Soft Tissue Masses

Introduction. Epidermoid inclusion cysts are usually composed of epidermal elements implanted into the dermal layers. Patients are seen in the outpatient clinics with a mass. Most of the complaints are mechanical and cosmetic problems. Case Outline. A 34-year-old female patient was admitted to our clinic because of swelling and pain in her right foot. A palpable mass was detected in the first web. On the x-rays of the foot no osseous lesion was detected. There was a soft tissue mass in the first web according to MRI report. Soft tissue mass was excised and sent to pathology. According to pathology report the mass was an epidermoid cyst 5?2?1.5 cm in size. There were no problems during follow-up of the patient for 6 months after surgery. The patient had no swelling in the foot and had no additional complaints on checkup. Conclusion. In the differential diagnosis, we should take into consideration epidermoid cyst of large soft tissue masses of the foot. Surgical excision should be done within the appropriate limits.

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.

Soft Tissue Masses

Lipoblastomas and liposarcomas are rare causes of soft tissue masses in paediatric patients. In this retrospective clinical case series we identified 11 patients from our paediatric database (10 with a lipoblastoma and one with a liposarcoma) who had attended our hospital between 1998 and 2019. The median age of patients with lipoblastoma was 29 months. All lipoblastoma cases were managed with surgical excision and histological examination. The 18-year old patient with liposarcoma presented with a metastatic and unresectable tumour that was unresponsive to chemotherapy and radiation. Our experience demonstrates the importance of differentiating the type of soft tissue mass in children.

Clinical Presentations

Dialysis-related amyloidosis (DRA) is a specific subtype of amyloidosis with several clinical presentations. Herein we report a case of severe destructive tendinopathy around the wrist associated with long-standing hemodialysis (HD). A 63-year-old female patient who had been on regular HD for 23 years suffered from symptoms of pain and a palpable mass around the wrist. Magnetic resonance imaging showed an ill-defined soft tissue mass around the extensor tendons that partially invaded the wrist joint. We performed surgical excision and tenolysis for the mass. The operative finding revealed an ill-defined yellowish soft tissue mass extensively invading the extensor tendons and wrist joint. The tendon fibers were severely fibrillated and showed impending rupture due to the infiltrated mass. Histological examination showed DRA. Amyloidosis-induced tendinopathy should be considered when a patient on long-term HD complains of an unusual mass-like lesion in the extremity and/or nonspecific joint stiffness. Early surgical intervention improves patient’s disability and decreases the risk of spontaneous tendon rupture.

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.

Atypical Localization

Musculoskeletal system is rarely involved by hydatid cyst, the larvalform of Echinococcus granulosus. Two cases of intramuscular hydatid cysts within thigh musculature are being reported with the intent of highlighting this atypical localization of the disease. Preoperative computerized tomography suggested an unusual location of echinococcus. Since the soft tissue tumors may be confused with hydatid cysts, preoperative evaluation of these patients is critical for proper handling during surgery to avoid life-threatening complications. Surgical excision with postoperative antihelmenthics formed the main modality. These cases emphasize that especially in endemic areas to avoid fine-needle biopsy and the risk of spillage of cyst contents hydatidosis should be included in differential diagnosis of any soft tissue mass.

Objective: To determine whether the location of a small, indeterminate soft tissue mass within the subcutaneous compartment is related to its histological grade. Methods: All Sarcoma Service referrals over a 12 month period of small (<3 cm) superficial soft tissue masses, indeterminate by MRI evaluation which subsequently underwent primary excision biopsy were included. Lesions were categorised by their anatomical location in the subcutaneous compartment. Histopathological diagnoses were categorized according to 12 WHO 2013. χ2 statistical analysis was performed to determine the relationship between lesion depth and histological grade. Results: The study included 43 patients, mean age 42 years (range 15–71 years). Within the subcutaneous compartment, 16 lesions were categorized as superficial, 9 lesions central and 18 lesions deep, of which 9 were non-neoplastic, 29 benign, 1 intermediate-grade and 4 malignant. Location in the deep aspect of the subcutaneous compartment was associated with a higher risk of intermediate or malignant histology (p = 0.02). Conclusion: The location of a small, indeterminate soft tissue mass within the subcutaneous compartment may be an indicator of histological aggressiveness. Lesions in the deep subcutaneous compartment are more likely to be intermediate-grade/malignant lesions. Therefore, if considering excision biopsy as definitive treatment, a wider margin may be appropriate. Advances in knowledge: Small, indeterminate soft tissue masses can be aggressive and the anatomical depth within the subcutaneous tissue may be a potential indicator of histological aggressiveness.

