A parent of a male newborn was presented to us with the complaint of skin defect over the trunk. The baby was term with birth weight of 2.6 kg and product of nonconsanguineous marriage. The baby was the second child for the parents without any demise. Antenatal history was unremarkable with single live fetus and without fetus papyraceous. There was no history of any in vitro fertilization, multiple pregnancy, and abortion. On examination, there was skin defect involving the lower chest and upper abdomen bilateral symmetrically without any discharge [Figure 1]. There were thin transparent membranes on both sides, and ribs were visible under the defect. These were full-thickness defect with the involvement of muscles bilaterally. The size of defect was 10 cm × 6 cm on both sides. Both defects were connected by a band-like defect. There were no other organ abnormalities. Routine blood investigations were within normal limits including complete blood count, renal function test, serum electrolytes, and liver function test. Chest X-ray and abdomen were normal. Ultrasonography abdomen and echocardiography were normal. Affected area was treated by mupirocin and Vitamin A + D ointment. The patient was lost to follow-up, so could not comment on the results.
Aplasia cutis congenita (ACC) is an uncommon disorder presented at birth, which commonly involves the skin of the scalp and other areas but may involve the subcutaneous tissue, bone, and dura mater. The most common presentation is the solitary lesion on the scalp, but in our case, the lesion was on the trunk. The cause is not clear, but numerous factors have been considered as possible causes of ACC, including placental infarcts, genetics, teratogenic substances, intrauterine infections and trauma, vascular compromise, amniogenesis, adhesions of the amniotic membrane to the fetal skin, amniotic rupture sequence, ectodermal dysplasia, imperfect neural tube closure, and maternal intrapartum drug use. The recent increase in the use of in vitro fertilization techniques has caused a marked rise in the incidence of multiple gestation pregnancies.
The cause of the symmetrical type of aplasia cutis is a vascular disruption inducing abnormal dermoepidermal development or cutaneous defect through ischemic and thrombotic events. The intrauterine death of one of the fetuses should cause the release of the thrombosis-promoting material from the dead fetus. These substances can cause placental infarction, disseminated intravascular coagulation, and cutaneous lesions.
Other abnormalities such as hepatic hematoma, duodenal atresia, and biliary atresia may be observed. These findings prove hypothesis of the vascular origin of the disorder. Our patient did not have any other organ abnormalities.
It is seen after fetus papyraceous in multiple pregnancies. Whereas, in our case, there is no such finding. Affected patients show linear areas of absence of skin that have bilateral pattern of distribution along the flanks and the lateral aspect of the limbs. Therefore, prenatal ultrasound has been a great help in allowing a better understanding of this disorder. However, in our case, prenatal ultrasound was normal. In familial cases, genetic counseling is needed. Prenatal diagnosis through amniocentesis and chorionic villous sampling can be helpful to rule out junctional and dystrophic epidermolysis bullosa.
Besides isolated presentation, it may manifest with other developmental malformations of cardiovascular, gastrointestinal, genitourinary, and central nervous systems (CNSs), and syndromes such as Adams–Oliver syndrome, SCALP syndrome (nevus sebaceus, CNS malformations, ACC, limbal dermoid, and pigmented nevus), Opitz syndrome, and chromosomal disorders are associated with this lesion.
Histological details are available in very few reports. Histological features vary depending on the depth and duration of aplasia. Ulcers are seen at birth. After healing, the epidermis appears flattened with proliferation of fibroblasts within a connective tissue stroma. Total absence of the epidermal appendages remains a characteristic feature.
Conservative treatment is the most popular regimen. Although there have been reports of the surgical treatment of ACC, the use of the scalp as a donor site has rarely been reported.
An ACC scalp defect can be an indicator of internal organ involvement and increase the risk of complications. The occurrence of complications can increase the likelihood of a poor outcome. Attention should be paid to the prevention and treatment of complications such as infection, bleeding, electrolyte imbalance from increased epidermal water loss, nutritional deficiency from chronic blood loss, and pain at wound dressing.
The selection of treatment depends on the condition of the infant and the complications that occur. Multiple treatment regimens have been reported for cases of ACC.
Cerebral damage, bleeding, and infections should be carefully monitored when the patient is being conservatively treated with dressing changes. A multidisciplinary approach can be useful. Treatment for ACC is currently controversial and may be conservative, including dressings, surgery, or a combination of both. There are a range of conservative dressing options, such as moist dressing, burn cream, dressing with silver sulfadiazine cream, and dressings containing epidermal growth factor. Skin grafting and local flaps are the predominant surgical treatment options for ACC. Skin graft is recommended for large facial defects that are at risk of sagittal sinus thrombosis and cerebral hemorrhage. Surgical management should be selected for large and deep lesions that are not healed through conservative treatment.
