Late recurrence of ovarian granulosa cell tumor at the retroperitoneal and renal hilum level in a single-kidney patient--case report.

BACKGROUND: Ovarian granulosa cell tumors are rare tumors characterized by a long natural history and a tendency to late recurrence. Surgical resection, radiotherapy, chemotherapy and hormone therapy are possible options to treat recurrent disease. The choice will depend on the patient's condition and the site of recurrence. CASE: We describe the case of a 72-year-old patient with a single left kidney who presented retroperitoneal recurrence of ovarian granulosa cell tumor at the left renal hilum ten years after primary treatment. CONCLUSION: This case illustrates an example of very late recurrence and emphasizes the importance of extended follow-up for these patients.

Ongoing changes in the social, economic, technological and scientific realms have generated new needs and led various organizations to suggest that educational institutions should reorient their educational strategies toward developing effective professionals with the skills to meet these needs. These "modern" strategies include problem-based learning, in which the student seeks and selects information, analyzes the data obtained, integrates both prior and newly acquired knowledge, and, finally, offers diagnostic and therapeutic options to resolve the problem posed, as would occur in professional practice. With this approach, prior skills and practical experience form the foundation of learning. Problem-based learning incorporates some aspects of cognitive psychology, a model that mainly centers on the nature of the knowledge structures found in active memory, the processes involved in information storage and retrieval and the various factors that activate these processes. At the Faculty of Medicine of the Universidad de Castilla-La Mancha, urology is part of a core subject (Medical and Surgical Pathology II) taught in the fifth year of coursework together with nephrology. Each course includes approximately 75 students, divided into five groups. The rotation lasts six weeks, with students spending a mean of two hours a day on theory (nephrology and/or urology) and the remaining time on rotations in the various activities: three weeks in nephrology and three weeks in urology. Upon completion of the rotation, the students write a combined theoretical examination with 100 multiple-choice questions (50 on urology) and take a practical skills examination. At the end of the course, another practical test consisting of an objective, structured clinical examination is taken, in which standard patients are used and the professor directly assesses the level of skills acquired with a "real" case.

[Eosinophilic cystitis and glandular-cystic cystitis as pseudotumor lesions]. / Cistitis eosinofílica y cistitis glánduloquística como lesiones seudotumorales.

OBJECTIVES: To report on two different types of cystitis presenting as pseudotumor. The differential diagnosis between the foregoing lesions and true tumors can only be established by biopsy. METHODS: We report two cases of cystitis (eosinophilic cystitis and glandular-cystic cystitis) with clinical, radiological and endoscopic features of a bladder tumor. The diagnosis, etiopathological aspects, clinical course and treatment of both types of cystitis are reviewed. RESULTS/CONCLUSIONS: Hematuria is the most frequent and most important symptom of these uncommon lesions. They present as space occupying lesions in more than 50% of the cases and have no specific diagnostic features. The diagnosis can only be made by pathological examination following TUR-biopsy.
