Hibernomas, especially located in the mediastinum, are extremely rare benign tumors, which are important to consider in the differential diagnosis of a heterogeneously enhancing mass with areas of fat attenuation on imaging of an often incidentally discovered mass. Other common possibilities in the differential include malignant tumors, such as liposarcoma, hence histopathology is usually required to confirm the diagnosis. Hibernomas often follow the distribution of sites of persistence of brown fat in adults, and intrathoracic locations are unusual. We present a very rare case of a mediastinal hibernoma in a 53-year-old woman. She presented to the emergency department with severe, progressive right neck and shoulder pain with radiation down her arm and was found to have a right apical posterior mediastinal mass on imaging. Initial radiographs of the shoulder showed a soft tissue mass within the apical right hemithorax. Further imaging with CT revealed a well circumscribed, heterogeneously enhancing mass with areas of fat attenuation. Pathology confirmed the diagnosis of mediastinal hibernoma, and the mass was completely excised. Fourteen months after surgery, the patient had a normal chest radiograph, and thirty-two months after surgery, she remains asymptomatic.

Soft tissue sarcoma (STS) represents a diverse group of malignant tumors derived from mesenchymal elements. Evaluation of a soft tissue mass of the trunk or extremity starts with a detailed history and physical examination, which will help guide further diagnostic evaluation.  Imaging should then be obtained for an STS, with MRI being the preferred modality for the trunk or extremities. Imaging can assist with diagnosis and delineate the extent of the primary lesion, including the relationship to contiguous structures, for treatment planning and assessing resectability. Pathology diagnosis is most commonly performed via examination of a specimen obtained through image-guided percutaneous core-needle biopsy. This requires multidisciplinary planning between Surgery and Radiology to place the needle within the anticipated definitive surgical incision to allow for en bloc resection of the needle tract. Once the diagnosis of an STS is made, appropriate staging studies should be performed based on the history and physical examination and tumor histology, grade, and size. Clinical and pathology data are used to stage STS patients using the American Joint Committee on Cancer staging system, which incorporates the STS site, size and grade of the primary tumor, and absence or presence of nodal and distant metastatic disease.

ABSTRACT Choanal polyp is the term used for benign, solitary soft tissue mass which extend toward the junction of nasal cavity and nasopharynx, i.e. choana. We report a rare case of choanal polyp arising from the middle turbinate and its successful treatment by endoscopic surgery. The complete resection of choanal polyp at the site of origin using an endoscope is usually sufficient and carries good prognosis without recurrence. How to cite this article Gupta M, Singh S.

A rare case of an epitheloid haemangioendothelioma presenting as an aggressive soft tissue mass in the wrist of an infant is presented. The management of the lesion presents particular difficulties because of its diffuse involvement of surrounding muscles, tendons and neurovascular bundle and the importance of preserving hand function. The epitheloid haemangioendothelioma rarely occurs extravascularly with less than 15 such cases reported in the literature.

Background Schwannomas are rare, slow-growing, benign tumors consisting of Schwann cells. They may cause pressure along a bony structure, resulting in increased pain and discomfort. Less than 1% of schwannomas become malignant, and localization in the foot is uncommon (2%–3% of reported cases). Methods We present a case of a schwannoma of a branch of the posterior tibial nerve sheath. The goal is to assist in recognition, diagnosis, and treatment of schwannoma in the foot and ankle. This is a case of a 51-year-old male soccer player with a soft-tissue mass along the medial ankle at the tarsal tunnel area with an insidious onset (2 years). Physical examination revealed a 3.0 × 2.5-cm mass; magnetic resonance imaging confirmed location, size, and depth. Results Surgical resection of the soft-tissue mass was performed under general anesthesia. The mass was found to be superior to the flexor retinaculum and attached by a small nerve branch of the posterior tibial nerve that traveled through the flexor retinaculum. A tissue specimen was sent to the pathology laboratory, and a schwannoma was confirmed histologically. Conclusions Schwannomas can occur after trauma, especially if the posterior tibial nerve or its branches are affected intrinsically or extrinsically, leading to discomfort, pain, and numbness along the tarsal tunnel. Also, unique to this case, a schwannoma may occur along the small branches of the posterior tibial nerve and present anatomically superior to the flexor retinaculum.

Per Se

Vulval malignancies per se are very rare and a liposarcoma in this location is rarer still. The literature consists only of case reports of patients, often with a very limited follow up. We present a rare case of a young 30 year old unmarried nulliparous woman presenting with a giant vulval mass of 30×20 cm and weighing nearly 6 kilograms. Ultrasonography, Computed Tomography, Magnetic Resonance Imaging and biopsy were done. Local resection with adjuvant radiotherapy was given. Histopathology was suggestive of myxoid liposarcoma and the patient is presently recurrence free with over 8 years of follow up. Though rare, myxoid liposarcoma should be kept in differential diagnosis of vulval soft tissue mass. Management includes a combination of surgery and radiation. Excision of lymph nodes is not recommended. Strict prolonged follow up for recurrence or metastasis is mandatory, and any new complaints should be addressed promptly. This is particularly true in the setting of liposarcoma, which may exhibit unusual patterns of spread and recurrence.

Incidental extracardiac findings (ECFs) are commonly noted on cardiac imaging. The majority of the ECFs are noticed on computed tomography (CT), cardiac magnetic resonance scanning, and myocardial perfusion imaging. Although transthoracic echocardiography (TTE) is a widely used cardiac modality, there is scarcity of data describing ECF on TTE. ECFs have the potential to alter patient management. We present a rare case of a cystic mass seen in the posterior mediastinum on TTE, which led to further evaluation and diagnosis of esophagitis with ulceration.

History Of

Primary cardiac lymphoma (PCL) is a rare disease entity that can present with severe cardiac and cardioembolic symptoms. We present a 79-year-old male with history of polymalgia rheumatica on chronic prednisone who presented with a two-week history of progressively worsening dyspnea, cough, and a 10 pound weight loss. Transthoracic echocardiogram (TTE) and computed tomography (CT) of the chest showed a large mediastinal mass with invasion of the pericardium. A biopsy of an abdominal soft-tissue mass confirmed the diagnosis of PCL. The patient was treated with two cycles of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) which was complicated by progressive heart failure requiring substitution of liposomal doxorubicin. The epidemiology, presentation, diagnosis, and treatment options of PCL are discussed.

The findings at radiography, computed tomography and angiography and the clinical course of 30 cases of angiosarcoma were reviewed. The variety of primary sites results in a multitude of findings but the most common finding was that of a hypervascular soft tissue mass seen on CT and angiography. Additional findings of well demarcated cortical defects in long bones were also frequently noted. The general clinical behavior of these aggressive malignant tumors was also reviewed and it was noted that they had a deceptively benign presentation.
