In some cases the fungus invades the region between the toes and gives rise to intolerable itching and from secondary bacterial infections to a condition known as “Mango toe.”
It has seemed to me that when one has a coccal infection engrafted upon the fungus one the condition becomes what might be termed fulminating, so rapidly does the itch extend.
Treatment
When the process is markedly inflammatory mild applications are indicated, such as calamine lotion (30 grains each of calamine and zinc oxide with 5 or 10 drops of carbolic acid in 1 ounce of saturated solution of boric acid).
A 10% to 15% solution of sodium hyposulphite can, however, be used on the area even when markedly inflammatory.
Iodine applications are too irritating for the region of the scrotum.
An ointment of resorcin, 20 to 30 grains with 1 dram of sulphur to the ounce, may be tried. If chrysarobin be used it should be applied with greatest care as noted under tinea imbricata. Many advocate applications of solutions of salicylic acid in alcohol, 2% to 5%.
Manson’s dusting powder of equal parts of boric acid, zinc oxide and starch should be freely used.
