    ### Instruction:
    What is (are) Dermal eccrine cylindroma ?
    ### Response:
    Cylindromas are non-cancerous (benign) tumors that develop from the skin. They most commonly occur on the head and neck and rarely become cancerous (malignant).  An individual can develop one or many cylindromas; if a person develops only one, the cylindroma likely occurred by chance and typically is not inherited.
