Lympangioma cavernosum in the abdominal cavity is a rare benign tumour. In most cases, such tumours are diagnosed in the oral cavity and neck. The aim of this paper is to present our clinical observations and review of existing literature to draw attention to this disease. A 25-year-old woman was admitted to our department for a symptomatic tumour in the lesser curvature of the stomach. The patient was first operated on as a three-year-old child because the tumour extended from the back wall of the stomach to the gastro-colonic ligament. The medical records showed that it was a benign tumour; however, no diagnosis was specified. No symptoms were observed for 22 years. Currently, the patient is admitted for epigastric pain. Abdominal computed tomography revealed an extensive mass located between the left segments of the liver and the lesser curvature of the stomach. The patient was operated on, and the tumour was completely removed. The patient's postoperative course was uneventful. Histopathological examination of the lymphangioma cavernosum was performed. Two months after the operation, the patient did not report any complaints.
