Hibernoma of Thigh: A Case Report of 39-Year-Old Male

Introduction: Hibernoma is an uncommon benign lipomatous tumor that originates from residual brown fat. It commonly affects adult patients aged between 30 and 40 with a slight predominance in male more than female and usually seen in the thigh, shoulder, back, chest, axilla, and neck. The present report aimed to highlight on a viable differential diagnosis of thigh mass including liposarcoma and atypical lipoma. Case Presentation: This is the case report with detailed history, examination of 39-year-old male patient with hibernoma over medial aspect of thigh. Marginal surgical resection was carried and sent to histopathology to confirm the diagnosis of hibernoma. Conclusion: Hibernoma is a rare benign lipomatous soft tissue tumor with no known risk for malignant transformation or metastasis. Based on imaging examination, it can mimic malignant tumors such as, liposarcoma, in which we believe that biopsy is required in order to reach the diagnosis in most of the cases.

Superficial Acral Fibromyxoma

Superficial acral fibromyxoma is a rare, benign, slow-growing, soft-tissue tumor commonly located in the acral regions, with a predilection for the great toe, developing from the nail unit. Because of its nonspecific features and rarity, clinical diagnosis is difficult. In this article, we present a case of superficial acral fibromyxoma located in the nail unit with new dermatoscopic and radiologic findings that have not been previously reported in the literature.

Prevalence of Symptomatic Venous Thromboembolism in Patients with Malignant Bone and Soft Tissue Tumors Undergo Surgery without Chemoprophylaxis

Background: The prevalence and risk factors of venous thromboembolism (VTE) in malignant bone and soft tissue tumor patients that undergo surgery is reported in many studies. However, there is lack of studies on the patients without chemoprophylaxis. Objective: To evaluate the prevalence and risk factors for VTE after surgery in malignant bone and soft tissue tumor patients without chemoprophylaxis Materials and Methods: A retrospective medical chart review identified 260 cases of malignant bone and soft tissue tumor operated between 2008 and 2017. Official diagnostic reports were reviewed from the Picture Archiving and Communication System (PACs). The incidence of VTE and its risk factors were assessed using Chi-square test, t-test, and binary logistic regression. Results: The overall prevalence of symptomatic VTE was 0.8% (2/260 patients), all of which had PE. No fatal VTE was detected. Asymptomatic pulmonary embolism (PE) was identified in two patients (0.8%) Mean follow up interval of the available data was 9.5 (3 to 36) months. No significant risk factor was found. Conclusion: The authors found that patients with malignant bone and soft tissue tumors that underwent surgery without chemoprophylaxis in the authors’ center had lower prevalence of VTE when compared to most previous studies whose patient received chemoprophylaxis.

Rare Intramuscular Lipoma of the Foot: A Case Report

Intramuscular lipoma is a rare subset of a more common soft-tissue tumor, lipoma. The etiology is unknown. It is a rare soft-tissue tumor with an overall incidence of less than 1% of all lipomas. Magnetic resonance imaging tends to be the imaging modality of choice, used for surgical preparation. Widely accepted treatment involves local excision. The author presents a case study involving a patient with an abnormally large, recurrent intramuscular lipoma of the left hallux, surgically excised and confirmed by pathology reports. iscussion includes a review of intramuscular lipoma. A review of the literature revealed only two previous reports.
