We report four cases of chronic obscure pain in the finger tips. High-resolution magnetic resonance imaging (HR-MRI) findings helped diagnose the existence of a mass at the subungual area and all patients were treated with excision and biopsy. The pathological diagnosis was glomus tumor. HR-MRI is useful in the diagnosis of patients with subungual glomus tumor.

Glomus tumours are benign, soft tissue tumours, usually of fingertips. Classically they present with severe pain, temperature sensitivity and localised tenderness. The diagnosis is often delayed due to sometimes non-specific symptoms and rarity of the disorder. While usually a clinical diagnosis, imaging may be necessary for diagnosis and localisation. We present a case of glomus tumour of the ...

Malignant glomus tumor, or glomangiosarcoma, is a very rare mesenchymal neoplasm that, when seen, occurs in visceral organs. Despite having histologic features of malignancy, these tumors usually do not metastasize. However, when metastasis occurs, this disease is often fatal. Our report presents the case of a 59-year-old female patient with a highly aggressive and widely metastatic glomus tumo...

Glomus tumours involving the middle ear and the cerebellopontine angle are reported with emphasis on audiological findings. Magnetic resonance imaging (MRI), angiographic and pathological results are presented. Audiological tests, including impedance audiometry, evoked otoacoustic emissions and auditory brainstem responses, are valuable in evaluation of the effect of glomus tumours on the audit...

Nasopharyngeal extension of the glomus tympanicum is rare. Only 2 cases have been reported in the literature to date. We present a reported case of a large nasopharyngeal extension of recurrent glomus tympanicum, with various kinds of imaging and histopathology and a review of the literature.

Glomus tumor of the trachea is a rare disease. A glomus tumor of the trachea in a 70-year-old man is described. The tumor was successfully excised with rigid bronchoscopy. Twenty-four months after treatment there remains no evidence of endobronchial regrowth at bronchoscopy or imaging studies. Histologic features and treatment are discussed.

Glomus tumours are rare in adults, and such tumours may be associated with neurofibromatosis-1 (Nf-1). Here we describe successful treatment of two glomus tumours initially in the long finger and, one year later, in the thumb in a 17-year young girl with Nf-1.

Chronic intermittent hypoxia (CIH) is a hallmark manifestation of sleep apnea. A heightened carotid body activity and the resulting chemosensory reflex mediate increased sympathetic nerve activity by CIH. However, the mechanisms underlying heightened carotid body activity by CIH are not known. An elevation of intracellular calcium ion concentration ([Ca(2+)]i) in glomus cells, the primary oxyge...

The authors report a rare case of subungual glomus tumor in the right hallux, which was excised with complete relief of symptoms. They provide a brief description of histological features and review the literature.
