Tumour Glomus

Glomus tumors are a very rare mesenchymal neoplasm, it happen less than 2% of all soft tissue tumors. It can be benign, borderline and malignant. The most common location were subungual, however it also can grow at the body organ and extremities. A 60-year-old male patient with firmly defined 1,5 cm diameters tumor mass at the proximal 1/3 proximal cruris region. He was complaining long history of pain and it spreading from the lesion area to the sole of the foot in the last 1 year occasionally. The pain improves at rest. An excisional biopsy was performed with macroscopic features of rounded tissue gray-white color and tender. On microscopic examination, there are neoplastic cell proliferation arranged in a solid pattern, with spherical cell morphology, amphophilic to eosinophilic cytoplasm with spherical nucleus in the middle without atypical nuclear sign. Besides that, there is focal area of stromal hyalinization. No visible mitosis. Based clinical and histopathology feature, the patient is diagnosed as a glomus tumor. The prognosis is quite good because the location and size of the tumor allowing for complete surgical excision and the possibility of recurrence are very rare.