Background: Bursitis is a chronic inflammatory condition characterized by the deposition of cholesterol, macrophage infiltration, and bursal wall calcification. Bursitis is, however, rarely found in the sacrococcygeal region where it may present as a space-occupying mass. Case Description: A 64-year-old male with rheumatoid arthritis presented with 3 years’ duration of difficulty sitting and walking due to a soft-tissue mass involving the coccyx region. Once the patient’s MR demonstrated a cystic lesion with erosion of the coccyx, the patient underwent gross total resection of the lesion that proved to be pathologically consistent with bursitis. Postoperatively, the patient’s complaints fully resolved. Conclusion: Bursitis may present as a soft-tissue tumor-like lesion in the coccyx that favorably responds to gross total surgical excision.

Current Case

The current case is one of the rare clinical presentations of the brachial artery pseudo aneurysm presentation in children Pseudo-aneurism is one of the late complications of a missed or untreated arterial injury. The diagnosis is suggested in the presence of clinical signs such as: an expending, ill-defined mass with or without pulsation; bruit, pain, paresthesia, or paralysis due to nerve compression. Although plain X-Rays may show a nonspecific soft tissue mass, arteriography is essential in defining differentiating pseudo aneurisms from other soft masses. We report a case of a 10years old boy with a history of a stab injury in a well vascularized left cubital fossa region. The physical examination revealed a soft tissue mass with eroded skin. Ultrasound and MRI findings were respectively of an infected soft tissue mass and probable malignant soft tissue mass. Open biopsy was planned but surgical finding revealed a pseudo aneurism of the left brachial artery before its bifurcation. Brachial arterial lesion was repaired blood flow reestablished with clinical improvement.

An 11-year-old cat presented for evaluation of intermittent vomiting, constipation and hyporexia of 3 weeks duration. Ultrasonographic and endoscopic examination revealed a soft tissue mass adjacent to the lower gastro-esophageal sphincter. Surgical excision of the mass was successfully performed resulting in a resolution of clinical signs. Histologically the mass was consistent with a smooth muscle hamartoma. At follow-up 7 months after surgery, the cat remained free from clinical signs.

Large Cell Lymphoma

Anaplastic large cell lymphoma (ALCL) is a T-cell lymphoma which has been recognized to have a variable clinical presentation and a broad spectrum of histomorphologic features. Its variable histomorphologic appearances are sometimes diagnostically challenging for the pathologists since they can mimic sarcomas, melanomas and undifferentiated carcinomas. To our knowledge, a previous case of axillary soft-tissue mass of ALK-positive ALCL with an alveolar growth pattern has been so far reported in the literature. This alveolar appearance is unusual for ALCL. It can impose a diagnostic pitfall, particularly in extranodal soft-tissue masses. We report a case of ALK-negative ALCL that presented as an extranodal soft-tissue neck mass in an adult man. Histologically, it showed a characteristic alveolar growth pattern composed of well-defined nests of dyscohesive highly pleomorphic large neoplastic cells separated by thin fibrovascular septae. Morphologically, it mimicked sarcomas, carcinomas, melanoma and germ cell neoplasms. Initially, a histologic diagnosis of ALCL was not considered. However, the negative immunomarkers for the above mimickers and the strong CD30 positivity have raised the suspicion of anaplastic lymphomas. Further immunohistochemistry studies showed the neoplastic cells to be positive for CD4 and CD43. This case report emphasizes the potential diagnostic pitfalls associated with an ALK-negative ALCL when manifests as a soft-tissue mass with an alveolar growth pattern. Pathologists should be aware of this uncommon growth pattern in ALCLs. They should implement a broad panel of immunomarkers in soft-tissue masses of anaplastic pleomorphic cells with an alveolar morphology.
