Reed-Sternberg cells (RSC) (Classical and variants)
Type of cell Characteristics
Classic
Reed-Sternberg cells (RSC) Include large size (20–50 micrometres), abundant, amphophilic, finely granular/homogeneous cytoplasm; two mirror-image nuclei (owl eyes) each with an eosinophilic nucleolus and a thick nuclear membrane (chromatin is distributed close to the nuclear membrane).
Variants
Hodgkin cell (Atypical mononuclear Reed-Sternberg cell) has the same characteristics as Reed-Sternberg cells (RSC), but is mononucleated.
Lacunar Reed-Sternberg cells Are large, with a single hyperlobulated nucleus, multiple, small nucleoli and eosinophilic cytoplasm which is retracted around the nucleus, creating an empty space ("lacunae").
Pleomorphic Reed-Sternberg cells Has multiple irregular nuclei.
"Popcorn" Reed-Sternberg cells (Lympho-histiocytic variant) is a small cell, with a very lobulated nucleus, small nucleoli.
"Mummy" Reed-Sternberg cells has a compact nucleus with no nucleolus and basophilic cytoplasm.
