Morphol., 35(3):1129-1132, 2017. SUMMARY: Most anatomical and biomechanical studies on the craniovertebral junction have involved morphological or morphometric analysis on the occipital condyles. Some of these studies have provided important findings based on different surgical procedures. The shape, size and angle of the occipital condyles and the locations of the intracranial and extracranial orifices of the hypoglossal canal are highly important because they may affect the lateral approaches to the craniovertebral junction. To determine the frequency of occurrence of different morphological types of occipital condyle. 214 occipital condyles in 107 dry human skulls were analyzed and the classification of their morphological types was determined through assessing digitized photographic images. Among the 107 skulls analyzed, 59.8 % were male and 40.2 % were female. Their ages ranged from 11 to 91 years, with a mean of 57.56 years. Of the total of 10 morphological types of occipital condyle that were found, more than 50 % were of the "8", "S" and ring types. Condyles of "8" and "S" shape were the main types found in male skulls: the "8" shape prevailed on the left side and the "S" shape on the right side. However, in female skulls, these two types had equal bilateral distribution.

RESUMEN METÁSTASIS SUPRARRENAL DE SARCOMA DE EWING. A PROPÓSITO DE UN CASOLos tumores metastásicos suprarrenales son más frecuentes que el carcinoma suprarrenal primario. Por orden de frecuencia se detectan metástasis de carcinomas de mama y pulmón, adenocarcinomas renal y gástrico, carcinoma de glándula suprarrenal contralateral y melanoma. Menos frecuentes son las de carcinomas de vejiga, colon, esófago, vesícula biliar, hígado, pán-creas, próstata, estómago y útero. El resto de los tumores raramente se diseminan hacia las glán-dulas suprarrenales.La afectación metastásica de la glándula suprarrenal por tumores de estirpe sarcomatosa es excepcional y suele darse en el contexto de una enfermedad diseminada con metástasis multiorgánicas.Presentamos el caso de un paciente con metástasis suprarrenal de sarcoma de Ewing que nos es remitido para tratamiento quirúrgico con intención curativa, al tratarse de una metástasis única, ya que no se objetivan signos de enfermedad en otros órganos en el momento de hallarse la citada lesión.PALABRAS CLAVE: Sarcoma de Ewing. Metástasis. Glándula suprarrenal. ABSTRACT ADRENAL METASTASES OF EWING'S SARCOMA. A PROPOS OF ONE CASEAdrenal metastases are more frecuent than primary adrenal carcinoma. The most frequent are, in this order: breast and lung cancer, stomach and kidney carcinomas, adrenal gland contralateral tumors and melanoma. Less frequent are tumours of the bladder, colon, esophagus, gall bladder, liver, pancreas, prostate, stomach and uterus. The rest of the tumours rarely spread toward adrenal glands.The metastases to the adrenal glands caused by sarcomas are rare and normaly they happen in the constest of a masive metastases afecting several organs at the same time.We present a case of a patient affected by adrenal metastases of Ewing´s sarcoma who has been referred to us for surgical treatment because it is a unique metastases (there is no sing of more illnesses in other organs at the time of the exploration).
