Dermatopathia pigmentosa reticularis (DPR) is a rare disorder with characteristic triad of generalized reticulate hyperpigmentation, noncicatricial alopecia and onychodystrophy. We report the first case from Syria with classical features of the triad along with hyperhidrosis and adermatoglyphia. Based on previous studies this case is distinguished by the location of alopecia on the beard which is not reported before and distinctive histopathological features were found on the biopsy.

Naegeli(-Franceschetti-Jadassohn) syndrome and Dermatopathia Pigmentosa Reticularis are allelic disorders, both characterized by a congenital generalized reticulate hyperpigmentation, palmoplantar hyperkeratosis and other ectodermal symptoms. The disorders differ in their primary pigmentation localization and hair and dental manifestations. They resemble Dyskeratosis Congenita and Poikiloderma Clericuzio type in many of the skin changes, but especially the presence of leukoplakia and bone marrow disfunctioning in the first, and of telangiectasias, generalized hyperkeratosis of palms and soles, and nail pachyonychia in the latter are distinguishing features.

Dermatopathia pigmentosa reticularis is a rare inherited pigmentary disorder of the skin characterized by generalized reticulate hyperpigmentation, nonscarring alopecia and onychodystrophy. The reticulate pigmentation occurs at birth or during early childhood. We hereby report a 12-year-old Indian patient with this disorder. Read More

Naegeli-Franceschetti-Jadassohn syndrome (NFJS) and dermatopathia pigmentosa reticularis (DPR) are two closely related autosomal dominant ectodermal dysplasia syndromes that clinically share complete absence of dermatoglyphics (fingerprint lines), a reticulate pattern of skin hyperpigmentation, thickening of the palms and soles (palmoplantar keratoderma), abnormal sweating, and other subtle developmental anomalies of the teeth, hair, and skin. To decipher the molecular basis of these disorders, we studied one family with DPR and four families with NFJS. We initially reassessed linkage of NFJS/DPR to a previously established locus on 17q11.

Imprinting is the process whereby genetic alleles responsible for a phenotype are derived from one parent only. It is an epigenetic phenomenon resulting from DNA methylation or modification of protruding histones. When imprinted genes are disrupted, syndromes with characteristic patterns of inheritance and multisystem phenotype occur. Read More

Naegeli-Franceschetti-Jadassohn syndrome and dermatopathia pigmentosa reticularis are autosomal dominant ectodermal dysplasias characterized by the absence of dermatoglyphics, reticulate hyper pigmentation of the skin, hypohidrosis, and heat intolerance. Palmoplantar keratoderma, nail dystrophy, and enamel defects are common in Naegeli-Franceschetti-Jadassohn syndrome, whereas diffuse alopecia is only seen in dermatopathia pigmentosa reticularis. We studied a large Swiss family with Naegeli-Franceschetti-Jadassohn syndrome originally described by Naegeli in 1927 and assessed linkage to chromosome 17q, which was proposed to harbor the Naegeli-Franceschetti-Jadassohn syndrome gene.

Background: Mucinoses of the skin are a group of disorders sharing accumulation of mucin in the skin or hair follicles. Postinflammatory hyperpigmentation, with pigmentary incontinence, is due to loss of melanin from epidermal basal cells and its accumulation in dermal macrophages.

Methods: We describe clinicopathologic features of two patients presenting with the association of pigmentary incontinence with an unusual diffuse, band-like dermal deposition of mucin, clinically presenting with reticular pigmented macular lesions. Read More

Reticulate pigmentation of the neck is a common finding in numerous genodermatoses and acquired diseases. As the neck is readily accessible to medical inspection, it may serve as a diagnostic window for various dermatoses. Several entities out of the spectrum of ectodermal dysplasia present with reticulate or mottled pigmentation on the upper trunk and neck. Read More

Dermatopathia pigmentosa reticularis (DPR) is a very rare disorder with the diagnostic triad of generalized reticulate hyperpigmentation, noncicatricial alopecia, and onychodystrophy. Many other dermatologic findings have been associated with this triad, including adermatoglyphia, hypohidrosis or hyperhidrosis, palmoplantar hyperkeratosis, and nonscarring blisters on the dorsa of the hands and feet. The mode of inheritance is unclear but may be autosomally dominant. Read More

Disorders that are characterized by a reticulate pattern of pigmentation are reviewed. Dyskeratosis congenita (DKC) is the prototype of these. In addition to reticulate hyperpigmentation, mucosal leukoplakia, bone marrow dysfunction, cytogenetic instability, and a predisposition to malignancy are characteristic of DKC. Read More

Dermatopathia pigmentosa reticularis is a rare heritable disorder consisting of a triad of cutaneous findings including reticulate hyperpigmentation, noncicatricial alopecia, and onychodystrophy. In addition to this triad, other variable features of dermatopathia pigmentosa reticularis have been described, including adermatoglyphia, hypohidrosis or hyperhidrosis, and palmoplantar hyperkeratosis. Only 10 cases have been described in the world literature to date, and no clear inheritance pattern has been demonstrated. Read More

Dermatopathia pigmentosa reticularis is a rare disorder that presents as reticulate pigmentation distributed widely all over the cutaneous surface. Only nine patients with this disease have been described previously. Our patient had no fingernail and toenail prints, a striking finding also noted in some, but not all, of the other nine patients.

A classification of primary hyperpigmentation conditions is presented. The emphasis is on clinical aspects and an attempt has been made to show, when possible, a spectrum beginning with localized involvement and progressing to the more extensive involvement. Most primary hyperpigmentation conditions and syndromes are inherited by autosomal dominant genetics; notable exceptions include incontinentia pigmenti, classic dyskeratosis congenita, and xeroderma pigmentosum.

A 14-year-old boy with congenital poikiloderma had anhidrosis, palmoplantar-pitted keratoderma, traumatic bulla formation, and defective dentition, but no abnormalities of the hair, nails, or eyes. This patient was similar in some respects to others reported as having dermatopathia pigmentosa reticularis, the Franceschetti-Jadassohn syndrome, the Mendes da Costa syndrome, and acrokeratotic poikiloderma.
