plasmacytoma CD138 and CD79a markers that were highly positive. No
atypical plasma cells were found in bone marrow biopsy. A diagnose
was changed to plasmacytoma of the small pelvis, os pubis and
inguinal lymph nodes. Before PET scan and chemotherapy patient was
tested positive on COVID-19, the treatment had been postponed.Keywords: extramedullary plasmacytoma, multiple myeloma. Primary EP is rare clinical entry.
