Undifferentiated soft-tissue sarcoma (STS) in a 34-year-old woman: A case report

Abstract

Introduction and importance: soft tissue sarcoma (STS) is a type of cancer that can affect connective tissue. Diagnosis of this malignant tumor is difficult, and complications are related to the pressure it can exert on surrounding body organs. Up to 50 % of STS patients develop metastatic disease, which greatly affects the prognosis and is challenging for the treating physician. Case presentation: This case report is about a 34-year-old woman who was found to have significant growth of malignant tumor in her lower back due to misdiagnosis and negligence about her disease. After the cancer invaded the abdominal cavity, she died from related complications. Clinical discussion: STS are among the rare malignant tumors, and the mortality rate of these cancers is very high because they are often not properly diagnosed. Conclusion: Educating medical personnel, especially primary care physicians, about the symptoms and manifestations of STS can make a significant contribution to successful treatment. Due to the complexity of treatment, any soft-tissue swelling suspected of malignancy is best referred directly to a sarcoma center, where therapeutic management is carefully planned by an experienced multidisciplinary team.
