Rhabdomyosarcoma is a rare malignant tumor that is most common among children’s soft tissue sarcomas and occurs in children under 10 years of age. Rhabdomyosarcoma cells develop from abnormally growing early muscle cells and can occur in various parts of the body, commonly in the head and neck, limbs and genitourinary organs. The common initial symptoms are mostly painless lumps, but due to the different parts of the body, there are differences in the specific early symptoms. They are as follows: 1. Tumors growing in the nasal cavity may cause nasal congestion, similar to the symptoms of sinus infection, and may also lead to nosebleeds; 2. Tumors growing in the ear may cause ear pain, bleeding or fluid in the ear canal, and the appearance of lumps in the ear canal; 3. Tumors growing in the inner part of the eye sockets may cause swelling and protrusion of the eyeballs, which may lead to strabismus; 4. Tumors growing in the bladder, urethra, vagina, and testes may lead to urination. Tumors growing in the bladder, urethra, vagina, testicles and other parts of the body may cause difficulty in urination, hematuria, vaginal bleeding, and masses may be found in the vagina or around the testicles; 5. Tumors growing in the abdominal cavity or pelvic cavity may cause abdominal pain, vomiting and constipation; 6. Tumors growing in the limbs are usually manifested as lumps in limb areas, and localized pains in the limbs may occur. When tumor metastasis occurs, different clinical symptoms may appear if the metastatic sites are different. Lung metastasis may present chronic cough, coughing up blood, etc. Bone metastasis may present bone pain, lymph node metastasis may present enlarged lymph nodes, bone marrow metastasis may present anemia. Non-specific symptoms such as weakness and weight loss can also occur.
