This study was performed to investigate the rate of occurrence of neonatal birthmarks and their clinical features. From October 1982 to September l983, 1,035 newborn babies were examined in the Keimyung University Dongsan Medical center and the results were summarized as follows. The main nevi in the newborn were salmon patch (28 9%), portwine stain (0.3%), strawberry mark (0.4%), pigmented lesions (1.0%) and mongolian spot (81. 2%). The salmon patch was present most frequently on the nape but no particular predilection sites were noted in portwine stain, strawberry mark and pigmented lesions. The mongolian spot developed on the sacral portion, buttocks and lower back, in decreasing order.

Dermal melanocytosis is characterized by the presence of ectopic melanocytes in the dermis. The most common forms include the Mongolian spot, blue nevus, nevus of Ota, and nevus of Ito. Some types of dermal melanocytosis do not fit into any of these morphologic categories, however. Our case demonstrated an extensive amount of uniform deep blue patches of nevi with unilateral distribution on the left face, neck, chest, shoulder, and back. On histopathologic examination, a number of elongated melanocytes scattered throughout the dermis were found. We herein report a case of congenital unilateral dermal melanocytosis.

Dermal melanocytosis includes Mongolian spot, nevi of Ota and Ito, dermal melanocytic harnartoma, and blue nevus. Nevi of Ota may be respectively associated with Mongolian spot, blue nevi and unilateral or bilateral nevi of Ito. We present a case, a 24 year-old female, who had bilaterally brownish or slatebluish pigmented patches on the face, sclera, neck, anterior chest, deltoid, supraclavicular, scapular, back and sacrococcygeal area. And also she had a bluish, bean-sized nodule on her left mid-back. It is likely that this case may be considered as an extremely extensive case of pig:m.entary anomaly, associating aberrant and persistent mongolian spots, extensive nevus of Ito, bilateral nevus of Ota and blue nevus. To our knowledges it seems that such case has not previously been reported in Korean literature.

This study was performed in the Korean recruits to determine the prevalence and the sites of predilection of the nevi involving melanocytes. The results were summarized as follows; 1) 411 of 2311(17. 7%) recruits examined were found to have nevus spilus, most prevalent in the trunk. The lesions were usually solitary but occasionally two or three lesions were found in a single individual. The prevalence of speckled lentiginous nevus was 0.49%,(2l/4247). The site of prevalence of progressive cribriform and zosteriform hyperpigmentation was 0. 80% (34/4247). The lesions were most commonly observed in the lower trunk and upper thighs. 4) The prevalence of Becker's nevus was 0.45%(19/4247). The lesions were most commonly observed in the shoulder and its surrounding areas. 5) Persistent Mongolian spot were observed in 2. 73% (63/2311). The proportion of extrasacral spots to sacral spots was increased to almost half of the entire spots. 6) Blue nevi were observed in 0. 48M (11/2311), most frequently in the sacral area.

We observed the neonatal skin to investigate the incidence and clinical features of birthrnarks. We examined 1791 newborn babies admitted in the nursery of Kangnam Sacred Heart Hospital from July 1987 to July 1989. The results were summarized as follows. 1. Mongolian spots were observed in 1435 neonates (80.1%), occurring most frequently on the lumbosacral area. 2. Salmon patches were observed in 416 neonates (23.2%), the nape of neck being the most common site. 3. Pigmented lesions were observed in 20 neonates (1.1%). 4. Portwine stains were observed in 15 neonates (0.8%). 5. Epidermal nevi were observed in 4 neonates (0.2%) and nevus sebaceus developed in one baby.

Benign pigmented lesions derived from dermal melanocytes include the Mongolian spot, the nevi of Ota and Ito, and the blue nevus. The nevus of Ito differs from the nevus of Ota by its location in the supraclavicular, scapular and deltoid regions. It occurs rarely in association with bilateral nevus of Ota. We present a 70 years old male, showing extensive involvement of dermal melanocytic nevi, so called bilateral nevus of Ota associated with bilateral nevus of Ito.

This survey was made on 1462 cases in different age groups, from the neonate to the age of 15, to analyse the data statistically concerning the prevalence, size, shape, site and color of Mongolian spot. The results were as follows: 1) Of 1462 cases, Mongolian spot(s) was(were) present in 759(51. 9%) with the sex ratio of male to female, 1: l. 2. The prevalence could be divided into 3 stages, high(neonate to 3years), abruptly declined(4 to 9year), steadily declined (10 to 15years) 2) The mean and standard deviation of diameter represented 4. 56+2. 96cm(M +SD), ranging from 0. 5 to 21 cm. 3) The two most common shapes were ovoid(45. 5%,) and irregularly circular (31.4%). 4) The two most common sites were sacrococcygeal(80. 1%,) and gluteal(75. 1%). 5) The two most common colors were blue(75. 1 %) and purple-blue(13. 5%).

Dermal melanocytosis such as nevus of Ota and extensive Mongolian spots are sometimes associated with hemangiomatous changes. Ota gave the designation of phakorriatosis pigmentovascularis to a spectrum of these combinations. We oLserved four cases of phakomatosis pigmentovascularis. They showed extensive, various dermal melanocytosis and widespread nevus flammeus. They exhibited signs of involvement of the systemic organs such as abnormality of electroencephalograrn, soft tissue hypertrophy and convulsion.
