Glomus tumor

Santiago Sánchez Pardo, Javier Duque, Javier Enrique Fajardo
Glomus tumors are uncommon tumors that are originated from smooth muscle cells of the neuromioarterials glomus bodies located in the arteriovenous anastomoses subcutaneous tissue or deep dermis of the extremities, mainly in the palms of the hands, wrists and subungual areas of the fingers. Carcinoid tumor, as the glomus tumor, can show an organoid pattern, increased vascularity, and uniform, round cells with eosinophilic cytoplasm, but usually are positive for cytokeratin and always stained with chromogranin and synaptophysin showing negative for smooth muscle markers which is presented in our case...

We report a 38-year-old woman with a left lung tumor presenting as obstructive pneumonia. Bronchoscopic examination revealed a polypoid tumor filling the left main bronchus. The tumor was partially resected by a snaring procedure for diagnostic purposes. Microscopic examination revealed a submucosal tumor located underneath normal bronchial epithelium. The tumor was composed of sheets of uniform oval to cuboidal cells encompassing numerous blood vessels. Immunohistochemically, the tumor cells exhibited smooth muscle markers, but were negative for neuroendocrine markers...

Osteoid Osteoma is benign bone forming tumor which commonly occurs in long bones of lower limb. Presence of these rare tumors in the distal phalanx of the digits of the hand is considered a rare phenomenon. In hand, they usually present as chronic pain, swelling, nail enlargement and increase in size of digit. Diagnosis is challenging with clinical examination and usual imaging modalities and often confused with glomus tumor, enchondroma, infection, trauma and rheumatic disease. Surgical excision of the tumor, if present in hand, is the treatment of choice that aids in coming to the exact diagnosis too...

Glomus tumors are rare benign hamartomas arising from the neuromyoarterial glomus body, a highly specialized arteriovenous anastomosis responsible for thermoregulation. Although classically associated with a subungual location, less common extradigital glomus tumors can present a diagnostic challenge because of their rarity and nonspecific presentation. This case report adds to the literature of proven extradigital glomus tumors with documented pathologic and magnetic resonance imaging characteristics and describes their place in the differential for soft tissue mass of the wrist...

A 56-year-old woman who was found to have a submucosal tumor (SMT) of the stomach in a medical check-up was admitted to our hospital for a detailed investigation of the SMT. Upper gastrointestinal endoscopy revealed an SMT of 20mm at the anterior wall of the antrum of the stomach. Endoscopic ultrasonography showed a hyperechoic tumor in the fourth layer of the stomach wall. CT examination showed a strongly enhancing tumor on arterial phase images and persistent enhancement on portal venous phase images. Laparoscopy endoscopy cooperative surgery was performed with a diagnosis of SMT of the stomach highly suspicious of a glomus tumor...

Fourteen cases of primary intrathoracic glomus tumor and glomangiosarcoma are presented. The patients were 9 men and 5 women aged 36 to 63 years (mean, 49.5 years). Clinically, 11 patients presented with nonspecific symptoms including cough, hemoptysis, chest pain, and back pain while 3 patients were asymptomatic. Anatomically, 9 tumors were in an intrapulmonary location, 3 in the mediastinum, and 2 in the trachea. Surgical resection was performed in all cases, and grossly the tumors varied in size from 1...

Myopericytoma are uncommon, slow-growing benign perivascular neoplasms that show hemangiopericytoma-like vascular pattern. We report a 52-year-male patient with a painless palpable nodule in the left thumb for the past 9 months. The mass, on the thenar aspect, was 15x12mm in size. X-ray revealed a soft tissue swelling with no bony association. The excised nodule was a non-capsulated, well-circumscribed vascular neoplasm composed of proliferating spindle to ovoid bland cells with eosinophilic cytoplasm. A concentric perivascular arrangement of the cells was seen interspersed by thin-walled, branching, staghorn blood vessels...

Most of the benign intracranial tumors are meningiomas, vestibular schwannomas, pituitary adenomas, craniopharyngiomas, and glomus tumors. Some of them grow very slowly, and can be observed without specific treatment, especially if they are asymptomatic. Symptomatic or growing tumors are treated by surgery, which is the reference treatment. When surgery is not possible, due to the location of the lesion, or general conditions, radiotherapy can be applied, as it is if there is a postoperative growing residual tumor, or a local relapse...

Extradigital glomus tumors are a very rare entity. Here, we report a rare case of a glomus tumor in an atypical anatomic site: the thigh. The clinical features together with the results of MRI, and sonography and Doppler sonographic imaging helped to distinguish glomus tumor of the thigh from other soft tissue neoplasms. The tumor arising from the thigh was excised, and following surgery, the patient was symptom free without evidence of complications or recurrence. There have only been a few previously reported cases describing the use of Doppler sonography in the evaluation of extradigital glomus tumors...

Intravascular glomus tumor in the forearm is very rare and usually presents with persistent pain and focal tenderness. The diagnosis of this condition can be easily missed or delayed. There is no successful treatment so far other than surgical excision in most of cases. We presented a 45-year-old female presented with intravascular glomus tumor in her left forearm. The swelling was excised and the post-operative course was uneventful. Intravascular glomus tumor of the forearm is extremely rare and the persistent pain and tenderness are very suspicious...

Glomus tumors are the benign perivascular tumors that typically present with hypersensitivity to cold, paroxysmal severe pain, and pinpoint tenderness. This tumor is usually subungual lesions and accounts for 1.6% of all soft-tissue tumors. However, extradigital glomus tumors are extremely rare and can be difficult to diagnose, as they typically have a diameter of less than about 1 cm. We report a glomus tumor in the popliteal fossa of a 17-year-old male patient who experienced severe posterior knee pain while playing sports...
