A 55-year-old male developed itching on the anterior aspects of both legs and the right ankle. Gradually over the next 5 years there was thickening of the skin on these areas followed by the appearance of hyperpigmented, scaly, severely itchy plaques. He also noticed the appearance of a thick, hard horn-like structure projecting from the surface of the right ankle lesion for the last 2 years. A...

A 44-year-old woman presented at our department in 2003 with multiple pruritic papules spread over her trunk and extremities, and was diagnosed with LP. No mucosal lesions were observed. The diagnosis was histologically confirmed. Viral infection, contact with triggering substances, and use of medications were all ruled out. Treatment with sulfasalazine was begun and 5 months later, the lesions...

A 76-year-old woman with hypertension and hepatitis C presented with a 10-year history of sclerotic, atrophic, ivory-white plaques with violaceous borders on the upper part of her trunk and on her arms, waistline, and anogenital areas (Figure 1). The plaques were gradually extending and becoming more pruritic. A biopsy revealed findings diagnostic of lichen sclerosus (LS), including an atrophic...

BACKGROUND AND AIM Ingenol mebutate (IngMeb) is an effective treatment for actinic keratosis. In this study, we hypothesized that repeated treatments with IngMeb may prevent progression of UV-induced photodamage, and that concurrent application of a corticosteroid may reduce IngMeb-induced local skin responses (LSR). METHODS Hairless mice (n = 60; 3 groups of 20 mice) were irradiated with sol...

In a survey on work-related skin problems in professional ice hockey players one player developed a severe patch test reaction with an unexpected complication. The positive reaction to diethyl thiourea was vesiculo-bullous, oedematous and significantly elevated and a spreading several centimeters outside the test area was noted. Starting less than 24h after the patch test application, itching e...

We report a case of an allergic skin reaction to ultraviolet-cured acrylates in a windscreen repair worker. The patient presented with a 6 month history of fingertip dryness, vesicles and desquamation. He had worked as a self-employed car windscreen repairer for 19 years. Previous management with vinyl glove protection and treatment with clobetasol propionate ointment had produced little improv...

Pyoderma gangrenosum (PG) is a rare inflammatory neutrophilic dermatosis often misdiagnosed. It is uncommon in infants and children accounting for 4% of cases. A one-year-old male in paediatric ICU ventilated for bronchopneumonia was referred with ulcerated areas on his neck and axilla corresponding to sites of recent removal of central and arterial lines. Examination revealed areas of deep ulc...

BACKGROUND Lichen sclerosus is an inflammatory disease of unknown etiology affecting the anogenital skin and associated with the development of squamous cell carcinoma. It is not known whether long-term topical treatment with a potent steroid can cure this disease and thus prevent malignant evolution. OBJECTIVES To analyze the rates of remission, recurrence, and chronic evolution of vulvar li...

Topical steroids have been widely used in the treatment of symptomatic oral lesions to reduce pain and inflammation. Potent topical steroids such as clobetasol propionate, fluocinolone acetonide (FA), and fluocinonide have been widely used in the treatment of severe oral mucosal lesions. Many reports have demonstrated that these steroids were effective in treating oral lesions with only minor s...

Bullous morphea is a rare form of morphea characterized with bullae on or around atrophic morphea plaques. Whereas lichen sclerosus et atrophicus (LSA) is a disease the etiology of which is not fully known, and which is characterized with sclerosis. Coexistence of morphea and LSA has been identified in some cases. Some authors believe that these two diseases are different manifestations which a...
