Occasionally only endometrial glands are present in cases of endometriosis. Hemosiderin-laden macrophages may be present also, but their solitary presence without endometrial glands or stroma does not confirm endometriosis. Sampson first applied the name “endometriosis” to ectopic endometrium in 1921 (Sampson 1921).\nAccess this chapter\nTax calculation will be finalised at checkout\nPurchases are for personal use only\nReferences\nBarbieri, R.
