Various types of tumor can occur in the subungual space, including glomus tumors, subungual exostosis, hemangioma, epidermal cysts, and malignant tumors. While fibromatosis can occur at various sites throughout the body, it is very rarely seen in the toe. Here, we are the first to report a case of superficial fibromatosis mimicking a glomus tumor in the subungual space of the second toe. The presentation of this condition shows the possibility of encountering uncommon superficial fibromatosis in the distal phalanx of the toe, and suggests that superficial fibromatosis should be included in the differential diagnosis of a glomus tumor in the toe.

Objective: To investigate the clinicopathological features of glomuvenous malformation (GVM). Methods: Thirty-one cases of GVM diagnosed at the Henan Provincial People's Hospital from January 2011 to December 2021 were collected. Their clinical and pathological features were analyzed. The expression of relevant markers was examined using immunohistochemistry. The patients were also followed up. Results: There were 16 males and 15 females in this study, with an average age of 11 years (range, 1-52 years). The locations of the disease included 13 cases in the limbs (8 cases in the upper limbs, 5 cases in the lower limbs), 9 cases in the trunks, and 9 cases in the foot (toes or subungual area). Twenty-seven of the cases were solitary and 4 were multifocal. The lesions were characterized by blue-purple papules or plaques on the skin surface, which grew slowly. The lumps became larger and appeared to be conspicuous. Microscopically, GVM mainly involved the dermis and subcutaneous tissue, with an overall ill-defined border. There were scattered or clustered irregular dilated vein-like lumens, with thin walls and various sizes. A single or multiple layers of relatively uniform cubic/glomus cells were present at the abnormal wall, with scattered small nests of the glomus cells. The endothelial cells in the wall of abnormal lumen were flat or absent. Immunohistochemistry showed that glomus cells strongly expressed SMA, h-caldesmon, and collagen IV. Malformed vascular endothelial cells expressed CD31, CD34 and ERG. No postoperative recurrence was found in the 12 cases. Conclusions: GVM is an uncommon type of simple venous malformation in the superficial soft tissue and different from the classical glomus tumor. Morphologically, one or more layers of glomus cells grow around the dilated venous malformation-like lumen, which can be combined with common venous malformations.

OBJECTIVETo investigate the clinical features, early diagnosis and surgical treatment of the hand glomus tumor in the female.

METHODSThirty female patients with the hand glomus tumor underwent early resection by microsurgery. The average age was 35 years ranging from 18 to 48 years. The course of disease was from 3 months to 3 years. All patients' tumors occured on single finger.

RESULTSIn the 30 cases, there were 28 patients with localized eminences and hepatic plaques under the nail. The compression of distal phalanx could be seen on radiographs in 18 patients, definite and localised tenderness on nails could be found in all cases, the tenderness disappeared and no recurrence after 15 months of follow-up in all cases.

CONCLUSIONThe hepatic plaque under the nail and fixed tenderness point on the nail are of significance in diagnosis for the hand glomus tumor in the female, the early microsurgical resection is unique effective treatment to this disease.

OBJECTIVEDiscuss the surgical treatment of jugular foramen and hypoglossal canal tumor, and choice of the best surgical approach.

METHODS32 patients with jugular foramen and hypoglossal canal tumor were operated through the postauricular tran-supracondylar approach, 13 neurinoma, 7 glomus jugular tumors, 4 meningioma, 3 chordoma. 23 were total removed, with a subtotal of 9.

RESULTS21 patients were followed up, mean 2.5 years. 18 patients work normally, 7 of them were hoarseness, 2 of other 3 patients lived by themselves, 1 of existed obstruct of limbs.

CONCLUSIONSPostauricular tran-supracondylar approach exposes satisfactory for the dumbbell-shape tumors of intra-or extra cranial. It has high rate of total removal and low rate of complications. It is the best approach of treatment in jugular foramen and hypoglossal canal tumors. The outcome is good.

