For cases diagnosed 1998-2003:
Code the EOD-Size of Primary tumor field to 998 [Diffuse; widespread; 3/4 or more of breast; inflammatory carcinoma] for all inflammatory breast carcinomas.
These cases have a worse prognosis because of the dermal lymphatic invasion. Half of the inflammatory breast carcinomas will have no palpable mass.
