Bilateral ruptured isolated internal iliac artery aneurysms —Report of a case and review of the literature

We present herein, a rare case of a 78 year old man who experienced rupture of an isolated internal iliac artery aneurysm on 2 separate occasions. He underwent successful embolization with ligation of the right aneurysm at our institution, where only 2 such cases have ever been seen. Embolization with ligation proved very effective in clotting the intraaneurysmal blood in this case and would appear to be the treatment of choice for very large aneurysms. A review of the English and Japanese literature follows this case report.

Single primary lung cancer consisting of three cancer cell types (small cell carcinoma, adenocarcinoma, and squamous cell carcinoma) in which each had metastasized to different lymph nodes

We report a case of a 70-year-old male smoker with a single primary tumor 2.5 x 3.0 cm in size in the right lung lower lobe. A transbronchial lung biopsy revealed squamous cell carcinoma of the lung. We performed right lower lobectomy with lymph node dissection (ND2a). The resected specimen consisted of three different cell types; small cell carcinoma, adenocarcinoma and squamous cell carcinoma (in a ratio of 70: 20: 10). Each cancer cell types had metastasized to different lymph nodes. The final diagnosis was a combined small cell carcinoma in the lung. Combined small cell carcinoma is uncommon, but is nevertheless a well-described diagnostic category in lung cancers.
