Acute hemorrhagic rectal ulcer syndrome: Comparison with non-hemorrhagic rectal ulcer lower gastrointestinal bleeding.

Objective: The aim of this study was to describe the clinical characteristics of acute hemorrhagic rectal ulcer (AHRU) and to elucidate its predictive factors.

Methods: The medical records of patients with AHRU were retrospectively reviewed. Their baseline clinical characteristics were compared with those of patients with non-AHRU lower gastrointestinal bleeding to identify predictive factors for AHRU.

A Case of Metastatic Low-Grade Endometrial Stromal Sarcoma Treated with Letrozole after Ovarian Ablation by Radiotherapy.

A 50-year-old woman was admitted to our hospital due to multiple lung nodules detected incidentally on a chest X-ray.

For the first time in Korea, we experienced a case of ISCM arising from rectal cancer, where a 75-year-old man presented with an abruptly-developed left-foot drop and numbness in both legs.
