IntroductionGastric tuberculosis is rarely seen in clinical practice, which occurs mostly secondary to lung tuberculosis, intestinal tuberculosis, and other common tuberculosis. Gastric tuberculosis rarely presents as a single microscopic superficial erosion. We recently diagnosed such a case, hence reporting it herein.Patient ConcernsA 40-year-old female patient was admitted with a chief complaint of painful enlarged cervical lymph nodes. She had no other symptoms or any previous history of remarkable diseases.DiagnosisPhysical examination found multiple enlarged cervical lymph nodes. Computer tomography revealed multiple circular well-defined soft tissue masses in the bilateral carotid sheath spaces. A cervical lymph node biopsy showed caseous necrosis with infiltration of neutrophils and lymphocytes, and most importantly, mycobacteria through staining for acid fast bacilli. Routine gastroscopy showed a 0.5 cm × 0.5 cm well-defined erosion on the large curvature of the gastric body. Gastric biopsy revealed chronic granulomatous inflammation with mycobacteria through staining for acid fast bacilli. The patient was diagnosed as having cervical lymph node tuberculosis and gastric tuberculosis.Interventions And OutcomesShe received 6 months of standard anti-tuberculosis therapy. The enlarged cervical lymph nodes shrank in size and the pain was relieved.ConclusionsGastroscopy should be performed to look for gastric tuberculosis if the patient presents primary tuberculosis in other organs/tissues such as cervical lymph nodes. If any small erosion is found, a biopsy is justified for checking the possibility of gastric tuberculosis.Copyright © 2022 the Author(s). Published by Wolters Kluwer Health, Inc.
