Twenty cases of blastomycosis have been confirmed in the RSA, 9 of which are presented for the first time. Patients came from all four provinces and the mean age was 40 years. Six cases were diagnosed between 1985 and 1987. Differences between strains of Blastomyces dermatitidis isolated in the RSA and in North America include morphological and cultural characteristics, mycelial-yeast conversion, antigenic structure, and compatibility in cross-mating experiments. The diagnosis of this disease can be made by direct examination of unstained specimens, by histological examination or by culture of the organism. Culture should be attempted in all cases for confirmation of microscopic findings.

The known African cases of blastomycosis to 1987 are presented, including thirteen previously undescribed cases. This brings to 81 the total number of cases known to have occurred in Africa. The question of whether the disease in Africa is the same in all respects as that in North America is addressed; the age and sex distributions of patients are similar. Minor differences in the clinical features relate particularly to the type of skin lesion, the more frequent bone involvement and the less frequent central nervous system involvement in the African patient. Little is known about the epidemiology of blastomycosis in Africa; one noteworthy feature is the apparent absence of the disease in dogs. Isolates of Blastomyces dermatitidis from the two continents, although closely related, differ in some respects.

The osteophilic red grain mycetoma due to Actinomadura pelletieri is rare in southern Africa. This report describes an elderly patient with extensive bone involvement in which lymphatic spread to the inguinal lymph nodes had occurred. The diagnosis and management are discussed.
