In Part II of this review of pediatric dermoscopy, we will focus on the use of dermoscopy for non-melanocytic tumors, skin infections, and inflammatory rashes. Dermoscopy is a valuable tool in confirming the vascular nature of a growth and can help determine if an infantile hemangioma is at risk of ulceration. In addition, dermoscopy helps evaluate solitary papules when the diagnosis is in question. Sometimes, when our naked eye examination is unable to distinguish between entities, dermoscopy improves diagnostic accuracy to allow for appropriate management. 1 2 | VA SCUL AR AND LYMPHATI C LE S I ON S 2.1 | Infantile hemangiomas and angiokeratomas Infantile hemangiomas are benign vascular tumors that appear within the first few weeks of life. They are marked by an initial proliferative phase, followed by spontaneous involution. 2,6 Dermoscopically, hemangiomas appear as well-demarcated, round-ovoid structures composed of red lacunae, or lakes of blood, separated by white septae. 3 Dermoscopy is useful in helping to subclassify hemangiomas as superficial, deep, or mixed. 3 The lacunae in superficial hemangiomas are bright red in color, whereas those in deeper hemangiomas are marked by a blue or violaceous hue (Figure 1). 2,3 The dermoscopic findings of hemangiomas are the same as in cherry angiomas. Spider angiomas have a central red lobular appearance with arborizing thin red lines, which are easily blanchable with the dermatoscope. 4 Dermoscopy also aids in the management of infantile hemangiomas. The white color associated with impending ulceration is much easier to see with dermoscopy and in some cases might allow for expedited treatment initiation when this cannot be appreciated with the naked eye. 5 Angiokeratomas are characterized by lacunae. However, the lacunae tend to have a more violaceous hue and may have more color variability within a single lesion (red, maroon, and blue). Black lacunae are also possible and represent areas of local thrombosis.

Introduction. Nevus sebaceous of Jadassohn (synonym: nevus of the sebaceous glands) (NSG) presents the congenital malformation of the skin with possible transformation into benign or malignant tumors during the adolescence or adulthood. Commonly appeared on the scalp or neck NSG is frequently concern with cosmetic problems making patients look for opportunities for its removal. Surgical removal of the NSG is related to an elevated risk of scarring. Using ablative lasers has proven to be effective in the removal of small NSG. However, the removal of medium and large NSG with ablative lasers was reported to be linked with a high risk of scarring and recurrence. The removal of the medium-sized NSG with a copper vapor laser (CVL) is described here for the first time. Case report and procedure. Laser removal of NSG (linear sized of 27 mm) was performed in a 25-year-old female patient with Fitzpatrick skin type II during eight CVL treatments. Laser settings were selected as follows: the average power of 1 W at the power ratio of 3:2 radiation at a wavelength of 511 and 578 nm. Pulse duration 20 nanoseconds, reprate 16.6 kHz, exposure duration 200 ms, and the light spot's diameter on the skin 1 mm. Results. After 8 procedures, the skin in the area of the removed NSG acquired a natural color and appearance. During 24 months of follow-up, there was no hyperpigmentation or signs of scars in the irradiated area. No relapses were observed for 24 months after the CVL removal of NSG. Conclusion. The application of non-ablative CVL removal of NSG ensured a desired cosmetic result without side effects.

Sebaceous nevus is a congenital hamartoma commonly associated with the development of secondary neoplasms. It has a predilection for the scalp and less commonly manifests on the face, the neck, and the trunk. The lesions presented in our cases are from the trunk of a 19-year old man, the forehead of a 25-year old man, the scalp of a 22-year old woman and from the face of a 45-year old man. Two of four cases were associated with secondary neoplasms, syringoma and basal cell carcinoma. Dermoscopy of nevus sebaceous demonstrated yellowish-brown globular structures, presenting either singly or in clusters and pink-brown-grey papillary appearance. The specific dermoscopic findings in our case associated with basal cell carcinoma were fine arborizing and serpiginous vessels at the periphery of the lesion and exophytic grey papillary structures. Dermoscopy can be a useful diagnostic tool for diagnosing and monitoring nevus sebaceous in order to detect different tumors associated with nevus sebaceous and avoid unnecessary excisions and scars in aesthetically sensitive locations.
