Solar urticaria: a time-extended retrospective series of 61 patients and review of literature.

Background: Solar urticaria is a rare, disabling, chronic disease. Few large series are available.

Objective: To report the epidemiological, clinical, phototesting, treatment and patient outcome data of a large series.

Solar urticaria treated with intravenous immunoglobulins.

Background: Solar urticaria (SU) is a rare idiopathic photodermatosis induced immediately after sun exposure. This disorder may considerably restrict normal daily life and management is extremely difficult when treatment with oral H1 antihistamines and sun avoidance are ineffective.

Objective: We sought to report the effectiveness of intravenous immunoglobulins (IVIG) in severe SU.

Octocrylene, an emerging photoallergen.

Background: Octocrylene is a new emerging photoallergen. We report and discuss 50 cases of photoallergic contact dermatitis from octocrylene use and/or positive photopatch test reactions to this UV filter and draw attention to the unexpected association in adults with a history of photoallergic contact dermatitis from ketoprofen.

Observations: Patients were divided in 3 groups: group A comprised 11 children; group B, 28 adults with a history of photoallergy from sunscreen products; and group C, 14 adults systematically tested with octocrylene because of a history of photoallergy from ketoprofen.
