Article Synopsis
- Lymphangiomas are rare benign tumors linked to the lymphatic system, with a notable case involving a 35-year-old woman who had a rapidly growing cystic mass in her axilla, diagnosed as cystic lymphangioma after imaging studies.
- The surgical procedure successfully identified and removed a single feeding lymphatic vessel using an indocyanine green (ICG) fluorescence imaging system, which helped in ensuring complete excision.
- The case suggests that prior pregnancy could have caused mechanical obstruction leading to the adult-onset lymphangioma, and highlights the effectiveness of ICG imaging for such surgeries.
The origin of the differences in the refractive index observed between normal and tumor tissues using terahertz spectroscopy has been described quantitatively. To estimate water content differences in tissues, we prepared fresh and paraffin-embedded samples from rats. An approximately 5% increase of water content in tumor tissues was calculated from terahertz time domain spectroscopy measurements compared to normal tissues.

The complex refractive index spectrum obtained by a reflection terahertz time-domain spectroscopy system can discriminate between normal and tumor tissues. Both the refractive index and absorption coefficient of tumor tissues are higher than those of normal tissues and can be attributed to the higher cell density and water content of the tumor region.

A 75-year-old man was admitted to our hospital with severe epigastric pain without past history of laparotomy and/or trauma. He was diagnosed with strangulation of the ileum by the findings of computed tomography, and the operation was performed.

Patients And Methods: Five hormone-responsive postmenopausal women who used AI as a first-line hormone therapy for advanced or metastatic breast cancer, but AI failed, received high-dose toremifene therapy(HD-TOR: 120mg/day)in our hospital.
