Acquired port-wine stain is rare. It mimics a congenital port-wine stain morphologically but the pattern of onset is acquired after birth. It represents a progressive ectasia of vessels located in the superficial vascular plexus. The exact mechanism is unknown but some reported cases have occurred after trauma. We herein report five cases of acquired port-wine stains and they were idiopathic in nature.

78 patients with Port wine stains (PWS) were treated by surgical method. The result showed that surgery is useful and effective. However, surgical scars are common and the skin grafts have more dark color than surrounding (if the skin grafts were required). So it must be very carefully in making a decision for surgery and choose a suitable method for each patient. The surgery is attempted to close local skin. And in case of the skin graft is required, it is better to take a full thickness skin graft in areas near to the face and neck.

The study was conducted on 84 patients with Post-wine stain from January 1995 to April 1999 in the Army Central Hospital 108. This genital condition develops laterally on skin of face and neck and in upper and middle areas of face. Lesions were characterized by colour, prominency, lump, Waner grade and ligh-colour changeability when stretching skin. Usually, this condition is more severe in adult patients and if the lesion occurred on upper lip, the condition were more complicated with lip enlargement and involved in mucous membrane.

We observed the histopathological findings in 16 patients with nevus flammeus according to the time sequence after argon laser therapy. The results were as follows : 1. Immediately after treatment There was nonspecific damage to the epidermis, upper part of the dermis and upper portion of the pilosebaceous unit to a depth of 0.4~0.5mm depth. The specific damage to the vessels, which showed thrombi formation and partial disruption of the vessel walls was seen to a depth of 0.8~0.9mm. 2. One week after treatment Crust was formed and the epidermis regenerated almost completely. The thrombi still persisted and there was partial disappearance of the vessel walls. 3. Four to 10 months after treatment The epidermis appeared normal except the rete ridge flattening. The upper dermis was diffusely fibrotic, with relatively few residual vessels, many of them with slit-like contour.

BACKGROUND: Port wine stains (PWSs) are commonly treated with pulsed dye laser (PDL) as a standard therapy. However, it is not easy to predict the minimal effective dose in the first treatment session. OBJECTIVE: The aim of this study was to assess whether dermoscopic findings before and after laser irradiation corresponded with the clinical improvement of PWS in patients undergoing PDL therapy. METHODS: Seven untreated PWSs in 6 patients (a male and 5 females), who presented to our hospital between May 2008 to January 2010, were assessed in this study. The mean age was 36.3 years, ranging from 14 to 57 years. A PDL with a wavelength of 585 nm and a spot size of 7 mm was used. Before and after test irradiation, patients underwent dermoscopy and clinical photography, and we assessed whether the dermoscopic findings corresponded with clinical improvement after 3 months. RESULTS: There were no obvious differences observed in the clinical photographs between each test level immediately after irradiation. However, dermoscopic photographs showed differences as the irradiated energy increased. These changes corresponded to the clinical improvement after 3 months. CONCLUSION: Our study indicates that the minimal effective fluence can be predicted by observing dermoscopic change immediately after irradiation. We think that examining the dermoscopic findings immediately after irradiation allows the laser surgeon to predict the minimal effective fluence and this prevents adverse effects of the skin.

Although port-wine stains present as macular patches generally, some patients show considerable overgrowth of angiomatous tissue and show different results of laser therapy according to their histologic patterns. We observed 337 port-wine stain patients clinically, and tried to classify clinical morphology of port-wine stains and analyze with other features such as color, age and size. The results were as follows: Most of the lesions were located on the face, followed by neck, upper extremity, lower extremity and trunk in order. 2, On the face, the left lower part was the most frequent area of the lesions. The difference of the distribution between right and left side was not found, but the lesions were significantly more frequent on the lower part than the upper one. 3. The morphology was classified into patch, hypertrophic, cavernous and papular form according to therapeutic purpose. 4 When the color is darker, the others than the patch form appeared. 5, In old patients the color was darker and the papular form increased. 6. When the size enlarged, the hypertrophic form. increased. 7. Among ten patients who got the lesions at both the upper and lower eyelids, two showed ocular problems.

BACKGROUND: Recent reports have proposed that there were no differences between acquired port-wine stain (APWS) and congenital port-wine stain (CPWS) except the onset of disease. Pulsed dye laser (PDL) therapy is regarded as the treatment of choice in PWS. Although in some articles, APWS might have shown a better response to PDL than CPWS, this is still controversial. It has been assumed however, that there might be some differences determining therapeutic responses between the two entities. OBJECTIVE: The purpose of this study is to find out some histopathologic differences between APWS and CPWS. METHODS: 14 patients with APWS and 17 patients with CPWS from our patient files were included in this study. Immunohistochemical staining by factor VIII-related antigen was carried out on the specimens of punch biopsy to better visualize the blood vessels. Histopathologic assessment of variables such as vessel area, percentage of vascular area and vessel depth was performed using a computer-assisted image analyzer program. RESULTS: The mean vessel area in APWS was 1014.7 +/- 782.5micrometer2 and that of CPWS was 1341.5 +/- 689.9micrometer2. The mean percentage of vascular area in APWS was 2.02 +/- 1.38% and that of CPWS was 2.65 +/- 1.56%. The mean vessel depth in APWS was 327.5 +/- 120.7micrometer and 321.7 +/- 93.1micrometer in CPWS. No histopathologic variable was statistically significant using the Mann- Whitney test (p>0.05).

Spinal dysraphisms are defined as open and closed dysraphisms. A hemivertebra is a congenital condition seen in 61% of patients with congenital anomalies. The first report of the excision of a hemivertebra was by Royle in 1928. A sixteen-year-old girl was admitted to our clinic with a congenital stain on the waist and a normal neurological examination. No new cases have been reported in recent literature. Our case, which is also rare, is associated with a tethered cord only and no other congenital abnormalities.
