OBJECTIVE Necrotizing fasciitis is a highly lethal soft tissue infection rarely reported in childhood. The initiating site is usually a local trauma or a surgical wound. We observed five cases of necrotizing fasciitis the initiating site for which was the mammary region and discuss their management. STUDY DESIGN We describe these five patients and review(More)
Mathematical models are being developed at a fast rate in industry thanks to computer technology; they are used to simulate motion and deformation over time to test materials and objects in a virtual manner. These modeling techniques are being developed in medicine, but they remain, at this time, in the domain of biomechanical research. We report a(More)
The rise of the utilization of tissue expanders and procedures like liposuction have brought us a better understanding of the biomechanical properties of the skin as a living organ. This understanding has helped us to appreciate better the etiopathology of a dog ear deformity and to utilize the same properties for its correction by simple methods and thus(More)
Cellular adhesion molecules are newly identified mediators of angiogenesis. Infantile hemangiomas, characterized in the early stages by a proliferation of poorly differentiated vessels followed in the late stages by a vascular differentiation and regression of the tumor, represent an interesting model to study angiogenesis. We studied by(More)
Methods for serial cultivation of human keratinocytes can provide large quantities of epidermal cells, which have the potential of restoring the vital barrier function of the epidermis in extensive skin defects such as burns. To investigate the value of combining an epidermis with a dermal component, fibroblasts originated from the superficial dermis were(More)
BACKGROUND Melanotic neurofibromas are rare tumours. The clinical and histological diagnosis is often difficult to make. CASE REPORT A 41 year-old woman with type-1 neurofibromatosis presented with an old, large (16 cm by 6 cm) pigmented tumour on her left arm. It was initially considered to be a congenital naevus. Partial surgical resection was(More)
Large congenital melanocytic naevi (LCMN) represent the main risk factor for development of melanoma in childhood. This retrospective study of 10 cases of melanoma in patients with LCMN used fluorescence in situ hybridization (FISH) and comparative genomic hybridization (CGH) (6 cases) to elucidate the clinical, histological, and cytogenetic characteristics(More)
This paper presents a new method of reconstruction of a large skin defect, e.g., following excision of a giant pigmented nevus. By taking advantage of the flexibility of the joints and the extensibility of skin in the children, the large defects were closed in one stage by an enforced position that allows an easy closure of the wound. The scar was protected(More)
INTRODUCTION Blue nevi are small acquired melanocytic tumors. Two clinical forms are described, a fibrous form and a cellular form. Giant nevi are exceptional. CASE REPORT We describe a patient with a giant blue nevus of the scalp. In addition to this congenital, noninvasive tumor the patient presented numerous cutaneous melanocytic nevi. The main lesion(More)
Reconstruction after excision of a cutaneous lesion of the face is done by various complex old and new flaps to avoid any distortion. The distortions following primary closure of defects in the face are given undue importance. We have observed and used the capacity of self-correction of these distortions, which is partially due to the muscular actions. We(More)