OBJECTIVE: To investigate diagnosis method and treatment experience of jugulare glomus tumor (JGT) and carotid body tumor (CBT). METHOD: Retrospective analysis. Clinical materials from 4 patients at one genealogy with JGT and CBT were collected. The clinical features, radiological characteristics, surgical methods and prognosis were assessed. The proband suffered from left JGT and left CBT, her younger sister had right CBT as well as her younger female cousin had bilateral CBT and right JGT, her older male cousin had bilateral CBT and left JGT. These JGT and CBT in four patients were resected under general anesthesia after preoperative ultrasound, CT or CT angiography (CTA), MRI, and digital subtraction angiography (DSA) examination as well as preoperative vascular embolization. RESULT: The surgery was uneventful in four cases, and there was no hemiplegia or deaths. All patients were followed up for 2 years to 29 months without recurrence. Six months after operation, the hoarseness also disappeared in the older male cousins but did not improve significantly in younger female cousin. The younger female cousin get right peripheral facial paralysis 1 year after surgery and her temporal bone CT indicated a right JGT. CONCLUSION It is very important to assess JGT and CBT by Ultrasound, CT, CTA, MRI and DSA. Surgical resection is the first optional treatment for JGT and CBT. Blood loss can be reduced by preop erative vascular embolization. Serious complications could be avoid by operating under microscope, which can supply a clear surgical field and make the surgeon to protect the large blood vessels and nerve.

We present a rare case of glomus tumor of Hoffa's fat pad in a 42-year-old woman. Magnetic resonance imaging findings along with the characteristic clinical picture led us to suspect a glomus tumor as the possible etiology. An ischemia test was found to be positive and this further substantiated our diagnosis. An arthroscopic excision was performed and the histology confirmed the diagnosis of glomus tumor of Hoffa's fat pad. The patient responded well to the excision with immediate complete resolution of pain and she remains asymptomatic at the last follow-up after 15 months. To our knowledge, this is the second reported case of glomus tumor of Hoffa's fat pad and the first ever to be managed by simple arthroscopic excision. The tumor poses a great challenge to an orthopedic surgeon. However, knowledge of its characteristic clinical presentation and the recognition of such a rare entity can help achieve an early diagnosis and timely management.

OBJECTIVETo investigate the administration of far lateral craniocervical approach in the jugular foramen (JF) tumors.

METHODSA retrospective analysis was performed in 14 cases of JF tumors (9 neurilemmomas, 3 meningiomas, 1 glomus jugulare tumor, and 1 adenoid cystic carcinoma) surgically treated between January 2009 and January 2012, with focus on the surgical approach. Six patients (6/14) showed hydrocephalus. The tumor type was composed of 5 intracranial and intraforamen tumors with patent or occluded jugular bulb, 1 intracranial tumor with extension into the upper cervical canal, 4 extracranial and intra foramen tumors, 4 intra- and extracranial dumbbell-shaped communicating tumors involving the parapharyngeal space above C2 or extending caudally below C3. Far lateral postcondylar approach (FLPC) was carried out in 2 cases, far lateral tansjugular process approach (FLTJP) in 3 cases, combined FLPC + C1-2 semi-laminectomy approach in 1 case, combined FLTJP + trans-C1 transverse process approach in 7 cases, and combined FLTJP + neck approach with dissection of carotid sheath to the skull base in 1 case. Endovascular embolotherapy prior to surgical resection was performed in 1 glomus jugulare tumor.

RESULTSTotal tumor removal was achieved in 12 patients and subtotal removal in 2 patients, with no cerebrospinal fluid leakage or operative mortality. New cranial nerve paresis occurred after surgery in 1 case of facial nerve and 1 case of lower cranial nerve. Transient worsening of preoperative lower cranial nerve deficits was noted in 3 patients. Long-term follow-up study ranging from 5 to 32 months (average 13.7 months) showed 7 patients with lower cranial nerve deficits (6 preexisting and 1 new), with exception of one preoperative lower cranial nerve dysfunction due to the infiltration of an adenoid cystic carcinoma, experienced favorable improvement with recovery of adequate swallowing function, but voice disturbance remained in 4 cases. One patient with new facial nerve deficit presented with partial improvement and the hydrocephalus in 6 patients all spontaneously regressed. There was no tumor recurrence in patients receiving total removal and no tumor progression in patients undergoing subtotal removal.

CONCLUSIONSFLTJP is a basic approach for JF tumors. The combined cranial and cervical approach should be considered in those tumors extending into the upper cervical canal and parapharyngeal space. The associated hydrocephalus seldom requires additional surgical management.
