It affects females slightly more than males and has a median age of onset at ~28 years. It is composed of large tumor nodules with lacunar Reed–Sternberg cell (RS cells) surrounded by fibrotic collagen bands. The British National Lymphoma Investigation further categorized NSHL based upon Reed-Sternberg cells into 'nodular sclerosis type I' (NS I) and 'nodular sclerosis type II' (NS II), with the first subtype responding better to treatment.
