A 70-year-old man who visited Samsung Medical Center reported experiencing palpitation for 2 weeks. He had undergone excision of a mass in the right buttock due to rhabdomyosarcoma 7 years prior to this visit. Transesophageal echocardiography showed a pedunculated mass in the left ventricle, which was thought to be a vegetation of infective endocarditis, metastasis of the primary tumor, or thrombus. He underwent removal of the cardiac tumor, and the pathologic report was metastatic rhabdomyosarcoma. Thus, here, we report a rare case of metastatic rhabdomyosarcoma in the left ventricle.

Fine-needle aspiration cytology (FNAC) has been used extensively in the diagnosis of metastatic malignancies. However, metastatic soft tissue sarcomas are often overlooked, primarily due to the low frequency with/ which they occur. Here, we report a rare case of metastatic rhabdomyosarcoma in both cervical lymph nodes, which was detected by FNAC. A 45-year-old woman presented with anosmia, postnasal drip, and sneezing, symptoms which had persisted for 1 month. The patient was found to have a tumorous lesion at the upper portion of the mid-turbinate, with multiple enlarged cervical lymph nodes, and this lesion was examined closely at our facility. FNA cytology smears obtained from both cervical lymph nodes revealed a high degree of cellularity, and displayed cohesive clusters with gland-like spaces, as well as single isolated cells with abundant karyorrhectic debris. The tumor cells exhibited round to oval nuclei containing fine chromatin, occasional small nucleoli, and scanty cytoplasm, or a total lack of cytoplasm. Some of the tumor cells were arranged in multinucleated forms and abundant dense eosinophilic cytoplasms, reminiscent of a rhabdomyoblast. The histological findings on the lymph nodes revealed an outstanding sinusoidal infiltration and a prominent alveolar growth pattern, interspersed with occasional typical rhabdomyoblasts. The immunohistochemical results [desmin (+), myoglobin (+), myogenin (+), pan CK (-), synaptophysin (-), neuron specific enolase (-)] supported a confirmative diagnosis of alveolar rhabdomyosarcoma. Alveolar rhabdomyosarcoma is a representative sarcoma, which typically manifests with nodal metastasis and carcinoma-like clustering. The cytopathologist should remain alert upon encountering unusual morphology, so that the possibility of this condition, although somewhat remote, should not be dismissed or overlooked.

Objectives This study is to report a case on a patient with pulmonary metastatic rhabdomyosarcoma and post-radiotherapy general weakness. This patient's symptoms were improved by the Korean Medicine treatments. Methods The patient was treated for 2 weeks with acupuncture, herbal medicine (Gamisibjeontang, 加味十全湯), and herbal steam therapy. Results NRS and G/A were used to assess patient's symptoms daily morning and to observe the changes of symptoms. After 2 weeks of the treatments, the patient showed remarkable improvement of the main symptoms of general weakness, and pain of the surgical sites. Conclusions This case study showed that post-radiotherapy general weakness symptoms in patient with pulmonary metastatic rhabdomyosarcoma were significantly improved by the Korean medicine treatment, such as acupuncture, herbal medicine, and herbal steam therapy.

It is uncommon for pediatric patients with rhabdomyosarcoma to present with clinical and/or laboratory features of disseminated intravascular coagulation (DIC). We report a case of metastatic alveolar rhabdomyosarcoma with severe bleeding because of DIC in a 13-year-old boy. He experienced persistent oozing at the site of a previous operation, gross hematuria, and massive epistaxis. Two weeks after initiating combination chemotherapy consisting of vincristine, doxorubicin, and cyclophosphamide, the patients' laboratory indications of DIC began to resolve. During this period, the patient received massive blood transfusion of a total of 311 units (26 units of red blood cells, 26 units of fresh frozen plasma, 74 units of platelet concentrates, 17 units of single donor platelets, and 168 units of cryoprecipitate), antithrombin-III and a synthetic protease inhibitor. Despite chemotherapy and radiation therapy, he died 1 year later because of disease progression. In children with metastatic rhabdomyosarcoma and massive DIC, prompt chemotherapy and aggressive supportive care is important to decrease malignancy-triggered procoagulant activities.

Metastasis of rhabdomysarcoma to the breast is a very rare manifestation in adult males. Herein, we report a case of metastasis from embryonal rhabdomyosarcoma in the left hypothenar muscle that presented as a breast mass in a 38-year-old man, who four months later expired because of multiple bone metastases related to pancytopenia. We describe the various imaging findings, including mammograms, ultrasonography, computerized tomography (CT), positron emission tomography-computed tomography (PET-CT), and magnetic resonance imaging (MRI) of this rare disease. The various imaging findings of this lesion could be helpful for future diagnosis of male breast lesions.

Cytologic findings of pleural effusion in three cases of rhabdomyosarcoma are reported. Case 1 was a pleomorphic rhabdomyosarcoma which had devoped at the chest wall of an elderly male patient and caused pleural effusion. The cytologic features were consistent with pleomorphic rhabdomyosarcoma, that was, showing loose clusters, cellular pleomorphism, and abundant finely vesicular cytoplasm. Cases 2 and 3 were embryonal rhabdomyosarcomas in young adults. Primary site was the oral cavity in case 1, but unknown in case 2 and case 3. The effusion cytology was similar in these cases. Clustered or isolated small round cells with hyperchromatic nuclei and scanty cytoplasm were smeared. The cohesiveness of tumor cells was weak and the cells did not show linear arrangement or nuclear melding. Effusion cytology in a sarcoma patient would be diagnostic when the primary site and the type of sarcoma were already known.

We have experienced 49 cases of tumors of chest wall at St. Mary`s Hospital from Jan. 1963 to Dec.1974. In four cases of them, the reconstruction of chest wall defects performed. 1] Out of 49 cases of tumors of the chest wall, 27 cases were benign tumors, 14 cases metastatic malignant tumors, and 8 cases primary malignant tumors. 2] Twenty-six cases [50%] of tumors of the chest wall were on the bony cage. Among them benign tumors were 9 cases [35%], metastatic malignant tumors 14 cases [53%], and primary malignant tumors 3 cases [12%]. Of these, 24 cases were located on the ribs and 2 cases on the sternum.3] The malignant tumors of bony chest wall were excised in en bloc resection including involved ribs. The wide defects of bony chest wall were reconstructed by means of displacement of neighboring ribs and mobilized diaphragm, in the two osteogenic sarcomas of rib, and of prosthesis with silastic sheets in one rhabdomyosarcoma and one metastatic adenocarcinoma of lung.

We describe two cases of metastatic Wilms' tumor in the lung with emphasis on the cytologic features of specimens obtained by needle aspiration. One of them was extrarenal Wilms' tumor. The findings were correlated with the histopathologic features of the primary lesion. Cellular components in the fine needle aspiration cytology (FNAC) slides included blastemal, epithelial, stromal and inflammatory cells with immature tubular differentiation and rosette formation. Recognition of these cellular components in FNAC smears help in establishing FNAC diagnosis of Wilms' tumor. The blastemal cells were represented by small to medium sized cells with scanty cytoplasm having ill-defined borders and round to slightly oval nuclei with evenly dispersed chromatin and small marginated nucleoli. They were seen in our two cases. The differential diagnosis includes neuroblastoma, malignant lymphoma, malignant rhabdoid tumor, clear cell sarcoma, Ewing's sarcoma and embryonal rhabdomyosarcoma. In conclusion, making a definite cytologic diagnosis of metastatic Wilms' tumor may be possible by light and electron microscopy and immunohistochemical staining. The above findings may contribute to the diagnosis of FNAC of metastatic Wilms' tumor.
