We report on a single case of a lichen planus like contact dermatitis caused by colour developers. We emphasize similarities to lichen planus with regard to clinical, histopathological and immunohistological aspects.
Prostatic carcinoma accounts for about 1% of all cancers that metastasize to the skin. The regions most frequently involved are the genital region, the head and the trunk. Clinically the lesions present as nodules; less often diffuse infiltrates, red macules and papules or tumors of an angiomatous appearance occur. Histopathological examination of skin biopsy specimens can reveal gland-like, epithelial or anaplastic differentiation of tumor cells. Prostatic origin can be proven by the immunohistological demonstration of acid prostatic phosphatase or prostatic specific antigen in paraffin-embedded specimens taken for routine histological examination.
Tick bite fever (boutonneuse fever) is endemic in India, Africa and especially the Mediterranean countries. It is occasionally "imported" into central European countries by tourists. The exanthematic disease is caused by infection with Rickettsia conori, which is usually transmitted by the brown dog tick. A typical primary lesion at the site of the tick's bite is an important diagnostic hint. The treatment of choice are tetracyclines.
The allergic contact dermatitis usually shows eczematous skin lesions. In few cases however pustular reactions can be observed. They are often caused by sensitization to metals and halogens. Herein we report a case occurring as pustulosis palmaris, that has been identified as an occupational allergic contact dermatitis to black rubber.
