The ease here described is the fifth one of oriental sore which has been encountered in Ancon Hospital. As the pathogenic agent, epidemiology, histopathology and treatment of the previous cases have recently been described in detail,2 I wish here only to record the unique feature of the case under consideration.
REPORT OF CASE
The patient, E. N., a Panamanian farmer aged 35, is a resident of San Carlos, Los Santos Province, Panama. His present lesions are of three years' duration. He is married and has six children. His wife, children and acquaintances are free from similar lesions.Almost the entire length of the helix of the left ear is rather deeply ulcerated. The ulcer has the characteristic peripheral fossa and raised edges, and is entirely covered with a thick, hard, black crust. A similar condition, but to less extent, exists on the right ear and on the extensor. surfaces
