Several necrotic skin nodules are present on this patient. They are partly ulcerated and are found on the right side of his neck. The surrounding skin shows a heavy reddening. The causative agent is a dimorphic fungus ocurring in the tissue as a relatively big yeast cell and may reach a diameter up to 23 µ. This deep mycosis occurs by inhalation with primary infection in the lungs as in many other deep mycoses.
