Glomus tumor is usually a small, benign tumor and typically occurs in the dermis or subcutis or soft tissues of the extremities and rarely in the visceral locations. Its bronchopulmonary origin is exceedingly rare clinical condition. The current case reported a 51-year-old male with dyspnea on exertion and obstructive pneumonia; he had a glomus tumor which has large size, deep location and exhibits an infiltrative margin as well as atypical mitotic figures. These characteristic suggests malignant behavior. Therefore diagnosis of glomus tumor of uncertain malignant potential was favored. Recently, the histopathological diagnostic criteria for malignant glomus tumors were defined in the WHO classification of soft tissue and bone tumors 4th edition. Here we also reviewed the literature on primary bronchopulmonary glomus tumors with special attention to the current concept of malignancy grade estimation.

BACKGROUND: Glomus tumors are rare neoplasms accounting for less than 2% of all soft tissue tumors but multiple lesions may be seen in up to 10% of the patients. Solitary glomus tumor (GT) most frequently appears as small nodule in specific locations such as subungual region or deep dermis. However, rarely these entities have been observed in extracutaneous locations such as the gastrointestinal, cardiovascular, respiratory tracts, and other visceral organs. A small fraction of the GTs may present as tumors of uncertain malignant potential or as malignant glomus tumors. CASE PRESENTATION: We report a patient with multiple glomus tumors on the time of diagnosis, which was histologically diagnosed as an atypical glomus tumor following resection of a tumor thrombus in the left renal vein, inferior vena cava trombus with intracardial extension, and mitral valve specimen. The intramuscular lesion from the thigh was diagnosed as a glomus tumor of uncertain malignant potential. Further examinations revealed multiple lesions trough her body: kidneys, breast, heart and subcutaneous tissue. The diagnosis of glomus tumor of uncertain malignant potential versus glomus tumor with low malignant potential could be quite challenging, and the clinical course may be as a determining factor for final diagnosis. CONCLUSION: To our knowledge, this is the only known case of glomus tumor with multiple organ involvement and aggressive biological behavior at presentation.

<div class="WordSection1"><p class="abstract">Glomus tumors are rare soft-tissue neoplasms of the neuromyoarterial glomus body, typically present in adults as small, blue-red papules or nodules of the distal extremities, with most cases involving subungual sites. The majority of glomus tumors are benign, malignant cases have been rarely reported, with such cases typically being locally invasive. 27 years old patient presented with four years history of intermittent swelling, pain in left lower leg. Biopsy of the lesion revealed lobulated vascular tumour composed of endothelial cells showing intracytoplasmic lumina and solid aggregates of tumour cells, divided by intervening fibrocollagenous septae. Glomus tumour of uncertain malignant potential was diagnosed after excision biopsy. Multispeciality team approach was done for complete cure of the condition.</p></div>
