Ulcerative sarcoidosis: An atypical cause of leg ulcers.

We present the case of an 83-year-old woman with leg ulcers who was diagnosed with sarcoidosis. This case highlights the importance for clinicians to consider ulcerative sarcoidosis when encountering patients with leg ulcers along with hilar adenopathy, uveitis, elevated serum angiotensin-converting enzyme, and histopathological findings of epithelioid cell granulomas.

Crowned dens syndrome: A case series of 72 patients at eight teaching hospitals in Japan.

Background: Crowned dens syndrome (CDS) is characterized by calcification around the odontoid process, accompanied by neck pain. Although CDS is supposedly rare, we regularly diagnose and manage this condition, indicating a perception gap between previous studies and our experience. The purpose of this study was to determine the annual incidence of CDS, time to diagnosis in CDS, as well as the features of CDS.

A case of superior mesenteric artery syndrome characterized by deep forward bending posture in a cross-legged position on the floor.

A 17-year-old healthy male presents with severe epicardial pain and frequent vomiting 1 h after lunch, preferring to sit cross-legged on a stretcher with a deep forward bending posture along with difficulty lying down. SMA syndrome should be considered in the differential diagnosis of patients demonstrating such posture.

Inclusion body myositis in an older patient following a fall.

After experiencing a fall, an 82-year-old woman developed progressive loss of lower limb strength and was diagnosed with inclusion body myositis. Although falls and muscle weakness are often regarded as consequences of aging, inclusion body myositis should be considered in a patient with a history of multiple falls.

A case of angle-closure glaucoma caused by spontaneous lens dislocation.

Spontaneous lens dislocation without genetic factors is rare. In this case, spontaneous lens dislocation occurred without an apparent trigger and resulted in secondary angle-closure glaucoma. A head computed tomography (CT) scan showed lens dislocation.

Accessory liver lobe in the right thoracic cavity.

A healthy 42-year-old man presented to the hospital because of chest radiography performed during a medical checkup revealed a tumor. Contrast-enhanced computed tomography showed a tumor of 5 cm diameter just above the right diaphragm with blood flow from the portal vein. The patient was diagnosed with accessory liver lobe (ALL).

A case of diabetic ketoacidosis with hemorrhagic gastric ulcer.

This is a case of diabetic ketoacidosis with hemorrhagic gastric ulcer. Mortality rates increase when DKA is complicated with upper gastrointestinal bleeding, so it is important to consider this possibility.

Small bowel obstruction of barium for gastric cancer screening.

We report a case of small bowel obstruction without perforation and peritonitis caused by inspissated barium sulfate for gastric cancer screening and surgically treated 26 hours after the onset of abdominal pain.
