症例は73歳男性で, テレビを見ていたとき突然テレビの画面の色が白黒になった.その後も色彩が判断できず, 視野に映るものは白黒の濃淡で識別していた.相貌失認, 地誌的失見当, 着衣失行等は認めず, 視力は保たれていたが, 軽度の右同名半盲を認めた。色覚検査では以下の如くであった.物体の識別, 認知はすべて白と黒の濃淡でなされるため明度の配列は正確であった.色の命名は黒と白は可能で, 赤は茶色, 黄色は白ということが多く, 他の色は白と黒の濃淡でのみ表現した.頭部MRIでは, 両側後頭葉底面に脳回に沿った出血性梗塞を認め大脳性色覚障害の病巣を考える上で示唆に富む症例と思われた.

Olmesartan has recently been reported as a cause of drug-induced enteropathy characterized by chronic diarrhoea and duodenal mucosal atrophy demonstrating sprue-like enteropathy. 82-year-old, male presented to our hospital because of chronic severe watery diarrhea without abdominal pain or fever. Blood examination showed mild anemia (Hb 11.2 mg/dl). Abdominal contrast-enhanced computed tomography showed mucosal edema in the large intestine. Esophagogastroduodenoscopy showed no villous atrophy in the duodenum with the possibility of pyloric gastrectomy, however, colonoscopy showed villous flattering in the terminal ileum and edematous changes in sigmoid colon. Histopathologic examination in biopsy samples from the terminal ileum and sigmoid colon showed interstitial lymphocytic infiltration. He was treated with olmesartan for hypertension at least two years before the onset of symptoms. In addition, watery diarrhea improved soon after discontinuation of olmesartan. Therefore, he was diagnosed as olmesartan-induced enteropathy. Its pathogenesis remains unclear; however, olmesartan-induced enteropathy must be included in the differential diagnosis for patients with chronic diarrhea after the intake of olmesartan.

A 60-oyear-oold male visited a clinic because of gastric discomfort. This symptom was temporarily improved by a proton pump inhibitor, but it was worsened by discontinuation of the drug. He was referred to our hospital. Esophagogastroduodenoscopy showed an elevated lesion with multiple whitish small granular protrusions in the duodenal second portion, occupying two thirds of the circumference. The lesion was diagnosed to be a follicular lymphoma by histopathological examination including immunostaining of the biopsy specimens. He was admitted to our hospital. Abdominal CT scan showed no lymph node metastasis. Capsule endoscopy of the small intestine showed lymphoid follicles in the distal ileum in addition to the duodenal lesion. Bone marrow aspiration showed no invasion of lymphoma cells. This case was diagnosed as stage I according to the Lugano international conference classification. He underwent monotherapy using rituximab four times. However, the lesion did not respond. Therefore, radiotherapy was added which induced regression of the duodenal lesion. Follow-oup capsule endoscopy did not show any lesion in the distal ileum. As long-term outcome after treatment for duodenal follicular lymphoma is not known, strict observation is considered to be necessary.
