[Grzybowski type eruptive keratoacanthomas and ectropion. A therapeutic problem]

Eruptive Grzybowski-type keratoacanthoma is a rare variant of multiple keratoacanthoma and is not accompanied by internal malignancies. Up to now only 16 cases of eruptive Grzybowski-type keratoacanthoma have been described in the literature. Eruptive and solitary keratoacanthomas cannot be distinguished histologically. The multiplicity of skin lesions may be due to a genetic background. Our patient presented with multiple eruptive keratoacanthomas, ectropion and a mask-like face. Conservative treatment, e.g. with etretinate, did not lead to any improvement of symptoms in this case. Therefore surgical therapy was recommended for the patient's ectropion.
