Lupus erythematosus with antiphospholipid syndrome and erythema multiforme-like lesions.

The occurrence of erythema multiforme (EM) in patients with lupus erythematosus (LE) has been described previously as a coincidental association. In contrast, LE with EM-like lesions and a peculiar immunological pattern, including positive rheumatoid factor, antinuclear antibodies and a serum antibody against an extract of human tissues recently recognized as similar to Ro (SSA), constitutes an established entity named Rowell's syndrome. We describe a woman with LE and long-standing widespread vesiculobullous and necrotic haemorrhagic EM-like lesions in combination with Ro (SSA) and scl-70 antibodies and the typical laboratory findings of the antiphospholipid syndrome (APS), namely lupus anticoagulant, anticardiolipin antibodies and prolonged activated partial thromboplastin time. This case could conceivably be consistent with a diagnosis of Rowell's syndrome, if the latter is regarded as a clinicopathological spectrum. However, the coexistence of LE, persistent EM-like disease and incomplete APS may also fulfil the diagnostic criteria for the 'multiple autoimmune syndromes'. We speculate that the laboratory markers of APS play a pivotal part in such an unusual clinical presentation.

A questionnaire study of road pavers' and roofers' work-related skin symptoms and bitumen exposure.

BACKGROUND: Skin contact with the components in asphalt and bitumen can lead to irritant and allergic contact dermatitis, but few data are available in the dermatologic literature on the skin symptoms caused by work with bitumen. In addition, working methods have changed markedly during recent decades. METHODS: A questionnaire was delivered to 50 roofers and 101 road pavers. The questionnaire dealt with skin symptoms, symptoms caused by solvent products, the use of personal protection, smoking, eating habits, work conditions, changing and cleaning of overalls, etc. RESULTS: Forty-eight per cent of the road pavers and 58% of the roofers responded to the questionnaire. Relatively high percentages of work-induced skin irritation were reported by both the roofers (44%) and the road pavers (31%); 22% of the road pavers had dermatitis often or sometimes compared with 15% of the roofers. The hands, arms, face, and lower extremities were the most common sites affected. In addition to bitumen products, the road pavers considered amine adhesion-improving agents for paving and naphtha and solvents used in machine repairs, to be the main causes of their skin symptoms. The skin problems of the roofers were caused by man-made mineral fibers, cutback bitumen, and hot bitumen burns. CONCLUSIONS: Roofers endure greater exposure to chemicals than road pavers. Certain components, e.g. polycyclic aromatic hydrocarbons in bitumen, can be absorbed through the skin. Skin exposure should be lowered by keeping the tools, working clothes, shoes, and gloves clean. Overalls and gloves are recommended to be changed at least once a week. Water laundering is not sufficient in dissolving bitumen from overalls and underwear. Cleaning the skin with solvents or naphtha is not recommended, as they are skin irritants.

The hyperkeratotic variant of disseminated superficial actinic porokeratosis (DSAP).

A 78-year-old South Korean man was referred to us from the Medical Intensive Care Unit (MICU) for an opinion. He was comatose and was on ventilatory care due to aspiration pneumonia. Multiple tiny papules had developed 10 years previously and since then the number and size had been increasing gradually. He had been diabetic for the past 4 years, and had Parkinson's disease diagnosed 1 year previously. Laboratory examinations revealed an elevated level of white blood cells (WBCs) (25,000/microL) and decreased hemoglobin (8.8 g/dL). Other laboratory results were negative or within normal limits. Skin examination showed multiple, discrete, crust-like, brownish papules over the erythematous base on the face, upper extremities, and lower extremities. With the clinical impressions of irritated verruca vulgaris, seborrheic keratosis, or cutaneous fungal infection, a skin biopsy was taken from a papule on the left shin, and histopathologic examination revealed several pronounced hyperkeratotic and parakeratotic columns, and characteristic cornoid lamellae in the stratum corneum. Beneath the cornoid lamellae, the granular layer was decreased. A number of round or oval, dyskeratotic, homogenized eosinophilic cells with pyknotic nuclei were scattered in the prickle cell layer below the cornoid lamellae. A mild lymphohistiocytic infiltrate was observed in the papillary dermis and around the blood vessels in the upper dermis. Also, actinic degeneration was present in the upper dermis.

The MOAHLFA index of irritant sodium lauryl sulfate reactions: first results of a multicentre study on routine sodium lauryl sulfate patch testing.

