Abstract
- Disseminated superficial actinic porokeratosis, a variant of porokeratosis, is an uncommon, hereditary or acquired keratinization disorder. It is characterized histologically by cornoid lamella and clinically by central atrophy with elevated borders. Porokeratosis lesions may be triggered by UV light exposure, infection, hematopoietic malignancies, or immunosuppression, but are rarely reported associated with malignancies of visceral organs. We herein report an unusual case of a patient with colon cancer who noted sudden exacerbation of a previously unrecognized disseminated superficial actinic porokeratosis lesion after being treated with chemotherapy.
