Introduction:
The closure of scalp defects requires various procedures, but unfortunately with a high rate of sequels.
Observation:
The authors report their experience regarding a large pilomatrixoma of the scalp. The closure of an 8 by 10 cm defect resulting from excision was achieved using a simple tissular extension device during 20 days. The scar aspect was very satisfactory. The device is derived from Cohn's model. It is made of simple and widely used material (vascular lacks, staples).
Discussion:
This simplicity and efficiency of tissular extension devices has been proved. Nevertheless, their use may be restricted. This limitation often results from a high cost and difficulty in applying the adequate tension to the wound edges. Excessive tension may lead to cutaneous necrosis. The use of a simple device derived from Cohn's model seems interesting considering its efficiency, reliability, and low cost.
