As glomus bodies are located in the peripheral parts of the human body, these tumours are peripherally located, classically the subungual region, hands, feet and trunk. While being evaluated for renal problems, a middle aged lady was incidentally found to have a gastric tumour. Read More

    Yuan-Mao Lin, Nai-Chi Chiu, Chien-An Liu, Yi-Hong Chou, Yi-You Chiou, Division of Gastrointestinal Radiology, Department of Radiology, Taipei Veterans General Hospital, Taipei 11217, Taiwan.
    Although gastric tumors have overlapping radiologic appearances, some unusual tumors may present specific imaging features. Using multidetector computed tomography (MDCT), with water as a negative oral contrast agent and intravenous contrast medium, can provide critical information for the diagnosis of gastric diseases. In addition, MDCT can evaluate the involvement of the gastric wall and extragastric extent of the disease, as compared with gastroenteroscopy and double-contrast upper gastrointestinal study.

    Rare Tumors 2017 Mar 28;9(1):6848. Epub 2017 Mar 28.
    Division of Thoracic Surgery, Department of Surgery, University of Pennsylvania, Philadelphia, PA, USA.
    Glomus tumors are rare neoplasms that typically occur within the dermis or subcutis of the subungual space. Primary glomus tumors of the thorax are exceedingly uncommon, thus standard-of-care management is lacking. In this report we describe the management of a patient presenting with a symptomatic glomus tumor of the posterior trachea, and provide a comprehensive review including all documented tracheal glomus tumor reports.

    Department of Pathology and Laboratory Medicine, Cedars-Sinai Medical Center, Los Angeles, CA, 90048, USA; Department of Pathology and Laboratory Medicine, University of Tennessee Health Sciences Center, Memphis, TN, 38163, USA. Electronic address:
    The pericytic (perivascular myoid cell) family of tumors is a distinctive group of mesenchymal neoplasms encountered in superficial sites and only rarely seen in viscera. The pericytic family subtends a spectrum of lesions, namely, glomus tumors and variants; myopericytoma, including myofibroma; and angioleiomyoma. In light of the contemporary classification of pericytic lesions, we identified and reviewed 17 cases of renal pericytic tumors from the files of 6 referral centers. Read More

    Intraneural glomus tumor of "uncertain malignant potential" and with BRAF mutation in the median nerve - an unusual case.
    Clin Neuropathol 2017 Jul/Aug;36(4):164-170
    A glomus tumor of uncertain malignant potential is defined as a glomus tumor with some, but not all, criteria for malignancy and without a known metastasis. Here, we present a rare example presenting in the median nerve in a 40-year-old woman with a long history of severely impaired left median nerve function. A large panel of immunohistochemical stains excluded other diagnoses, and the designation of a "uncertain malignant potential" was based on the high proliferative activity, the tumor size and location, and the lack of WHO malignancy criteria such as marked nuclear atypia, necrosis, or atypical mitoses.

    Subungual Glomus Tumours: Is Magnetic Resonance Imaging or Ultrasound Necessary for Diagnosis?
    Malays Orthop J 2017 Mar;11(1):47-51
    Department of Orthopaedics, Grande International Hospital Kathmandu, Nepal.
    Introduction: Diagnosis of subungual glomus tumour is mostly based on detailed history and clinical examination. Recently, Magnetic Resonance Imaging (MRI) and Ultrasound have been proposed as the imaging modality to confirm the clinical diagnosis and in planning the surgical management of these tumours. However, these imaging modalities are not routinely available in rural setting and also are expensive. Read More

    The Risk of Radiation-Induced Tumors or Malignant Transformation After Single-Fraction Intracranial Radiosurgery: Results Based on a 25-Year Experience.
    Int J Radiat Oncol Biol Phys 2017 Apr 9;97(5):919-923. Epub 2017 Jan 9.
    Department of Radiation Oncology, Mayo Clinic College of Medicine, Rochester, Minnesota.

    Vagal paragangliomas are rare benign tumors accounting for only 3% of head and neck paragangliomas and arise from vagal ganglions, predominately the nodose ganglion in the carotid sheath. Imaging plays an important role in their diagnosis, differentiation from more common lesions presenting in the carotid space, and management. MRI is the method of choice for investigation when paragangliomas are clinically suspected. Read More

    Eur J Endocrinol 2017 Jun 3;176(6):R269-R282. Epub 2017 Mar 3.
    School of MedicineUniversity of Belgrade, Belgrade, Serbia
    Hypopituitarism is defined as one or more pituitary hormone deficits due to a lesion in the hypothalamic-pituitary region. By far, the most common cause of hypopituitarism associated with a sellar mass is a pituitary adenoma. A high index of suspicion is required for diagnosing hypopituitarism in several other conditions such as other massess in the sellar and parasellar region, brain damage caused by radiation and by traumatic brain injury, vascular lesions, infiltrative/immunological/inflammatory diseases (lymphocytic hypophysitis, sarcoidosis and hemochromatosis), infectious diseases and genetic disorders.

    [The experience with the surgical treatment of glomus tumours].
    Vestn Otorinolaringol 2017;82(1):15-19
    I.M. Sechenov First Moscow State Medical University, Moscow, Russia, 119991.
    Introduction: glomus tumours of the temporal bones rank second after neurinomas of the VII-th pair of cranial nerves among the pathological conditions that are likely to cause hearing mpairment. Being extensively vascularized locally invasive neoplasms, glomus tumours constitute a serious challenge for the surgeon because of their localization in the vicinity of the vitally important vascular and neural structures of the lateral skull base.

    Aim: To characterize some peculiar features of the surgical interventions and postoperative management of the patients presenting with different types of glomus tumours. Read More

    Department of Neurosurgery, Baylor College of Medicine, Houston, Texas, USA; Department of Neurosurgery, The University of Texas M. D. Anderson Cancer Center, Houston, Texas, USA. Electronic address:
    Background: Carotid body paragangliomas are rare, usually benign, tumors arising from glomus cells of the carotid body. Bilateral involvement is present in ∼5% of sporadic cases and up to one third of familial cases. In most patients undergoing bilateral resection of carotid body tumors, a condition known as baroreflex failure syndrome (BFS) develops after resection of the second tumor characterized by headache, anxiety, emotional lability, orthostatic lightheadedness, hypertension, and tachycardia.

    Glomangiosarcoma Arising from a Prior Biopsy Site.
    Plast Reconstr Surg Glob Open 2017 Jan 25;5(1):e1219. Epub 2017 Jan 25.
    Department of Surgery, New York Presbyterian-Brooklyn Methodist Hospital, Brooklyn, N.Y.; and The Combined Division of Plastic Surgery, New York-Presbyterian Hospital (Weill Cornell Medicine), New York, N.Y.
    Glomangiosarcoma represents a rare malignant variant of the benign glomus tumor that typically presents as a tender, slowly growing nodule with a predilection for the lower extremities. Unlike their benign counterparts, glomangiosarcomas may display aggressive characteristics such as large size, local invasion, and a tendency to recur after excision. Although wide local excision remains the treatment of choice, rare cases of systemic metastasis have been previously reported. Read More
