Mould identification: a virtual self assessment
An otherwise healthy 25 year old male presented with an ulcerated, erythematous plaque on a tattooed area of the left forearm. This lesion had begun 15 months previously as a papule, which he thought, resulted from a scratch received whilst installing insulation. Slow enlargement had occurred despite several courses of antibiotics and two attempts at excision. Culture from a skin biopsy grew the fungus shown below.