In a multicentre study of the German Contact Dermatitis Research Group, sodium lauryl sulfate (SLS) 0.25% and 0.5% aq. has been added to routine allergen patch tests to assess its properties as a convenient diagnostic indicator of individual susceptibility to irritation at the time of patch testing. Previous studies indicated that irritant SLS reactivity may be related to individual factors such as age and sex. As these factors are, in turn, among the important predictors of contact allergy to many allergens, e.g. summarized in the 'MOAHLFA index', the impact of the MOAHLFA factors on irritant SLS patch test reactivity, and thus a potential for confounding, was assessed in the 5971 participating patients. As a result of 2 logistic regression analyses with an irritant reaction to 0.25% and 0.5% SLS, respectively, as outcome, male sex was identified as a relatively weak but significant risk factor (OR 1.38), while age 40 years or older was an even weaker risk factor (OR 1.22 and 1.15, respectively). Upon detailed analysis, no clear age gradient could, however, be identified. 1-day exposure time almost halved the odds of an irritant SLS reaction. In conclusion, this type of SLS patch test can be regarded as robust, indicating individual irritability relatively independent from the individual factors analysed here.

Cutaneous horn: a brief review and report of a case.

A case of extensive verrucae vulgaris with cutaneous horns in a 32-year-old man is reported. Accompanying terminal phalangeal bone absorptive changes in the fingers of both hands, resulting from subungual warty lesions, are highlighted. The existing literature on the subject of cutaneous horn is briefly reviewed.

Chromoblastomycosis: report of two cases from Nepal.

Chromoblastomycosis is a chronic fungal infection of the skin and subcutaneous tissue caused by dematiaceous fungi. The first case, a 67-year-old male farmer, presented with itchy hyperkeratotic, scaly plaques with scarring and black dots on the lateral aspects of his left arm and dorsum of his left hand of 28 years duration. The case was clinically diagnosed as chromoblastomycosis. The second case, a 75-year-old farmer, presented with erythematous, crusted, scaly plaques on the dorsum of the left foot of 30 years duration. Initially, a clinical diagnosis of lupus vulgaris was made, but treatment with anti tuberculosis therapy showed no improvement. On the basis of histopathological examinations of skin biopsies and isolation of fungus on culture, both cases were diagnosed as chromoblastomycosis. To the best of our knowledge, these two cases are the first case reports of chromoblastomycosis from Nepal and are presented for their academic interest.

Epidermodysplasia verruciformis and generalized verrucosis: the same disease?

We report a patient with epidermodysplasia verruciformis (EV) who had severe generalized verrucous skin lesions for 50 years without any immunological abnormality. Microscopic examination showed two histopathological features, including seborrhoeic keratosis and common warts. The detected human papilloma virus (HPV) types were found to be HPV 3, 50, 5, and 76, using a degenerate PCR method. EV and generalized verrucosis are distinguished by slight differences in clinical symptoms or HPV types, so there should be no apparent differential points common to both diseases. Therefore, we propose that an abnormal susceptibility specific to HPV, which is the most characteristic feature in EV, should be regarded as a differential point in these two diseases.

Four non-endemic New Zealand cases of chromoblastomycosis.

The majority of cases of chromoblastomycosis are reported from tropical to subtropical countries; only one previous case being reported from New Zealand. Four non-endemic cases in Pacific Island patients are described. All of the New Zealand cases were caused by Fonsecaea pedrosoi. In the present report, one patient was successfully treated by excision of the lesion followed by skin grafting. Another was treated with 200 mg ketoconazole daily for 10 weeks with no obvious improvement. No follow-up on the treatment of this case nor of the remaining two patients is available. This disease must be included in the differential diagnosis in patients who present with chronic lesions affecting the skin and subcutaneous tissues.

Olive oil--contact sensitizer or irritant?

Adverse cutaneous reactions to topically applied olive oil are seldom reported, and positive patch tests to it are mostly regarded as allergic. To evaluate such "positive" patch test reactions, 77 female (mean age: 44 years) and 23 male eczema patients (mean age: 46 years) were prospectively patch tested with freshly prepared olive oil. Tests were performed openly (including ROAT) as well as using Al-tests and Finn Chambers on Scanpor. 5 patients (2 male) showed "positive" test reactions (all patients at the Al-test site, 3 at the Finn Chamber site, 1 with ROAT). In only 1 patient could the reaction be classified as probably allergic, in contrast to previous reports. In conclusion, olive oil is very weakly irritant in general, but bears relevant irritant capacity when applied under occlusive conditions. Therefore, olive oil appears to be less than suitable for the topical therapy of patients with venous insufficiency and associated eczema of the lower extremities.
