Multiple intraneural glomus tumors in different digital nerve fascicles.

BACKGROUND: Glomus tumors in the digital nerve are extremely rare. Multiple intraneural glomus tumors in different digital nerve fascicles have not been previously reported. CASE PRESENTATION: We report the case of a 54-year-old male with a 1-year history of progressive numbness of the middle finger with point tenderness at the level of the middle phalanx. Surgical incision revealed the presence of two glomus tumors within different fascicles of the ulnar digital nerve of the middle finger. One tumor was excised along with surrounding fascicle, the other was removed leaving the fascicle intact. Subsequently, the patient regained function of the finger and no tumors have recurred. CONCLUSIONS: Patients and physicians should be aware of the properties of intraneural glomus tumors so that early diagnosis and treatment can be sought.

[A neck chemodectoma--survey of literature and description of one case of malignant chemodectoma]. / Klebczak szyjny--przeglad literatury i opis przypadku klebczaka zlosliwego.

Neck tumors are one of the most difficult diagnostic and therapeutic problems of the contemporary otolaryngology. Therapeutic success mainly depends on early and exact diagnosis. The goal of the study is to pay attention to the necessity of careful diagnosis and introducing computer tomography (CT) as a standard of neck tumors treatment procedure in order not to miss exceptionally rarely neck chemodectoma and to plan treatment process properly. CT can be a first step of vascular diagnostics what implicates safe operation course, providing effects and complications. Chemodectoma is a tumor coming from the parasympathetic part of the nervous system. The authors present a case of neck chemodectoma with malignant character in a 37-years-old woman with 10-years history of suspicion of a benign cyst.

A case of incomplete Carney's triad.

A 62-year-old woman, who had multiple pulmonary nodules noted 6 years earlier, and surgery for a gastrointestinal stromal tumor 2 years earlier, was found to have enlargement of her pulmonary nodules. Surgery was selected to make a definite diagnosis. Thoracoscopic segmentectomy of right segments 9 and 10 was performed, and pulmonary chondroma was diagnosed. Carney designated the combination of 3 rare soft tissue tumors (gastric leiomyosarcoma, pulmonary chondroma, and extraadrenal paraganglioma) as a syndrome. This patient may have had an incomplete type of Carney's triad with 2 lesions in the stomach and lung.

Mediastinal aortosympathetic paraganglioma: report of two cases.

Thoracic paragangliomas or extra-adrenal pheochromocytomas are uncommon neoplasms that may arise from the extra-adrenal paraganglia. Paragangliomas arising in the anterior mediastinum are most frequent and are related to the base of the heart. Paragangliomas of the posterior mediastinum are most infrequent, and arise from aorticosympathetic paraganglia. We present two cases of posterior mediastinum paraganglioma. Complete tumor resection was done through posterolateral thoracotomy. The diagnosis of aorticosympathectic paraganglioma was established by histologic examination.

Aortic paraganglioma requiring resection and replacement of the aortic root.

This case report demonstrates the resection of an aortic root paraganglioma incidentally discovered in a 32-year-old male with replacement of the root for an oncologically complete resection.
