title: Malignant cylindroma in Brooke-Spiegler syndrome.
abstract: A 68-year-old female patient presented with a history of gradual appearance of multiple nodules situated predominantly on the scalp and neck, with a few nodules on the trunk. The nodules began to appear at the age of 30. Family history revealed that the patient's brother, son, father and grandmother had similar cutaneous lesions. The dominant histopathological pattern was that of a cylindroma. Features of both cylindroma and spiradenoma (spiradenocylindroma) were present within the same lesion in some biopsies. Most lesions on the scalp were skin-colored with a smooth surface. The largest tumors located on the neck were tender and ulcerated. Histopathologically, these tumors had the morphology of a high-grade malignant solid neoplasm with epithelioid features.
