What is cutaneous mixed tumor?

summary

Mixed tumor is a kind of tumor formed by two or more new biological tissue structures, which is called mixed tumor. Such as teratoma, nephroblastoma, carcinosarcoma and oral and maxillofacial benign tumors. What is cutaneous mixed tumor? Let's talk about it

What is cutaneous mixed tumor?

Malignant teratomas are mostly solid, more common in the testis than in the ovary. It is mainly composed of immature embryoid tissue and often has poorly differentiated neuroectodermal components, so it is also called immature teratoma. The tumor often metastasizes to the pelvis and distant organs.

Carcinosarcoma is a tumor with both cancer and sarcoma. The components of carcinoma include squamous cell carcinoma, transitional cell carcinoma, adenocarcinoma and poorly differentiated carcinoma; Sarcomas can be divided into fibrosarcoma, leiomyosarcoma, rhabdomyosarcoma, osteosarcoma and chondrosarcoma.

The components of cancer and sarcoma can be mixed in different proportions, usually containing one component of cancer and sarcoma, and occasionally more than one component, such as adenocarcinoma mixed with leiomyosarcoma and osteosarcoma. Carcinosarcoma can occur in many forms, such as epithelial tissue and mesenchymal tissue malignant transformation at the same time, pluripotent stem cells differentiate into cancer and sarcoma; Cancer induces malignant transformation of stroma; Some of the cancer cells developed mesenchymal metaplasia and malignant transformation.

matters needing attention

The best choice for the treatment of this disease is surgical resection. During the operation, the contents of the capsule should be removed as much as possible, and the wall of the capsule should be removed as much as possible. For malignant teratoma in spinal canal, the comprehensive treatment of postoperative adjuvant radiotherapy or chemotherapy remains to be further studied.
