background: as children comprise a considerable proportion of our population, the importance of local epidemiologic research and geographic and racial differences can’t be disputed on childhood malignancies. methods: in this descriptive retrospective study, we extensively reviewed the medical records of patients younger than 15 years of age, diagnosed with solid malignant tumors, from 1996 to 2...

Nephroblastoma or Wilms tumor is a malignant that develops at the expense of embryonic kidney tissue. It most common in children (> 90%); it represents around 5% to 14% all childhood cancers. The aim our work recall contribution imaging, particular CT, management this renal tumor. This retrospective, single-center study 136 cases tumors diagnosed clinic over 2-year period. mean age patients ...

A 12-year-old girl had a 6-year history of a large soft-tissue mass in her left orbit. The tumor biopsy was previously performed elsewhere when she was 7 years old, but no treatment was offered at that time. Later, the tumor was completely excised, and histologic examination revealed a mesenchymal neoplasia with typical hemangiopericytoma features. At 9 months of follow up, no evidence of local...

One form of renal osteodystrophy secondary to chronic renal failure is the osteitis fibrosa cystica, which is the complication of secondary hyperparathyroidism. Osteitis fibrosa cystica is a histologically benign, tumor-like lesion of bones. Since early diagnosis and treatment of hyperparathyroidism is available nowadays, the development of osteitis fibrosa cystica has become rare. It can only ...

BACKGROUND Hepatoblastoma is a rare malignancy of childhood. The scarcity of adequate cell models has limited our understanding of this tumor. Here we describe and characterize a new human liver tumor cell line, Hep293TT, derived from an aggressive childhood hepatoblastoma. PROCEDURES Hep293TT cells were established using primary tumor tissues from a 5-year-old Caucasian female child. This ce...

Abstract Common pediatric malignancies often surprise clinicians with unusual presentations. In this narrative, we report two patients common childhood cancer having unique neuroophthalmic characteristics. the first case, have a child solid tumor presenting blindness without proptosis, while second case is of hematological malignancy unilateral proptosis visual impairment. The highlights that c...
