Abstract
BACKGROUND Aplasia cutis congenita (ACC) is a rare congenital malformation characterized by a localized absence of skin. which most commonly affects the scalp. We performed the present study to elucidate the basic clinical data regarding ACC in Korea, including demographics, clinical features, radiological and therapeutic results. METHODS Fifty-nine patients (70 lesions) with ACC (35 from our department and 24 from a Koreamed database search) were enrolled. We assessed demographics, family and obstetrical histories, clinical features (multiplicity, subtype, size, shape, hair collar sign, location, and Frieden's classification), and radiologic and therapeutic results. RESULTS The mean age of patients was 2.62 years, with a male-to-female ratio of 1.03. A minority of patients had a family history (three patients), birth trauma (one patient), maternal drug use (two patients), or human immunodeficiency virus infection (one patient) during pregnancy, and fetus papyraceus of placental infarcts (two patients). Six patients (6/59, 10.17%) had multiple lesions. Scarring was the most common manifestation (39/70, 55.71%). The scalp was the most commonly affected site (50 cases, 71.43%). Thirty-nine patients (66.10%) met Frieden's type I classification (scalp ACC without multiple anomalies). Radiological investigations were performed in 30 patients (30/59, 50.85%) with abnormal findings in eight patients. Twenty-five patients (42.37%) were managed conservatively, and 17 patients (28.81%) were treated with local wound care. CONCLUSIONS This is the first and largest study assessing the basic clinical data of ACC in Korea. The results of the present study could be useful for pediatricians and dermatologists who routinely manage ACC.

Abstract
Background: Aplasia cutis congenita (ACC) is a part of a heterogeneous group of conditions characterized by the congenital absence of epidermis, dermis, and in some cases, subcutaneous tissues or bone usually involving the scalp vertex. There is an estimated incidence of 3 in 10,000 births resulting in a total number of 500 reported cases to date. The lesions may occur on every body surface although localized scalp lesions form the most frequent pattern (70%). Complete aplasia involving bone defects occurs in approximately 20% of cases. ACC can occur as an isolated defect or can be associated with a number of other congenital anomalies such as limb anomalies or embryologic malformations. In patients with large scalp and skull defects, there is increased risk of infection and bleeding along with increased mortality and therefore prompt and effective management is advised. Case Description: We describe two cases of ACC, involving a 4 × 3 cm defect managed conservatively and a larger 10 × 5 cm defect managed surgically with the use of a temporo-occipital scalp flap. Both cases had an excellent outcome. Conclusions: Multiple treatment regimens exist for ACC, but there is no consensus on treatment strategies. Conservative treatment has been described and advocated, but many authors have emphasized the disadvantages of this treatment modality. Decision between conservative and surgical management must be individualized according to lesion size and location.

Abstract
BACKGROUND/AIMS The object of this report is to review the management of patients having the composite type of aplasia cutis congenita in the context of the relevant literature on this condition. METHODS Clinical records, neuroimaging and photographic documentation of identified cases of composite type aplasia cutis congenita, with a comprehensive review of the literature, are the material basis of this report. RESULTS Two neonates with composite type aplasia cutis congenita are described as examples of this disorder, and their management, including complications, is discussed. Both had satisfactory outcomes. CONCLUSIONS Early aggressive surgical management with scalp rotation flaps has a low rate of complications, provides satisfactory functional and esthetic outcome, minimizes hospital stays, and should provide cost-effective care by reduction of the time to secure wound closure. Most bony defects, even large ones, commonly ossify completely. Optimal case management requires a synchronized neurosurgical and plastic surgical team. Intuitive nonsurgical and surgical approaches by the inexperienced can be hazardous.

Abstract
The authors report a case of a female baby born with large congenital scalp and skull defects with exposure of the cranial arachnoid mater. The female patient was delivered by Caesarean section following diagnosis of a large cranial skin defect by ultrasound. The skin defect was present at the time of birth, measured 8.5 cm × 8.0 cm, and involved the full thickness of the cranium. The cranial arachnoid mater was exposed and veins running on the surface of the brain were observed. There was no means to cover the large defect surgically and conservative treatment was initiated. Complete epithelialization of the scalp defect was acquired without fatal problems. In the course of treatment, Mepilex Transfer was very effective. The repair of congenital defects of the scalp and skull is a major challenge not only because of the rarity but also because of severe morbidity. A surgical or conservative approach is chosen according to the situation. This rare case highlights two important clinical issues: that the congenital defects of the scalp and skull could not be managed with a surgical approach and in its place, a conservative approach using the special dressing Mepilex Transfer proved highly effective.

