Glomangiomas (glomus tumors) are benign vascular tumors commonly located at the distal extremities, are usually subungual lesions, and account for 2% of all soft-tissue tumors. Patients with digital glomus tumors present with hypersensitivity to cold, paroxysmal severe pain, and point tenderness. These tumors are infrequent in the knee area, and when seen are superficial, usually have a diameter of less than 1 cm, which make their radiological diagnosis arduous. We report a noteworthy, unusual case of a large glomus tumor in the popliteal fossa showing biceps femoris infiltration, in a 51-year-old female patient who experienced severe intermittent posterior knee pain for the past 2 years. Magnetic resonance imaging revealed a large popliteal inhomogeneous soft-tissue lesion with irregular margins insinuating the posterolateral musculature mimicking soft-tissue sarcoma. Histopathology revealed a glomus tumor.

Glomus tumors are benign neoplasms that arise from neuromyoarterial glomus bodies. They represent around 1–5% of all soft-tissue tumors. High temperature, sensitivity, and pain and localized tenderness are the classical triad of symptoms. Most glomus tumors represent in the subungual area of digits. Extradigital glomus tumors are a very rare entity. There are rare cases of these tumors reported to be in shoulder, elbow, knee, wrist, even stomach, colon, and larynx. We are reporting a case of a glomus tumor on thigh and discuss the histological and immunohistochemical features.

Abstract Glomus tumor is a benign mesenchymal neoplasm comprising less than 2% of soft tissue tumors. It is composed of cells resembling modified smooth muscle cells of the normal glomus body. The glomus body, a thermoregulator, is a specialized form of arteriovenous anastomosis localized in dermal and precoccygeal soft tissue. Although glomus tumors are rare neoplasms, clinical misdiagnosis of many of these lesions as hemangiomas or venous malformations makes an accurate assessment of their actual prevalence difficult. A malignant counterpart of this lesion exists but is extremely rare.

Glomus tumors are benign neoplasms that arise from neuromyoarterial glomus bodies accounting for <2% of soft-tissue tumors. Glomus tumors represent around 1–5% of all soft-tissue tumors and 1–5% of all hand tumors. About 75% of these tumors occur in hand with 75–90% of these occurring in characteristic subungual location. Extradigital location of glomus tumor is very rare. We report an exceptional case of extradigital glomus tumor causing thigh pain, where there were a pair of lesions both in periosteum and intramuscular location. A 47-year-old male with complaints of pain over medial aspect of the left lower thigh for 2 years on ultrasound revealed well-defined solid hypoechoic lesions within the left vastus medialis muscle and cortical-based lesion abutting the periosteum of distal diaphysis of the left femur on medial aspect. These lesions were hypointense on T1W, hyperintense on T2W and showed early homogenous enhancement on MRI. Histopathology revealed glomus tumors, which commonly occur in digits. Glomus tumors located in both periosteal and intramuscular locations in thigh were in very uncommon. Non-specific presentation with pain in such cases remains a diagnostic dilemma. Role of multimodality imaging and histopathology correlation is important in such situation.

AbstractGlomus tumors are a mostly benign neoplasm that constitutes less than 4% of upper-limb soft-tissue tumors. Its unspecific clinical presentation, added to its low frequency, leads to a late diagnosis.The objective of the present study is to update the clinical-paraclinical approach and the surgical technique used in the treatment.We carried out a literature review from 2014 to 2019 on digital glomus tumor in the hand in adult patients using the PubMed search engine.In most of the publications analyzed, the diagnosis was clinical, with a delay of 1 to 10 years. Plain radiography is the most requested study; of the 16 articles reporting its indication, only half evidenced compatible changes. Magnetic resonance imaging (MRI) was requested in 15 articles, presenting normal results in 3 of them. The treatment of choice was surgical excision using a transungual approach. Only 4 articles report recurrence after excision.Although there is diversity in the approach to these tumors, we conclude that the diagnosis is clinical, and the treatment surgical, and there is no consensus regarding the paraclinical indication. The information available comes mainly from case reports, publications that contribute to the generation of evidence for the clinical practice in rare diseases such as this one.

