Description
Dermatophytosis - clinical aspects by David Grant. After a brief introduction to the fungi with definitions and classification there will be a series of illustrations demonstrating the variability of clinical signs. This variability allied to the relative rarity of the condition in the UK can lead to diagnostic difficulties. To help resolve these difficulties the differential diagnosis is outlined according to lesion types and this is followed by examples of the various diagnostic techniques available. This begins with the use of the Wood’s lamp (along with suggestions of how to maximise its usefulness). Next are examples of positive trichoscopy examination, the use of dermatophyte test medium, and further identification of species by colony morphology and microscopic conidia identification. Microsporum canis, in particular, is zoonotic and several illustrations of human lesions are shown and these can be useful in diagnosis. The webinar will conclude with a discussion of the topical and systemic products currently used in treatment with some information on environmental decontamination.
