Two cases of
rhabdomyosarcoma
in the head and neck with neurological manifestations are presented. Brain scan demonstrated an apparent area of increased uptake of 99mTc in the tumor. Cerebral angiography revealed a sharply demarcated but rather faint tumor stain. The contributing vessels were hypertrophied branches of the external carotid artery, a dural branch of the internal carotid artery, and branches of the vetebrobasilar systes emphasized because the recent combination of chemotherapy in conjuction with surgery and irradiation seems to be encouraging.

Fiberoptic instruments have improved the accuracy of diagnosis of lesions of the upper digestive tract, particularly since the capability to perform biopsy under direct vision has been developed. Primary
rhabdomyosarcoma
of the upper gastrointestinal tract is an extremely rare entity. A literature search has revealed only 10 instances of
rhabdomyosarcoma
involving the esophagus, stomach, or duodenum (1-5). In this report, we describe the use of fiberoptic diagnosis and gastroduodenoscopic biopsy in a patient with
rhabdomyosarcoma
of the stomach and duodenum.

12 mouse rhabdomyosarcomas from V--XI transplant generations were investigated at their growing in the anterior chamber of the eye, in the testis, lungs and subcutaneous fibrous tissue. With these modes of transplantation rhabdomyosarcomas were seen differentiating to different levels and differed in their cell populations. The most differentiated rhabdomyosarcomas were in the anterior chamber of the eye: they formed myotubes with cross-striated myofibrilles; the least differentiated ones occurring in lungs.

, inoculated in testes, intensively dessiminated in the lymph-nodes and in the organs of abdomen. It is concluded that the degree of tumor autonomy depends on the tumor--organism interactions.

The RD cell line, derived from a human
rhabdomyosarcoma
, supported replication of a number of group A coxsackieviruses, including types A5 and A6 which heretofore have been propagable only in suckling mice. A number of the group A coxsackievirus types which replicated in RD cells had higher titers in this cell line than in other cell culture systems. In tests on a limited number of clinical specimens, RD cells were slightly less sensitive than suckling mice for isolation of group A coxsackieviruses, but they did permit the recovery of certain virus types which previously could be isolated only in suckling mice. Group B coxsackieviruses replicated poorly or not at all in RD cells.

A case of
rhabdomyosarcoma
of the larynx in a 54-year-old man is reported. Patient presented dramatically with a large tumour mass obstructing his laryngeal inlet. The patient remains alive and well sixteen months after a total laryngectomy. Only seven previous reports of a
rhabdomyosarcoma
of the larynx could be found in the literature and these are compared with the case reported. It would seem that a
rhabdomyosarcoma
of the larynx has a better prognosis than elsewhere in the body, probably because of its earlier recognition and accessibility to radical surgery.

A case of ganglioneuroblastoma associated with malignant mesenchymoma is reported. The tumor originated from the retroperitoneum and was comprised not only of neuroblastoma and ganglioneuroma, but also of typical
rhabdomyosarcoma
, liposarcoma, undifferentiated mesenchymoma, as well as cartilaginous tissue. No distinct border existed between thses different components. The histogenesis of the tumor is discussed. We suggest that the tumor derived from a remnant of neural crest (ectomesenchyme).

