Glomic Tumour of the Stomach: A Rare Cause of Anaemia

Glomus tumour is a rare benign mesenchymal neoplasm usually located in the dermis and subcutis, and most commonly found in the extremities. Glomus tumour in the gastrointestinal system is rare and its symptoms unspecific. The diagnosis of gastric glomus tumour is challenging due to the lack of specific findings on imaging and blood analysis, and so is usually based on histology and immunochemistry. We describe the case of a 22-year-old man admitted for pallor and anaemia, the diagnostic path, treatment and follow-up. The present case suggests that this rare entity should be considered in the differential diagnosis of gastric lesions. LEARNING POINTS: Glomus tumour is a rare benign mesenchymal neoplasm most commonly found in the extremities. Gastric glomus tumour (GGT) is rare and its symptoms unspecific. The diagnosis of GGT relies on histology and immunohistochemistry as imaging lacks accuracy. Treatment is usually surgical but follow-up should be considered due to its malignant potential.
