Plyushkin (Плю́шкин) was a character in the Nikolai Gogol's novel Dead Souls.
Today in Russia the name "Plyushkin" is semi-humorously applied to people who collect and amass various useless, broken, thrown-away things (such behaviour is typical for many old people).
Sometimes the terms "Plyushkin symptom" or "Plyushkin syndrome" are used to describe this. It is essentially the same thing as compulsive hoarding.
