{Reference Type}: Case Reports {Title}: Mammary analogue secretory carcinoma presenting as a cystic parotid mass. {Author}: Gupta K;Patwa HS;Niehaus AG;Filho GOF;Lack CM; {Journal}: Radiol Case Rep {Volume}: 14 {Issue}: 9 {Year}: Sep 2019 暂无{DOI}: 10.1016/j.radcr.2019.06.019 {Abstract}: We present a case of a 63-year-old male with an 8-year history of a left-sided cystic facial mass which recurred despite multiple drainage procedures. Imaging findings showed a cystic mass in the left parotid gland and it was surgically resected. Pathology confirmed it to represent a mammary analogue secretory carcinoma, a relatively newly described entity. This case illustrates that mammary analogue secretory carcinoma can masquerade as a cyst within the parotid gland.
