Synchronous primary glomus tumor in a patient with adenocarcinoma of the ipsilateral lung.

Abstract

Glomus tumors are rare mesenchymal neoplasms arising from the glomus bodies in the deep dermis of the extremities or derive from the modified smooth muscle cells of the normal glomus body. Primary pulmonary glomus tumors are particularly rare and infrequently reported. We report a case of a primary glomus tumor occurring in the lung with adenocarcinoma in the ipsilateral lung as synchronous lung cancers in a 69‐year‐old man. He underwent lobectomy for adenocarcinoma and wedge resection for the glomus tumor with mediastinal lymph node dissection and was doing well without recurrence or metastasis at the last follow‐up.
