Dermato-venereological Quiz

An 82-year-old Chinese gentleman presented with a painless solitary nodule on his scalp. He noticed the nodule for a month, consulted a practitioner and was told that he had a sebaceous cyst. Recently the nodule became eroded. Physical examination showed an eroded scalp nodule, two centimeter in diameter, with a central crater. Friable material was found in the centre. A 19-year-old lady presented with multiple growths on the back of her thigh. They were there for a year and were asymptomatic. Physical examination found multiple small cystic papules, each about two to three centimeter in diameter, with a grayish-blue tinge at the back of her thigh.
