Objective: To compare the characteristics of Blaschkoian lichen planus with typical lichen planus. Patients and methods In this case series, we diagnosed 7 patients of Blaschkoian lichen planus (3 males and 4 females) based on specific clinical presentation, histopathological findings and exclusion of other dermatologic disease mimicking Blaschkoian lichen planus. Results Of 7 patients, 4 (57.1...

To the Editor: Graft-versus-host disease (GVHD) is a common and serious complication seen most often with bone marrow transplantation and peripheral blood stem cell transplantation. With these therapies, functional lymphoid cells are transferred from an immunocompetent donor into a nongenetically identical recipient, or “host.” Because of the allogeneic nature of these transplants, the transpla...

In their studies of the oxidation of adrenalin and other amines by amine oxidase preparations, Blaschko, Richter, and Schlossmann (1) found that l-ephedrine, triethylamine, triisoamylamine, and dl-1-hydroxy-2-hydrindeneamine are not only not oxidized, but inhibit the action of the enzyme upon isoamylamine. The conclusion was drawn that this inhibition was of the competitive type, because some d...

Lichens striatus (LS) is an acquired, self-limiting inflammatory dermatosis that follows the lines of Blaschko. The etiology of the eruption is unknown, but several theories have been proposed with focus on environmental factors, viral infection, cutaneous injury, hypersensitivity, and genetic predisposition. We describe a 19-year-old woman who developed a unilateral linear eruption 17 months a...

Sir, Incontinentia pigmenti (IP) is an X-linked dominant trait that is intrauterine lethal for males. The disorder is caused by NEMO mutations involving the NFkB activation pathway (1). It is characterized by linear skin lesions and various defects of the central nervous system, the teeth and the eyes. The cutaneous lesions are arranged along the lines of Blaschko, reflecting functional X-chrom...

Although Keilin and Hartree (1934) and Blaschko (1935) have shown that sodium azide inhibits catalase derived from animal tissue, there is no information about its action on bacterial catalase. It seemed therefore desirable to make a quantitative study of the effects of sodium azide on catalase derived from this source. Since peroxides are metabolic products of many organisms, the inhibition of...

A patient is reported with mental retardation, facial and body asymmetry, and hyperpigmented areas limited to the right side of the body. Cytogenetic studies revealed trisomy 18 in 50% of peripheral blood lymphocytes; fibroblast cultures from the hyperpigmented area showed pure trisomy 18, while the karyotype on the unaffected side was normal. This could be an example of the 'lines of Blaschko'...
