Description
Xianlong Wu and four colleagues present a 2026 case report of a newborn boy with a rare condition in which a malformed twin grows inside its sibling's body. The mass sat in the baby's abdomen and was attached to an undescended testis, a pairing the authors call exceptionally uncommon.
Jaundice and a lump led to scans that showed fat, soft tissue, and striped calcified parts, leaving doctors unsure whether the growth was this condition or a teratoma tumor. Surgery removed the mass, and examination found an organised spine plus brain, gut, liver, bone, and skin tissue. That organised structure settled the diagnosis under the classic Willis criterion.
