conjunctival habronemiasis
granulomatous lesions caused by invasion by Habronema spp. larvae occurring on the third eyelid, or the eyelid proper, or on the conjunctiva of the medial canthus.
cutaneous habronemiasis
is manifested by granulomatous lesions caused by the invasion of skin wounds or excoriations by the larvae of Habronema spp. and Draschia megastoma. See also swamp cancer. Called also summer sore, bursati, granular dermatitis and jack sores.
gastric habronemiasis
large granulomatous masses in the gastric mucosa caused by invasion by Draschia megastoma larvae. They are usually clinically silent unless perforation of the gastric wall occurs. The larvae of Habronema majus and H. muscae cause mild gastritis but without the formation of tumors.

Es preciso establecer los diferenciales de la enfermedad, debido a que el diagnostico clinico muestra ser aparentemente sencillo, a menudo es diagnosticado erroneamente como Habronemiasis cutanea, tejido de granulacion exuberante, granuloma piogeno y sarcoide equino, ya que se caracterizan por lesiones similares en forma general, sin embargo, la presencia de kunkers (masas necroticas caseificadas), trayectos fistulosos y secrecion filante fibrinosanguinolentas son inequivocas en la pythiosis [13, 17].
