Superficial lymphangitis with interface dermatitis occurring shortly after a minor injury: possible involvement of a bacterial infection and contact allergens.
BACKGROUND
Linear supralymphatic eruptions with epidermal involvement have rarely been reported.


OBJECTIVE
A search was made for apparent anatomical reasons and for external factors to explain the unique distribution pattern and clinical course in three cases in which the linear lesions occurred shortly after a minor injury.


METHODS
Efforts to search for its etiology include careful outlining of the localization, bacterial culture from the site of traumatic injury, patch tests, and skin biopsies.


RESULTS
Linear lesions developed along superficial lymphatic vessels and the presence of eczematous conditions around the injured sites and isolation of Staphylococcus aureus from the site were observed concomitantly. The histopathological findings showed interface dermatitis.


CONCLUSIONS
Our cases provide a unique example of the combined effects of a bacterial infection and contact allergens in the development of the linear supralymphatic eruptions.
