RESUMEN
ABSTRACT: Although abnormal 68 Ga-PSMA uptake in the prostate and its metastases can be seen in a variety of diseases, it is rare to see in the testis. In these 2 cases, 68 Ga-PSMA PET/CT revealed unilateral 68 Ga-PSMA uptake in the testis of 2 patients. One of these patients was diagnosed with testis metastases from prostate cancer after an orchiectomy. The other patient was diagnosed with an orchitis. 68 Ga-PSMA uptake should be considered as an infection, as well as a malignancy in the initial differential diagnosis.

ABSTRACT: 68 Ga-prostate specific membrane antigen (PSMA) PET/CT scan for staging revealed increased 68 Ga-PSMA uptake in solar elastosis in a patient with prostate cancer. Solar elastosis is a degenerative condition of elastic tissue in the dermis caused by prolonged sun exposure. A few studies have demonstrated 68 Ga-PSMA uptake in cutaneous lesions. This case illustrates another instance of a benign cutaneous lesion accompanied by increased 68 Ga-PSMA uptake.
