Myxoid tumor explained

A myxoid tumor is a connective tissue tumor with a "myxoid" background, composed of clear, mucoid substance.^[1] This tumoral phenotype is shared by many tumoral entities:

• Myxomas
  • Atrial myxoma
  • Odontogenic myxoma
  • Cutaneous myxoma
  • Intramuscular myxoma
• Myxoid hamartoma
• Aggressive angiomyxoma
• Myxoid leiomyoma
• Chondromyxoid fibroma
• Myxoid neurofibroma
• Nerve sheath myxoma (neurothekeoma)
• Myxolipoma
• Angiomyofibroblastoma
• Myxoid leiomyosarcoma
• Myxoid liposarcoma
• Lipoblastoma
• Myxofibrosarcoma
• Myxoid cortical adenoma
• Pleomorphic adenoma
• Undifferentiated embryonal sarcoma
• Plexiform angiomyxoid myofibroblastic tumor
• Myxoid plexiform fibrohistiocytic tumor
• Angiomyxolipoma (vascular myxolipoma)
• Parachordoma
• Acral myxoinflammatory fibroblastic sarcoma
