[2 cases of melanomatous erysipelas--differential diagnosis and terminology].

Erysipelas carcinomatosum can be differentiated on the one hand from other special forms of cutaneous metastasis, such as carcinoma teleangiectaticum, carcinoma en cuirasse or carcinoma eburné and on the other from secondary tumour-specific or non-tumour-specific erythematous lesions. Two cases of erysipelas melanomatosum and transitional forms of the different types of cutaneous metastasis will be discussed with special reference to melanoma.
