Lasers for cutaneous lesions: An update

There are several types of medical settings which use lasers. Dermatologists use lasers as it is non-invasive with preferential cosmetic outcomes and finer wound healing. The types of lasers are relying on their wavelengths and delivery systems. Over time, by using several distinct devices and strategies, new lasers have been generated; as a consequence, they are manipulated in a wide range of dermatological settings. In this review, laser applications in various vascular, infectious, and hyperpigmented cutaneous lesions were framed. We aimed to represent the fitness of phototherapy for each condition as well as the overall challenges that face laser. In addition, low-level laser therapy, and laser resurfacing were noted as the marketable line of lasers in the current time for cosmetic purposes.

Angioma serpiginosum in zosteriform distribution on abdomen: A rare presentation

Angioma serpiginosum is a rare benign nevoid disorder affecting the small vessels of the upper dermis. We are presenting a case of this rare disease in an 11-year-old girl who presented with this condition on abdomen in zosteriform pattern which is rare presentation and is the first of its type.

Angioma serpiginosum: a case report and review of the literature

Background

Angioma serpiginosum is a rare vascular anomaly whose pathogenesis is still unknown. It is characterized by the onset of vascular reddish macules and papules during childhood, lesions are usually monolateral with a linear serpiginous pattern. It is rarely associated with extracutaneous findings. This entity has not yet been included in the classification of the International Society for the Study of Vascular Anomalies.

Case presentation

We describe the first Italian report of angioma serpiginosum with a congenital symmetrical presentation. The patient had a further extension of macules during puberty involving both of the soles. No extracutaneous manifestations were present. Diagnosis was confirmed with dermoscopy and light microscopy that revealed the typical clusters of dilated, thickened and PAS+ capillaries in the upper dermis. Moreover, Immunohistochemistry showed positive WT-1 staining. Genetic analysis with next generation sequencing did not detected any mutation.

Conclusions

Our patient presented a peculiar symmetrical and planar extension with a serpiginous linear pattern. The proliferative nature of this condition has been widely discussed in literature. In our case immunohistochemistry was positive for Wilms tumor-1, a new endothelial marker expressed during angiogenesis in reparative processes and endothelial tumors.

Clinical evolution, histological and immunohistochemical findings suggest that angioma serpiginosum should be considered as a vascular proliferation. For these reasons we think it should be included in the international classification as a tumor.

When not to treat cutaneous vascular lesions with the pulsed dye laser

The availability of effective laser treatment for cutaneous vascular lesions has risen dramatically in recent years. At the same time, there has been a proliferation of laser providers with varying amounts of training-both medical and nonmedical. We report a series of four cases where patients presented for cosmetic evaluation of vascular lesions and were discovered to have more significant pathologic disease. In presenting these cases, we hope to illuminate a basic differential diagnosis that exists for cutaneous vascular lesions and remind healthcare providers that not all "cosmetic" concerns are benign in origin. There is a differential diagnosis that exists for cutaneous vascular lesions that is worth reviewing, and it should be considered in all patients presenting for laser treatment.
