SOUSA, Vítor  e  CARVALHO, Lina. Glomic tumor: Presentation of an infrequent case. Rev Port Pneumol [online]. 2006, vol.12, n.3, pp.269-274. ISSN 0873-2159.

Glomic tumours are perivascular tumours whose cells resemble modified smooth muscular cells of the glomic body. They are more frequent in the subungueal region and rare in the lung. The authors present a case of a 62 year old women with left thoracic pain and great enforces dyspnoea. She presented a solitary nodule in the external basal segment of the LLL, 1.9 cm diameter, circumscribed, firm and with nodular whitish rose cut surface. Glomic tumours are generally benign. They may origin in ectopic glomic cells or be differentiated from non glomic cells. They should be classified as glomic tumor, glomangioma and glomangiomioma according to the relative abundance of glomic cells and of the vascular and muscular components. Pulmonary metastasis of malignant glomic tumours have been described. In these cases an extra pulmonary primary origin must be excluded. The differential diagnosis of glomic tumours of the lung includes the carcinoid, hemangioperycitoma, smooth muscle tumours (epi-thelioid leyomioma) and the paraganglioma.
