Intraoral fibrolipoma: case report and review of literature

Introduction: Lipomas are benign soft tissue tumors, characterized by the presence of mature adipocytes in histopathology. Their development is slow and their etiologies are still controversial. Frequently subcutaneous, this type of lesion is rarely present in the oral cavity. Observation: A 67-year-old man consulted for a nodule on the inner face of his right cheek which had been developing for several years, with severe discomfort during chewing. The typical clinical aspect of this lesion suggested a lipoma. Magnetic resonance imaging (MRI) was performed before surgical excision in order to establish a differential diagnosis with a well-differentiated liposarcoma. Comments: The various imaging examinations, particularly MRI, combined with the analysis of the fat component and the morphology of the non-fat component (septa) enable us to define several categories of lesions likely to have a benign or malignant character. However, some lesions remain difficult to classify, and it is the histopathological examination along with, if necessary, immunohistochemistry (anti-MDM2 and/or anti-CDK4), which allows to confirm or not the malignancy of a lesion. Histological examination suggested a fibrolipoma. Conclusion: Although benign, the size of a fibrolipoma may can lead to significant functional and aesthetic discomfort for the patient. Surgical excision remains the treatment of choice.

AbstractThe present study is a case report of vulvar lipoma. The vulva is a rare site for the development of lipomas, and the aim of the study is to determine if the current imaging modalities can diagnose lipomas correctly. A 43-year-old patient presented with a painless, slowly progressive, oval, mobile and non-tender right vulvar mass compressing the vagina and totally covering the introitus. Both the ultrasonography and magnetic resonance imaging (MRI) exams suggested the diagnosis of lipoma. Surgical excision was performed, and the histopathological examination of the mass confirmed a lipoma.

Response To Chemotherapy

: Differentiation of malignant from benign soft tissue tumors is challenging with imaging alone, including that by magnetic resonance imaging and computed tomography. However, the accuracy of this differentiation has increased owing to the development of novel imaging technology. Detailed patient history and physical examination remain essential for differentiation between benign and malignant soft tissue tumors. Moreover, measurement only of tumor size based on Response Evaluation Criteria In Solid Tumors criteria is insufficient for the evaluation of response to chemotherapy or radiotherapy. Change in metabolic activity measured by 18F-fluorodeoxyglucose positron emission tomography or dynamic contrast enhanced-derived quantitative endpoints can more accurately evaluate treatment response compared to change in tumor size. Magnetic resonance imaging can accurately evaluate essential factors in surgical planning such as vascular or bone invasion and “tail sign”. Thus, imaging plays a critical role in the diagnosis and treatment of soft tissue tumors.

An 11-year-old male Rough collie was submitted with paraparesis, but did not respond to medical treatment. Clinical signs worsened and the dog displayed paralysis, inability to stand and loss of voluntary bladder control, whereupon magnetic resonance imaging (MRI) was performed. No significant abnormalities were identified from MRI, blood tests, cerebrospinal fluid tests or radiography. After MRI, the dog developed dyspnoea and died. Autopsy and subsequent histopathological examination led to a diagnosis of degenerative myelopathy.

ABSTRACT Pleomorphic adenoma is a benign tumor of the salivary glands, most commonly affecting the parotid gland. Pleomorphic adenoma of the ear is rare. The use of imaging modalities, especially magnetic resonance imaging (MRI), is particularly useful in localizing and surgical planning of these tumors. We present a case of pleomorphic adenoma invading the mastoid cortical bone, with review of literature. How to cite this article Vamanshankar H, Parida PK.

Mri Characteristics

Schwannomas are benign soft-tissue tumors that arise from peripheral nerve sheaths throughout the body and are commonly encountered in patients with neurofibromatosis Type 2. The vast majority of schwannomas are benign, with rare cases of malignant transformation reported. In this pictorial review, we discuss the magnetic resonance imaging (MRI) appearance of schwannomas by demonstrating a collection of tumors from different parts of the body that exhibit similar MRI characteristics. We review strategies to distinguish schwannomas from malignant soft-tissue tumors while exploring the anatomic and histologic origins of these tumors to discuss how this correlates with their imaging findings. Familiarity with the MRI appearance of schwannomas can help aid in the differential diagnosis of soft-tissue masses, especially in unexpected locations.

Resonance Imaging

Dermoid cysts are rare benign tumors that arise from ectopic epiblastic inclusions and account for 0.4% to 1.5% of all tumors. They are usually 1 to 5 cm in size and composed of a pasty semisolid material. The orbital dermoid cyst is the most common type. Dermoid cysts can also occur in the spinal cord, ovaries, and pancreas. We encountered a 24-year-old man with a dermoid cyst over the left sternoclavicular joint. He reported intermittent secretion of a white tofu-like exudate from an underlying congenital sinus tract since birth. The secretion had turned hemorrhagic for the last month and had been accompanied by progressive swelling and pruritus for 1 week. Ultrasonography and magnetic resonance imaging revealed characteristics of a dermoid cyst, and histopathological examination confirmed the diagnosis. The patient underwent surgical excision of the cyst under local anesthesia. The incision healed well with no postoperative complications. Considering that a dermoid cyst has the potential to become infected or progress into squamous cell carcinoma, its removal at an early stage is suggested. Few reports in the literature have described a dermoid cyst that secretes hemorrhagic contents from a congenital sinus tract. We present this case to provide a reference for clinicians.

Subdural osteomas are extremely rare benign neoplasms. Here, we report the case of a 35-year-old female patient with a right frontal and parietal subdural osteoma. The patient presented with a 2-year history of intermittent headache and fatigue. Computerized tomography (CT) scan showed a high-density lesion attached to the inner surface of the right frontal and parietal skull. Magnetic resonance imaging (MRI) demonstrated T1 hyperintensity and T2 hypointensity of the lesion. Intraoperatively, the hard mass was located in subdural space and attached to the dura mater. Histopathological examination revealed lamellated bony trabeculae lined by osteoblasts and the intertrabecular marrow spaces occupied by adipose tissue. The patient underwent neurosurgical resection and recovered without complication. Surgical excision is recommended to extract the symptomatic lesions with overlying dura mater.

Imaging evaluation of uterine masses is important to assess the type of lesion and to target surgery, if surgical excision is necessary. This can be decisive in fertile women with benign masses resembling malignancies, in order to avoid overtreatment. In this study, the magnetic resonance imaging (MRI) appearance of cotyledonoid dissecting leiomyoma of the uterus, a rare benign variant of leiomyoma mimicking malignancy, is presented.
