Macrocyst of the Breast / 50/F / (+) family hx of breast cancer
50/F; with ultrasound breasts, multiple cysts (8), left; 1° diagnosis: fibrocystic changes with 5-cm MACROCYST, left (98% certainty); recommended needle aspiration; would think it over first; came back the next week, aspirated 26 cc of serous fluid with complete disappearance of mass; advised monitoring; forewarned MAY RECUR; recurred 8 months after – aspirated 3 cc; recurred 2 years after – aspirated 7 cc. [then lost to follow-up]
MACROCYST – big cyst (containing fluid) palpable vs MICROCYST – small cyst, not palpable;
MACROCYST - BENIGN / NOT CANCER; MAY RECUR; WILL EVENTUALLY RESOLVED
Family history of breast cancer will not alter the diagnosis of MACROCYST as this was based on physical examination finding of cystic mass and ultrasound finding of cysts. Needle aspiration showed cyst also.
