What is glomangioma?
Abnormal collections of glomus cells, called glomangiomas or glomus cell tumors, are benign clusters of bluish-purple nodules that are often painful and sensitive to pressure. Glomangiomas are benign but can be annoying, and patients may develop clusters in any part of the body.
What is glomus Jugulare?
A glomus jugulare tumor is a tumor of the part of the temporal bone in the skull that involves the middle and inner ear structures. This tumor can affect the ear, upper neck, base of the skull, and the surrounding blood vessels and nerves.
Where on the skin are glomus tumors most likely to be found?
Glomus tumors occur most commonly in the subungual region of the fingers, but may also occur in areas of the body that are not richly endowed with glomus apparatus (e.g., muscle, bone, blood vessels, and nerves).
Can a glomus tumor grow back?
Glomus tumor is a benign condition in which a complete excision usually leads to cure, with low incidence of recurrence. However, this benign condition has an unusually high morbidity to the patient before the correct diagnosis is made.
How rare is a glomus jugulare tumor?

How common is a glomus tumor?
Glomus tumors are rare, benign perivascular hamartomas of the glomus apparatus. In rare cases, large visceral lesions may be malignant . Glomus tumors are usually under one centimeter in size and consist histologically of glomus bodies.
What is the histopathology of glomangioma?
Multiple glomangiomas are rare and comprise about 10 percent of all glomus tumours. In glomangioma, the histopathology shows dilated venous channels that resemble venous malformations (figures 1, 2). Unlike venous malformations, they demonstrate single to multiple rows of surrounding cuboidal glomus cells (figures 3,4).
What are the symptoms of glomangioma and glomus tumor?
They are usually associated with multiple and familial lesion. Glomangioma as with glomus tumour also presents with hypersensitivity to cold, severe pain and pinpoint tenderness to blunt palpation.
What causes pin point pain with glomangioma?
The extreme pin point pain is a characteristic of glomus tumor and alongside this extreme pain it can be easily diagnosed. Glomangioma is a highly vascularised variant of glomus tumor and is a rare, slow growing benign tumor of dermis or subcutaneous tissue.
What is the difference between glomangioma and glomus?
June 2018. Glomangiomas (also called glomuvenous malformation) differ clinically from glomus tumors in that they occur in childhood and adolescence, are usually asymptomatic, do not have a predilection for the subungal region, and often are multifocal.
