+Cause.+ The exciting cause of helomata is intermittent pressure combined with friction; while among the predisposing causes it is only necessary to mention the slavish adherence to fashion which lends all of us to wear stiff leather shoes, the contour of which bears little or no relation to the natural shape of the anterior portion of the foot. The pressure of the ill-fitting boot upon the toes, or, more strictly speaking, the pressure of the toes against the unyielding leather, in walking, soon occasions hypertrophy of the horny layer at the point of irritation, and in time a dense, conical, pea-sized or larger mass is formed. The apex of the cone presses downward on the sensitive papillae and causes the painful sensation which suggests a visit to the chiropodist. Helomata are named according to characteristics which mark them. When the growth is indurated it is called heloma durum; when soft, heloma molle; when of the millet seed variety, heloma miliare; when blood vessels are numerous, heloma vasculare. Each of these varieties requires a different method of treatment. Helomata are most frequently found on the outer surface of the little toes, but may occur upon the sole of the foot and even upon the palm, or plantar surface of the foot. Between the toes they often form from pressure of the opposing digits, caused by narrow shoes, and in this location they are softer and usually present a whitish, macerated surface. +The Prophylatic Treatment+ consists in wearing a broad-toed, though not necessarily a square-toed shoe. If shoes were made fan-shaped, like the imprint of a bare-foot in the sand, instead of having the greatest width across the ball of the foot, they might look strange at first, but they would be comfortable for all time. Those then who care more for comfort than for style, as most of us falsely profess to do, would have both cornless and comely feet. +The Palliative Treatment+ of helomata consists of first softening the dense, hard, horny tissue, when it will exfoliate spontaneously, or be readily scraped away. This projecting callous portion of the heloma may be removed by cutting or scraping till, as nearly as may be, the surface is level with the plane of the adjacent skin. In the soft variety found between the toes, or in the vascular ones, located in the arch on the inner border of the foot, where the skin is thin, no thick covering will be encountered. A line or groove will be observed marking the circumference of any variety of heloma, and it is in this line that the operative attack must be made. Helomata of the miliary variety, usually appear on the sole of the foot and are, as a rule, as numerous as they are small. The preferable treatment is to use a sharp, pointed knife in removing each one of the “seeds” separately.
