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.

Carcinoid tumors are the most frequent gut neuroendocrine tumors accounting for more than 50% of all tumors of the gastroenteropancreatic (GEP) axis. These tumors appear to derive from a stem cell line capable of differentiating into a variety of malignant cells that secrete many different peptides and amines. The symptoms of carcinoid tumors are often non-specific, vague abdominal pain that may precede the diagnosis by a median of 9 years. Carcinoid syndrome occurs in less than 10% of patients. We evaluated the effects of SMS 201-995 in 14 such patients, 12 with diarrhea, 8 with flushing, 3 with wheezing, one with tricuspid valve incompetence, 6 with facial telangiectasia, 3 with a pellagra type dermatosis and one with myopathy. Diarrhea was abolished or significantly reduced in 83%, flushing in 100%, wheezing in 100%, and myopathy improved in the one patient. Blood serotonin was resistant to change, urine 5HIAA fell in 75%, and most gut neuropeptide hormones apart from somatostatin were suppressed. Tumor growth appeared to be slowed in 2/3 of cases treated for up to 4 years. The analog of somatostatin appears to be a useful addition to the therapeutic armamentarium for carcinoid tumors and the symptom complex.

Five months after starting nifedipine (Adalat), two patients developed photodistributed facial telangiectasia, which became more noticeable with time. Neither patient complained of photosensitivity or flushing. Both patients reported a significant cosmetic improvement after discontinuing the drug. One commenced the closely related drug amlodipine 3 years later, with recurrence of telangiectasia. The photodistribution of the telangiectasia suggests a significant drug/light interaction.

Acne rosacea is a common skin condition characterized by flushing episodes, erythema, telangiectasia, and recurrent crops of inflammatory papules and pustules that involve the face in a symmetrical distribution. A pilot study was conducted to compare topical 5 percent permethrin cream and 0.75 percent metronidazole gel in the treatment of acne rosacea. Six patients began treatment with 0.75 percent metronidazole gel twice daily to the right side of the face and permethrin 5 percent cream applied daily to the left side. Clinical evaluation was performed every two weeks. Five patients completed the study. The patients were treated for a range of seven to ten weeks. There were minimal adverse effects. Moderate improvement was seen on both sides.

We report a 20-year-old female patient with telangiectasia macularis eruptiva perstans characterised by telangiectatic macular lesions and episodic flushing, two lesions of which were successfully treated by laser. Two clinically different forms of cutaneous mastocytosis have both been previously described as telangiectasia macularis eruptiva perstans, and we now propose that this term be restricted to cutaneous mastocytosis characterised by the typical telangiectatic macules.

Rosacea is one of the most commonly occurring inflammatory dermatoses treated by dermatologists today. Estimates suggest that at least 13 million Americans have recognized rosacea, and the clinical experience of most practitioners would add considerably more to that number. Rosacea is an inflammatory condition of the skin, classically presenting with a history of flushing and/or blushing along with the clinical findings of erythema, edema, telangiectasia, papules, pustules, and nodules of the face. Severity and distribution vary considerably. A patient may have only a few scattered papules and pustules of the central third of the face or there may be numerous inflammatory, painful, tender, large nodules. In some cases, only the face may be affected. In other cases, there may be lesions of the scalp, neck, and/or torso. Although the exact etiology is unknown, rosacea is thought by most experts to be an inflammatory process incited by vascular instability with subsequent leakage of fluid and inflammatory mediators into the dermis.

