'''Sacrococcygeal teratoma''' (SCT) is a [[teratoma]] (a kind of tumor) located at the base of the [[coccyx]] (tailbone). It is thought to be a derivative of the [[primitive streak]].

At [[birth]], the usual presentation is a visible lump or mass under the skin at the top of the buttocks crease.  If not visible, it can sometimes be felt; gently prodded, it feels somewhat like a hardboiled egg.  A small SCT, if it is entirely inside the body, may not present for years, until it grows large enough to cause pain, constipation and other symptoms of a large mass inside the [[pelvis]], or until it begins to extend out of the pelvis.  Even a relatively large SCT may be missed, if it is internal, because the bony [[pelvis]] conceals and protects it.  [[Mediastinal tumor]]s, including teratomas, are similarly concealed and protected by the [[rib cage]].

Some SCTs are discovered when a child begins to talk at about age 2 years and complains of their bottom hurting or feeling "poopy" when they ride in a car seat.

Overview

History and symptoms

At birth, the usual presentation is a visible lump or mass under the skin at the top of the buttocks crease. If not visible, it can sometimes be felt; gently prodded, it feels somewhat like a hardboiled egg. A small SCT, if it is entirely inside the body, may not present for years, until it grows large enough to cause pain, constipation and other symptoms of a large mass inside the pelvis, or until it begins to extend out of the pelvis. Even a relatively large SCT may be missed, if it is internal, because the bony pelvis conceals and protects it.
