We report a cutaneous ulceration which occurred following a BCG revaccination. Observation. A 17 year old man, without previous history, presented a large and slow progressive ulceration of the left deltoid area following a fortuitous BCG revaccination. He did not complain of any other symptom. The swab culture from the exudate isolated Mycobacterium boviswhereasthedirectanalysisbyZiehlstainingwasnegative. The ulceration healed in four months with local and systemic treatment with isoniazid. Discussion. BCG vaccination side effects are largely described and can be either nonspecific, like with all vaccinations, or specific and due to the infection with Mycobacterium bovis. It can behave like an infectious agent or an immunogenic agent. The BCG revaccination complications are much less known because there are only few publications in the literature.
