Calcium antagonists (CAs) or calcium-channel blockers, are a common group of antihypertensive medications. These drugs have the property of blocking the calcium channels of the vascular and cardiac smooth-muscle fibers. They have been associated with cutaneous reactions ranging from exanthems to severe adverse events. The frequency of these reactions may be as high as 48 percent. The most common are ankle or pedal edema (up to 30 %), gingival hyperplasia (up to 21 %), and flushing (up to 10 %). Less common are facial or truncal telangiectasia, photosensitivity reactions, new-onset psoriasis (as well as exacerbation of it), purpuric exanthems, pemphigoid manifestations, subacute cutaneous lupus erythematosus, gynecomastia, erythromelalgia, and oral ulcers. Particular adverse manifestations relate to drug potency, degree of vasodilatation, patient age, coexistence of other diseases, co-administration of other cytochrome P450 CYP3A-metabolized medications, fibroblast stimulation, and blood cell effects. Calcium antagonists are associated with a wide range of skin reactions, and the dermatologist should include these in the differential diagnosis of cutaneous diseases.

Rosacea is a chronic disorder characterized by hypersensitivity of the facial vasculature, presenting with intense flushing eventually leading to chronic erythema and telangiectasia. Although the precise aetiology of rosacea is not known, numerous associations with inflammatory gastrointestinal tract disorders have been reported. Furthermore, substance P-immunoreactive neurones occur in considerably greater numbers in tissue surrounding affected blood vessels suggesting involvement of neurogenic inflammation and moreover plasma kallikrein-kinin activation is consistently found in patients. In this report, a patient without digestive tract disease is described, who experienced complete remission of rosacea symptoms following ingestion of a material intended to sweep through the digestive tract and reduce transit time below 30 h. It is possible that intestinal bacteria are capable of plasma kallikrein-kinin activation and that flushing symptoms and the development of other characteristic features of rosacea result from frequent episodes of neurogenic inflammation caused by bradykinin-induced hypersensitization of facial afferent neurones. The possible relevance of this hypothesis to other conditions featuring afferent hypersensitivity, such as fibromyalgia, is considered.

Pharmacologic agents remain the mainstay for initial and maintenance treatment of rosacea. However, monochromatic (i.e., laser) and polychromatic light-based therapies are increasingly being used for the treatment of certain signs of rosacea. Despite the increased use of lasers and other light-based therapies, few well-controlled studies have been conducted on their use for the treatment of rosacea. The studies that do exist suggest that these modalities have value in treating erythematotelangiectatic rosacea, including persistent erythema and phymatous rosacea. Light-based therapies should be strongly considered in cases of serious erythema, flushing, and telangiectasia because these signs are not optimally addressed by pharmacologic interventions.

A 55-year-old Caucasian man presented to a plastic surgeon for the treatment of two lesions on his nose, first a chronic indented area with some telangiectasia on the proximal nasal bridge (Figure 1) and second a hyperkeratotic nodule with central crusting on the ala nasi that developed rapidly over several weeks (Figure 2). The surgeon appropriately diagnosed the ala nasi nodule as a squamous cell carcinoma, keratoacanthoma type, but requested an opinion from dermatology for the proximal nasal bridge indentation that he suspected to be a morpheaform or erosive basal cell carcinoma possibly requiring Mohs micrographic surgery. Upon further questioning, the patient revealed that he has had persistent erythema and problems with facial flushing for many years, particularly with alcohol, coffee, and moderate exercise. He infrequently develops papulopustular lesions. Closer clinical inspection revealed a mild erythema, telangiectases, and a hypertrophied nose. He noted that he wore an old heavy pair of glasses every day. He was notified of a coexisting diagnosis of rosacea, and various treatment options were discussed. He was pleased that he would not need any further surgery to his nose.

