Trichodysplasia spinulosa is a rare polyomavirus-associated cutaneous eruption occurring in the setting of immunosuppression. Clinically it is characterised by multiple centrofacial folliculocentric papules with spinous protuberances. The histopathology is distinct and treatment with antiviral agents appears to be the most effective.

A 62-year-old Malaysian woman presented with a constellation of skin signs including alopecia, hyperpigmentation and nail dystrophy. On questioning, a history of diarrhoea, taste disturbance and weight loss was found. The onset of these changes coincided with the administration of thyroxine prescribed for a benign multinodular goitre. Hormonal investigations showed no abnormality and no underlying malignancy was found. Investigation of the diarrhoea showed a protein-losing enteropathy with generalized intestinal polyposis and non-specific histology. A diagnosis of Cronkhite-Canada syndrome was made. Treatment with prednisone and nutritional support has been partially effective.

Vesicular dermatitis due to contact with Coleoptera (bectles) is commou worldwide, although the condition has been infrequently described in Australia. We document the largest outbreak recognized so far in Australia with a conservative estimate of 250 eases, This occurred in central coastal Queensland over several weeks in late 1998. A survey of the medical practition ers in this district is presented, along with clinical and histopathological illustrations, Our research found that knowledge of the condition was limited even in this region where cases occur each year. This condition is an important differential diagnosis in acute blistering disorders.

A case of scleredema diabeticorum of Buschke associated with nuchal fibroma and organic solvent exposure is reported. The patient presented with a neck mass causing discomfort and restriction of movement. Histological examination showed this to be a nuchal fibroma. Additionally, there was widespread induration of the skin of his trunk which was asymptomatic. A biopsy showed features of scleredema. This is the first reported association of these two conditions, both of which show increased and thickened collagen bundles without significant fibroblast proliferation. They differ by the occurrence of mucin in scleredema, although this is not always demonstrable, particularly in late lesions. The possibility that nuchal fibroma is an end stage, localized form of scleredema is canvassed. The patient's medical history included insulin-dependent diabetes mellitus with complications of retinal vessel thrombosis and peripheral neuropathy. The patient also had significant past exposure to a wide variety of chemicals, including organic solvents.
