Divided or kissing nevus of the penis: A new case with dermoscopic findings.

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.

The association between dermoscopic features and BRAF mutational status in cutaneous melanoma: Significance of the blue-white veil.

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.

Allergic contact dermatitis from cetearyl alcohol in Thrombocid® ointment.

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.

Sclerosing perineurioma: case report and literature review.

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.

Dermoscopic rosettes as a clue for pigmented incipient melanoma.

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 in chronic urticaria: a retrospective series of 15 cases.

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.
