Conservative Healing of an 11 × 9-cm Aplasia Cutis Congenita of the Scalp with Bone Defect

Large aplasia cutis congenita of the vertex conservative management

BACKGROUND

Aplasia cutis congenita (ACC) of the vertex with bone defect is a rare and begnin anomaly that can involve the epidermis, dermis, and subcutaneous tissues of the scalp with significant bone defect Bajpai and Pal (J Pediatr Surg 38(2):e4, 2003). When associated with skull defect, this rare malformation carries the risk of severe complications such as rupture of the superior sagittal sinus or infections.

METHODS AND RESULTS

We report a case of aplasia cutis congenita of the scalp with skull defect measuring 9 × 10 cm and an exposed sagittal sinus in a newborn. Both conservative and surgical methods have been proposed to treat this condition. In our case, conservative treatment was planned led to complete epithelization and the patient was healing well at 5 years of follow-up.

CONCLUSIONS

ACC of the vertex with a large scalp defects present a management dilemma Rocha et al. (Clin Case Rep 3(10):841-4, 2015). Based on a review of the literature, we report this case to demonstrate that even for the largest skin and bone defects, an initial conservative approach may allow for complete wound closure without the need for early surgical intervention.

A novel DLL4 mutation in Adams-Oliver syndrome with absence of the right pulmonary artery in newborn

Adams-Oliver syndrome (AOS), a rare inherited disorder, is characterized by scalp and terminal limb defects. Several genes associated with Notch pathway mutations have led to AOS. Here, we report a Thai male newborn presenting with aplasia cutis congenita and absence of a right pulmonary artery, which is suggestive of AOS. This was confirmed by the identification of a novel missense mutation in DLL4, a heterozygous one base pair change at nucleotide 82 (c.82G>C, p.Gly28Arg), which is in N-terminal domain. This is the first DLL4-related AOS case with arterial defect.

An Aplasia Cutis Congenita: Suggestion of Management Algorithm

BACKGROUND

When a child is born with Aplasia cutis congenita (ACC), it is important for the surgeon to decide promptly whether to perform early surgical intervention, or proceed with conservative care. Several patients of ACC have been reported in which various treatments have attempted. However, the criteria of treatment remain controversial. In this study, the authors present an algorithm and the literature review to assist with objective decisions during ACC management.

METHODS

A total of 4 cases of infants born with ACC were referred to our department between January 2017 and April 2019. Conservative care was to be considered a first choice of management.

RESULTS

The ACC lesions were presented in the scalp vertex area in all 4 infants with the intact dura mater. There was no large vein exposure or sagittal sinus exposure in all infants. All 4 infants were managed with conservative care, which immediately resulted in complete healing of the defects without any complications.

CONCLUSIONS

Rapid decision-making is required whether or not the patient requires emergency surgical coverage. Even extensive defects may be healed by conservative care alone, if the dura mater is intact and accompanying large vein or sagittal sinus exposure is not identified.

Aplasia cutis congenita: Two case reports and discussion of the literature

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.

Treatment of multiple wounds of aplasia cutis congenita on the lower limb: a case report

INTRODUCTION

Aplasia cutis congenita (ACC) is a rare congenital disease, characterised by absence of skin, that can affect different parts of the body. ACC is more frequent on the scalp, but can involve limbs, with partial-or total-thickness loss of skin, with a functional impairment of the joint affected. There is no clear indication for surgical or conservative treatment, therefore, it would be helpful to find scientific support for the optimal treatment strategies.

CLINICAL PRESENTATION

We present a case of a newborn female, with six wounds on the inferior limbs, treated with conservative therapy. To prevent infection and promote healing, the defects were kept moist and covered with non-adherent/antimicrobical dressings. Complete wound healing occurred in eight weeks. The duration of follow-up was three years.

RESULTS

In this kind of ACC with superficial partial-thickness wounds of the lower limbs, conservative treatment was successful. The same conservative treatment can be proposed for larger or deeper wounds of lower limbs with no involvement of underlying structures, with delayed scar excision after the complete growth of the patient. ACC scar excision could require complex tissue rearrangement, tissue expansion, or skin grafting.

CONCLUSION

In the evaluation for treatment of ACC of inferior limbs, even in cases of total-thickness skin loss, even on joints, the conservative approach could be considered as the first choice.

Conservative Treatment of Large Aplasia Cutis Congenita of the Scalp With Bone Defect With Basic Fibroblast Growth Factor Application

The object of this report is to share our experience of conservative management of giant aplasia cutis congenita (ACC) of the scalp with the topical application of basic fibroblast growth factor (bFGF). Complete epithelialization of the 9 × 8 cm sized defect was achieved in 33 weeks. Careful conservative management could eliminate the requirement of surgery for giant ACC defects of the scalp with bone defects and should be tried if surgery is thought to be risky or has consecutive morbidity. Topical bFGF application seems to accelerate healing, also providing a better epithelium for later reconstructive treatments and its usage could be standardized in the future.

Failed conservative management of a case of aplasia cutis congenita in a low-income country

Aplasia cutis congenita is a rare disease characterized by absence of skin layers. Usually the scalp is affected, but the whole body can be involved. We report extensive aplasia of a baby born of a HIV‐positive mother taking antiretroviral drugs. Conservative treatment was not enough to ensure her survival.