Paranuclear blue inclusions (PBIs) are frequently identified within metastatic undifferentiated small cell carcinoma (SCC) cells on air-dried bone marrow aspirates stained with Wright's stain. To determine the sensitivity and specificity of this finding, 116 bone marrow aspirates containing metastatic neoplasms were evaluated for the presence and frequency of PBIs. Bone marrow specimens included 47 cases of metastatic SCC of the lung, 13 cases of large cell lymphoma, 19 cases of neuroblastoma, five cases of small, noncleaved cell lymphoma, seven cases of
rhabdomyosarcoma
, three cases of Ewing's sarcoma, three cases of other sarcomas, and 19 cases of non-small cell carcinoma (adenocarcinoma). PBIs were identified in 40 of 47 (85%) cases of SCC and their frequency varied from 0 to 24% of tumor cells among different cases. In approximately half the cases of SCC, PBIs were identified in 1 to 4% tumor cells; and in eight cases, PBIs were present in 5% or more of tumor cells. PBIs were also identified in two of seven (29%) cases of
rhabdomyosarcoma
and one case of malignant peripheral nerve sheath tumor, but they were not seen in Ewing's sarcoma, small non-cleaved cell lymphoma, large cell lymphoma, neuroblastoma, or non-small cell carcinoma. In addition, PBIs were not seen in alcohol-fixed, Papanicolaou-stained cytology specimens containing SCC. Ultrastructurally, PBIs may represent phagocytized nuclear/cellular material. PBIs are a feature of small cell carcinoma on air-dried, cytologic material stained with Romanowsky type stains. Their presence may provide diagnostic information with regard to the differential diagnosis of metastatic SCC in the bone marrow. Future studies evaluating non-bone marrow Wright's stained fine-needle aspiration specimens are needed to determine if PBIs are useful in distinguishing SCC from other poorly differentiated tumors in the cytology laboratory.

Primary cardiac
rhabdomyosarcoma
is rare and its extension to the mitral valve even rarer. We report a case of left atrial
rhabdomyosarcoma
involving the mitral valve. The patient was a 62-year-old man who complained of recurrent pre-syncopal episodes, dyspnoea often sudden in onset, asthenia and major weight loss (10 kg in one month). 2-D echocardiography revealed a 4.9 cm2 wide mass attached to the atrial side of the anterior mitral leaflet and to the adjacent inferior interatrial septum, where it seemed to have origin. CT scan and scintigraphy revealed bone, kidney and spleen metastases. The patient underwent emergency cardiac surgery because of increasing pre-syncopal and dyspnoeic episodes due to obstruction by the intracardiac mass. At surgery a tumor was found infiltrating the left atrial wall, the interatrial septum, the mitral anulus and the anterior mitral leaflet up to its tip. Invasion of mitral anulus did not allow mitral valve replacement, so that an excision of the intracardiac mass was performed as extensively as possible. Histology revealed a
rhabdomyosarcoma
. A post-operative chemotherapy cycle had to be stopped due to onset of atrial fibrillation and dyspnoea. 2-D echo monitoring revealed rapid new growth of the tumor across the basal portion of mitral valve leaflet to the atrioventricular orifice. After several episodes of increasing dyspnoea, the patient had a pulmonary oedema and died.

Primary
rhabdomyosarcoma
can arise in the skin, but there are few reports on this common childhood malignancy in the dermatological literature. We report on a male infant with a cutaneous tumour growing on the right nasal bridge since his 10th week of life. Clinically the tumour mimicked pilomatrixoma. Histological and immunohistological examination of the skin tumour and of subsequent lymph node metastases revealed
rhabdomyosarcoma
of the alveolar growth pattern. Our patient died at the age of 4 years of disseminated organ metastases.

A case of a mammary leiomyosarcoma in a 23-year-old woman is presented. The tumor appeared 16 years after successful treatment of an embryonal rhabdomyosarcoma of the orbit.
Rhabdomyosarcomas
are the most frequent soft tissue tumors of childhood, the orbit and the paratesticular region being the most common primary site for this tumor. In contrast, leiomyosarcomas other than those evolving from the viscera or the urogenital organs are rare neoplasms at any age. With the improvement of cancer treatment and survival rates, the risk of late effects after successful treatment for malignant tumors during childhood is increasing. Growth, development and fertility may be impaired and cosmetically disturbing facial and dental complications are common. Development of novel primary tumors is a known further consequence of successful treatment of brain tumors, retinoblastoma and acute leukemias. This is the case when high dose local radiation therapy and/or chemotherapy, especially alkylating agents, were used. Development of novel primary tumors is also known after treatment of childhood rhabdomyosarcomas. This report is intended to show that a second primary tumor may occur many years after a first successfully treated malignant neoplasm, and that young people are at risk for development of tumors at sites that are uncommon to this age group.