Abstract
The main aim of this study was the comparative evaluation of fibroin scaffolds combined with human stem cells, such as dental pulp stem cells (hDPSCs) and amniotic fluid stem cells (hAFSCs), used to repair critical-size cranial bone defects in immunocompromised rats. Two symmetric full-thickness cranial defects on each parietal region of rats have been replenished with silk fibroin scaffolds with or without preseeded stem cells addressed toward osteogenic lineage in vitro. Animals were euthanized after 4 weeks postoperatively and cranial tissue samples were taken for histological analysis. The presence of human cells in the new-formed bone was confirmed by confocal analysis with an antibody directed to a human mitochondrial protein. Fibroin scaffolds induced mature bone formation and defect correction, with higher bone amount produced by hAFSC-seeded scaffolds. Our findings demonstrated the strong potential of stem cells/fibroin bioengineered constructs for correcting large cranial defects in animal model and is likely a promising approach for the reconstruction of human large skeletal defects in craniofacial surgery.

Abstract
Aplasia cutis congenita is characterised by congenital absence of all layers of skin, and most commonly affects the scalp. It is often associated with absence of the bone and dura underlining the defective scalp. In this report, we present the result of use of a water-vapour permeable polyurethane film (Omiderm) together with absorbant fine mesh gauze impregnated with 3% bismuth tribromophenate (Xeroform) in the treatment of a cranial defect in a newborn baby of low birth weight, who could not be operated on because of associated medical problems.

Abstract
UNLABELLED Aplasia cutis is a congenital absence of the skin, usually presenting on the scalp. In 20% of all cases, part of the skull is also absent. A residual area of baldness may still be present some years after surgical or conservative treatment. It is possible to excise the scarred hairless region and cover that area with expanded hair-bearing skin from the rest of the skull. We present three patients who underwent tissue expansion and discuss the indications and pitfalls of this procedure. CONCLUSION Tissue expansion can be used to cover a residual alopecia defect in young children with aplasia cutis congenita and associated bone abnormalities. The quality of the bone appears to be normal in our three patients. We demonstrate that even in young children with aplasia cutis and an underlying bony defect, tissue expansion is a safe and effective modality as a second stage reconstruction procedure.

Abstract
The main aim of this study is to evaluate the capacity of human dental pulp stem cells (hDPSC), isolated from deciduous teeth, to reconstruct large-sized cranial bone defects in nonimmunosuppressed (NIS) rats. To our knowledge, these cells were not used before in similar experiments. We performed two symmetric full-thickness cranial defects (5 x 8 mm) on each parietal region of eight NIS rats. In six of them, the left side was supplied with collagen membrane only and the right side (RS) with collagen membrane and hDPSC. In two rats, the RS had collagen membrane only and nothing was added at the left side (controls). Cells were used after in vitro characterization as mesenchymal cells. Animals were euthanized at 7, 20, 30, 60, and 120 days postoperatively and cranial tissue samples were taken from the defects for histologic analysis. Analysis of the presence of human cells in the new bone was confirmed by molecular analysis. The hDPSC lineage was positive for the four mesenchymal cell markers tested and showed osteogenic, adipogenic, and myogenic in vitro differentiation. We observed bone formation 1 month after surgery in both sides, but a more mature bone was present in the RS. Human DNA was polymerase chain reaction-amplified only at the RS, indicating that this new bone had human cells. The use of hDPSC in NIS rats did not cause any graft rejection. Our findings suggest that hDPSC is an additional cell resource for correcting large cranial defects in rats and constitutes a promising model for reconstruction of human large cranial defects in craniofacial surgery.

Abstract
Aplasia cutis is a rare skin defect usually presenting over the vertex of the skull. An underlying bone defect is found in approximately 20% of patients. Most skull defects close spontaneously. However, when there are no signs of ossification, closure is mandatory. We present our experience in three patients. Our first patient had an aplasia cutis with a skull defect. The split rib graft procedure was used without complications, and a good cosmetic and functional result was achieved. The second patient was operated on for cerebral bleeding after an arteriovenous aneurysm, and a bony defect could not be closed after that procedure. At a later stage, the defect was filled with split rib grafts, and sufficient protection was achieved and documented after more than 30 years. The third patient was born with an aplasia cutis congenita with a skull defect. The bony defect was filled with split rib grafts without complications at an age of 5 years. Follow-up shows a functional result with a firm skull. Patients with aplasia cutis may have skull defects that will not close by themselves. We present three patients with a bony defect who were reconstructed with split rib grafts. After a long period of follow-up, there remains good cosmetic and functional results. Defects of the skull in children can be reconstructed with split rib grafts that will accommodate the growing skeleton and give good protection of the brain from an early age on.

Abstract
Aplasia cutis congenita is a rare condition characterized by congenital absence of the epidermis, dermis, and subcutaneous tissue. It may occur as an isolated defect or associated with other anomalies. This study sought to determine the frequency of this condition over a 10-year-period at the single hospital for a well-defined population. A literature review of potential mechanisms implicated in the development of this condition was also conducted. A retrospective review of all case records of patients diagnosed with aplasia cutis congenita between January 1994 and December 2003 at Hospital Xeral-Calde, in the Lugo region of northwest Spain was undertaken. During the period of study four patients were diagnosed with this condition. Three of them were of the gypsy race. These three had aplasia cutis congenita associated with epidermolysis bullosa and deformed nails. The incidence of aplasia cutis congenita in our region was 2.8 cases per 10,000 newborns. It was found that the incidence of this disorder in northwest Spain was similar to that described in the literature. Careful study due to the frequent association of aplasia cutis congenita with other congenital anomalies and a complete obstetric and family history of all affected individuals are required to identify possible specific teratogens, intrauterine infections, chromosomal abnormalities, or history of this condition among relatives.

