This article provides a detailed review of the vascular manifestations affecting the skin in relationship to internal malignancies. Vascular abnormalities heralding internal malignancies can be divided into three main categories, consisting of disorders related to vascular dilatation (flushing, palmar erythema, and telangiaectasia), and disorders related to vascular occlusion or hypercoagulability states (purpura, cutaneous ischemia, and thrombophlebitis). Entities are discussed according to etiology. The treatment of these entities is mostly related to treating the underlying malignancy. The goal of this article is to enlighten the practicing dermatologist about the association of these vascular manifestations with internal malignancy, thus leading to prompt initiation of the proper workup and management.

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.

Erythema Toxicum, a rash frequently present in the healthy newborn infant is an innate, immune response to the first commensal micro flora. Flushing and urtication are seen in this manifestation suggesting mast cell (MC) activation and MC derived mediator release. It has recently become evident that MCs participate in the protective, innate immune response against microbes also by secreting products toxic to pathogens such as cathelicidin peptide antibiotics. We hypothesized that MCs contribute to the process of inflammation in Erythema Toxicum and that skin MCs of human newborns express the cathelicidin peptide antibiotic LL-37. Skin sections were immunostained for MC tryptase. Double immunofluorescence was performed by staining LL-37 in combination with tryptase. We studied ultra structure of skin MCs with transmission (TEM) and immunoelectron microscopy (IEM). Seven infants with and six infants without the rash, as well as three adults were included. We found numerous tryptase-expressing MCs recruited around the hair follicles in the lesions of Erythema Toxicum. TEM analysis of MCs exhibited signs of degranulation in the lesion. Neither skin MCs from newborns nor adults did express LL-37 as judged by confocal and IEM. MCs participate in the inflammatory responses of Erythema Toxicum by taking an active part in the immune system of the hair follicle. However, their immunological activity is not linked to the expression of the cathelicidin antimicrobial peptide LL-37. A pivotal role of MCs in the innate, inflammatory response at the site of pathogen invasion during the critical time of perinatal colonization is suggested.

Although the reported incidence of hypersensitivity reactions (HSR) to antineoplastic agents is considered to be uncommon, it is difficult to evaluate their exact prevalence, mainly because their definition is vast and pathogenic mechanisms are vague. HSR include facial flushing, erythema, pruritus, fever, tachycardia, dyspnea, tongue swelling, rash/hives, headache, chills, weakness, vomiting, burning sensations, dizziness, and edema. Treatment and prevention consists of slowing the infusion rate, steroids, and type 1 and 2 histamine receptor antagonists. Desensitization could allow the small number of patients who experience severe HSR to receive effective therapy for their cancer. Reintroductions have only been reported as single case studies or small cohorts. Large-scale validation on desensitization strategies is still missing. With regard to oxaliplatin, knowledge of its rare but eminent toxicity is paramount, because this drug is widely used in treating colorectal cancer, the second-highest cause of cancer mortality in the United States.

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.

We report a case of a 44-year-old woman with an 8-year history of gnatophyma. Rosacea is a facial dermatosis that may present as flushing, erythema, telangiectases, papules, pustules and phyma. Phyma is considered the final evolution stage of rosacea and is a rare variant. Treatment of phyma with atypical localization may be a challenge for dermatologists in clinical practice.

Rosacea is a common chronic inflammatory disorder which occurs most often in middle-aged women characterized by symptoms of facial flushing and a spectrum of clinical sings including erythema, telangiectasia, burning, coarseness of skin and an inflammatory papulopustular eruption resembling acne. The aim of the study was to evaluate the quality of life in people with rosacea and healthy controls. Forty people with rosacea and 40 people without skin lesions were the subjects of the study. The quality of life was measured using standard questionnaire SF-36 (Short Form 36 Health Survey). The obtained results revealed that, in comparison to the control group, patients with rosacea presented reduced quality of life in subgroups: general health, vitality, emotional sphere, physical functioning, mental health and bodily pain. Outcomes show that rosacea plays a an important role in patient's quality of life and revealed the need to cooperate with psychologists and support groups.

Sorafenib is a new therapeutic agent being used in metastatic renal cell carcinoma, hepatocellular carcinoma, and malignant melanoma. The most frequently seen cutaneous side effects due to sorafenib are erythema, exfoliative dermatitis, acne vulgaris, and flushing. Folliculitis, eczema, and erythema multiforme are other, rare side effects of sorafenib. A 59-year-old man underwent left radical nephrectomy due to renal cell carcinoma 8 months ago, and after the operation he received immunochemotherapy and then sorafenib. On the third day of sorafenib therapy his lesions occurred. His dermatologic examination revealed multiple erythematous papules on his neck, arms, and legs and bullae and iris lesions on his palms and soles. He was diagnosed as having erythema multiforme. In the literature we found only 1 other erythema multiforme case due to sorafenib. We present this interesting case to show and discuss cutaneous side effects of sorafenib, especially erythema multiforme as a very rare cutaneous side effect.

Rosacea is a common chronic, and sometimes progressive, dermatosis. It is characterized, alone or in combination, by central facial erythema,symmetric flushing, stinging sensation, inflammatory lesions (papules and pustules), telangiectasias, and phymatous changes (tissue hyperplasia and nodules). Rosacea can occur in adults of any ethnicity,and adversely affects patients' quality of life. The condition can be effectively controlled with therapy tailored to the specific subtype of rosacea that is affecting the patient. Topical metronidazole, sulfacetamide/sulfur, and azelaic acid are generally effective for patients with mild rosacea. For moderate papulopustular rosacea, combination therapy with oral tetracyclines and topical agents is the first-line choice. Treatment with a topical agent, such as metronidazole, may help maintain remission. Patients with ocular involvement may benefit from long-term oral antibiotics and metronidazole gel. Referral to a subspecialist is necessary for patients who have ocular rosacea with ophthalmic complications, severe or recalcitrant rosacea, or phymatous changes.

Erythematotelangiectatic skin is a common cosmetic and medical problem. Flushing or persistent erythema, teleangiectasias, and occasionally other inflammatory skin lesions can be caused by internal or environmental factors. Certain physiologic reactions and systemic or dermatologic diseases represent internal conditions leading to visible skin flushing in the blush area. Erythematotelangiectatic skin is found in body areas which are particularly exposed to various environmental factors and perform important esthetic functions at the same time. Determination of the main etiopathologic factor responsible for flushing in the blush area precedes the selection of an adequate method of care, correction or treatment of the erythematotelangiectatic skin. The main aim of this study was to analyze fundamental mechanisms of flushing or persistent erythema and their sequellae basing on the literature. Another aim was to review current diagnostic options useful in examining the etiology and severity of erythematotelangiectatic skin symptoms.
