Photography has been accepted for decades as a standard means for documenting dermatologic conditions and as an adjunct to their treatment, in both medical practice and research. The emergence of low-cost easy-to-use digital imaging systems has made good-quality photography more accessible to practitioners, while providing improved functionality in the clinical environment. Primary concerns are controlling lighting and positioning to provide a clear record of the patients skin condition and maintaining consistency over time to assure meaningful comparison of clinical end points.

The recent advent of digital imaging systems for acquiring and archiving whole body skin images has resulted in greater dissemination of this technique. This in turn has led to the recent establishment of a Category III Current Procedural Terminology code for WBP.

Nevus sebaceus (NS) of Jadassohn is usually a verrucous plaque on the scalp or face that arises secondary to disordered development of epithelial, pilar, sebaceous, and apocrine structures. The emergence of neoplasia is a late stage in the natural history of NS. Although most neoplastic proliferations are benign, several malignant tumors have arisen in this lesion.

Because we have observed marked defects in interleukin-12 (IL-12) production in CTCL and because IL-12 is critical for antitumor cytotoxic T-cell responses, we initiated a phase I dose escalation trial with recombinant human IL-12 (rhIL-12) where patients received either 50, 100, or 300 ng/kg rhIL-12 twice weekly subcutaneously or intralesionally for up to 24 weeks. Ten patients were entered: 5 with extensive plaque, 3 with Sezary syndrome, and 2 with extensive tumors with large cell transformation.

Heparin administered during PCI is known to nonuniformly suppress thrombin activity in the coronary. Persistent elevations of FPA in coronary sinus (CS) blood during PCI have been associated with subsequent ischemic events.
