Helen Ollendorff Curth (1899-1982), is one of the pioneers in dermatology. In 1954, she and Madge Thurlow Macklin (1893–1962), an American medical geneticist, reported, a rare congenital genodermatosis that was later known as Curth-Macklin syndrome. This syndrome is a rare autosomal dominant skin disorder characterized by extensive hyperkeratosis and palmo-plantar keratoderma. This report shed ...

Progressive symmetrical erythrokeratodermia is a rare autosomal dominant genodermatosis with variable penetrance described by Darier in 1911. It is characterized by erythematous and keratotic plaques, sharply defined and symmetrically distributed along the extremities, buttocks and, more rarely, on the face. We report a case of a 55-year-old patient with lesions on the dorsum of the hands, inte...

Abstract A 35-year-old woman presented with a 4-year history of persistent pruritic rash affecting her upper and lower limbs, concerning to the patient for cosmetic reasons. She denied any precipitating factors reported no improvement use topical clobetasol propionate. Notably, mother had similar rash, which also developed in 30s continued progress over time. Physical examination revealed bilat...

Keratinocyte differentiation, adhesion and motility are directed by extracellular Ca2+ concentration increases, which in turn increase intracellular Ca2+ levels. Normal keratinocytes, in contrast to most non-excitable cells, require Ca2+ release from both Golgi and endoplasmic reticulum Ca2+ stores for efficient Ca2+ signaling. Dysfunction of the Golgi human secretory pathway Ca2+-ATPase hSPCA1...

Background: Incontinentia pigmenti (IP), also known as Bloch-Sulzberger syndrome, is a rare X-linked dominant genodermatosis that presents at the time of birth or soon after birth with cutaneous manifestation. This disorder may also affect the ectodermal tissues, such as the central nervous system, skeletal system, eyes, hair, nails, and teeth. The dermatological findings occur in four successi...

H syndrome is an autosomal recessive genodermatosis with reports dating back to the last decade. This syndrome is caused by mutations in the SCL29A3 gene. The clinical characteristics of this syndrome consist of dermatological manifestations, including hyperpigmented, hypertrichotic, and indurated patches and plaques. It affects various systems by causing heart anomalies, hepatosplenomegaly, hy...

von Recklinghausen disease (vRD), more widely known as neurofibromatosis type 1, belongs to a group of genetic disorders and it is considered to be the most common genodermatosis. The disease has an autosomal dominant pattern of inheritance that involves mutations within the NF1 gene located on chromosome 17 in locus q11.2. The product of the NF1 gene is neurofibromin and the protein is well kn...

Zinsser-Cole-Engmann syndrome, more commonly known as Dyskeratosis Congenita, is a heritable genodermatosis having an estimated incidence of 1 in 1 million people. It is important for an oral physician to be aware of this condition as oral leukoplakia occurs in this condition as part of a classic triad along with reticulate skin pigmentation and nail dystrophy. Besides these, there may be myria...

BACKGROUND Familial progressive hyper- and hypopigmentation (FPHH) is a rare genodermatosis that is characterized by diffuse hyper- and hypopigmented spots on the skin and mucous membranes. It is caused by a pathogenic mutation of the KITLG gene. OBJECTIVES To investigate the clinical features and mutation of the KITLG gene in a Chinese family with FPHH. METHODS Histopathological and immuno...
