54 year old woman complains of dry cracked heels that worsen in the fall and winter. The condition has be recurrent over the past 3-5 years. Her mother had the same problem. She complains that her heels actually catch on her sox and stockings and tear and bleed.
What is your diagnosis?
This disorder was first described by Haxthausen in 1934. Hyperkeratosis begins
over pressure points on the heels in women over the age of 45 years. There is
no preceding history of skin disorders, including eczema or psoriasis. As the
hyperkeratosis extends, fissures form and make walking painful. Obesity and dry
winter climates aggravate the symptoms, as can wearing backless shoes, e.g. sandals.
If present, involvement of the hands is much milder and more discrete. Deschamps
et al. investigated 10 patients with keratoderma climactericum, measuring sex
hormone levels and serum vitamin A levels as well as performing fungal scrapings
and patch tests, all of which were normal or negative. Others have reported similar
changes in young women following oophorectomy, which responded to estrogen replacement.
In my experience, the condition is seen more frequently during the drier parts of the year (fall and winter). In fact, my one of my previous partners used to call this "Minnesota Winter Foot." There seems to be some debate whether this is a true keratoderma or just an extreme case of xerosis of the foot. I see it in men and women and in almost all ages in winter in Minnesota. Nevertheless, I find the simple treatment program outlined below tends to work very well for management and resolution.
Apply Eucerin Plus cream (it has to be this exact formulation of the Eucerin products - others do not work as well). I have my patients soak their feet in warm water for three-five minutes, pat dry, apply the Eucerin Plus cream liberally to their heels, and apply cotton socks for occlusion therapy overnight. I also have them put another coat on in the morning after bathing or showering. I find for the vast majority of patients, this tends to improve or even eliminate the condition to the patient's satisfaction in approximately one week. I like Eucerin Plus cream because the Plus indicates that it has both ammonium lactate for extra moisturization and urea for additional moisturization and loosening of dry skin and scale.
