Pulmonary Glomus Tumor

Abstract

Glomus tumor, also known as glomangioma, is a neoplasm derived from cells of the neuromyoarterial glomus or glomus body. We report a case of glomus tumor of the lung arising in the left lower lobe, incidentally found in a patient who underwent right bilobectomy for a carcinoma localized in the right upper lobe.

Primary pulmonary glomangioma

“…Males are affected more than females (male to female ratio of 7:1). [8] Our case was a 40-year-old female patient. She was admitted to our hospital with chest pain.…”

“…Pulmonary glomus tumors are usually detected incidentally on chest radiographs. [8] Although glomangiomas are essentially benign lesions, the correct diagnosis has to be confirmed by the histopathological examination since glomangiomas do not present with specific findings in CT, magnetic resonance imaging (MRI) or 2-deoxy-2-[18F] fluoro-D-glucose positron emission tomography. [4] The characteristic morphological and immunohistochemical findings of glomangioma can be easily diagnosed by pathological examination.…”

“…[4,8] It is difficult to distinguish a glomangioma from these tumors and metastatic nodules of the lung, because all of these appear under chest radiological examinations as round, welldelineated mass with strong enhancement. [9] However, these features of glomangioma on chest tomography scans usually distinguish it from lung cancer.…”

Tumor glómico en pulmón: reporte de un caso y revisión bibliográfica

“…La segunda variante, llamada glomangioma, contiene mayor proporción de vasos sanguíneos, generalmente dilatados, simulando un hemangioma cavernoso, y suele ser menos circunscrita que la forma usual. La variante más infrecuente, denominada glomangiomioma, muestra una transición de las células glómicas a células musculares lisas alargadas 3,6 .…”

Gastric glomus tumor with prominent polytypic plasmacytosis: case report and review of literature

“…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] .…”
