Sea-urchin granuloma – http://id.who.int/icd/entity/1213279530

Sea urchin granuloma is a chronic granulomatous skin disease caused by penetration of sea urchin spines which have not been removed from wounds after injury. The spines are composed of inorganic matter including calcium carbonate and silica which incite a foreign body reaction. The granulomata are typically small pink to blue papules and nodules which later turn brown and are located most commonly on the feet and ankles or on the hands.
