Rhabdomyosarcoma of the breast is a rare tumor that is characterized by its rapid growth, large size, and poor prognosis. It most often presents as a pure neoplasm and infrequently as the stromal component of a cystosarcoma phyllodes. The clinical and pathological features of a cystosarcoma with a rhabdomyosarcomatous stroma occurring in a 45-year-old woman are presented, and the results are discussed in reference to the 24 published cases of mammary rhabdomyosarcoma. The patient was treated by radical mastectomy and died 2.5 years later with pulmonary and cerebral metastases. Though two long-term survivors have been reported, cures are infrequent and no form of therapy has been uniformly successful.

With modern techniques it is usually possible to deliver a high dose of radiation to an orbital tumour without destroying vision. Local cure of lymphoma is possible with no risk of complications. Rhabdomyosarcoma now has a very good prognosis if treated energetically by radiotherapy and chemotherapy. Radiotherapy also has a part to play in the management of lacrimal gland tumours, melanoma, and metastases. A recent series of cases provides evidence that radiotherapy may be the best treatment for some cases of pseudotumour.

The paratesticular region was the primary site in 20 of 289 children (7%) entered on the Intergroup Rhabdomyosarcoma Study. The 20 patients were 1.7- to 19-years-old at diagnosis. Fifteen underwent retroperitoneal node dissection (12) or biopsy (3), and 6/15 (40%) had nodal involvement by tumor. Nineteen of the 20 patients had no gross local or metastatic disease after surgery. All 20 received chemotherapy, and 13 also received radiotherapy. Treatment was effective: 16 of 18 evaluable patients (89%) were free of disease at a median of 23 months from diagnosis (range, 8-43 months). Since the incidence of tumor-involved retroperitoneal nodes is high, a dissection should be performed. If the nodes are free of tumor, retroperitoneal radiotherapy may not be necessary. Reduction of morbidity in patients with paratesticular rhabdomyosarcoma is desirable, because the disease has a good prognosis.

Rhabdomyosarcoma represents the most common soft-tissue neoplasm of the head and neck found in children. The tumor is most commonly seen in Caucasian children under the age of 12, usually presenting as a painless mass. Distant metastases are frequently present, especially in regional lymph nodes, lung, and bone marrow. All patients suspected of having this disorder should have a thorough examination of the head and neck, as well as a complete radiographic evaluation of the primary region. Histologic disagnosis should be made as rapidly as possible. Once this has been accomplished, a thorough search for metastatic disease can be undertaken. Therapy must be individualized, and a team approach is advocated. The roles of surgery, radiation therapy, and chemotherapy are discussed. A staging system and a treatment-therapy plan are outlined.

Rhabdomyosarcoma usually presents as a soft tissue mass, which may invade adjacent bone. However, the patient presents occasionally with bony metastases. Recognition of these is important for staging and management. Fifty-eight cases have been reviewed; 14 of these had local bone invasion by the soft tissue tumour. All bones involvel were flat bones; 12 showed permeated bone destruction and two showed geographic destruction. Bone expansion was seen in half the involved bones. Twelve of the 58 cases showed secondary bone deposits, which were the presenting feature in five. Although 10 cases had permeated bone destruction, two were very well defined with a wide range of radiological appearances. The radiological differential diagnosis includes neuroblastoma, leukaemic infiltration, lymphoma, histiocytosis X, solitary and multifocal osteosarcoma and other deposits.

Rhabdomyosarcoma is a rare tumour of mesenchyme-like tissue in which differentiation of rhabdomyoblasts has occurred. It is found mainly in infants and children. The prognosis, until recent years very grave, has been improved by a combination of chemotherapy and radiotherapy occasionally with surgery. Survival depends on the extent of the disease at the time of diagnosis. Diagnostic radiology has an important role to play in the demonstration of this, illustrations of which are given from a series of seven cases. The primary tumour has no pathognomonic appearances and is demonstrated essentially as a soft tissue mass lesion which displaces adjacent soft tissue structures such as arteries, veins, bladder and colon, or erodes adjacent bones whether in the extremities or the skull. The main role of diagnostic radiology is the detection of metastases. Chest radiography and skeletal survey are mandatory. Lymphangiography may reveal filling defects in regional lymph nodes but these are indistinguishable from any other metastases. Arteriography as well as revealing displacement of larger vessels, may show typical tumour neovascularity in the lesion. Serial skeletal radiographs are of help in assessing response of metastases to therapy.

