Micrometastatic Gastric Glomus Tumor Confirmed by Next-Generation Sequencing

Abstract

Glomus tumors are uncommon perivascular neoplasms.¹ Derived from the glomus bodies of the dermis involved in thermoregulation, glomus tumors are found most frequently in areas of the body rich in such glomus bodies, including the subungual areas of the digits and the distal extremities in general. Although they are most common in the superficial tissues, glomus tumors may occur in visceral organs, including the liver, lung, pancreas, and gastrointestinal and genitourinary tracts.² When glomus tumors do occur in the gastrointestinal tract, they are most often located in the stomach.³
