True about Glomus- jugulare tumour – a) Most common in male b) Arises from non- chromaffin cells c) Lymph node metastasis seen d) Multicentric e) Fluctuating tinnitus and conductive type of hearing loss seen
**Core Concept**
Glomus jugulare tumors are rare, slow-growing neoplasms originating from the glomus cells of the jugular bulb, which are non-chromaffin paraganglia. These tumors are part of the paraganglioma family, which also includes glomus tympanicum tumors.
**Why the Correct Answer is Right**
Glomus jugulare tumors typically arise from non-chromaffin cells, which is a characteristic feature of these neoplasms. They are more common in women, especially in the 5th and 6th decades of life. The tumors can cause a range of symptoms, including fluctuating tinnitus, conductive hearing loss, and a pulsatile mass in the middle ear. Lymph node metastasis is a rare occurrence, but it can be seen in advanced cases. Multicentric presentation is also possible, where multiple glomus jugulare tumors occur simultaneously.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Glomus jugulare tumors are more common in women than in men.
**Option C:** While lymph node metastasis can occur, it is not a common feature of Glomus jugulare tumors, making this option partially incorrect.
**Option D:** Multicentric presentation can occur, but it is not a universal characteristic of Glomus jugulare tumors, making this option partially incorrect.
**Clinical Pearl / High-Yield Fact**
Glomus jugulare tumors are typically managed surgically, and the goal of treatment is to achieve complete resection of the tumor while preserving surrounding structures. Radiosurgery can also be used as an adjunctive treatment in cases where surgical resection is not feasible.
