Three cases of 'mechanic's hands' associated with interstitial pneumonia: possible involvement with foot lesions.
We describe three cases of the rare combination of lateral erythema and hyperkeratosis of the fingers that typify a condition known as 'Mechanic's Hands'. The first and the third cases were unusual in that the condition was associated with cutaneous involvement of the feet and interstitial pneumonia but not with myositis, or with only mild muscular involvement, while the second case was typical, being accompanied by myositis and detectable antibodies against histidyl transferase. We propose that Mechanic's Hands can occur in association with foot lesions and interstitial pneumonia, even if it is not accompanied by myositis.
