Large defects in aplasia cutis congenita treated by large-sized thin split-thickness skin grafting: long-term follow-up of 18 patients

A practical approach to the evaluation and treatment of an infant with aplasia cutis congenita

Aplasia cutis congenita (ACC) is a term describing absence of skin at birth. ACC is a rare cutaneous finding, often noted with no other physical abnormalities. The etiology of ACC varies, and there are likely several causes for its development. ACC can be located anywhere on the body. Its clinical appearance and location can alert the clinician to other potential abnormalities and associations. This discussion covers the diagnosis of ACC and its subtypes and associations in order to provide a pragmatic, clinically relevant and patient-centered approach to evaluation and treatment.

A Practical Approach to the Diagnosis and Management of Hair Loss in Children and Adolescents

Hair loss or alopecia is a common and distressing clinical complaint in the primary care setting and can arise from heterogeneous etiologies. In the pediatric population, hair loss often presents with patterns that are different from that of their adult counterparts. Given the psychosocial complications that may arise from pediatric alopecia, prompt diagnosis and management is particularly important. Common causes of alopecia in children and adolescents include alopecia areata, tinea capitis, androgenetic alopecia, traction alopecia, trichotillomania, hair cycle disturbances, and congenital alopecia conditions. Diagnostic tools for hair loss in children include a detailed history, physical examination with a focused evaluation of the child’s hair and scalp, fungal screens, hair pull and tug test, and if possible, light microscopy and/or trichoscopy. Management of alopecia requires a holistic approach including psychosocial support because treatments are only available for some hair loss conditions, and even the available treatments are not always effective. This review outlines the clinical presentations, presents a diagnostic algorithm, and discusses management of these various hair loss disorders.

Outcomes of Tissue Expander Application for Scalp Reconstruction in Extensive Aplasia Cutis Congenita

INTRODUCTION

Aplasia cutis congenita (ACC) is a rare congenital disorder. The purpose of this study was to present outcomes of tissue expander application for scalp reconstruction in extensive ACC.

PATIENT/METHODS

In this retrospective study, medical records were reviewed for six patients who underwent serial tissue expander application for scalp reconstruction in ACC between 2000 and 2015. Patient average age was 14.5 (range, 4-25 years). One of the six cases had frontal bone defect, the others had bone and soft tissue defect at the vertex. In the newborn period, all patients have been managed by split-thickness skin grafts without cranioplasty procedures. After grafting and calvarial regeneration, one (or more) sessions of tissue expanders and scalp flap applications were performed for alopecia and soft tissue correction. Radiologic and clinical examination was performed for complications and outcomes.

RESULTS

Computerized tomography showed intact calvarium with patchy hyperostosis in all patients. The mean size of grafted areas was 69.5 cm(2) (range, 32-148.5 cm(2)). Minimal distal flap necrosis (6 × 1 cm) was observed in one patient. Serial scalp tissue expansion was performed with at least one session in a 1-year interval. One expander was extracted due to exposition and infection. No total flap losses and no calvarial defects were observed during follow-up (mean; 8.6 years). Clinical examination revealed acceptable cosmetic results in all patients.

CONCLUSION

We advocate late expander scalp reconstruction for management of extensive ACC cases.
