1/9. garlic-related dermatoses: case report and review of the literature.BACKGROUND: garlic is widely appreciated as a spice and as a vegetable as well as an over-the-counter phytotherapeutic. From a dermato-allergological standpoint, several garlic-related adverse reactions have to be distinguished. OBJECTIVE: The corresponding literature is reviewed briefly, with regard to our present observation of a cook, who contracted garlic-induced contact dermatitis being analyzed for its complex pathomechanism. methods: The patient showed a positive type-IV patch test reaction for diallyl disulfide, a low molecular weight garlic ingredient; and strong, non-irritant reactions after 20 min and 24 hrs in the scratch chamber test with fresh total garlic. RESULTS: Thus, in this case of an occupational dermatosis, protein contact dermatitis had to be considered, as well as allergic type-IV contact dermatitis as a co-existing pathomechanism. CONCLUSIONS: The spectrum of garlic-related adverse reactions comprises irritant contact dermatitis, with the rare variant of zosteriform dermatitis; induction of pemphigus, allergic asthma and rhinitis; contact urticaria; protein contact dermatitis; allergic contact dermatitis, including the hematogenic variant; as well as combinations thereof, as evidenced by our present case observation.- - - - - - - - - - ranking = 1keywords = dermatosis (Clic here for more details about this article) |
2/9. Facial orf.Orf is an occupational dermatosis caused by a poxvirus that infects sheep or goats. Human transmission typically occurs in people in contact with the infected animals or by handling contaminated animal products such as wool or meat. The infection in humans is classically characterized by a solitary papule on the fingers or hands. Involvement of the face or head has rarely been reported. We report orf in a young woman with multiple nodules on the face.- - - - - - - - - - ranking = 1keywords = dermatosis (Clic here for more details about this article) |
3/9. Juvenile spring eruption: clinicopathologic features and phototesting results in 4 cases.Juvenile spring eruption is a distinct photodermatosis characterized by the development of papules and vesicles on light-exposed areas of the ears usually in the early springtime. It primarily affects boys and young men, and has a tendency to occur in the form of small epidemics. We report a similar outbreak in separate groups of soldiers who were performing military exercises during cold and sunny weather of a midwinter season. The clinicopathologic features and phototesting results are described in 4 of these cases. All patients showed normal erythemal responses to monochromator phototesting with UV and visible wave bands. Photoprovative testing with repeated daily exposures of the ears to a broadband UVA source provoked diffuse erythema and itching in 1 case, whereas similar photoprovocation of a nonaffected area, ie, the flexor surface of the forearm, in 2 patients did not yield a skin reaction. Although the cause of juvenile spring eruption is not known, our observations further strengthen the hypothesis that the disorder is a localized variant of polymorphous light eruption.- - - - - - - - - - ranking = 1keywords = dermatosis (Clic here for more details about this article) |
4/9. Phytophotodermatitis in grounds operatives.Occupational dermatoses account for a significant proportion of work-related morbidity. Phytophotodermatitis is an unusual work-related dermatosis, but should be considered in the differential diagnosis of such conditions. An outbreak of 'strimmer rash' is described in three grounds operatives. The identification, aetiology and management of the condition are discussed.- - - - - - - - - - ranking = 1keywords = dermatosis (Clic here for more details about this article) |
5/9. The edema of fiddler's neck.Fiddler's neck is a dermatosis of violinists and violists. It characteristically presents as focal lichenification and pigmentation on the left side of the neck. edema may also occur in the same area and lead to cosmetic concern or fear of malignancy. The edema apparently results from pressure on the patient's neck by the base of the violin or viola and is worsened by holding the instrument in a drooping position.- - - - - - - - - - ranking = 1keywords = dermatosis (Clic here for more details about this article) |
6/9. Barber's hair sinus in a female hairdresser: uncommon manifestation of an occupational dermatosis.Hairdressers are prone to developing occupational skin diseases, particularly hand eczema of different origins. Rather uncommon, however, is the so-called barber's hair sinus that is caused by hair fragments penetrating the skin preferably in the interdigital spaces of their hands. Whereas, to date, the disease has almost exclusively been reported to occur on the hands of male hairdressers, we herein present the first case of a female hairdresser who developed a barber's hair sinus on one of her feet.- - - - - - - - - - ranking = 4keywords = dermatosis (Clic here for more details about this article) |
7/9. Pulling boat hands: a unique dermatosis from coastal new england.We report a previously unrecognized hand dermatosis, pulling boat hands (PBH), occurring in thirteen participants at the Outward Bound School on Hurricane Island, maine. Painful and pruritic macules, plaques, and vesicles developed exclusively while subjects lived aboard a pulling boat, the school's open rowing/sailing craft. Nine of those affected were women and eight had Raynaud's phenomenon or vasospasm. These subjects experienced thirty episodes of PBH during May through October, 1978 to 1982. Histopathology revealed a superficial and deep lymphohistiocytic perivascular infiltrate, subepidermal blister formation, red blood cell extravasation, and dermal capillary thrombosis compatible with cold injury to the skin. All patients experienced prolonged percussion to their hands while rowing as well as a continuous environmental exposure to cold air, wind, humidity, ocean spume, and precipitation. These clinical, histopathologic, and environmental findings suggest a unique syndrome that combines the vascular effects of mechanical trauma from rowing with those of nonfreezing cold injury.- - - - - - - - - - ranking = 5keywords = dermatosis (Clic here for more details about this article) |
8/9. Drywall stilt dermatosis.We describe a previously unreported occupational dermatosis occurring in a worker employed in drywall installation and finishing. This 50-year-old man presented with bilaterally symmetrical, parallel, linear crusted erosions on his anteromedial legs after wearing drywall stilts. The pathophysiology of this condition is considered.- - - - - - - - - - ranking = 5keywords = dermatosis (Clic here for more details about this article) |
9/9. Spiny keratoderma: a common under-reported dermatosis.Spiny keratoderma is a dermatosis consisting of multiple projections located on the palms and soles, with a distinct histology characteristic of a parakeratotic column above a hypogranular epidermis. We report six cases discovered within a year and review the present literature on spiny keratoderma. The average age of the patients was 57 years. Fifty-seven percent of the patients were male and forty-three percent were female. The duration of lesions ranged from 4 months to 40 years. Symptoms were variable, however, lesions were often unnoticed by the patient. The location of the lesions involved the palms and soles or the palms alone. Past medical history was significant for hypertension and hyperlipidemia treated with HMG-CoA reductase inhibitors. Lesions often occurred in patients involved in manual labor. Spiny keratoderma is a relatively common under-reported dermatosis found most often in older patients with history of manual labor and is possibly related to treatment with HMG-CoA reductase inhibitors.- - - - - - - - - - ranking = 6keywords = dermatosis (Clic here for more details about this article) |
