Introduction : Myxomas are rare benign tumors of soft tissue, represent 1% of adult cancers, they are most often located in the intramuscular compartment, particularly in the thigh. They are most often observed in elderly patients between fifth and seventh decade, particularly females.Case report : We present the case of a 60-year-old man with a painless and several years progressive mass of the medial aspect of the left thigh. Magnetic Resonance Imaging (MRI) has showed a tissue mass with cystic lesion. In addition, histopathological diagnosis of the specimen was in favor of an intramuscular myxoma without signs of malignancy. Short and long-term follow-up of two years did not detect any recurrence.Conclusion : The slowly growing character is not an argument of benignity, in contrast to other situations. Therefore, the myxoid component may be present in other soft tissue malignant tumors, specially liposarcoma. This difficulty sometimes imposing more specimen verification or a second opinion. Although myxomas are rare, it is important to keep them in mind when a myxoid component is present and distinguish them from sarcomas.

Introduction. Chondromas are uncommon benign tumors of cartilaginous origin. Although chonodroma of the jaw is extremely rare, the commonly involved are the anterior portion of the maxilla, condyle and coronoid process. A chondroma is a painless, slow growing tumor causing destruction and exfoliation of teeth. On a radiograph, the tumor appears as a cyst-like radiolucent lesion, while some are sclerotic. The borders are usually ill-defined. Irregular calcifications may be seen with radiolucencies and then it is an osteochondroma. Material and Methods. We present a patient with a resected and histologically proven chondroma of the skull base and maxilla. A 65-year-old female was admitted to our clinic with swelling and breathing difficulties. MRI showed a large soft tissue mass of the skull base and maxilla. Clinicopathological and radiological features were examined by computed tomography (CT) and magnetic resonance imaging (MRI). Discussion and Conclusion. Chondromyxoid fibroma (CMF) is a rare, benign cartilaginous tumor that often occurs in the metaphyses of proximal tibia, proximal and distal femur and small bones of the foot. The differential diagnosis is wide and includes simple or aneyrismal bone cyst, giant cell tumor, nonossifying fibroma, fibrous dysplasia, enchondroma, chondroblastoma, eosinophilic granuloma and fibrous cortical defect. Our case demonstrates an uncommon occurrence in the maxillary sinus: CMF with nasal, pterygoid and orbital infiltration. In the diagnosis of an intracranial chondrocytic tumor, it is important to distinguish it from enchondroma and chondrosarcoma. MR provides a detailed assessment of soft tissue masses of the craniofacial region, while CT offers superior analysis of bone structure involvement. The present case underlines the importance of MR examination in the diagnosis of soft tissue masses in the craniofacial region.

Abstract Background Small soft tissue masses are often falsely assumed to be benign and resected with failure to achieve tumor-free margins. Therefore, this study retrospectively investigated the distribution of histopathologic diagnosis to be encountered in small soft tissue tumors (≤ 5 cm) in a large series of a tertiary referral center. Methods Patients with a soft tissue mass (STM) with a maximum diameter of 5 cm presenting at our institution over a period of 10 years, who had undergone preoperative Magnetic resonance imaging and consequent biopsy or/and surgical resection, were included in this study. A final histopathological diagnosis was available in all cases. The maximum tumor diameter was determined on MR images by one radiologist. Moreover, tumor localization (head/neck, trunk, upper extremity, lower extremity, hand, foot) and depth (superficial / deep to fascia) were assessed. Results In total, histopathologic results and MR images of 1753 patients were reviewed. Eight hundred seventy patients (49.63%) showed a STM ≤ 5 cm and were therefore included in this study (46.79 +/− 18.08 years, 464 women). Mean maximum diameter of the assessed STMs was 2.88 cm. Of 870 analyzed lesions ≤ 5 cm, 170 (19.54%) were classified as superficial and 700 (80.46%) as deep. The malignancy rate of all lesions ≤ 5 cm was at 22.41% (superficial: 23.53% / deep: 22.14%). The malignancy rate dropped to 16.49% (20.79% / 15.32%) when assessing lesions ≤ 3 cm (p = 0.007) and to 15.0% (18.18% / 13.79%) when assessing lesions ≤ 2 cm (p = 0.006). Overall, lipoma was the most common benign lesion of superficial STMs (29.41%) and tenosynovial giant cell tumor was the most common benign lesion of deep STMs (23.29%). Undifferentiated pleomorphic sarcoma was the most common malignant diagnosis among both, superficial (5.29%) and deep (3.57%) STMs. Conclusions The rate of malignancy decreased significantly with tumor size in both, superficial and deep STMs. The distribution of entities was different between superficial and deep STMs, yet there was no significant difference found in the malignancy rate.

The Masses

Soft-tissue sarcomas (STS) are a rare subtype of soft-tissue mass and are frequently misinterpreted as benign lesions. Magnetic resonance imaging (MRI) is the primary recommended type of diagnostics. To assess the quality of primary radiology reports, we investigated whether recommended MRI report elements were included in compliance with European Society of Musculoskeletal Radiology (ESSR) guidelines. A total of 1107 patients were evaluated retrospectively, and 126 radiological reports on patients with malignant STS were assessed for ESSR quality criteria. One or more required sequences or planes were missing in 67% of the reports. In all 126 cases, the report recognized the mass as anomalous (100%). Sixty-eight percent of the reports mentioned signs of malignancy. The majority of reports (n = 109, 87%) articulated a suspected diagnosis, 32 of which showed a mismatch with the final diagnosis (25%). Thirty-two percent of the reports had a misinterpretation of the masses as benign. Benign misinterpretations were more common in masses smaller than 5 cm (65% vs. 27%). Thirty percent of the reports suggested tissue biopsy and 6% recommended referral to a sarcoma center. MRI reports showed frequent deviations from ESSR guidelines, and protocol guidelines were not routinely met. Deviations from standard protocol and reporting guidelines could put patients at risk for inadequate therapy.

Aim. To assess the results of distal pancreatectomy for malignant and benign tumors and chronic pancreatitis complications. Materials and methods. Forty-seven patients, who underwent distal pancreatectomy, were under observation during the period from 01.01.2008 to 28.02.2019. Results. The long-term results of surgical treatment demonstrated the following complications: pancreatic fistulas – 15 % of observations, pancreatogenic diabetes mellitus – 12.7 %, subphrenic abscesses – 10 %. In the long-term period after the surgery – from 10 years and not less than one year – 30 patients were followed up, constituting 63.8 % of the total number. Conclusions. To prevent complications in the form of pancreatic fistula with pathological Wirsung duct dilatation more than 4–5 mm in diameter, it is necessary to form anastomosis between the pancreatic stump and the small bowel.

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.
