We have previously shown that frontoparietal scleroderma en coup de sabre, a type of linear scleroderma that affects the face and scalp, follows the lines of Blaschko, but the question whether linear scleroderma that occurs in the limbs follows Blaschko's lines has not been answered. We describe the case of a 4-year-old girl with multiple morphea showing remarkable unilateral systematized distr...

Linear psoriasis is a rare entity which is commonly confused with inflammatory linear verrucous epidermal nevus. We report a 25-year-old man who had linear psoriasis along Blaschko lines in a unilateral distribution on the left side of the body. Our diagnosis was based on a combination of historical, clinical, histopathological evidence and response to treatment.

The k-support norm has been recently introduced to perform correlated sparsity regularization [1]. Although Argyriou et al. only reported experiments using squared loss, here we apply it to several other commonly used settings resulting in novel machine learning algorithms with interesting and familiar limit cases. Source code for the algorithms described here is available from https://github.c...

We describe a 10-year-old Japanese girl presenting linear alopecia on the scalp and forehead. Histological examination showed fat degeneration with mucin deposit and periappendageal infiltrate of mononuclear cells. We diagnosed her as having linear lupus erythematodes profundus with a linear configuration following the lines of Blaschko.

Incontinentia pigmenti is a multisystem genodermatosis characterized by cutaneous, neurologic, ophthalmologic, and dental abnormalities. The skin lesions associated with the disease progress through 4 stages, the first being erythematous vesicles linearly distributed along the lines of Blaschko. We report a case of an infant who had incontinentia pigmenti and presented with 2 crops of vesicles ...

Dear Editor, Becker nevus (BN) is characterized by a unilateral lesion consisting of hypermelanosis and hypertrichosis. It develops on the upper torso, shoulders, or arms, especially of male adolescents. Most cases are acquired, and the time of onset varies from infancy to adulthood. Although the etiology of this nevus is not yet known, an association with the expression of androgen receptors i...
