Sacrococcygeal teratoma is a germ cell tumor that develops at the base of the tailbone, often presenting as a visible mass at birth or detected via prenatal ultrasound. The primary symptoms range from a palpable, external lump to complications involving pressure on surrounding organs, requiring careful clinical monitoring and specialized surgical management. What are the primary symptoms of Sacrococcygeal Teratoma? The most characteristic sign of Sacrococcygeal teratoma is a noticeable mass protruding from the sacrococcygeal region.

Sacrococcygeal teratoma is a germ cell tumor that develops at the base of the tailbone, often presenting as a visible mass at birth or detected via prenatal ultrasound. The primary symptoms range from a palpable, external lump to complications involving pressure on surrounding organs, requiring careful clinical monitoring and specialized surgical management.
The most characteristic sign of Sacrococcygeal teratoma is a noticeable mass protruding from the sacrococcygeal region. Because these tumors can grow rapidly, they may cause symptoms related to their size and location, including:
The severity of Sacrococcygeal teratoma symptoms often depends on the tumor's size and its classification (Altman classification types I through IV). Type I tumors are predominantly external, while Type IV tumors are entirely internal within the pelvis, making them more difficult to detect early. Over time, if left untreated, the tumor can grow, potentially leading to high-output cardiac failure in the fetus due to the significant blood flow required by the mass.
Immediate medical intervention is necessary if a newborn with Sacrococcygeal teratoma exhibits signs of respiratory distress, severe abdominal distension, or neurological deficits in the lower limbs. Any sudden change in the size or firmness of the mass, or signs of skin ulceration, requires an urgent evaluation by a pediatric surgeon or neonatologist.
For the 40 members of our DiseaseMaps.org community living with or affected by Sacrococcygeal teratoma, the journey often involves long-term follow-up to monitor for recurrence. Even after successful excision, patients may experience long-term challenges related to pelvic floor function or bowel/bladder management, which can significantly impact daily quality of life and require multidisciplinary support.
