Generalized eruptive keratoacanthomas of Grzybowski
A 48-year-old man presented with a two-year history of a generalized, pruritic eruption that was associated with numerous, dome-shaped papules and nodulocystic lesions. Biopsy specimens have shown keratoacanthomas and a lichenoid dermatitis. Evaluation for malignant conditions has been negative. Owing to the constellation of findings, a diagnosis of generalized eruptive keratoacanthomas of Grzybowski associated with lichenoid dermatitis and acneiform lesions is favored. The patient is currently on a trial of acitretin.