Background: Soft tissue tumors are defined as mesenchymal proliferations which occur in the extraskeletal non-epithelial tissues of the body, excluding the viscera, coverings of brain and   lymphoreticular system. The objective of this study was to study the histopathological features of soft tissue tumors and to study the occurrence of soft tissue tumors in relation to age, sex and anatomical site.Methods: This study comprised of 89 cases studied over a period of two years. All soft tissue tumors, their gross features, microscopic findings were analysed in detail. Soft tissue tumors were divided into benign and malignant categories and further sub typing were done according to World Health Organization (WHO) classification. The distribution of soft tissue tumors according to the age, sex and site of occurrence was studied.Results: Out of 89 cases of soft tissue tumors, 76 cases were benign, 4 cases belonged to intermediate category and 9 cases were malignant. Adipocytic tumors formed the largest group constituting 39 cases. Vascular tumors were the second commonest (26 cases) followed by peripheral nerve sheath tumors (11 cases). The benign tumors were seen in younger age as compared to malignant tumors. Malignant soft tissue tumors was seen to be more common in male than female and pleomorphic sarcoma and liposarcoma was commonest (3 cases each).Conclusions: Benign tumors were more common than malignant. The most common benign tumors were lipoma followed by hemangioma and schwannoma. The most common malignant tumor was pleomorphic sarcoma. The benign tumors were seen in younger age as compared to malignant tumors.

Glomus tumors are rare neoplasms that usually occur on the hands in a subungual location, or sometimes in palms, wrists or soles of the feet. They are described as purple/pink tiny painful lesions with a triad of pain, local point tenderness, and cold hypersensitivity. They are almost always benign, but rare malignant variants have been reported. They have also been reported to be present at unusual locations, like the lung, stomach, or liver. Gastrointestinal glomus tumors are extremely rare tumors and very few cases have been reported in the literature. Most that have been reported were usually benign in nature. A rare esophageal glomangioma, mimicking a papilloma, was reported in 2006. We report a case of glomangiosarcoma (malignant glomus tumor) in a 49-year-old female, who presented with symptoms of dysphagia including some spasm and hoarseness and subjective unintentional weight loss. On endoscopic exam, she was found to have a distal esophageal mass with malignant features. Radiologically, the mass had a size of about 8 cm on the CT scan without evidence of metastases. Pathology and immunostaining of the biopsy showed features resembling a malignant glomus tumor. She underwent an endoscopic and laparoscopic staging of the tumor along with ultrasound. Based on the laparoscopic findings, which were consistent with the preoperative diagnosis, she was scheduled for an esophagectomy. Histopathology and immunophenotypic features of the excised mass were consistent with a diagnosis of malignant glomus tumor.

AbstractClinicians are commonly faced with patients presenting with a solitary palpable soft tissue mass. Most soft tissue lesions are benign, and not every mass is due to a neoplastic process. Many pathologies can mimic a malignant tumor. Despite appropriate clinicoradiologic assessment, these lesions can be mistaken for a soft tissue sarcoma and can lead to multiple investigations or an intervention, inconveniencing patients and leading to an increased health care cost. With the relevant clinical history, clinical examination, and specific imaging characteristics, the diagnosis can be narrowed. We present a pictorial review of soft tissue sarcoma mimics with guidance on appropriate differential diagnoses.

History Of

Glomus tumors are mesenchymal neoplasms derived from glomus bodies with rare presentations in the oral cavity. Glomus tumors present as a purple or pink vascular nodule or papule, sized <1 cm, and imitate vascular neoplasms such as hemangiopericytoma or hemangioma. Glomus tumors represent less than 2% of all benign soft tissue tumors. Only 27 cases of benign glomus tumors with oral cavity involvement have been reported to date. The most-reported oral tumors involved the lips (54.2%), followed by hard palate, gingiva, tongue, and buccal mucosa. The mean age of presentation of the labial glomus tumors is 48.7 years, with no gender predilection, in contrast to the subungual site, which occurs more in females. The etiology of the glomus tumors remains unknown. Subungual glomus tumors present as stabbing pain, cold intolerance, and tenderness of the fingertips, whereas labial glomus tumors mostly present as a painless, small, and slow-growing lesion. Treatment is surgical resection of the tumor. The recurrence rate of labial glomus tumors is unclear. In this article, we present the case of a 62-year-old man with a 2-month history of painless, soft lump on the mucosal surface of the lower left lip. Excisional resection of the tumor was performed in the clinic, and the histopathologic finding was consistent with solid glomus tumor. At 1 year follow-up there was no recurrence.

Glomus bodies are neuromyoarterial apparatuses of the skin, implicated in body temperature control, and may undergo transformation with unregulated hyperplasia of their smooth muscle component. Glomus tumors most commonly occur in the subungual region of the fingers. These benign tumors are rare and constitute 1-5% of soft tissue tumors of the hand and may present as solitary or multiple masses. Solitary glomus tumors present with a classic triad of localized tenderness, severe pain, and cold sensitivity. We report a rare case of glomus tumor in the elbow and a review of the histopathological findings.
