Cylindroma
Cylindroma is a benign skin tumor. They are seen together with spiradenomas and trichoepitheliomas. Spiradenocycylindromas showing the characteristics of cylindroma and spiradenoma are seen in the same mass of tumor which shows similar derivation of the tumor. Cylindroma are usually seen on the head and the neck in the form or solitary or multiple tumors. The solitary ones occur sporadically and are not inherited whereas the multiple tumors are seen to be inherited dominantly. The nodules grow and coalesce on the person’s scalp thus forming a turban like tumor. Malignant cylindroma is rarely seen. However, they may develop within solitary cylindromas. They can also follow multiple cylindroma.
