Dermatite érysipéloïde des membres inférieurs révélant un aspergillome du sinus maxillaire

The absence of relapse following treatment of the focus of aspergillosis forms a major argument in favour of a causal relationship between the erysipeloid dermatitis and the sinus mycotic infection. The hypothesis of a septic embologenic mechanism within the sinus was abandoned in favour of a mechanism similar to streptococcal nodular erythema, seen in diseases involving immune complexes, possibly caused by allergy to Aspergillus proteins. This case history demonstrates the existence of satellite skin signs of Aspergillus infection indicative of neither primary nor secondary aspergillosis.
