ABSTRACT This 16-year-old boy with Proteus syndrome suffered acute spinal cord compression secondary to hemorrhage into an extradural paraspinal angiolipomatous hamartoma. A magnetic resonance (MR) imaging study performed 12 years earlier had revealed the presence of this tumor at the apex of a mild thoracic scoliosis, which had been stable during the intervening decade. Spinal cord neurological deficit in Proteus syndrome is rare. It can arise either from vertebral abnormalities and kyphoscoliotic deformities or from tumor encroachment. The authors describe the temporal evolution of scoliosis and acute spinal cord compression caused by a paraspinal angiolipomatous hamartoma over a period of 12 years. A review of the literature suggests that regular follow up, including serial MR imaging, is indicated in children with Proteus syndrome and scoliosis. Earlier resection of extradural tumor mass encroaching on the cord is warranted in the treatment of these children.

    ABSTRACT: Background-AimGastrointestinal angiolipomas are rare benign lipomatous lesions first described by Bowen in 1912 and differentiated histologically by Howard in 1960. Duodenal angiolipomas represent a rare pathological condition that can lead to severe gastrointestinal bleeding; they may be treated successfully surgically and occasionally endoscopically. We report the 3rd case of duodenal angiolipoma to be reported in the literature between 1964 and 2010. MethodDatabases from Pubmed and Medline were searched using a list of keywords such as angiolipomas, gastrointestinal bleeding, duodenal angiolipomas and references from review articles. Results: 21 reported cases of gastrointestinal angiolipomas have been reported, including 1 case of the oesophagus, 3 of the stomach, 2 of the duodenum, 7 of the small intestine, 2 of the caecum, 4 of the large intestine and 2 cases of the rectum. ConclusionIt is important to include the presence of angiolipomas in the differential diagnosis of gastrointestinal bleeding. These benign lesions may lead to severe bleeding. Careful evaluation and preoperative work up of the patient will determine the treatment of choice and reduce postoperative complications.

    ABSTRACT: Angiolipoma is a rare vascular variant of the benign lipomatous tumors and is generally seen in subcutaneous tissues. We report a 70-year-old female with abdominal distension not related to rectal small polypoid mass with peduncule described as angiolipoma by histologically, and review the literature.

    ABSTRACT: Proteus syndrome is a rare, sporadic, hamartomatous disorder manifesting with multifocal overgrowth of tissue. The features seem to develop most often during childhood. Vertebral overgrowth with severe spinal canal stenosis is unusual, although scoliosis with abnormal vertebral bodies is one of the typical features of Proteus syndrome. We report a case of Proteus syndrome with severe spinal canal stenosis, scoliosis, cervical kyphosis, and thoracic deformity with airway obstruction because of asymmetrical overgrowth of vertebrae and ribs associated with a tethered cord, lipomas, strawberry hemangioma, flat nasal bridge, and bilateral hypoplasty of the first metatarsal bones with hyperplasty of soft tissue.
