Eight cases of the acanthosis nigricans form of epidermal nevus have been described in literature. The present case is impressive and has an extensive segmental distribution. Although etiological factors, such as mutations in the FGFR3 gene, are becoming recognized, treatment options remain limited. We present a case of a 14-year-old male with multiple hyperpigmented, hyperkeratotic plaques on ...

Oculoectodermal syndrome is a rare disease characterized by the association of aplasia cutis congenita, epibulbar dermoids, and other abnormalities. This report describes the twentieth case of the disease. We report a 4-year-old female child who presented with the classical features of the syndrome: aplasia cutis congenita and epibulbar dermoids. Our case expands the clinical spectrum of the di...

Incontinentia pigmenti (IP) is a rare genodermatosis transmitted as an X-linked dominant trait, occurring in 1:50,000 newborns.(1-3) It is frequently lethal in males.(1-3) In this disease, basal cells in the epidermis lose melanin that is collected in the dermis.(2,3) Typically, skin manifestations progress through four stages: vesicular (evident at birth or within the first few postnatal weeks...

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...
