Rare Vascular Birthmark Case Reported in Adolescent Female
A recent medical case has highlighted the presentation of unilateral nevoid telangiectasia, a distinctive and infrequently observed skin condition, in a female adolescent. The occurence offers valuable insights into the identification and understanding of this particular vascular anomaly.
understanding Unilateral Nevoid Telangiectasia
Unilateral nevoid telangiectasia,often manifesting at birth or shortly thereafter,is characterized by a reddish discoloration of the skin. This discoloration is the result of enlarged, or dilated, small blood vessels located close to the skin’s surface. The term “unilateral” denotes that this condition typically affects only one side of the body.
Typically, the blotch appears as a flat, pink to red patch. While largely benign, the condition can sometimes cause emotional distress due to its cosmetic impact. It is crucial to differentiate this condition from other vascular anomalies, as proper diagnosis guides appropriate management and reassurance.
Did You Know? Approximately 1 in 1000 births are affected by some type of vascular birthmark, though, unilateral nevoid telangiectasia is a considerably rarer subset of these.
Details of the Reported Case
The documented case involved a young female adolescent who presented with a noticeable reddish patch on one side of her face. Careful examination revealed the distinct characteristics of unilateral nevoid telangiectasia. Doctors confirmed the diagnosis through clinical assessment and ruled out other potential causes.
The case report underscores the importance of careful dermatological evaluation when encountering unusual skin markings. Early and accurate diagnosis helps in providing appropriate counseling and addressing any psychological concerns the patient or their family may have.
| Characteristic | Description |
|---|---|
| Appearance | Flat, pink to red patch |
| Location | Typically one side of the body |
| Cause | Dilated small blood vessels |
| Severity | Generally benign, primarily a cosmetic concern |
Advancements in Vascular Anomaly Research
Recent years have seen significant advancements in understanding the genetic and molecular basis of vascular anomalies. According to the Vascular Birthmarks Foundation, research is ongoing to identify specific gene mutations associated with various types of vascular malformations. Vascular Birthmarks Foundation
Pro Tip: if you notice any unusual changes in skin markings or the advancement of a new skin patch, consult a dermatologist promptly.
The Importance of Early Diagnosis
Although unilateral nevoid telangiectasia is usually harmless, early diagnosis is essential to alleviate anxieties and provide patients and families with a clear understanding of the condition. It also helps exclude other, potentially more serious, vascular conditions.
Long-Term Outlook and Management
The prognosis for individuals with unilateral nevoid telangiectasia is generally good.The condition typically remains stable over time,although some individuals may experience slight changes in color intensity. While treatment is not usually medically necessary, cosmetic procedures like laser therapy can be considered to reduce the redness if desired. However, these procedures are not always effective and carry potential risks.
Frequently Asked questions About Unilateral Nevoid Telangiectasia
-
What is unilateral nevoid telangiectasia?
It’s a rare skin condition that causes a reddish patch on one side of the body due to dilated blood vessels.
-
Is unilateral nevoid telangiectasia dangerous?
It is indeed generally a benign condition and not life-threatening, but it can cause cosmetic concerns.
-
what causes unilateral nevoid telangiectasia?
The exact cause is unknown, but it’s believed to be related to early developmental issues in blood vessel formation.

Case Report: Unilateral Nevus Flammeus in Adolescent Female: Clinical Presentation and Management
Understanding Nevus Flammeus & Port-Wine Stains
Nevus flammeus,commonly known as a port-wine stain (PWS),is a congenital vascular malformation characterized by dilated capillaries in the skin. These birthmarks are present at birth and typically progress in color and thickness over time. While they can occur anywhere on the body,the face is the most frequently affected area. Unilateral presentation, meaning affecting only one side of the body, is a common pattern. This case report details the clinical presentation and management of a unilateral nevus flammeus in an adolescent female. Key terms related to this condition include capillary malformation, vascular birthmark, and port-wine stain treatment.
Patient Presentation
A 15-year-old female presented to the dermatology clinic with a long-standing, progressively darkening lesion on the left cheek. The patient reported the lesion was noticeable at birth, initially appearing as a faint pink patch. Over the years,it had deepened to a dark reddish-purple hue and exhibited some textural changes,becoming slightly raised in certain areas. She expressed concern about the cosmetic impact of the lesion and inquired about potential treatment options.Her medical history was unremarkable,with no family history of similar vascular anomalies.
Key Findings on Examination:
Location: Left cheek, extending from the zygomatic arch to the mid-cheek.
Size: Approximately 8cm x 6cm.
Color: Deep reddish-purple, with variations in intensity.
Texture: Generally smooth, with subtle nodularity in areas.
Border: Well-defined, irregular.
Palpation: Soft,non-pulsatile. No associated pain or tenderness.
Diagnostic Evaluation
Diagnosis of nevus flammeus is typically clinical, based on the characteristic appearance of the lesion. However, to rule out other vascular anomalies and confirm the diagnosis, the following were considered:
- Dermoscopy: Revealed a homogenous pattern of dilated capillaries.
- Wood’s Lamp Examination: Showed no fluorescence, helping to differentiate it from other skin conditions.
- Histopathology (Biopsy – considered but deferred): While not always necessary for diagnosis, a biopsy can be performed to exclude other vascular lesions, particularly if the clinical presentation is atypical. In this case, the classic appearance made a biopsy unnecessary.
- Ruling out Klippel-Trenaunay Syndrome: Assessment for associated lymphatic or venous malformations was performed, and none were identified, excluding Klippel-Trenaunay Syndrome.
Management strategies for Port-Wine Stains
The management of nevus flammeus has significantly advanced with the advent of pulsed dye laser (PDL) therapy. Historically, treatment options were limited and often ineffective. Current approaches focus on minimizing the cosmetic impact and preventing potential complications.
Pulsed Dye Laser (PDL) Therapy: This is the gold standard treatment for PWS. The laser targets the hemoglobin in the blood vessels, causing them to coagulate and eventually be reabsorbed by the body. Multiple sessions are typically required for optimal results.
Q-Switched Nd:YAG Laser: Can be used as an adjunct to PDL, particularly for deeper or more resistant lesions.
Topical Medications: While not curative, topical medications like timolol maleate have shown some promise in reducing the size and color intensity of PWS, particularly in younger patients.
Cosmetic Camouflage: For patients who are not candidates for laser therapy or are awaiting treatment, cosmetic camouflage with specialized makeup can definitely help to minimize the appearance of the lesion.
Treatment Course & Outcomes
The patient was initiated on a series of PDL treatments using a 595nm pulsed dye laser. A test spot was performed initially to assess the patient’s response and optimize laser parameters.treatments were spaced 4-6 weeks apart.
Treatment Protocol:
Laser: 595nm Pulsed Dye Laser
Fluence: 8-12 J/cm²
Pulse duration: 10-40 ms
Cooling: Dynamic cooling device used to protect the epidermis.
After six treatment sessions, a significant reduction in the size and intensity of the PWS was observed. The lesion’s color had faded from a deep reddish-purple to a lighter pink hue,and the textural changes had improved. The patient reported increased self-confidence and satisfaction with the treatment results. Maintainance treatments are planned every 6-12 months to prevent recurrence. Laser therapy side effects such as bruising and swelling were minimal and resolved within a few days.
Potential Complications of Untreated Nevus Flammeus
While often benign, untreated nevus flammeus can lead to several complications, particularly with larger lesions:
nodularity & Thickening: The lesion can become raised and thickened over time.
Ulceration: The skin overlying the PWS can become fragile and prone to ulceration.
