geotrichosis /jē′ōtrikō″sis/ [Gk, ge, earth, thrix, hair, osis, condition] , a condition associated with a rare fungus Geotrichum candidum, which can cause oral, bronchial, pharyngeal, and intestinal disorders. G. candidum is normally found in healthy individuals, soil, and dairy products and is not necessarily pathogenic. Geotrichosis most commonly occurs in immunosuppressed individuals with diabetes. Bronchopulmonary complications associated with this disorder may produce a cough with thick, bloody sputum. Geotrichosis has been associated with allergic asthmatic reactions similar to allergic aspergillosis and a type of intestinal disorder characterized by abdominal pain, diarrhea, and rectal bleeding. Oral lesions that may occur with this disorder are commonly treated with a solution of gentian violet; associated abdominal lesions are treated with the oral administration of gentian violet capsules. Associated pulmonary lesions are treated with the oral administration of potassium iodide.
