ABSTRACT

Mucinous prostate adenocarcinoma represents <0.1% of prostate cancers. To our knowledge, no previous report has described the 68 Ga-PSMA-PET characteristics of this entity at the primary site. We present a case of a fit 85-year-old with PSA 0.55 ng/mL and ISUP grade 4 acinar adenocarcinoma with mucinous features on biopsy. 68 Ga-PSMA-PET revealed an intensely avid primary lesion in the right prostate (SUVmax 10.9), concordant with biopsy findings and encompassing both the PI-RADS 5 lesion identified on MRI and a PI-RADS 1 lesion that presumably represented the mucinous component. The patient was treated with definitive radiotherapy to the prostate and lymph nodes with 6 months of androgen deprivation therapy.
