Comparative Study Controlled Clinical TrialComparison of different injection sites of radionuclide for sentinel lymph node detection in breast cancer: single institution experience.
There are still ongoing controversies about several aspects of lymphatic mapping and sentinel lymph node biopsy for breast cancer, including injection site of radioisotope and blue dye. This study aims to evaluate the success rate of different radiocolloid injection techniques in the detection of sentinel lymph nodes (SLN) in early breast cancer. ⋯ The success rate was superior with intradermal periareolar injection compared with PT and SD injection to visualize the axillary SLN. However, PT deep injection combined with ID-PA injections may be more favorable to demonstrate the primary internal mammary (IM) lymphatic drainage.

Case ReportsIncreased F-18 FDG uptake on positron emission tomography/computed tomography imaging caused by plantar fibromatosis.
We detail the history and evaluation of a 68-year-old man who had head-to-toe PET/CT scanning that showed a focal area of increased FDG uptake in the left medial foot. This was thought to be recurrence of his melanoma. The patient was asymptomatic. ⋯ On biopsy, the foot lesion was diagnosed as plantar fibromatosis. Plantar fibromatosis is a benign fibroblastic condition, which can be indistinguishable from malignancy in head-to-toe PET/CT scans. Awareness of their potential appearance on PET and PET/CT will aid in the appropriate staging of oncology patients.
