Polymorphism of Wangiella dermatitidis

  • Philip A. Geis
  • Charles W. Jacobs


Wangiella dermatitidis exhibits a polymorphism consisting of three well-defined morphologies, together with various forms characteristic of transitions among them (Figure 1). The organism may exist as moniliform or true hyphae, characterized by apical growth and production of blastoconidia. Alternatively, it may be found as unicellular budding yeasts, characterized by intermittent polar growth associated with bud formation and secondary isotropic (spherical) growth. Third, it may form enlarged, thick-walled cells, characterized by isotropic growth and, eventually, by the formation of internal septa. This third morphology, the multicellular form, resembles the sclerotic bodies produced by etiological agents of chromoblastomycosis (Rippon, 1982).
