To
determine the epidemiology of dermatophytosis in Palestinian patients,
detect changes in the etiological agents during the last three decades,
and to correlate between concomitant tinea pedis infections, and other
cutaneous lesions. 220
suspected dermatophytosis patients were involved in this study. In an
additional 38 cases, where consultation was prompted by tinea pedis, the
presence of other lesions of concomitant dermatophytosis was studied,
to further investigate the diagnosis. Clinical specimens were collected
and identification of dermatophyte species was based on gross and
microscopic morphology. Epidemiology
of tinea capitis has gone the most radical changes in Palestine in the
last three decades, with the zoophilic dermatophyte Microsporum canis
replacing Trichophyton violaceum, becoming the predominant causative
agent. During this study, 21.6% (38/176) patients with tinea pedis and
concomitant lesions caused by the same dermatophytes at sites distant
from the primary lesions in the foot were prospectively identified.
About 63.2% of patients with tinea pedis have a concomitant toenail
onychomycosis infection. The
epidemiology of dermatophytosis, especially tinea capitis, has gone the
most radical changes in Palestine in the last three decades, with M.
canis replacing T. violaceum, and becoming the predominant causative
agent of all cases of infections. The coexistence of tinea pedis with
other types of fungal skin infections is a frequent phenomenon; we
believe that the infected foot may be a site of primary infection. Thus,
the effective therapy for tinea pedis is essential to prevent spreading
the infection to other sites of the skin.
