title: Photoletter to the editor: Fibrous histiocytoma developing at the site of tuberculin skin test.
abstract: Benign fibrous histiocytomas of the skin sometimes extend into the deeper dermis with higher cellularity and show more aggressive clinical courses in comparison with typical dermatofibromas. They may occur either as a true neoplasm or in a reactive process. We describe a case of fibrous histiocytoma which was triggered by tuberculin skin test.
