Skeletal metastases were documented by CT and bone marrow biopsy, and high increased CA 15-3 level was recorded. This case report points to the potential risk of false-negative… (More)
We report focally intense F-FDG PET/CT rectal activity (SUVmax = 25) with a horseshoe distribution in an 81-year-old man with B-cell chronic lymphocytic leukemia and suspected Richter transformation. While imaging findings were typical for rectal adenocarcinoma, histology revealed Epstein-Barr virus-positive mucocutaneous ulcer.

Wagner-Meissner corpuscles are touch receptors that are located in dermal papillae and are usually absent in gastrointestinal mucosa. Wagner-Meissner-like corpuscles have been reported in association with benign neural neoplasm. A case of Wagner-Meissner-like corpuscles in endoscopically normal gastric mucosa biopsy of a 48-year-old woman is presented here.… (More)
