Atypical angioma serpiginosum

Area of Science:

• Dermatology
• Vascular Disorders

Background:

• Angioma serpiginosum is an uncommon, acquired vascular nevoid disorder.
• Characterized by asymptomatic, grouped, erythematous to violaceous, serpiginous and punctate macules in the papillary dermis.
• Typically presents in adolescent females on lower extremities and buttocks.

Observation:

• A rare case of angioma serpiginosum with late onset and atypical distribution is presented.
• The patient was a 48-year-old female with punctate lesions on her left foot for 4-5 years.
• Histopathology revealed hyperkeratosis and dilated, proliferated capillaries in the papillary dermis without inflammation or red blood cell extravasation.

Findings:

• Clinical and pathological findings confirmed a diagnosis of angioma serpiginosum.
• The patient's condition showed improvement after pulsed dye laser treatment.
• This case expands the known clinical spectrum of angioma serpiginosum.

Implications:

• Pulsed dye laser therapy is an effective treatment option for angioma serpiginosum.
• Highlights the importance of considering atypical presentations in diagnosis.
• Contributes to understanding the variable clinical manifestations of this rare vascular disorder.