Abstract
Surgical treatment of the lesions of the scalp in children has specific objectives: excision of an extensive lesion using minimum operative procedures, hiding scar in the hair, correcting a wide and ungraceful scar. We reviewed our experience of 450 cases (1990-2000), and found that most common lesions in childhood were: sebaceous hamartoma, pigmentary naevus, post traumatic alopecia, aplasia cutis congenita and complicated hemangiomas. Different surgical procedures are discussed: excision, tissue expansion, hair grafts. Large excision can be performed before three months of life because of the good laxity of the scalp. Tissue expansion is particularly suited to the scalp. Aplasia cutis congenita is a special condition, with local vascular abnormalities: local flaps are prohibited. Hemangiomas may require early surgical treatment in the event of complications.

The association of intestinal lymphangiectasia and aplasia cutis, and the association of intestinal lymphangiectasia with brain heterotopia in the lymphedema-lymphangiectasia-mental retardation syndrome have been described in single reports. In one family, the association of cortical dysplasia and congenital lymphedema have been related to mutations in the RELN gene.

Abstract
Congenital defects of the scalp and skull present a challenge for care providers because of a combination of their rarity and the magnitude of potential morbidity. Recent advancements in autogenous and alloplastic cranioplasty and scalp reconstruction techniques argue for a comprehensive consideration of this problem. This article (1) reviews the causes of congenital scalp and calvarial defects; (2) proposes a classification system based on defect type, similar to the tumor-node-metastasis classification, in that defect location, defect size, and extent of neuromeningeal involvement are the critical variables; and (3) presents algorithms for care based on the defect classification. A set of management principles on which treatment plans can be based for these unique problems is provided.

Abstract
Aplasia cutis is one of the features of the Adams-Oliver syndrome, beside limb anomalies. Aplasia cutis, congenital absence of skin, is a lesion that usually presents over the vertex of the skull. Management of aplasia cutis depends on the size of the skin defect and the child's physical condition. Scalp defects larger than approximately 1 cm should be treated surgically. In patients with aplasia cutis, surgery should preferably be performed using rotation scalp flaps, and additional split skin grafts. The history of two babies with the Adams-Oliver syndrome is presented. In the Adams-Oliver syndrome, large rotation scalp flaps are not reliable due to the abnormal vascularity of the skin. Skin grafting is the safest way, preventing hemorrhage and infection, in the operative treatment of aplasia cutis in these babies.

Abstract
Glucocorticoids (GCs) are potent inhibitors of epidermal proliferation and effective anti-inflammatory compounds, which make them the drug of choice for a wide range of inflammatory and hyperproliferative skin disorders. GC action is mediated via the glucocorticoid receptor (GR). To study the role of GR in skin development and the molecular mechanisms underlying its action, we generated transgenic mice overexpressing GR in epidermis and other stratified epithelia, under the control of the keratin K5 promoter. Newborn mice show altered skin development, manifested as variable-sized skin lesions that range from epidermal hypoplasia and underdeveloped dysplastic hair follicles to a complete absence of this tissue. In the most affected individuals, skin was absent at the cranial and umbilical regions, and the vibrissae and eyebrows appear scarce, short, and curly. In addition, as a consequence of transgene expression in other ectodermally derived epithelia, K5-GR mice exhibited further abnormalities that strikingly resemble the clinical findings in patients with ectodermal dysplasia, which includes aplasia cutis congenita. In adult transgenic skin, topical application of the tumor promoter TPA did not elicit hyperplasia or transcriptional induction of several proinflammatory cytokines. This anti-inflammatory role of GR was due at least in part to interference with NF-kB, leading to a strong reduction in the kB-binding activity without altering the transcriptional levels of the inhibitor IkBa.

Abstract
A newborn boy with aplasia cutis congenita had biliary atresia, distal duodenal atresia, and a severe infarct of the intestine resulting in complete absence of the entire midgut. The boy died due to biliary atresia and severe short gut syndrome approximately 3 weeks after birth. While the association of duodenal atresia with aplasia cutis congenita has been described, the findings of biliary atresia and midgut atresia in association with aplasia cutis congenita have not been described previously.

Abstract
Surgical procedures on the skin are commonplace in the practice of pediatric dermatology. Dermatologists are trained in their residencies to perform office surgery, including biopsies, excisions with repairs, cryosurgery, chemosurgery, and laser surgery. Although most dermatologists treat patients of all ages, some treat children only. Within this group, some are concentrating on pediatric dermatologic surgery. Many dermatologists take additional training in dermatologic and laser surgery, treating both adults and children. New techniques and developing technology present pediatricians and dermatologists with many options in choosing the best and most appropriate treatment modalities.
