Ossifying Panniculitis Presenting as a Painful Nodule on the Abdomen.

Myositis ossificans is a benign ossifying nodule that can affect any type of tissue but is most commonly found in muscle. Occurrence in the soft tissue of the subcutis is less common and has been referred to as panniculitis ossificans. In this case report, we describe a 46-year-old woman who presented with a 1.

Cutaneous ganglioneuroma: A case report and discussion of the literature.

Ganglioneuromas (GNs) are benign tumors composed of ganglion cells in a Schwannian stroma. They are derived from neural crest cells that give rise to the sympathetic nervous system. Hence, GNs can be found anywhere a sympathetic ganglion is present.

Gianotti-Crosti syndrome after H1N1-influenza vaccine.

Papular acrodermatitis of childhood, or Gianotti-Crosti syndrome, is a symmetric papular or papulovesicular acral exanthem associated with several infectious agents and immunizations. We present a case of Gianotti-Crosti syndrome appearing shortly after H1N1-influenza vaccination. This has not been previously reported to our knowledge.

A switch in Notch gene expression parallels stem cell to endothelial transition in infantile hemangioma.

Background: Infantile hemangioma (IH) is the most common benign tumor of infancy, yet its pathogenesis is poorly understood. Notch family members are known to play a role in vascular development during embryogenesis and postnatal tumor angiogenesis, yet the role of Notch signaling in the pathogenesis of IH has not been investigated. This study aims to survey Notch expression in IH.

Brain structural abnormalities in psychotropic drug-naive pediatric patients with obsessive-compulsive disorder.

Objective: The authors investigated structural abnormalities in brain regions comprising cortical-striatal-thalamic-cortical loops in pediatric patients with obsessive-compulsive disorder (OCD).

Method: Volumes of the caudate nucleus, putamen, and globus pallidus and gray and white matter volumes of the anterior cingulate gyrus and superior frontal gyrus were computed from contiguous 1.5-mm magnetic resonance images from 23 psychotropic drug-naive pediatric patients with OCD (seven male patients and 16 female patients) and 27 healthy volunteers (12 male subjects and 15 female subjects).
