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.

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.

Soft Tissue Masses

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.

A 15-y-old castrated male Maine Coon cat was evaluated for an ulcerated soft tissue mass on the right hindlimb that had been observed for 4 mo and had grown rapidly. A 3 × 3 cm soft, raised, amorphous, and ulcerated subcutaneous mass was observed on the lateral right metatarsus. In-house cytology via fine-needle aspiration was nondiagnostic. Incisional biopsy of the mass and further staging was declined, and amputation was elected. The amputated limb was submitted for histopathology, which revealed severe chronic nodular granulomatous dermatitis and multifocal granulomatous popliteal lymphadenitis with large numbers of intralesional fungal hyphae. Fungal PCR and sequencing on formalin-fixed, paraffin-embedded tissue identified Chalastospora gossypii. No adjunctive therapy was elected at the time. The patient has done well clinically 1 y post-operatively. C. gossypii is a rare microfungus found worldwide and is considered a minor pathogen of several plants. To our knowledge, infection by this fungus has not been reported previously in veterinary species. Features in our case are comparable to other mycotic infections. Nodular granulomatous mycotic dermatitis and cellulitis, although uncommon, should be a differential for soft tissue masses in veterinary species; C. gossypii is a novel isolate.

Purpose: To evaluate the capability of color Doppler ultrasonography to differentiate between benign and malignant soft-tissue tumors. Material and Methods: We reviewed the ultrasonographic (US) and color Doppler (CD) findings in 46 consecutive patients with a palpable periskeletal mass. The presence of 3 or more vascular hila and of tortuous and irregular internal vessels within the lesions was considered an indication of malignancy. The CD diagnosis was compared with that obtained at US alone. Results: The sensitivity and specificity of CD were respectively 85% and 92%; these values were higher than those obtained at US alone, respectively 75% and 50%. Arteriovenous malformations presented as lesions with large internal vessels that had low vascular impedance and were easily diagnosed. The waveform patterns within solid tumors were not specific. Conclusion: At present, US is commonly employed to confirm the presence of a suspected soft-tissue mass, to locate it accurately, and to indicate its nature. CD findings enhance the role of the US technique in such lesions. The combined use of US and CD can allow the differentiation of benign from malignant lesions, and thus provide a better basis for treatment.

Soft tissue masses are amongst the commonest complaints encountered in orthopedic practice. Of these, masses found in the hand and the wrist are presented at higher frequency. They are often painful and may cause limitation of movement. This work describes the prevalence and the nature of soft tissue masses in the hand and wrist encountered in routine practice. This work was performed to assess the characteristics of soft tissue mass in the hand and the effectiveness of ultrasonography in the diagnosis of soft tissue masses and their differentiation from other lesions in the hand and wrist. Orthopedic surgical conditions that involve soft tissue in the hand and wrist may remain a diagnostic challenge when clinical diagnosis is uncertain and standard X-rays are non-diagnostic. High resolution ultrasound is widely available, non-invasive, without damage of radiation, imaging modality that can help the diagnosis. We reviewed retrospectively 25 patients with soft tissue masses. We compared the ultrasound findings with the histological findings in seven operated patients. A substantial majority of these lesions occurred in the right hand: 79% of the lesions were in the dorsal aspect of the hand, of which 37% were distal to the wrist joint, among them 42% at wrist either radial or ulnar; and 21% of the lesions were found in the volar aspect, among them 17% at wrist aspect, either radial or ulnar side. No predisposing factors could be found. The findings of this study reaffirm the utility of ultrasonography as primary diagnostic tool in routine orthopedic practice.

AbstractHere, the authors describe a case of 25-year-old man diagnosed with dural plasmacytoma involving calvarium with soft tissue extension. Magnetic resonance imaging (MRI) revealed extra-axial heterogeneously enhancing soft tissue mass lesion in the left parieto-occipital region with a dural tail mimicking meningioma, destroying the left parietal bone, and bulging into the scalp. Mass was excised and histopathologic examination revealed plasmacytoma with amyloid deposition. There is no recurrence after postoperative radiotherapy and 2 years of follow-up, although the future course is still not certain. The clinician should consider alternative diagnosis other than meningioma prior to proceeding to surgery if the dural-based lesion is involving calvarium and soft tissue extension.

