Background: Rhabdomyosarcoma (RMS) is a malignant soft tissue tumor that accounts for approximately one-half of soft tissue sarcomas in childhood age groups. Metastatic RMS is a rare condition that occurs in less than 25% of patients at diagnosis and can have variable clinical presentations.
Case presentation: Here we report a 17-year-old boy with history of weight loss, fever and generalized bone pain admitted for severe hypercalcemia. The definite diagnosis of RMS was performed with immune-phenotyping of the metastatic lymph-node biopsy. The primary tumor site was not found. His bone scan showed diffuse bone metastasis and significant soft tissue technetium uptake due to extra-osseous calcification.
Conclusion: Metastatic RMS can mimic lymphoproliferative disorders at presentation. Clinicians must be aware of this diagnosis especially in young adults.
期刊介绍：
This online-only journal publishes original case reports on all types of cancer. In particular, we welcome not only case reports of educational value in the diagnosis and treatment of cancers, but also reports on molecularly analyzed cancer cases, including gene mutations, gene fusions, gene expression, and changes in copy number, regardless of their known clinical significance. Assessing the molecular analysis of a tumor usually requires a “cancer conference” in which experts from various fields discuss it. Even if the authors and their respective “cancer conference” were unable to determine the clinical significance of molecular changes at the time of submission and publication, their data may provide evidence that will help the scientific community develop precision medicine solutions in the future. We welcome case reports with reviews of the literature on similar cases, as they are more useful and valuable to readers than are reports of rare cases. International Cancer Conference Journal is the official publication of the Japan Society of Clinical Oncology (JSCO).
