Familial eruptive dermatofibromas in atopic dermatitis.

Multiple eruptive dermatofibromas (MEDF) are rare and their aetiology is unknown. More than half of the patients with MEDF have underlying diseases, and more than 80% of the underlying diseases are immune mediated. Familial cases suggesting a genetic cause have also been reported. We report a case of familial eruptive dermatofibromas associated with atopic dermatitis, possibly caused by both hereditary factors and compromised immunity.
