Juvenile Fibrosarcoma of the Orbit and Eyelid

Pediatric Orbit Tumors and Tumorlike Lesions: Nonosseous Lesions of the Extraocular Orbit

“…Although fibrosarcomas are more likely to be hypercellular with a characteristic herringbone pattern (Fig 16d), to have infiltrating margins, and to have higher mitotic activity, their histologic appearance overlaps too much with that of infantile fibromatosis to allow prediction of the behavior of an individual tumor based on histologic characteristics alone. In fact, some authors believe that in infants the only reliable diagnostic criterion for malignancy is the presence of metastases (43)(44)(45)47,48). …”

Letter to the editor regarding single-site laparoscopic gastrostomy in children

“…The tumor principally involves the extremities, trunk, head, and neck regions and has also been documented at unusual locations, including the retroperitoneum, mesentery, orbit, and ovary [9,10]. More recent articles document the occurrence of congenital gastrointestinal fibrosarcomas involving the duodenum, jejunum, and colon, most often presenting with bowel perforation [2,4,5].…”
