RESUMO
Los berries son frutos ampliamente estudiados y por décadas se han usados en distintas especialidades como herramienta terapéutica. Se han realizado múltiples estudios que demuestran los efectos beneficiosos de su consumo y el uso de sus componentes en diferentes presentaciones. En la literatura mundial no existen publicaciones de casos clínicos del área dermatológica tratados con formulaciones en base a berries. La siguiente revisión presenta evidencias que apoyan los potenciales efectos beneficiosos de los componentes de los berries y sus acciones terapéuticas en el área de la salud.
Berry fruits have been widely studied. They have been used as a ther-apeutic tool in a lot of areas in medicine. There have been many stud-ies that show the benefi cial eff ects of its consumption and the use ofits components in different presentations. In the international literature there are no reports of clinical cases of the dermatologic area treated with formulations on the basis of berries. The following review will present evidences supporting that berries components and its actions can exert potencially healthy effects.

El carcinoma de células de Merkel es un raro carcinoma neuroendocrino primario de la piel que generalmente se presenta como un nódulo redondeado, violáceo, solitario o como una placa indurada en áreas fotoexpuestas de pacientes añosos. El diagnóstico histopatológico puede ser difícil debido a su semejanza con el carcinoma metastásico de células pequeñas de pulmón, linfomas y otros tumores cutáneos. Para la distinción de tumores primarios pobremente diferenciados o metástasis se requiere de análisis inmunohistoquímico. La citoqueratina 20 constituye un marcador sensible y específico para este tumor y es útil para distinguirlo de otras neoplasias, malignas o benignas. Presentamos dos casos vistos en nuestro Servicio con este diagnóstico y una breve revisión de la literatura.
Merkel cell carcinoma is a rare primary neuroendocrine carcinoma of the skin that usually appears as a solitary, violaceous, dome-shaped nodule or indurated plaque in a sun exposed area of elderly patients. Histopathologic diagnosis may be difficult because of histologic and immunohistochemical similarities with metastatic small cell lung carcinomas, lymphomas, and other cutaneous neoplasms. Distinction from poorly differentiated oat cell primary tumors or metastasis requires immunohistochemical analysis. Cytokeratin 20 is a sensitive and specific marker for Merkel cell carcinoma and is helpful in distinguishing this tumor among other malignant and benign neoplasms. We report two cases with this diagnosis seen at our department and a brief report of the literature.

Mites that affect animals (acariasis) can occasionally be transmitted to humans by incidental contact producing pruritus and dermatitis. Animals such as dogs, cats, mice, birds and reptiles, harbour several mite species. Hemophage mites and those that feed on lymph have the potential of transmitting important zoonotic agents (cuales??). The presence of lesions of unclear origin and a history of contact with pets or wild animals should alert towards the possibility of acariasis. Diagnosis is based on direct visualization of the mite,analysis of its morphology and obtaining information on the animal host. Awareness of these acarosis and the responsible care of pets and animals are the most relevant preventive measures.
