Paratesticular embryonal rhabdomyosarcoma (RMS) is a rare tumor arising from the mesenchymal tissues of the spermatic cord, epididymis, testis and testicular tunics. We report three cases of adult paratesticular RMS, two embryonic and one pleomorphic rhabdomyosarcoma. All the patients underwent diagnostic orchidectomy. The work up investigations revealed lung metastases. Chemotherapy with Ifosfamide and Doxorubicin was used in two cases, whereas Vincristin- Actinomycin D and Cyclophosphamide was received in one case. An objective partial response was reported in 2 cases, with complete response in one case. Paratesticular RMS is a rare and aggressive tumor. Because of the absence of protocols designed specifically for adult patients, it is necessary to follow therapeutic guidelines in pediatric protocols.
The finding on imaging (computed tomography scan or magnetic resonance imaging) of synchronous malignant renal mass in patient with an active nonrenal malignancy without renal specific symptoms is not frequent and diagnostic evaluation can be challenging. We describe a 54-year-old Moroccan male former chronic smoker who presented to our hospital with dry cough and impairment of the performance status. The imaging found a tumor mass in the left upper lobe of the lung associated to mediastinal lymph node and a scanno-guided biopsy of this tumor showed a non small cell lung cancer. The radiological staging revealed a solitary renal mass in the right kidney. The patient received firstly two cycles of a lung cancer chemotherapy with a partial response in the lung and a stability of the renal mass. Consequently, he underwent a scanno-guided biopsy of this mass which confirmed a synchronous clear cell renal carcinoma. The patient got chemo radiotherapy for the lung cancer and then after that he got a partial nephrectomy. He is still under a good control with more than 2 years after the initial diagnosis.
Introduction: Primary embryonal rhabdomyosarcoma of prostate (ERMP) is an extremely rare pathological and clinical entity in adults. It's characterized by extensive loco-regional spread and a tendency to metastasize by blood stream and regional lymphatics. In adult patients, data available on the management of ERMP are limited and mostly derived from the pediatric clinical trials on rhabdomyosarcoma. Case Report: We report a case of group III ERMP approached by initial surgery followed by the administration of three courses of vincristine, doxorubicin and Cyclophosphamide regimen. The patient succumbed to disease complications three months after the original diagnosis. Conclusion: The most appropriate therapeutic approach for adults with ERMP remains questionable. Further studies are needed to improve the understanding of biological behavior of ERMP in adults and to define the best therapeutic strategy in locally advanced disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
