[Findings on dermatomycoses observed at the Dermatologic Clinic, University of Pavia. A third pathology caused by Trichophyton rubrum].

From 1974 to 1988 T. rubrum have been isolated in 304 cases (27.8% of dermatophytes) in the Department of Dermatology in Pavia and it is the second most frequent fungus after M. canis. Males are more frequently affected (61.1%) than females (38.9%). A single localization was found in 82.2% of the cases and two or more types of "Tineae" only in 17.8%. The age-group 31-40 is more frequently affected (29%). The most frequent dermatophytosis caused by T. rubrum was Tinea pedis (33.9%) while Tinea capitis resulted a very rare localization (2.1%). An increase of T. rubrum infections is noted particularly in the last years.
