Pancreatoblastoma in an Older Adult

Introduction Pancreatoblastoma is a malignant embryonal tumor originating from epithelial cells of the exocrine pancreas with frequent local invasion, recurrence, and metastasis. It usually occurs in the first decade of life. Clinical Case: A 76-year-old female patient, with a 3-month history of a palpable abdominal mass in the left abdomen and weight loss (7 kg in the last month). A CT scan of the abdomen and pelvis reported a tumor in the left kidney measuring 23x11x15cm and a tumor measuring 6x5.6cm in the uterus, which showed a mixed component of probable right ovary origin. Exploratory laparotomy was performed revealing a tumor of approximately 30 cm in diameter with infiltration of the greater omentum, left kidney, left ureter, pancreas tail, and descending colon. Histopathological findings were compatible with pancreatoblastoma. Conclusion: The relevance of considering pancreatoblastomas as a differencial diagnosis in adult patients with retroperitoneal masses needs to be highlighted.