Clinico-pathologic reviews of series of children with rhabdomyosarcoma have yielded conflicting information regarding frequency of lymphatic spread of this disease. The 264 eligible entries in the Intergroup Rhabdomyosarcoma Study (from November 1972 to September 1975) have been categorized by a prospective staging system and pre-treatment characteristics and pathologic findings reviewed. Data accumulated thus far have revealed a higher than expected incidence of lymphatic metastases from extremity (17%) and genito-urinary sites (19%) with a somewhat lower incidence from the orbit (0%), the head and neck region (3%), and trunk (10%). These differences in regard to lymphatic metastases were found to have no relationship to age, sex, tumor size, or histologic type when these factors were simultaneously examined.

About 27% of malignant tumors in children is located in the head and neck. Besides primary solid tumors, lymph node metastases as well as signs of systemic diseases of the lymphatic tissue are often found in this region. The latter are the most common childhood malignancies. Among primary solid malignant tumors in this region neoplasms of the soft tissues are frequency found. Their prevalence comes next to the tumors of the central nervous system and the orbit. Rhabdomyosarcoma (RMS) represents 50% of cases in this group. Malignant neoplasms originating from epithelial and bone tissue occur rarely in children. The evolution of triple therapy, combining surgery with irradiation and chemotherapy has produced and improvement in prolonged survival rates in these children.

A retrospective analysis identified 29 children with nasopharyngeal malignancies who were evaluated at the Children's Hospital of Philadelphia from 1970 through 1989. Rhabdomyosarcoma (15) and carcinoma (9) were the most common tumor types, and there were distinct differences in the clinical presentations of these two malignancies. Patients with rhabdomyosarcoma were generally younger than those with carcinoma and enjoyed longer survival. Six (67%) of the children with carcinoma were black; all of the patients with rhabdomyosarcoma were white. Patients with carcinoma were also more likely to present with cervical metastases. The presentation, evaluation, and methods of treatment for pediatric nasopharyngeal malignancies are discussed.

Thirty-six previously untreated patients younger than 21 years of age with sarcoma arising in the perineal region were entered on the Intergroup Rhabdomyosarcoma Studies (IRS) I and II from 1972 through 1984. The tumor histologic subtype was alveolar rhabdomyosarcoma (RMS) in 20 patients (56%), embryonal RMS in 11 patients (30%), and other types of sarcoma in 5 patients (14%). Fifteen children had grossly complete surgical excision (Clinical Groups I and II), and 15 had localized gross residual tumor (Group III) after initial operative management. Six patients had distant metastases (Group IV) at diagnosis. Twelve patients without distant metastases underwent regional lymph node biopsy; tumor involvement was found in six. Subsequent treatment consisted of chemotherapy with vincristine (VCR) and dactinomycin (AMD) for all patients; patients in Groups III and IV also received cyclophosphamide (CYC) with or without Adriamycin (ADR) (doxorubicin; Adria Laboratories, Columbus, OH). Radiation therapy (RT) was administered to patients in Clinical Groups II, III, and IV. Overall, 28 (78%) patients achieved a complete clinical response. The 3-year disease-free survival rate for these patients was 42%, compared with 52% for all other patients in the combined IRS I and IRS II series (P = 0.44). The overall 3-year survival rate was 59%, compared with 64% for all other patients in IRS I and IRS II (P = 0.48). Aggressive treatment is needed in children with perineal sarcoma to improve their prognosis.
