Notice the presence of L&H cells, also known as "popcorn cells". (H&E) The characteristics of<unk>  differ from classical<unk>  lymphoma (cHL).<unk><unk>  (LP) ("popcorn") cells are present embedded in nodules consisting of B cells and other reactive cells (mainly reactive T cells). Reed-Sternberg and<unk>  (RSH) cells are rarely seen, and immunohistochemistry shows a different pattern on the malignant cells; RSH cells typically express CD15 and CD30, whereas LP cells lack expression of these markers, but express B cell markers like CD20, CD22, and CD79a and also express the common leukocyte antigen CD45, which is uncommon on RSH cells. The LP cells have scant cytoplasm and one folded or multilobated nuclei with prominent, mostly basophilic nucleoli. Expert pathology review of multiple morphologic and immunophenotypic features including the use of immunohistochemistry is essential. Tumors Tumors generally located in the peripheral lymph nodes which can be detected via PET scan and CT scan. Staging Ann Arbor staging is used to classify tumors and symptoms. Stage IV disease is very rare. Sex There is a male<unk> e of<unk>  diagnosis. B Symptoms B symptoms may be uncommon. Early Detection Diagnosis usually occurs at an early stage of disease progression.
