner than those ones with cylinder of cesium-137, resulting lower operational costs, besides permitting better distribution of radiation dose on the lesion.

A case of basaloid squamous carcinoma that involves the posterior buccal mucosa is described. The major histopathologic feature is a carcinoma with a basaloid pattern in association with squamous differentiation. The basaloid cells exhibit large and vesicular nuclei and eosinophilic clear or vacuolated cytoplasm. Cells are distributed in cords, trabeculae, or lobules that occasionally show glandular arrangement. The majority of the tumor cells are positive for keratin and a large group of cells distributed in glandular arrangement are positive also for vimentin.
