Twenty children with meningiomas (ages 18 months to 17 years) received initial therapy at the Children's Hospital of Philadelphia between January 1975 and June 1991, accounting for 2% of children with primary brain tumors seen during that time interval. All were verified histopathologically, and none had had prior irradiation. Fifteen were male and 5 female. Fifteen tumors were intracranial, all located supratentorially. Two of these also had a component within the optic canal. One tumor was entirely within the orbit. Four meningiomas arose within the spinal canal. Associated conditions were neurofibromatosis (NF) type I (1 patient), NF type II (2 patients), and a facial alveolar rhabdomyosarcoma (1 patient). A gross total resection as documented by postoperative scan and operative note was accomplished in 12 patients. Four of these relapsed, at a mean of 3.5 years from initial surgery. In 4 patients a near-total resection (> 90%) was performed. Of these, 2 progressed at 9 months and 1.5 years. One of these died of complications associated with reoperation. In 4 patients a partial resection (50-90%) was performed. Two of these progressed at 4 months and 1 year, and the other 2 have been followed for less than 2 years. Five patients received radiation therapy (RT). One patient received RT as adjunctive therapy after primary surgery because of papillary histology. The other 4 had RT following reoperation for recurrence at a mean of 1.5 years from diagnosis (range, 7 months to 2 years). These 4 patients remain alive and with stable disease at a mean of 6 years from diagnosis (range 2-8.8 years).(ABSTRACT TRUNCATED AT 250 WORDS)

The development of sarcomas in three generations of a family with neurofibromatosis (NF) is described. A 7-month-old boy developed a prostatic rhabdomyosarcoma. Family history revealed that his maternal grandmother had died of a malignant peripheral nerve sheath tumor at age 37 years and had been affected with neurofibromatosis. His mother (aged 36 years) has also developed a malignant peripheral nerve sheath tumor and NF has been confirmed in both mother and son. This family illustrates a cluster of sarcomas associated with NF and shows the importance of thorough investigation of reported family illnesses.

The most common ocular and orbital tumors presenting in infancy, childhood and adolescence are presented and discussed in this review. It has been prepared specifically for the clinical pediatrician and focuses on the clinical recognition of ophthalmic neoplasms, their diagnostic evaluation employing the use of advanced imaging techniques, biopsy when indicated and extent of disease workup. In addition, current treatment modalities are discussed. Ocular tumors addressed include: retinoblastoma, capillary hemangioma, lymphangioma, dermoid and epidermoid cysts, teratoma, glioma, astrocytic hamartoma, neurofibroma, rhabdomyosarcoma and fibrous tumors. Two aggressive and potentially fatal tumors, rhabdomyosarcoma and retinoblastoma, are presented in detail. In addition, the ocular tumors associated with the phakomatoses (von Hippel-Lindau, tuberous sclerosis and neurofibromatosis) are reviewed.

Neural crest and nonneural crest tumors occur frequently in neurofibromatosis (NF). We report one case of NF and recurrent malignant fibrous histiocytoma, a tumor that is uncommon in childhood, and another case of the concomitant occurrence of NF, hemophilia B, and a paratesticular rhabdomyosarcoma.

A paratesticular rhabdomyosarcoma occurred in a child with factor IX deficiency and neurofibromatosis, illustrating the need to consider carefully the various etiologic possibilities of a soft-tissue mass in a child with neurofibromatosis and/or a bleeding disorder.

Neural tumors, Wilms' tumor, rhabdomyosarcoma and several types of leukemia have been previously described in association with neurofibromatosis (NF). In a nation-wide collection of cases in Italy, 15 children (0-14 years of age) with NF and cancer or leukemia were identified; 13 of them had been diagnosed with cancer between 1976-83. The expected number of children with cancer and NF in 1976-83 was 4.48. The distribution of tumor types was different from that found in the general population, with a higher proportion of tumors of neural crest origin as well as soft tissue sarcomas. In 7/15 the family history was positive for NF; in 5/7 the individuals affected included the mother and/or a maternal relative.

Congenital anomalies were identified in 37 of 115 (32%) children and adolescents autopsied with rhabdomyosarcoma. An analysis of sex, age, site, and histology of cases with or without congenital anomalies showed no significant differences. Of the 45 identified anomalies, 14 were considered major and 31 minor. The distribution of the anomalies by system included central nervous (9), genitourinary (10), gastrointestinal (13), and cardiovascular systems (4). Ten patients had complex or miscellaneous anomalies. There was one child with each of the following: Rubinstein-Taybi syndrome, neurofibromatosis, single horseshoe kidney, hemihypertrophy, and Arnold-Chiari malformation. Aniridia was not noted in any case of rhabdomyosarcoma. Individuals with rhabdomyosarcoma have an increased incidence of genitourinary anomalies similar to that in Wilms' tumor. Recent molecular genetic investigations have suggested that rhabdomyosarcoma, Wilms' tumor, and hepatoblastoma share a common pathogenetic mechanism involving chromosome 11. The uniquely increased association of central nervous system anomalies with rhabdomyosarcoma and absence of aniridia would support a different gene locus operative on chromosome 11 for individuals with rhabdomyosarcoma compared to Wilms' tumor. Extensive epidemiologic studies now in progress in patients with rhabdomyosarcoma should provide the incidence of congenital anomalies and potential linkage with prenatal events.

We have described a case of rhabdomyosarcoma arising in a patient with neurofibromatosis. Local surgery, chemotherapy, and radiation therapy all seemed to play an essential role in treating this highly malignant tumor.

Marked dissimilarities in the epidemiology of osteosarcoma, Ewing's tumor, and rhabdomyosarcoma indicate differences in their origins. A major clue to the genesis of Ewing's tumor comes not from defining persons at high risk but from the observation that blacks are at unusually low risk. The neoplasm does not aggregate in families and is not part of any known syndrome. No environmental causes have been identified. By contrast, osteosarcoma may be caused by external or internal ionizing radiation, and it aggregated in families with the same tumor or with dissimilar tumors and in certain genetic disorders of bone. In man and in dogs, the frequency of the neoplasm is related to bone mass and growth. Rhabdomyosarcoma of the upper versus the lower limbs seems related to muscle mass. Age peaks in the occurrence of the tumor elsewhere vary with the anatomic site; head and neck tumors develop in early childhood and urogenital tumors both in early years and in adolescence. The sex ratio (male to female) also varies with the site affected. Rhabdomyosarcoma aggregates with certain other tumors in families and overlaps with osteosarcoma in some of these relationships but is distinguished from that tumor by its excessive occurrence in neurofibromatosis.
