Others say it is because the baby does not want to leave the mothers womb, so Songzi Guanyin will kick it out, leaving the bruise. A small portion of people wrongfully believe it is caused when the doctor is slapping the babys backside to make it cry. Scientifically, it is also referred to as "蒙古斑" (Pinyin: Měng Gǔ Bān; literally: mongolian spot)
In Khmer, it is known as "khnau" (ខ្នៅ) which translates to Mongolian spot as well as other skin conditions such as vitiligo and leucoderma.The mark is also common among Maya people of the Yucatan Peninsula where is referred to as Wa in Maya, which means "circle". In Ecuador, the native Indians of Colta are insultingly referred to in Spanish by a number of terms which allude to the slate grey nevus.In Spanish it is called mancha mongólica and mancha de Baelz (see Erwin Bälz).In Iñupiaq, is it called auttaq or auktaq, which relates to the word for blood and also means mole.

Prevention
DNA-based tissue typing allows for more precise HLA matching between donors and transplant patients, which has been proven to reduce the incidence and severity of GvHD and to increase long-term survival. The T-cells of umbilical cord blood (UCB) have an inherent immunological immaturity, and the use of UCB stem cells in unrelated donor transplants has a reduced incidence and severity of GvHD. Methotrexate, cyclosporin and tacrolimus are common drugs used for GvHD prophylaxis. Further research is necessary to evaluate whether mesenchymal stromal cells can also be used for the prophylaxis. Graft-versus-host disease can largely be avoided by performing a T-cell-depleted bone marrow transplant. However, these types of transplants come at a cost of diminished graft-versus-tumor effect, greater risk of engraftment failure, or cancer relapse, and general immunodeficiency, resulting in a patient more susceptible to viral, bacterial, and fungal infection. In a multi-center study, disease-free survival at 3 years was not different between T cell-depleted and T cell-replete transplants. Treatment
Intravenously administered glucocorticoids, such as prednisone, are the standard of care in acute GvHD and chronic GVHD. The use of these glucocorticoids is designed to suppress the T-cell-mediated immune onslaught on the host tissues; however, in high doses, this immune-suppression raises the risk of infections and cancer relapse. Therefore, it is desirable to taper off the post-transplant high-level steroid doses to lower levels, at which point the appearance of mild GVHD may be welcome, especially in HLA mis-matched patients, as it is typically associated with a graft-versus-tumor effect.. Cyclosporine and tacrolimus are calcineurin inhibitors.
