Haematopoietic bone marrow and bony trabeculae: An uncommon mesodermal derivative in mature teratoma in a 14 year old girl

Teratomas are embryonal tumours that emerge when totipotent germ cells evade the primary organisers' control over their growth and give rise to contain tissue from all three layers. They cystic or solid, with mature immature components. Histologically, teratomas classified as (benign in 95% of cases) malignant transformation. rare a frequency 1 10,000 births. located more often sacrococcygeal region, ovary, cervical localization represents 1.5% 5% localizations. predominate among females. Mesodermal derivatives relatively rare, solitary organic development, especially mesodermal derivation random teratoma, is unique crucial distinguish for clinical reasons. Here, we present 14-year-old female who presented submental swelling that, on histopathology, was diagnosed teratoma hemopoietic bony trabeculae.
