ABSTRACT
Los carcinosarcomas son tumores bifásicos constituidos por elementos epiteliales y mesenquimales malignos. SOn neoplasias muy raras en la piel, recogiéndose en la literatura únicamente 11 casos. Presentamos un nuevo caso con metástasis ganglionares. La histogénesis de los carcinosarcomas es muy controvertida; discutimos las distintas teorías y nombres utilizados para designar esta neoplasias (AU)

Presentamos un caso poco frecuente de carcinoma lobulilIar invadiendo un hamartoma mamario.El hamartoma es una lesión benigna de la mama que tiene unas determinadas características clínicas y mamográficas, siendo fácil que la irrupción de un carcinoma pase desapercibida.Analizamos las características de uno y otro tipo de tumor, teniendo en cuenta la rareza de su aparición conjunta y la importancia de su rápido diagnóstico y tratamiento (AU)

A case is reported of a patient with a lentiginous acral melanoma of the heel that was excised and recurred 3 years later at the margin of the previous scar. After another 3 years, a group of five small lesions appeared in the thigh that were considered to be junctional and epidermotropic metastases. The authors question the current histologic criteria for differentiating junctional and epidermotropic metastases of previous melanomas from multiple primary melanomas. It is concluded that the clinical history is of primary importance in reaching a correct diagnosis; histologic studies are not sufficient.
