Disseminated granuloma annulare following erythema multiforme minor

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 4 2000
Zeev Abraham
SUMMARY A 44-year-old woman presented with erythema multiforme minor followed by disseminated granuloma annulare 4 weeks later. The patient was not taking any medication and had no history of herpes simplex infection. Involvement of a delayed-type hypersensitivity reaction in the pathogenesis of these two well known disorders, as suggested by immunological investigations, may explain their concurrence in our patient. The substitution of the erythema multiforme minor lesions by an eruption of disseminated granuloma annulare at the same sites suggests the possibility of a Koebner phenomenon or an isotopic response.

Koebner phenomenon due to scratch test in scleromyxoedema

BRITISH JOURNAL OF DERMATOLOGY, Issue 2 2001
B.K. Durani
The Koebner phenomenon or isomorphic response was originally described in psoriasis and has subsequently been observed in various other diseases. We report a patient with isomorphic response in scleromyxoedema, a variant of papular mucinosis with diffuse infiltration of the skin. The Koebner phenomenon was due to a scratch test performed 4 weeks before the appearance of streaky, lichenoid infiltrations on the forearms. [source]

Development of lichen planus and psoriasis on lesions of vitiligo vulgaris

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 3 2006
H. Ujiie
Summary This paper reports a unique case of coexistence of vitiligo vulgaris, lichen planus and psoriasis vulgaris in a 53-year-old man. Five years after the onset of vitiligo, lichen planus developed on his lower lip. Another 4 years after the onset of lichen planus, he also exhibited psoriasis on his upper arms and trunk. Both the lichen planus and psoriasis occurred on lesions of the preceding vitiligo vulgaris. We discuss potential mechanisms for association of these three dermatoses, including Koebner phenomenon and photodamage. [source]