Varieties of the clinical features of mastocytoses, also called mastocytosis syndrome, are presented. The disease is characterized by excessive accumulation of mast cells, their proliferation and action in the skin and other organs, even in the central nervous system. The mastocytosis syndrome was known as early as the second half of the 19th century under the term urticaria pigmentosa, and was histologically confirmed by the presence in the dermis of metachromatic cells, i.e. Ehrlich mast cells with red-purple cytoplasmic granules visible with Giemsa or toluidine blue stains. The mastocytosis syndrome was then supposed to be a benign chronic dermatosis of childhood with spontaneous regression by adolescence. The clinically pathognomonic symptoms of Darier's sign (urtication of primary skin lesion upon rubbing) and flushing help in the diagnosis of mastocytosis syndrome. In the 1950s, there was a progression in the diagnosis of systemic mastocytosis achieved by scientists and clinicians of various specialties. Upon the discovery of many mast cell released mediators (heparin, histamine, leukotrienes, prostaglandins, proteases, cytokines), receptor functions, relationship to IgE, anaphylatoxin, etc., they were recognized as triggers of various clinical features of the mastocytosis syndrome. In this paper, different forms of cutaneous and systemic mastocytosis are described, with special reference to 'mastocytosis mucocutanea haemorrhagica' observed by one of the authors in a female infant and followed from 6 months till 2.5 years of age. The patient showed practically all the diverse forms of cutaneous mastocytosis: urticaria pigmentosa, papular, nodular, tumorous-like melanoma, vesiculobullous, erythrodermic, telangiectasia eruptiva maculosa perstans. She also suffered from nasal and rectal hemorrhage, conjunctival suggillations, plaque-like infiltrations of the glossal, oropharyngeal and laryngotracheal mucosa, episodes of flushing, and transitory apnea. It is emphasized that the diagnosis of mastocytosis syndrome may be difficult for its mimicking various other diseases. The occurence of mastocytosis syndrome from the neonatal period through adult and old age, and possibilities of symptomatic treatment and prevention of sudden death or fatalities are discussed. Familial occurrence of mastocytosis syndrome and new genetic studies that may prove highly useful for understanding the etiopathogenesis of mastocytosis syndrome are described.

The response of rosacea-associated erythema and telangiectasia to treatment with the pulsed tunable dye laser (PDL) was evaluated in 12 patients. Improvements in erythema, telangiectasia, flushing, the physician's and the patient's perception of overall severity, treatment tolerability, and the adverse side effects were examined. With the sole exception of the patient's assessment of overall severity we have found highly significant improvements in all other parameters evaluated, with excellent tolerance of treatment. We therefore conclude that the PDL is a safe and effective treatment for the erythemato-telangiectatic component of rosacea.

Rosacea is a common, but often overlooked, skin condition of uncertain etiology that can lead to significant facial disfigurement, ocular complications, and severe emotional distress. The progression of rosacea is variable; however, typical stages include: (1) facial flushing, (2) erythema and/or edema and ocular symptoms, (3) papules and pustules, and (4) rhinophyma. A history of exacerbation by sun exposure, stress, cold weather, hot beverages, alcohol consumption, or certain foods helps determine the diagnosis; the first line of treatment is avoidance of these triggering or exacerbating factors. Most patients respond well to long-term topical antibiotic treatment. Oral or topical retinoid therapy may also be effective. Laser treatment is an option for progressive telangiectasis or rhinophyma. Family physicians should be able to identify and effectively treat the majority of patients with rosacea. Consultation with subspecialists may be required for the management of rhinophyma, ocular complications, or severe disease. (Am Fam Physician 2002;66:442.)

Rosacea is a common chronic dermatosis characterized by varying degrees of flushing, erythema, telangiectasia, edema, papules, pustules, ocular lesions, and phymas. Etiology and pathogenesis of rosacea are still unknown. Many possible causes have been described as inducing the disease or contributing to its manifestation, such as genetic predisposition, abnormal vascular reactivity, changes in vascular mediating mechanisms, Helicobacter pylori infection, Demodex folliculorum infestation, seborrhea, sunlight, hypertension, and psychogenic factors. However, none of these factors has been proved. Rosacea shows a wide spectrum of clinical presentations, which vary over time and with age. Successful management of rosacea requires careful patient evaluation and individualized therapy with appropriate variations and modifications, as the severity of the disorder fluctuates. In mild cases of rosacea, patients are instructed to avoid sun, to apply sun-protective creams, and to avoid facial irritants and other triggers that provoke symptoms. At later stage, drug therapy is often necessary. The disease commonly requires long-term treatment with topical or oral medicaments. Surgical correction may be required for rhinophyma and telangiectasia. We reviewed the current literature on the aspects of the pathogenesis, diagnostic criteria, and treatment options for rosacea.
