Overview
Other diagnostic studies for glomus tumor include immunohistochemistry staining, which demonstrates glomus cells positive for vimentin and alpha-smooth muscle actin and negative for desmin.[1]
Other Diagnostic Studies
- Other diagnostic studies for glomus tumor include immunohistochemistry staining, which demonstrates the following:[1]
- Clinical Tests:
- Love test[2][3]
- Orientative
- Probing with a needle or pointed instrument triggers pain in the affected area but not the area immediately adjacent to it
- Sensitivity= 100%
- Specificity= 0%
- Hildreth sign[2]
- Occurence of pain following induction of ischemia by application of a tourniquet to the glomus tumor mimicking median nail dystrophy (the longitudinal splitting in the midline of the nail)
- Highlights the vascular nature of the lesion
- Sensitivity= 77.4% - 92%
- Specificity= 91% - 100%
- Cold-sensitivity test[4]
- Application of cold water or ethanol to the affected area reproducing the symptoms
- Sensitivity= 100%
- Specificity= 100%
- Transillumination test[4][5]
- Performed in a darkened room by passing light through the finger pad
- An opaque red image is observed in the region of the tumor that allows estimation of its size
- Sensitivity= 23% - 38%
- Specificity= 90%
- Love test[2][3]
