EXTENSIVE visceral actinomycosis has for many years been considered to be a severe disease with a uniformly poor, if not hopeless, prognosis.1 In recent years emphasis has been placed by some authors on the importance of adequate surgical measures in the alleviation of this disease.2 Others3 have emphasized the use of chemotherapeutic agents. Reports during the past few years of successful treatment in cases of actinomycosis of the abdominal or thoracic viscera far outnumber those reported in previous decades. Kolouch and Peltier,4 in reviewing the literature, summarized the reported cases according to type of treatment received (table).
Statistically, the percentage of patients listed as cured or improved is not wholly significant, for the numbers are small and the overlapping of treatments employed allow only a relative evaluation. Kolouch and Peltier pointed out, however, that significant trends are apparent, one of which is the decreasing mortality rate
