Bone Marrow Infiltration by Rhabdomyosarcoma Mimicking Acute Leukemia in an Adult Patient

Rhabdomyosarcoma (RMS) is a rare form of cancer that develops from skeletal muscle, and it rarely occurs in adults. In this report, we present a case study of an adult patient diagnosed with the alveolar subtype of RMS. The patient's condition manifested in an unexpected manner, resulting in significant challenges in terms of diagnosis and treatment. The patient presented at our clinic with a rapidly expanding mass and initial symptoms that resembled those of lymphoma. Following a comprehensive investigation, which included tissue examination, specialized staining, and imaging, the diagnosis of alveolar RMS was confirmed. The patient received a combination of surgery, chemotherapy, and radiotherapy. However, the disease progressed within six months. This case demonstrates the importance of medical professionals considering a wide range of diagnoses for adult soft tissue tumors and the value of interdisciplinary teamwork in achieving optimal patient outcomes.
