ABSTRACT

Actinomycosis of the lung is rare and difficult to diagnose. Its good prognosis after medical treatment contrasts with the high frequency of surgical excision, due to the fact that pre-operative diagnosis is exceptional. Following a review of the recent bacteriological, radiological and therapeutic data available in the literature, 4 personal cases are presented. In all 4 cases actinomycosis was diagnosed post-operatively on the presence of yellow grains in the histological specimens. In 2 cases surgical excision proved impossible, but an almost complete radiological recovery could be obtained after prolonged treatment with co-trimoxazole. This shows how important it is to be aware of the disease, to improve its diagnostic approach and to remember its sensitivity to antibacterial agents, even in well organized forms.
