Schwannoma of the Sigmoid Colon: A Rare Case.

Schwannoma is a type of peripheral nerve sheath tumor that is often found in the head and neck. Schwannomas in the digestive system, particularly the colon and rectum, are exceptionally rare, and they are mostly non-malignant and asymptomatic although sometimes patients can present with symptoms similar to those observed in patients with other gastrointestinal tumors like abdominal pain, fullness, nausea, vomiting, and change in bowel habits. For diagnosis and treatment, surgical resection along with biopsy is the gold standard. In this paper, we describe a rare case of sigmoid schwannoma that was successfully treated in our department by surgical resection.

Leukemoid Reaction With Severe Diabetic Ketoacidosis.

A leukemoid reaction is a rare condition characterized by an elevation in white blood cell count exceeding 50,000 cells/µL in response to severe medical conditions, which can mimic the presentation of chronic myeloid leukemia (CML). Distinguishing between leukemoid reaction and CML depends on a thorough clinical history and comprehensive laboratory evaluation. We present a case of leukemoid reaction associated with severe diabetic ketoacidosis, where the patient's white blood cell count returned to the normal range after the correction of hyperglycemia and electrolyte imbalances.
