Soft tissue giant cell tumor is a rare tumor. It occurs mainly in adults, in the lower extremities, and it has not gender predominance. Clinically it has a multinodular aspect and the best therapeutic option is a conservative surgical resection. We describe the case of a 55-year-old man with a multilobullated neoformation that affected the first toe of left foot, with a hystopathological diagnosis of giant cell tumor of soft tissues. The therapy consisted on partial amputation of the affected toe, to remove completely the tumor. [ABSTRACT FROM AUTHOR]

In recent years higher education has experienced rapid expansion due to, among other things, the imperative of preparing the tables of technical, professional and research that meet the requirements of economic development, political and social life. Based on this growth and because of the curricular issues facing higher education institutions, has created a need to rationalize and systematize the curriculum development efforts taking place in them. The concept of social need is part of the deficiencies that are identified with an ideal situation, beneficial to the individual and the community, and whose satisfaction requires the response of other members of society or its institutions. The aim of this study was to identify the demand for degree programs in humanities offered by the Faculty of Arts, in various regions of the state of Puebla, specifically in the regions of Chignahuapan-Zacatlán, Teziutlán and Tehuacan, in order that can be incorporated into the model of regionalization of the Autonomous University of Puebla. The method used for this study was descriptive and analytical to carry out a survey applied to 4075 students last semester of high school in the area of social sciences and humanities. Through this work we present the results obtained in each of the identified regions and a general comparison that shows the demand for each of the degrees offered at the Faculty of Arts.

Background: Nevus sebaceous of Jadassohn is a congenital hamartomatous lesion, which involves sebaceous gland, apocrine, and trichilemmal proliferative changes. It presents three clinical stages; the last one is characterized by epithelial tumors arising. Objective: To determine the frequency and associated tumors type, as well as the clinic and epidemiologic characteristics related with them. Material and method: A retrospective analysis at the Instituto Dermatológico de Jalisco Dr. José Barba Rubio during a five-year period was made. All histopathology reports of nevus sebaceous of Jadassohn were included and three different pathologists in a blind fashion reviewed the slides of tumors arising in nevus sebaceous. Results: We included 260 cases with diagnostic of nevus sebaceous of Jadassohn, mean age 19.7 years, female sex predominance (55%), the most frequent localization was scalp (61.5%). Eleven per cent of the 260 cases were in tumor stage, with predominance in 31 to 40 years old (27.5%). Benign tumors were the most frequent (97%), trichoblastoma predominated (50%); only one case of basal cell carcinoma was found. More than one tumor was associated to nevus sebaceous of Jadassohn in 13.7% of cases. Conclusions: Arising malignant tumors in nevus sebaceous of Jadassohn are uncommon, moreover in pediatric age. Prospective studies are necessary in order to determine the real association with nevus sebaceous of Jadassohn tumors. [ABSTRACT FROM AUTHOR]
