A Case Report of a Glomangioma in an Unusual Location and Review of the Literature |Biomedgrid

Glomangioma or glomus tumors are rare neoplasms of the glomus body, which are located in the stratum reticularis of the dermis throughout the body. Its location on the elbow is unusual and presents a diagnostic challenge. It manifests clinically by a triad of pain, tenderness and cold hypersensitivity. We present a case of 75-year-old male who presented with a very painful nodule over the left elbow for the past 3 years. Dermoscopy showed an angiomatous nodule. After local excision, histopathology revealed sheets of epitheloid-like ovoid cells, disposing around dilated and congestive vascular structures without nuclear pleomorphism or mitotic activity. On immunohistochemistry, glomus cells were positive to smooth muscle actin, characteristic of a glomus tumor.
