Dermoscopy of Port-Wine Stains

Contrasting Vascular Patterns: A Helpful Dermoscopic Feature for Identifying Basal Cell Carcinoma Within Port Wine Stains

“…In deeper PWSs, red linear vessels, reflective of horizontally orientated vessels, are seen on dermoscopy; 5 this is the pattern observed in our patient (Figure 3). In the more superficial form of PWS, where vertically orientated vessels predominate, rounded, red, globular vessels are observed 5 . The use of dermoscopy in cases where BCC occurs within a PWS may assist with delineation of clinically ill‐defined lesions but is not a substitute for Mohs micrographic surgery where indicated.…”

“…Focal ulceration and varying degrees of pigmentation may also be observed. Dermoscopy has been used to look at PWS, with particular emphasis on determining the depth of the malformation to predict response to therapeutic intervention with laser 5,6 . Vazquez‐Lopez and colleagues have described distinctive superficial papillary and deeper subpapillary vascular patterns 5 .…”

Dermoscopic Appearances in the Superficial and Deep Type of Infantile Hemangioma

“…Here, we focus on the dermoscopic appearances of vasculardominant features of the mixed type infantile hemangioma. Dermoscopy can subdivide a mixed type into polymorphous vascular forms [3], mostly reddish, diffuse reddish, and cerebriform reddish.…”

“…Dermoscopy is useful for immediate and precise diagnosis for infantile hemangioma without proliferation (infantile hemangioma precursor) from capillary malformation of port-wine stain [1][2][3]. Infantile hemangioma is clinically classified as superficial, superficial and deep (mixed), and deep.…”

Dermoscopy: distinguishing malignant tumors from benign

“…They correspond to superficial ectatic vertical papillary vessels and with deeper ectatic horizontal subpapillary capillaries, respectively [139][140][141].…”
