Microscopic carcinoma of the breast--report of a case

Microscopic cancer is extremely rare even among "occult breast cancers". We treated a 70 year old woman with complaints of serosanguineous nipple discharge which yielded cytologically Class V cancer cells. Microdochectomy was performed and intraductal carcinoma was verified histologically in serially cut sections. Following a simple mastectomy, she has been well with no evidence of recurrence or metastasis, at this time.
