These are infections confined to the dermis, subcutaneous tissue or adjacent structures. infection may arise following the wounding of the skin and the introduction of vegetable matter. these mycoses are rare and confined mainly to tropical regions. they tend to be slow in onset and chronic in duration. an example is sporotrichosis caused by sporothrix schenckii. the fungus is dimorphic, being a mould that can convert to a yeast form at 37°c on rich laboratory media or in infection.
