Gastrointestinal fibromatosis is a rare mesenchymal tumor. It has local invasive behaviour with low-metastatic potential. We present a 36-year-old female patient presented to Oncology Center, Mansoura University, Egypt, with accidentally discovered gastric mass by abdominal computed tomography (CT). The mass was adherent to the posterior wall of the gastric fundus, the tail of pancreas and encasing the splenic artery. The patient underwent partial gastrectomy, distal pancreatectomy and splenectomy. Pathological examination of the specimen showed bland spindle cell proliferation, with oval nuclei, scanty eosinophilic cytoplasm. There was no detected mitosis or necrosis or haemorrhage. Immunohistochemistry of tumor cells was positive with β-catenin and SMA, while Desmin, CD117, DOG-1 and S-100 were negative. The patient did not receive any adjuvant therapy. The patient underwent strict periodic follow-up every 3 months with abdominal CT for 6 months after surgery.

The ambient dose of radiation therapy and nuclear medicine units of Clinical Oncology Hospital, Menoufia University were investigated using thermoluminescence dosimeter MTS-700 and surveymeter (Inspector Radiation Alert). The maximum% difference between read out of both MTS-700 (TLD) and surveymeter did not exceed 6% and 8% for the two hospital units respectively. Values of the annual ambient dose received in both hospital units were found to be incompliant with radiation protection regulations. In addition, the extremity effective dose Hp (0.07) of staff in nuclear medicine unit was measured using wrist and finger techniques. Results indicate in-homogenies distribution of fingertips doses. Radiation doses received by the wrists and fingertips of radiopharmaceutical staff preparing 99m Tc syringe were observed to be higher by a factor of about 1.41 and 1.44 respectively than those for the administrating staff whom injecting patients by 99m Tc syringe, but also still in congruent with international radiation protection regulations.
