Yes, and absorbed twin can be a teratoma. I know this because when I was 15 I had a teratoma. The doctor explained to me that I had absorbed my twin while my mother was pregnant with me. If you think you have a teratoma PLEASE see a doctor immediately! My teratome was not noticeable and then i started to see my stomach grow as if I were pregnant. By the time I saw a doctor mine was the size of a basketball. If i had waited maybe a month later it would've grown and taken over my vital organs and my life.
