“…(4) Hemangiopericytoma: dilated blood vessels can be seen in both hemangiopericytoma and GGT, but the blood vessels of hemangiopericytoma are mostly antler-like. The surrounding cells are fusiform, CD34 is positive, and smooth muscle markers are negative [4,12]. (5) Lymphoma: it is difficult to distinguish lymphoma from GGT in frozen sections.…”

Gastric glomus tumors (GGTs) are rare mesenchymal tumors. Most glomus tumors occur in the distal parts of the extremities. Here, we retrospectively analyzed the features of GGTs from two institutions. The histologic and clinical findings of all GGT cases from 2009 to 2018 were reviewed. The most common location was the antrum, the mean age of patients was 49.3 years, and the mean tumor size was 2.1 cm. Microscopically, small, round cell nodules surrounded the expansion of blood vessels in a nest pattern. Immunohistochemical assays for vimentin and smooth muscle actin (SMA) were positive, and assays for H-caldesmon and calponin were partially positive. GGT is rare and easily misdiagnosed before operation. However, immunohistochemistry is useful for the differential diagnosis. The majority of GGTs are benign, and local surgery achieving complete resection is the most effective treatment method.

“…Biopsies from the lesion were positive for leiomyoma. Kapur et al had similar FNA biopsy results [19]. In addition, Lorber et al [6] reported that FNA biopsy in their case, suggested a well differentiated neuroendocrine tumor, possibly carcinoid.…”

Gastric glomus tumor: A case report

Gastric glomus tumors are rare mesenchymal tumors of the gastrointestinal tract. We describe a 72-year-old patient who presented with episodes of melena and was subsequently investigated for a tumor of the antrum of the stomach. Surgical resection revealed a 2 × 2 × 1.7 cm well circumscribed submucosal tumor, extending into the muscularis propria. The histopathologic examination of the specimen demonstrated a glomus tumor of the stomach. We discuss the preoperative investigation, the diagnostic problems and the surgical treatment of the patient with this rare submucosal lesion.

“…GT in visceral locations are very rare and mostly found in gastrointestinal tract, especially gastric antrum [3,4] and duodenum, although tumors in colon [5] , trachea [6] , bronchus [7] , lungs [8,9] , kidney [10,11] , urinary bladder [12] , ovaries [13] , liver [14,15] , breast [16] , bone [17] , skeletal muscle [18] and other organs were described. The incidence of gastric GT is 1% of GISTs [5] .…”

Glomus tumor is a rare benign mesenchymal tumor, mostly found in acral skin or superficial soft tissues, but it can occur in other locations. Glomus tumors in different locations share similar histological and immunohistochemical characteristics, although some aberrant features can be identified. We report a case of 41 year-old male with gastric glomus tumor, preoperatively diagnosed as CD117 negative gastrointestinal stromal tumor. Apart from the rare location, glomus tumor showed some other unusual features -peritumoral polytypic plasmacytosis and florid mesothelial hyperplasia. Although gastric glomus tumors are rare, they should be included in differential diagnosis of submucosal gastric tumors.
