It is possible for a teratoma to grow in the area of the tailbone.
Teratoma is a common type of ovarian germ cell tumor, which is derived from germ cells. They are divided into mature and immature teratomas.
While the tailbone is located below the sacrum, it is possible to grow teratomas in this area, which are classified as sacrococcygeal teratomas. Teratomas in this area vary in size and are often associated with difficulty in urination and defecation.
Sometimes the patient’s buttocks may be enlarged and there may be a mass in the sacrococcygeal region. The teratoma tends to grow on one side of the buttocks, and all the buttocks often appear asymmetrical.
The specifics of the case need to be determined by a doctor’s visit. If the teratoma grows rapidly and the patient has progressive constipation and urinary difficulties, further examination and surgical excision should be performed to determine the follow-up treatment plan based on the pathological results.
