Glomus tumor is an uncommon, benign, soft-tissue lesion in which the cells recapitulate the structure of the normal modified smooth muscle cells of the glomus body. Glomus tumors usually occur in tissues that normally contain glomus bodies; only rarely can they develop in sites where glomus bodies are normally sparse or absent. There are three subtypes of glomus tumor, with glomangiomyoma being the rarest. No more than 10 cases of glomus tumor in female genitalia have previously been reported, involving the vulva, vaginal area, periurethral area and clitoris. A clitoral glomangiomyoma is extremely rare. This is a case report of a glomangiomyoma in the clitoral area. Published reports of glomus tumor in the female external genitalia are reviewed.

Background: Glomus tumors are rare, benign mesenchymal neoplasms predominantly located in subungual regions of the extremities. Their occurrence in the mandibular region is exceptionally uncommon, presenting unique diagnostic challenges. Only a limited number of submandibular glomus tumors have been documented, leaving their presentation and management largely underexplored.

Introduction: Glomus tympanicum is a benign tumor classified under the group glomus tumors, and is also known as paragangliomas.
Case Presentation: A 52 years old woman presented with unilateral pulsatile tinnitus and hearing loss. She had a visible reddish mass behind the eardrum; Temporal bone CT scans suggested middle ear mass secondary to Glomus Tympanicum tumors.

Objectives: Glomangiomas are benign vascular malformations that exist within the spectrum of glomuvenous malformations which consist of varying amounts of glomus cells, vascular spaces, and smooth muscle. Glomangiomas are often treated due to associated pain, particularly when located on pressure areas such as the back or extensor surfaces, which can cause difficulty with certain activities and occupational functions. Histologically glomangiomas consist of prominent dilated vascular spaces lined by glomus cells typically situated in the deep-dermis to subcutaneous fat which limits treatment to modalities capable of reaching the depth of the tumor including excision, sclerotherapy, and laser therapy.

Juxtaglomerular cell tumor (JxGCT) is a rare type of renal neoplasm demonstrating morphologic overlap with some mesenchymal tumors such as glomus tumor (GT) and solitary fibrous tumor (SFT). Its oncogenic drivers remain elusive, and only a few cases have been analyzed with modern molecular techniques. In prior studies, loss of chromosomes 9 and 11 appeared to be recurrent.

Introduction: The ZAP-X® Gyroscopic Radiosurgery System (ZAP Surgical Systems, Inc., San Carlos, CA, USA) is expected to be a highly accurate next-generation treatment system that enables gyro-stereotactic irradiation of intracranial lesions. In this study, we report the initial treatment course using ZAP-X for intracranial lesions that recurred after Gamma Knife (GK) treatment.
