Background: Birthmarks are common reasons for parents’ concern.
Some of them may need further investigation to find out the
underlying systemic disorders or their potential for malignant
transformation. The purpose of this study was to determine the
frequency of vascular and pigmented birthmarks in infants from
the Northeast of Iran.
Method: This descriptive study was conducted on 1000 healthy
infants born in a University Hospital in the Northeast of Iran from
2003 to 2005. The cutaneous lesions of neonates were examined
by a dermatologist.
Result: The salmon patch was reported as the most common
birthmark (233 cases). The most common site of involvement
was the eyelid. A case of congenital hemangioma and a case of
the port-wine stain were also observed both in the fifth nerve
path. The most common pigmented birthmark was the Mongolian
spot (171 cases). The congenital melanocytic nevus was seen in
50 cases. The lumbosacral area and trunk were reported as the
most common sites of involvement for the Mongolian spot and
congenital melanocytic nevus, respectively.
Conclusion: Fortunately, the most common birthmark is the
salmon patch that is evanescent. The congenital melanocytic
nevus had a relatively high prevalence rate (5%) in comparison
with other studies. Since the appearance of these lesions can
concern parents and there is an increased risk of melanoma in
the cases of congenital melanocytic nevi, follow up is needed in
some cases; we recommend careful examination of the infant’s
skin and training of physicians working in neonatal wards.
