This report provides pictorial evidence that high-resolution gray scale sonography with a PD technique is a real-time and noninvasive imaging technique that can be used as an adjunct to the clinical evaluation in assessing psoriatic disease.

Background: Videocapillaroscopy (VCP) is a method to study the morphology and dynamics of microcirculation, but information about capillaroscopic features of the psoriatic plaque is limited. Objective: To investigate the distribution, morphology and density of capillaries in lesional and perilesional skin of the psoriatic plaque. Methods: VCP of a well-delimited plaque of the trunk, arms or legs in 15 consecutive patients with untreated, chronic plaque psoriasis was performed. Results: In the lesional skin, capillaries were tortuous and dilated, homogeneously appearing as ‘bushy’. In the perilesional skin, capillary loops seemed to be on a parallel course with respect to the skin surface, with their apex directed towards the marginal zone. The number of capillary loops per area unit was statistically increased in perilesional compared to lesional skin. Conclusion: According to the morphology, distribution and density of capillary loops, two different angiogenetic patterns were found in lesional and perilesional skin.

Ultrasound is a rapidly evolving technique that is gaining an increasing success in the assessment of psoriatic arthritis. Most of the studies have been aimed at investigating its ability in the assessment of joints, tendons, and entheses in psoriatic arthritis patients. Less attention has been paid to demonstrate the potential of ultrasound in the evaluation of skin and nail. The aim of this pictorial essay was to show the main high-frequency grayscale and power Doppler ultrasound findings in patients with psoriatic arthritis at joint, tendon, enthesis, skin, and nail level.
