The clinical symptoms of clear cell sarcoma are mainly localized lumps and pain. Clear cell sarcoma is a rare malignant tumor that originates from mesenchymal tissues and has different biological characteristics than carcinomas of epithelial origin. The most common clinical symptom of clear cell sarcoma is a localized mass, which is often hard and difficult to push, and some patients may have superficial vasodilatation. Peripheral invasion of clear cell sarcoma can lead to pain, especially in patients who are in close proximity to nerves and bones, which is more pronounced and interferes with sleep. When clear cell sarcoma shows obvious clinical symptoms, the lesion is often large and treatment is relatively difficult, so early detection and early treatment can achieve better results.
