[Aplasia cutis congenita of the scalp (5 observations)].
Aplasia cutis congenita (ACC) is an uncommon congenital malformation. It is characterized by defects of the skin that occur most frequently on the scalp along the midline, but can also be localized on the trunk, face and limbs, usually with a symmetrical distribution. When it is localized in the skull, it can extend to the dura mater, with only the thin pia mater to protect the brain.


METHODS
We report a retrospective study during a period of 10 years and we report 5 cases of ACCV hospitalized in the pediatric service in CHU Hédi Chaker and in maxillo-facial surgery service in CHU Habib Bourguiba, Sfax. We studied the epidemiologic, clinical, and therapeutic aspects in our patients.


RESULTS
The average age at the admission was 5 days (2-8 days). A consanguinity was found in 2 cases. The clinical examination revealed cutaneous and osseous structures aplasia located in frontoparietal zone in 3 patients and in parieto-occipital zone in a patient. A hypoplasia of the toes was noted in 3 cases and a hypoplasia of the 3rd finger of the 2 hands in a case. Plain X-ray skull (3 cases) showed the osseous defect in all the cases. The cerebral IRM (2 cases) showed osseous and cutaneous defect in two cases and a lipome of the corpus callosum in one patient. A surgical repair using a cutaneous graft was performed for 3 patients. A patient died on the 16th day of life from a haemorrhage of the longitudinal sinus. The evolution was favourable in 4 cases with a cicatrisation of good quality but with subsequent alopecia.


CONCLUSIONS
ACC of the scalp is a rare and often sporadic affection. Our experience confirms that fatal bleeding from the longitudinal sinus can occur during the 1st weeks of life.
