[Hemothorax associated with von Recklinghausen's disease; report of a case]

We report a case of hemothorax in a patient with von Recklinghausen's disease. A 40-year-old male was transfered to our hospital because of sudden severe right back pain. Chest computed tomography (CT) scan showed right hemothorax that ruptured intercostal artery. He underwent selective angiography that demonstrated a pseud aneurhysm in the 10th intercostals artery and treated with endovascular coil embolization. We conducted surgical right thoracic drainage on post embolization day 7. In the 2 year since his embolization and operation, there has been no recurrence of hemothorax.

Colorectal cancer after pelvic irradiation: case reports

Four patients with colorectal cancer after pelvic irradiation for gynaecological malignancies are reported. The interval between irradiation and the diagnosis of colorectal cancer was 15-28 years. Histological findings of radiation proctocolitis adjacent to the cancer were observed in all specimens. Ki-67 immunohistologic staining showed high cell proliferation activity in the irradiated mucosa of a recently removed specimen. Although irradiation has not been proved to induce colorectal cancer, considerable circumstantial evidence supports this belief. Awareness of this potential long-term complication is important when planing the follow-up of patients subjected to pelvic radiotherapy.
