RESUMEN
PURPOSE: Solid ovarian tumours are uncommon in childhood. Our aim is to evaluate the outcomes in a single institution over 35 years. METHODS: We reviewed their clinical presentation, management, pathology and outcomes from 1972 to 2007. RESULTS: Fifty-three patients, with a median age of 9.2 years (range 0.9-14.2), were registered. Common symptoms at presentation were abdominal pain (75.8%) and abdominal mass (57.4%). Histopathological diagnoses were: 26 mature teratoma, 10 immature teratoma, 8 dysgerminoma, 5 granulosa cell tumours, 2 yolk sac tumours, 1 gonadoblastoma and 1 embryonal carcinoma. Staging (FIGO) for malignant/borderline tumours was: 17 stage I, 1 stage II, 8 stage III and 1 stage IV. Unilateral salpingo-oophorectomy was performed in 47 cases. Sixteen patients underwent chemotherapy after surgery (15 with platinum-based regimen) and postoperative radiotherapy was given in 5 cases. Recurrence was observed in 2 patients and one died (stage III immature teratoma) after a second relapse despite multiple chemotherapy, surgery and radiotherapy. Five-year OS and 5-year EFS were 97% and 94% respectively. CONCLUSIONS: Although rare, ovarian tumours must be included in the differential diagnosis of abdominal pain in childhood. Our results confirm their excellent prognosis using conservative surgery and platinum-based chemotherapy. The key point is to maintain excellent outcome while reducing associated morbidity and preserving fertility.

INTRODUCTION: Posttransplant lymphoproliferative disorder (PTLD) constitutes a heterogeneous group of diseases. We summarize the experience of our hospital, one of Spain's largest series of renal (294), liver (47) and allogeneic stem cell transplants (67), where four cases of PTLD have developed related to complex viral infections. METHODS: Case 1 was a 24-month-old boy diagnosed with acute lymphoblastic leukemia who underwent allogeneic stem-cell transplantation (SCT). He was seropositive for Epstein-Barr virus (EBV) and developed an aggressive Bcell non-Hodgkin's lymphoma (B-NHL) related to EBV reactivation and human herpesvirus 6 (HHV-6) infection. Cases 2, 3, and 4 developed after kidney transplantation and were all EBV seronegative. Case 2 had associated cytomegalovirus (CMV) and EBV infection. Cases 3 and 4 only revealed EBV viral load. Cases 1, 3, and 4 progressed rapidly, with fatal outcome. Global incidence of PTLD in our series is 1.1%. CONCLUSION: PTLD is a rare but life-threatening condition. Although EBV plays a clear role in its pathogenesis, other associated viral infections could trigger this situation. Current therapies include rituximab, decreasing immunosuppressive drugs. and conventional chemotherapy.
