Chemotherapy with inclusion of doxorubicin, ifosfamide for common malignant glomus tumor of soft tissues of forearm (clinical case and literature review)

Abstract

Malignant glomus tumor is an extremely rare, aggressive neoplasm, which is contain from modified glomus body’s cells. The correct morphological diagnosis is difficult, and requires careful differential diagnosis between neuroendocrine tumors, pericytic tumors, smooth muscle neoplasms. The literature describes only sporadic clinical observations, a series of cases and the results of a small number of retrospective studies. Due to the rarity of nosology, the optimal treatment strategy for this disease has not been developed. Most cases, surgical treatment is used in a locally common process. Cases of metastasis of a malignant glomus tumor are extremely rare. There is no consensus on the tactics of systemic treatment to date. In this article, we present a clinical case of achieving stabilization of the tumor process after 5 courses of chemotherapy with doxorubicin, ifosfamide in a 49-year-old patient with a malignant glomus tumor of the soft tissues of the left forearm with metastatic lesion of the tissues of the anterior chest wall on the left with spread to the left small pectoral muscle, 3rd rib and pleural cavity, with metastatic lesion lung parenchyma.
