Multiple fractures due to osteogenesis imperfecta mistaken as child abuse
A 15-month-old African–American boy receiving chemotherapy for Wilms tumour was diagnosed to have a fracture of left femur at the emergency department (ED) of our hospital. A month earlier, the patient had been seen at the same ED for a fracture of right femur. The skeletal survey this time also showed an old posterior rib fracture. Child abuse was suspected. The child’s custody was transferred to the maternal grandparents. However, 2 months later while with the grandparents, he sustained a fracture of the left distal tibia. This led to an investigation for osteogenesis imperfecta (OI). The child was found to have a collagen mutation, COL1A1, strongly suggesting that the child’s multiple fractures were most likely due to OI
Sudden progressive abdominal pain due to large peritoneal desmoid tumor: A case report with review of literature
AbstractDesmoid tumor (musculoaponeurotic fibromatosis) is a rare locally aggressive soft tissue tumor. A subset of cases is associated with familial adenomatous polyposis (FAP), governed by the APC (adenomatous polyposis coli) gene. Typically, an intra-abdominal desmoid is a painless lump or mass with a slow progression. We report a case of 14 year old male with Asperger syndrome who presented to our hospital with acute onset of progressively worsening abdominal pain. On the physical examination a large abdominal mass was palpated in the left upper quadrant. An abdominal CT (computerized tomography) scan confirmed the mass. The tumor was resected with free tumor cell margin. The histological diagnosis was desmoid fibromatosis. The nuclear β-catenin immunohistochemistry was positive. The tumor had encroached the splenic vessels and infarcted spleen. This splenic infarction was most likely the cause of the sudden abdominal pain. The patient is alive with no postoperative symptoms or evidence of the disease 6 months after the surgery. Family history and genetic analysis of the APC gene were negative for FAP
