Ultrastructural observations in port wine stains
Archives of Dermatological Research, 1988The cause for the progressive vascular dilatation in port wine stains remains unclear. We compared the histology and ultrastructure of lesional and adjacent normal skin in paired biopsy specimens of 12 and 8 patients, respectively (age range, 6 to 53 years).

Port-wine stains: A new hypothesis
Journal of the American Academy of Dermatology, 1987Port-wine stains have been shown to be derived from a progressive ectasia of the superficial vascular plexus. Recent studies have documented a marked decrease in nerves associated with these abnormal vessels. It is suggested that this nerve loss is primarily of autonomic origin (sympathetic) and the failure to regulate blood flow is the basis for the ...

Inflammatory nuchal-occipital port-wine stains
Journal of the American Academy of Dermatology, 1996A port-wine stain is a congenital vascular anomaly caused by a malformation of the papillary dermal capillaries. We observed three children with an unusual appearance of their port-wine stains. All had a prominent inflammatory component consisting of scaling, excoriations, oozing, and crusting, resembling a dermatitis.

Dye laser treatment of port-wine stains
Aesthetic Plastic Surgery, 1990The author treated 456 cases of port-wine stains using a tunable dye laser (577-nm wavelength, 1-microsecond pulse, 2-3-mm diameter spot), and followed up 22 cases for a year or more after the initial treatment. The treatment was regarded as effective in 80.5% of the abnormal lesions.

Our present histological knowledge of the port-wine stain is limited because of the small size of biopsies taken in the past. During the last two decades, Clodius has performed subtotal excision of port-wine stains, and has covered the defects with full thickness skin grafts.

Early Morphea Mimicking Acquired Port‐Wine Stain
Pediatric Dermatology, 2013AbstractWe report the case of a 2.5‐year‐old girl with linear morphea initially diagnosed as an acquired port‐wine stain (PWS). She underwent three treatments to the right face using the pulsed dye laser (PDL) before sclerotic changes were observed and the correct diagnosis was confirmed with histopathology.

Vascular anomalies can be classified as tumors (characterized by proliferating endothelium) and malformations (normal endothelial turnover). Port-wine stain (PWS) is the most common vascular malformation of the skin, present in 0.3–0.5% of newborns. Seventy to 80% of PWS occur in the face and neck regions, initially appearing as flat, pink-red macules ...

Erysipelas on port-wine stain.
European Journal of Pediatric Dermatology, 2017In the literature erysipelas has been not associated with port-wine stain, except for a case we described (1). Erysipelas is an acute superficial cellulitis, caused by group A beta-hemolytic Streptococcus; it can be also observed in the normal child.
