Question:

EOD-Size of Primary Tumor--Breast: If the patient has inflammatory carcinoma of the breast, is the tumor size coded as 998 even though we have a tumor size?

Discussion:

Answer:

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.
