Acquired perforating dermatosis: a report of 8 cases.

Acquired perforating dermatosis (APD) is an uncommon disease characterized by lesions exhibiting transepidermal elimination of collagen or elastic fibers. APD affects adults and is associated with systemic diseases, mainly diabetes mellitus and renal failure. We present 8 cases of APD.

Elastolytic giant cell granuloma: clinic-pathologic review of twenty cases.

Background: O'Brien described four histopathological patterns of actinic granuloma (AG). Since then, only single cases and a few series have been reported in the literature, most corresponding to cases of the giant cell type.

Methods: We reviewed all the cases diagnosed as AG or elastolytic giant cell granuloma (EGCG) in our department from 1988 until 2010.

Photodistributed erythema multiforme.

Although the existence of photodistributed erythema multiforme has been recognized for years, few cases have been described to date. It is an uncommon, and probably underdiagnosed, skin disorder that can affect individuals of both sexes and all ages. It has been associated with drugs, reactivation of herpes simplex virus infection, and polymorphous light eruption.

Psoriasis, psoriatic arthritis and type 2 diabetes mellitus: a systematic review and meta-analysis.

Several observational studies have assessed the association between psoriasis, psoriatic arthritis (PsA) and type 2 diabetes mellitus, with inconclusive results. We set out to investigate the association between psoriasis, PsA and type 2 diabetes mellitus. Observational studies assessing the relationship between psoriasis or PsA and type 2 diabetes mellitus up to December 2012 were identified by electronic and hand searches in Medline, Embase, PubMed, the Cochrane Database of Systematic Reviews and Google Scholar.

Photosensitivity due to thiazides.

Thiazides are widely used diuretics that first became available in the 1950s. The first reports of photosensitivity reactions to thiazides were published shortly after the introduction of these drugs, but few cases have been described since. We review all the cases of photosensitivity due to thiazides published up to December 2011.

Cutaneous collagenous vasculopathy: description of two new cases in elderly women and review of the literature.

Cutaneous collagenous vasculopathy (CCV) is an idiopathic microangiopathy with characteristic histological findings. It was described in 2000, and 9 cases have since been described. Two women of 83 and 74 years consulted for long-standing telangiectasias.

Granuloma annulare photoinduced by paroxetine.

Granuloma annulare (GA) is a benign granulomatous skin disease with several clinical manifestations and characteristic histological findings. GA located in photoexposed areas is a rare finding and its association to a drug-induced systemic photosensitivity is even less common. To the best of our knowledge, only one case of systemic drug photosensitivity manifesting as a GA has been reported.

Systemic photosensitivity due to Goji berries.

Systemic photosensitivity due to the intake of plants or herbal compounds is a rare phenomenon. Goji berries are widely used as a well-being and anti-aging remedy. In spite of this, only a few adverse reactions and no cases of photosensitivity have been reported to date.

Erythema multiforme photoinduced by paroxetine and herpes simplex virus.

Erythema multiforme (EM) is a self-limited skin disease, characterized by the abrupt onset of symmetric red papules that may evolve into target lesions often precipitated by an infection. Photosensitive erythema multiforme (PEM) is a rare disorder characterized by the distribution of the lesions on sun-exposed areas. It has been described at the sites of sunburn, following episodes of polymorphic light eruption or herpes labialis and in association with drugs.

Systemic photosensitivity due to a contraceptive patch.

Hormonal contraceptives are a known but rarely reported cause of photosensitivity. A 35-year-old female developed several episodes of a prurigionous papulovesicular eruption located on sun-exposed areas that resolved without scarring in days. She had been using a transdermal contraceptive (EVRA: norelgestromin and ethinyloestradiol) for 3 years, and once it was stopped, the patient became asymptomatic.