AbstractThe vast majority of soft tissue masses are benign. Benign lesions such as superficial lipomas and ganglia are by far the most common soft tissue masses and can be readily identified and excluded on ultrasound (US). US is an ideal triaging tool for superficial soft tissue masses. Compared with magnetic resonance imaging (MRI), High-resolution US is inexpensive, readily available, well tolerated, and safe. It also allows the radiologist to interact with the patient as a clinician. In this review, we describe and illustrate the lesions with typical (diagnostic) US features. When the appearances of the lesion are not typical as expected for a benign lesion, lesions are deep or large, or malignancy is suspected clinically, MRI and biopsy are needed. The management of suspicious soft tissue tumors has to be carefully planned by a multidisciplinary team involving specialized surgeons and pathologists at a tumor center.

Objective: This study aimed to compare the differences in the clinical features of prostate cancer (PC) bone metastases (PCBMs) with and without extraosseous soft-tissue masses (ESTMs). Methods: Among 720 consecutive patients with histopathologically or clinically diagnosed PC, PCBMs were identified in 48 (7%) patients at initial diagnosis before receiving treatment. CT images of PCBMs were assessed and classified into two groups: PCBMs with and without ESTMs. Clinical features of PCBMs with and without ESTMs were compared. Results: We found ESTMs in 15 (31%) patients diagnosed with PCBMs, and 33 (69%) patients diagnosed with PCBMs did not have ESTMs. The initial prostate-specific antigen (PSA) levels (median, 1031 vs 247 ng ml−1; p < 0.05) and PSA reduction rates (median, 99.97 vs 99.40 %; p < 0.05) were significantly greater in PCBMs with ESTMs than in PCBMs without ESTMs. No significant differences were observed in terms of age, Gleason sum score, PSA nadir, time from the initiation of therapy to PSA nadir, PSA doubling time, PSA progression-free survival, or overall survival between patients having PCBMs with and without ESTMs. Conclusion: Both initial PSA levels and PSA reduction rates were higher in PCBMs with ESTMs than in PCBMs without ESTMs; however, no significant differences were observed in other clinical features. Advances in knowledge: ESTMs in patients with PCBMs were not a poor prognostic factor.

Soft Tissue Masses

The paratestis (PT) is defined by the testicular tunics, epididymis, spermatic cord, rete testis, and embryonic remnants. It gives rise to a large diversity of pathologies, including those of soft tissue, which may prompt orchiectomy. We performed a 17-year search of our database for orchiectomies for a PT soft-tissue mass. In a total of 4741 orchiectomy specimens, 138 orchiectomies were performed for primary neoplastic or nonneoplastic masses of the PT soft tissue or had an incidental PT soft-tissue mass. Of these, 65.9% were neoplastic. The mean age was 40.2 years (range: <1 to 87 years) and was similar for neoplastic and nonneoplastic lesions. The most common malignancies were rhabdomyosarcoma (31/63 malignancies), liposarcoma (19/63), and leiomyosarcoma (5/63), with the former occurring in younger patients (average: 18.3 years). No malignancies were incidental. The most common benign neoplasm was spermatic cord lipoma (24/28 of benign neoplasms); however, most were incidental. This was followed by leiomyoma (3/28) and hemangioma (1/28). The most common nonneoplastic lesions were adrenal rests (22/47 nonneoplastic cases); however, all were incidental findings. Of 47 nonneoplastic masses, 22 prompted orchiectomy, and of these, the most common diagnosis was fibrous/nodular periorchitis (11/47). Of 88 nonincidental lesions, 25 were either benign neoplasms (3/25) or nonneoplastic (22/25). These data indicate that PT soft-tissue neoplasms prompting orchiectomy are disproportionately rhabdomyosarcomas, though these are principally in young patients. In older patients, malignancies are more frequently liposarcomas. However, almost one-third of orchiectomies performed for PT soft-tissue masses yield benign lesions, indicating an opportunity to reduce unnecessary procedures.
