Steatoma, or sebaceous cyst, is due to an overproduction of sebum by one or more sebaceous glands while the usual outlet is closed. When this collection remains in situ for years, the peripheral pressure destroys the epithelial lining of the cyst and the sebum may undergo calcareous degeneration.
A few isolated steatomas scattered in various parts of the body are a frequent occurrence. Occasionally one sees large numbers of the pinhead-sized or the pea-sized lesions. The "multiple follicular cutaneous cysts of Bosellini, or steatoma multiplex of Pringle or sebocystomatosis of Günther'' were studied extensively by Ormsby and Finnerud,1 Lisi,2 Fraccari,3 Mount4 and others.
Instances of lesions of large size grouped in large quantities in one region of the body are rare. Similar lesions with extensive calcification seem to be extremely rare.
