“…In the field of dermatology, it is known that many naevoid skin lesions and dermatoses display an arrangement following the Blaschko lines 12 . On the occipital scalp, the transverse line of the present cases may be compatible with the lines of Blaschko, but any explanation for the reason why LE profundus develops along these lines is beyond the scope of this paper.…”

SummaryLichen planus is characterized by lichenoid, polygonal papules with fine white lines, called Wickham striae. Lesions most commonly occur on the limbs and on the dorsal aspect of the trunk. At the same time often leukoplakia of mucous membranes as well as nail disorders are seen.There are numerous variants of lichen planus which can be distinguished from the classical form on the basis of morphology and distribution of the lesions. The typical primary lesion of lichen planus may be replaced by other forms, such as patches, hyperkeratoses, ulcerations, or bullous lesions. Moreover, distribution patterns of these lesions may vary and include erythrodermic, inverse or linear arrangements. In contrast to these numerous clinical features, histologic findings remain characteristic in the variants, so that the diagnosis can be made securely. Differential diagnoses of lichen planus include diverse dermatoses such as bullous pemphigoid or paronychia.

“…This consistent pattern was once described as dermatomal (19) or methameric (20). In reviewing the literature, different classification systems have been described, based on the concept of genomic mosaicism, ie, two genotypically distinct cell lineages within one organism (21)(22)(23)(24), histological appearance, cutaneous distribution (9) and depth of pigmentation (25). These classification systems try to address the issue of potential malignancy and recurrence following excision.…”

Congenital giant nevocellular nevus of the back with deep extension to the fat and fascia

MRO Jaeger, RM Zuker. Congenital giant nevocellular nevus of the back with deep extension to the fat and fascia. Can J Plast Surg 2006;14(1):45-48.The presence of deep pigmentation in a giant congenital nevus makes its complete removal very difficult and should be taken into consideration when planning for treatment. A clinical case in which the pigmented lesion was found to extend deep into the muscle fascia is described. The lesion was surgically removed with an acceptable functional and aesthetic result through the utilization of tissue expansion. The development of new surgical techniques and the expansion of laser technology will possibly provide new treatment options in the future. Emphasis should be placed on aesthetics and function, because the excision based only on oncological anticipation is no longer valid. The presence of deep pigmentation makes certain treatment options less effective than surgical ablation.Key Words: Giant congenital nevi; Laser; Tissue expanders Naevus cellulaire congénital géant dans le dos, avec pénétration profonde dans le tissu adipeux et le fascia La présence d'une pigmentation profonde dans un naevus congénital géant rend son excision complète très difficile, et cet aspect devrait être pris en considération lorsque vient le moment de planifier le traitement. Voici un cas clinique de lésion pigmentée avec pénétration profonde dans le fascia. La lésion a été excisée convenablement des points de vue fonctionnel et esthétique par le recours à des expanseurs tissulaires. La mise au point de nouvelles techniques chirurgicales et le développement de la technologie laser déboucheront peut-être sur l'élaboration d'autres traitements. Une attention particulière devrait être portée aux aspects esthé-tique et fonctionnel, parce qu'aujourd'hui l'excision fondée sur le seul critère de la prévision oncologique ne suffit plus. La présence d'une pigmentation profonde rend certains traitements moins efficaces que l'excision chirurgicale.
