Thirty-eight girls with malignant ovarian tumors were reviewed and studied during a 43-year period, 1945 to 1988 inclusive. The age range was 3 to 16 years. Eighteen girls were prepubertal and 16 were pubertal at diagnosis. Precocious puberty was noted in 4 children. The most common presenting symptoms and signs were pain, abdominal swelling, and pelvic mass. Emergency surgery for acute pain (? appendicitis) was needed in only 7 patients. Tumor size and cysts did not relate to histology or outcome. Tumors were classified histologically (germ cell, sex cord/stromal, epithelial tumors). Twenty-one (54%) of the patients survived 1 to 27 years (median, 8 years). Sixteen were left with ovarian tissue, 11 functioning. Diagnosis and treatment have been aided by better noninvasive radiological methods, tumor markers, newer and better chemotherapy, and pathological review and reclassification of these tumors as pediatric experience slowly increases. We can make at least four statements that differ from our past experience: (1) pure endodermal sinus tumor was previously confused histologically with embryonal carcinoma; (2) gonadoblastoma is associated with 45,X/46,Y, 45,X, or 46,Y karyotype and is known to be premalignant; (3) sex cord/stromal tumors are not necessarily malignant and metastatic behavior cannot be predicted from the histology; and (4) currently, epithelial tumors are classified as cystadenomas and are considered to be borderline malignancy. Current management should aim at both cure and preservation of fertility with conservative surgery whenever possible. The future must lie in chemotherapy.

Gastrointestinal stromal tumors are the most common mesenchymal tumors of the gastrointestinal tract. These tumors are present in almost all case mutations of KIT-CD117. When located in different places other than the gastrointestinal tract they are called extragastrointestinal stromal tumors (EGISTs). We present the case of a 70-year old patient with abdominal pain. Computed tomography (C/T) and ultrasound (U/S) indicated the existence of a hypoechoic enlarged 9.6 x 10 cm uterus due to leiomyoma. The clinical condition of the patient deteriorated and obtained the characteristics of an acute abdomen. The patient underwent urgent exploratory laparotomy, which revealed the incidental existence of a large tumorous formation in the pouch of Douglas. A total abdominal hysterectomy, bilateral ovarectomy, omentectomy, and tumor resection from the rectouterine pouch were performed. Histology analysis confirmed the diagnosis of a malignant EGIST. EGISTs are infrequent in pelvis. In our case, pelvic EGIST led to an acute pain symptomatology obtaining characteristics of invasive uterine leiomyosarcoma. Pelvic imaging with classical methods of U/S and C/T may lead to confusion and false diagnosis. To the best of our knowledge, this is the first case report about an EGIST located in the rectouterine pouch of Douglas leading to acute abdomen symptomatology.
