Immunocompromised Districts of Skin: A Case Series and a Literature Review

BACKGROUND

The concept of immunocompromised districts of skin has been developed by Ruocco and helps to explain certain aspects of the macromorphology of skin diseases. This concept unites the isomorphic response of Koebner and the isotopic response of Wolf.

CASE REPORTS

We present different cutaneous conditions which can lead to immunocompromised districts of skin such as scars, radiodermatitis, lymphedema, disturbed innervation or mechanical friction etc. Typical and rarer skin disorders associated with them are discussed and illustrated by their observations.

CONCLUSION

At this moment, we wish to inform dermatologists and non-dermatologists about Ruocco's concept and its implications.

Lupus erythematosus: uncommon presentations

Lupus erythematosus is the great imitator of other diseases. There is a broad range of cutaneous symptoms induced by lupus or by its various treatments. This article provides a short overview of uncommon presentations of cutaneous symptoms in the lupus spectrum.

Unilateral Nevoid Telangiectasia Syndrome

We report on a 29-year-old patient with a unilateral nevoid telangiectasia syndrome (UNTS). Based on microcirculation examinations, both functional impairments at the blood vessel level (laser-Doppler flowmetry) and morphologically altered capillaries (capillary microscopy) could be observed. We could demonstrate that microcirculatory examinations are suitable to demonstrate pathophysiological defects at the vascular level, especially since subclinical functional defects can also be recorded. To our knowledge, no such observations have yet been published with regards to UNTS.
