Neonatal skin provides physical protection and allies in fluid balance, immunosurveillance and thermoregulation, thus playing a crucial role in the newborn’s transition from an aqueous to an air dominant milieau. Quiet large number of changes from transient physiological to grossly pathological lesions are observed in the skin of a neonate. The majority of the disorders in the newborn are physiological, transient and self-limited and majorly require no therapy. Mongolian spot is found as blue, green spot majorly on the shoulders and lower part of the body, scientifically Mongolian spots can be delineated as deep dermal melanocytes present in the collagen bundle. The color is generally the same over the whole birthmark, with no lighter or darker areas as is sometimes seen in brown birthmarks. Mongolian blue spots are can differ in size, but most are a few centimeters across. They can appear anywhere on the body, but are most generally noted at the base of the spine, the buttocks or on the lower back. In addition, they are present on the back of the shoulder. It is very unusual for a child to have a Mongolian blue spot on the scalp or face.

fluid balance, immunosurveillance and thermoregulation,
thus playing a crucial role in the newborn’s transition from
an aqueous to an air dominant milieau. Quiet large number
of changes from transient physiological to grossly
pathological lesions are observed in the skin of a neonate.
The majority of the disorders in the newborn are
physiological, transient and self-limited and majorly require
no therapy. Mongolian spot is found as blue, green spot
majorly on the shoulders and lower part of the body,
scientifically Mongolian spots can be delineated as deep
dermal melanocytes present in the collagen bundle.

3. • INTRODUCTION
• It is a type of birthmark that is present at birth
or may appears soon afterwards, either single
or multiple in number. It is flat, blue-grey in
color and can differ from a very dark blue to a
lighter grey.

4. • The color is generally the same over the whole
birthmark, with no lighter or darker areas as is
sometimes seen in brown birthmarks. Mongolian
blue spots are can differ in size, but most are a
few centimeters across. They can appear
anywhere on the body, but are most generally
noted at the base of the spine, the buttocks or on
the lower back. In addition, they are present on
the back of the shoulder. It is very unusual for a
child to have a Mongolian blue spot on the scalp
or face.

5. • Mongolian Blue Spot
• Mongolian Blue spots have led to a small number of
families being inappropriately referred causing pivotal
distress and inconvenience. Such birth marks are
sometimes not being indicated and in particular are often
not documented in the child records when first seen
(Upshaw et al., 1947) [1].
• Incidence
• Almost universal in non-Caucasian neonates. Specifically
obvious in Asian infants and occasionally also occurs in
Caucasian infants with dark hair.

6. • Clinical State
• Grey or bluish pigmentation, generally in the features lumbosacral
region, but may occur anywhere on the trunk or limbs. Prognosis
Becomes less obvious as the infant grows older (Allen, 1949) [2].
• Erythema Toxicum (Urticaria of Newborn, Eosinophil Rash)
• Incidence
• Extremely common, except in preterm infants. Generally, infants
are affected in first week of life.
• Etiology
• Vesicles are full of eosinophils.
• Clinical Features
• Widespread, fluctuating erythematous maculopapular rash,
generally beginning after birth at any time in the first week.
