“…Two previously described children had lesions oriented along Blaschko lines (2,3). Given the usual orientation and failure to resolve of their lesions, these patients may have had an alternate diagnosis, such as pigment mosaicism or a variant of incontinentia pigmenti.…”

“…The diagnosis of EDP is based on the appearance of the symmetric, 0.5-2 cm, ashy gray to blue, hyperpigmented oval plaques and patches. Linear lesions that resembled EDP, but were oriented along Blaschko lines, have been described in two prepubertal patients (2,3). Although the presence of erythema at lesional borders is inconsistent, dermal lymphohistiocytic infiltrates are regularly seen in biopsy sections of the hyperpigmented lesions of EDP, with both CD4 + and CD8 + cells demonstrated by immunoperoxidase staining (33).…”

Erythema dyschromicum perstans (EDP) is a rare disorder of pigmentation that is most common in Hispanic patients. In adults, EDP has a slow onset and is unlikely to resolve spontaneously. The etiology and clinical course in children is poorly defined. Physical examinations, chart reviews, and telephone interviews were performed for eight pediatric patients with EDP who were followed at Children's Memorial Hospital in Chicago between 1990 and 1998. All the patients available for long-term follow-up (five of the eight) experienced complete clearance without recurrence in an average of 2.5 years. In all of our patients, the onset was noted from July to December. The administration of aminopenicillins was coincident with the development of EDP in two of the patients. Review of the English-language literature reveals that 25 prepubertal children have previously been reported. Including our patients, 69% of prepubertal children with EDP experienced resolution. We concluded that the clinical course of childhood (prepubertal) EDP differs from that of adult EDP, and it is more likely to resolve within 2-3 years.

“…They are disseminated and symmetrical, located on the trunk and proximal limbs, and may ex tend to the neck and the face (9,32). In three cases, they had a segmentary distribu tion (9,50); one was comprised of linear le sions on the arm (41). The palms, soles, scalp and mucous membranes are spared.…”

“…The palms, soles, scalp and mucous membranes are spared. Once developed, the dermatosis is stable but may disappear spontaneously (38,50) or subside within two to three years (27,51,58). Distinctly different clinical forms have been described on the basis of varying hues or particular location of skin lesion.…”

Erythema dyschromicum perstans (EDP), described by Convit et al. in 1961, is a rare dermatosis. Its relationship with ashy dermatosis (AD), described by Ramirez in 1957, is still a matter of debate. We report a typical case of EDP. The patient, of North African origin, had a dyschromic (hypo- and hyperpigmented) eruption on the chest and limbs for 2 years. The lesions were occasionally surrounded by a papular border which spread slowly and centrifugally. Histological examination showed a lichenoid infiltrate. A carcinoma of the lung was simultaneously discovered. No treatment was given, EDP is infrequent and often considered identical to ashy dermatosis in the literature. However, the clinical aspects of the two diseases differ. The main features of these two diseases are reviewed and compared on the basis of a literature review. We conclude that EDP and AD are distinct clinical entities.

“…The pathogenesis of pediatric EDP is still obscure, although some cases may be associated with drug intake and viral infection (1,3). Two pediatric cases had lesions following Blaschko’s lines, suggesting the involvement of genetic factors (4,5).…”

Erythema dyschromicum perstans (EDP) is asymptomatic slate-gray to blue-brown macules. Idiopathic eruptive macular pigmentation is asymptomatic brown nonconfluent macules. We describe electron microscopic studies of a 9-year-old Japanese girl with EDP. The ultrastructural figures indicated that the production of immature, small, irregular-shaped melanosomes in melanocytes and peripheral localization of melanosomes in keratinocytes caused the clinical appearance of EDP. The ultrastructural evidence distinguishes EDP from idiopathic eruptive macular pigmentation and suggests a distinct pathogenesis of the disease.
