Article Synopsis
  • Dermoscopy is an important noninvasive technique that helps in the diagnosis of melanoma and can aid in assessing its thickness before surgery.
  • This study examined the relationship between blood vessel morphology in primary melanomas and factors like the Breslow index (a measure of melanoma thickness) and ulceration.
  • Results indicated that certain types of blood vessels are linked to thicker melanomas and that specific vessel types may indicate ulceration or dermoscopic regression, though the study faced challenges with case selection and identifying vessels in pigmented melanomas.

We report on a child with a divided or kissing nevus of the penis with benign symmetric globular pattern on dermoscopic examination that evolved into a globular-reticular pattern after 1 year of follow-up. Divided nevus of the penis is exceedingly rare, with only four cases with dermoscopic findings reported to date. Dermoscopy seems to be useful when deciding on the most appropriate management of these cases.

Background: The genetic basis of melanoma affects its clinicopathologic characteristics and increasingly influences its management. B-Raf proto-oncogene, serine/threonine kinase gene (BRAF)-mutated melanoma may present with specific dermoscopic features.

Objectives: To identify the dermoscopic features associated with BRAF mutation in cutaneous melanoma and to evaluate a model capable of predicting BRAF mutations on the basis of dermoscopic and clinicopathologic features that are easily accessible in normal clinical practice.

Thrombocid® ointment (Lacer, Barcelona, Spain) is widely used in Spain and other countries for varicose veins and 22 hematomas. To our knowledge, there are no reported cases of allergic contact dermatitis following its use. Herein we present 23 two cases of allergic contact dermatitis to Thrombocid® ointment, owing to cetearyl alcohol.

Perineuriomas are rare tumors derived from perineural cells usually presenting as a single asymptomatic papule or nodule located on an extremity of an adult. A sclerosing subtype has been rarely described. We report a case of painful sclerosing perineurioma in a 42-year-old woman.

The rosette structure is a dermoscopic sign visible under polarized light, characterized by 4 white points arranged as a 4-leaf clover. It has been mainly described in facial sun-damaged skin and actinic keratosis, although it has also been found in squamous and basal cell carcinomas, and in 2 cases of hypomelanotic melanomas. We describe 2 different cases of pigmented incipient melanomas with the presence of multiple rosettes and shiny white structures on dermoscopy.

Omalizumab is a monoclonal anti-IgE antibody approved for the treatment of severe allergic asthma. There is increasing evidence in the literature of its usefulness in chronic urticaria. Herein, we report a retrospective case series of 15 patients with chronic idiopathic urticaria treated with omalizumab.
