Clinical Image:

Congenital Cutaneous Aplasia of the vertex is well known. However, there are other rarer forms. We present a case of a cutaneous aplasia of the 2 lower limbs. A female infant had a skin defect of the thighs and knees at birth. The cutaneous involvement was deep and wide with exposure of the fascia (10 × 15 cm). The mother had no significant antecedent. The clinical examination was normal and a report for another malformation was negative (transfontanellar ultrasound, medullary, abdominal, radiograph of the spine). Local treatment was performed until an artificial dermis graft could be done (Figures 1 and 2). Aplasia cutis Congenita (ACC) is an uncommon disorder presented at birth [1], which commonly involves the skin of the scalpand other areas, but may involve the subcutaneous tissue, bone, and duramater [2]. Friedan has classified 9 congenital cutaneous aplasia according to its location, its physiopathology, its association with other syndromes. The reported incidence of aplasia congenita varies from one in 10,000 live births to 2.8 in 10,000 newborns, with a pre-disposition for female patients [3]. The etiology of the ACC remains uncertain, but the most likely hypotheses are an anormaly either of closure of the neural tube or of the prenatal vascular development [4]. Several factors have been suspected as possible causes eg, placental infarcts, genetics, teratogenic substances, intrauterine infections and trauma, ectodermal dysplasia, imperfect neural tube closure, and maternal intrapartum drug use and it will most commonly presents as a solitary lesion, located predominately in in the midline vertex. The lesion is non-inflammatory, well dermarcated, and varying in size. The defects can rarely present as ulcers, which appear stamped out and have rotund stellate or elongated forms [3]. 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 abscence of the epidermal appendages remains a characteristic feature [2]. The management remains controversial. The lesion’s location size and depth must be considered. Small localized lesions may be managed conservatively, while bigger widespread lesions may necessitate surgery. In our case, a granulation tissue is present at 7 with decrease in wound size. Nevertheless, a surgical treatment is undertaken because of the articular functional risk; with a good aesthetic and functional result. The latest review of the literature published in 2012 by Tempark et al. lists 45 cases of type V skin aplasia, including 18 knee injuries. The majority is treated by directed healing.
