RESUMO
ABSTRACT: 131 I has been used effectively over the years in both diagnosis and therapy of differentiated thyroid cancer (DTC). Although whole-body scan with 131 I is a highly sensitive tool for detecting normal thyroid tissue and metastasis of DTC, it is not specific; therefore, false-positive images can be seen in clinical practice, and their recognition is critical for correct management. Evaluation of false-positive uptake is important because it may be confused with metastatic involvement. Here, we present a rare false-positive result of whole-body scan in a patient with DTC. To our knowledge, it is the first report on 131 I uptake of conjunctival concretions.

ABSTRACT: Although distant cutaneous metastasis is an uncommon presentation of prostate cancer, it remains an important diagnostic consideration as an advanced disease and a poor prognosis. Herein we present a rare case of prostate cancer patient whose multiple cutaneous metastases were treated with 177Lu-PSMA-617 radioligand treatment. To our knowledge, it is the first report in which a complete response was seen with 68Ga-PSMA PET/CT scan after 177Lu-PSMA-617 radioligand treatment.
