Angioma em tufos: relato de um caso tratado com laser corante pulsado

Effectiveness of Pulsed Dye Laser Treatment in Tufted Angioma: A Promising Intervention

Introduction

Tufted angioma (TA) is a rare benign vascular tumor usually occurring in the first year of life. It may present as reddish papules or purplish red to black plaques. Tender lesions commonly affect the neck, upper trunk, and shoulders. Histologic tufts of capillaries infiltrating the dermis in a "cannon ball" distribution pattern confirm the diagnosis. However, effective treatments for TA are scarce. Pulsed dye laser (PDL) is an alternative therapy for TA, particularly concerning cosmetics and pain relief. This case report demonstrates the effectiveness of PDL as a treatment for TA.

Case

We report a 15-year-old girl with five-year history of painful purplish red plaques on her left cheek, neck, chest, left shoulder, and back. Histopathological examination from skin biopsy showed discrete "cannon ball" pattern in the dermis. Laboratory examination revealed normal platelet count and fibrinogen level. Based on these presentations, the diagnosis of TA without complications was made. We treated the lesion using 595-nm PDL with 6.5-10 J/cm2 fluence of, 1.5 ms pulsed duration, and 5-7 mm spot size every three weeks. Reductions in redness and pain were seen after four sessions of treatment.

Discussion

PDL promotes selective vascular damage with minimal injury to the surrounding skin. Capillary tufts in TA could therefore serve as a target for laser treatment, which may result in fading redness and pain reduction.

Conclusion

PDL is effective in reducing redness and pain in TA.

Angioma em tufo e síndrome dolorosa miofascial

O Angioma em tufo é considerado um raro tumor vascular cutâneo adquirido. Caracteriza-se por máculas purpúrico-violáceas, dolorosas que podem evoluir para placas com pápulas angiomatosas. Tem natureza benigna, mas o envolvimento extenso é comum, gerando alteração funcional do membro afetado em caso de dor. Os autores relatam um caso de angioma em tufo associado à síndrome dolorosa miofascial, em que o elemento predisponente foi a presença deste tumor desde a infância. A dor local prejudicou a utilização da musculatura e possibilitou o surgimento da síndrome relatada. A realização de bloqueio anestésico de pontos-gatilhos no membro afetado, levou à melhora total dos sintomas.
