Recurrence of primary extramedullary plasmacytoma in breast both simulating primary breast carcinoma

“…It can occur in any organ as a solitary form of plasma cell neoplasm [2]. Although SEP can arise throughout the body, almost 90% of the cases arise in the head and neck areas, most commonly in the upper respiratory tract including the nasal cavity, para nasal sinuses, oropharynx, salivary glands and larynx [3-7].…”

Synchronous infiltrating ductal carcinoma and primary extramedullary plasmacytoma of the breast

“…It can occur in any organ as a solitary form of plasma cell neoplasm. [ 1 ] Some authors consider SEP to be unrelated to multiple myeloma. Although SEP can arise throughout the body, almost 80% to 90% of the cases arise in the head and neck areas.…”

“…Extramedullary plasmacytoma is described most frequently in the upper respiratory tract but it may also be found in the oral cavity, gastrointestinal tract, lung, lymph nodes, skin, and subcutaneous tissue [ 1 , 2 ]. Involvement of the breast is rare.…”