Acne rosacea is one of the most common diagnoses seen in the clinical dermatologic practice. The classic presentation of rosacea, acneiform papules, and pustules on a background of telangiectasia, is often easily identified by primary care physicians, patients, or their similarly afflicted friends or family members. However, rosacea actually represents a spectrum of disease from chronic skin hypersensitivity and flushing to rhinophyma. Although the pathogenesis of rosacea remains unknown, it is important to understand its various presentations and possible etiologies prior to developing individualized treatment protocols.

Acne rosacea is a multifactorial, somewhat mercurial disorder that can be a challenge to control with standard pharmacologic agents. Laser and light sources have been increasingly utilized, particularly for control of the generalized erythema, flushing, and telangiectasia of rosacea. This paper will review the clinical studies presented in the literature specifically treating patients with rosacea. Long-pulsed dye lasers and intense pulsed light devices can offer patients effective treatment without the purpura of short-pulsed dye lasers. Long-term efficacy has not been studied but maintenance therapy may be necessary to control the vascular manifestations of this disease.

The most frequent site of organ involvement in patients with any form of mastocytosis is the skin. Cutaneous expressions include urticaria pigmentosa, mastocytoma, diffuse and erythrodermic cutaneous mastocytosis, and telangiectasia macularis eruptiva perstans. The cutaneous lesions tend to appear early in life. Although urticaria pigmentosa has been reported in 12 pairs of twins and one set of triplets, the majority of affected individuals have no familial association. Most patients with systemic mastocytosis have skin lesions; however, an occasional patient will have systemic disease with no other skin features than flushing. In lesional cutaneous sites and in non-lesional skin, there is an increase in the number of mast cells. Electron microscopy shows quantitative differences between lesional skin mast cells from patients with and without systemic disease. The mast cells from adult patients with systemic disease have a larger mean cytoplasmic area, nuclear size, and granule diameter. The granules contain predominantly grating/lattice structures. The cutaneous mast cells contain tryptase and chymase. They retain their functional reactivities to relevant secretory stimuli, such as C3a, morphine sulfate, and calcium ionophore A23187. Lesional skin contains histamine, leukotriene B4, prostaglandin D2, 5-hydroxyeicosatetraenoic acid, platelet-activating factor, and heparin. Treatment of the cutaneous manifestations includes the use of H1 and H2 antihistamines, oral disodium cromoglycate, psoralens plus ultraviolet A photochemotherapy, and potent topical corticosteroid preparations.

Rosacea is a chronic inflammatory skin disease characterized by recurrent episodes of facial flushing, erythema, papules, pustules, and telangiectasia. More than half of all rosacea patients may have ocular symptoms. Rosacea is associated with certain digestive diseases, such as gastritis, hypochlorhydria, or a number of jejunal mucosal abnormalities, and many patients have Helicobacter pylori infection. The role of Helicobacter pylori has often been a subject of investigation; these studies show conflicting results. Here we present results of the effects of treatment given for H. pylori eradication in seven patients with ocular rosacea that, at the same time, had clinical and serological evidence of H. pylori infection. Six weeks after completion of the treatment, all patients experienced improvement of their rosacea symptoms. Ocular disease responded better than cutaneous rosacea.

This short paper reviews the nature of rosacea emphasizing the possibility of a solar cause. The sites of involvement and the physical signs of rosacea including the flushing, the erythema and the telangiectasia as well as the intermittent episodes of inflammation with swelling and papules may all be explained by UVR induced damage to dermal connective tissue. The dermal damage permits vaso-dilation and vascular pooling.

Rosacea is a chronic inflammatory skin disease appearing in the central area of the face of middle-aged patients. It is characterized by flushing, permanent erythema, telangiectasia, papules, pustules, and the absence of comedones. Its underlying pathophysiological mechanisms are not completely understood, although a number of hypotheses point to vascular abnormalities and infection by microorganisms such as Demodex folliculorum. Rosacea is classified into 4 subtypes, which determine the therapeutic approach based on skin care, topical antiinflammatory agents, topical and oral antibiotics and retinoids, and, in some instances, light-based therapy and surgery.
