We present the particular clinical and histological features of a metastatic high-grade myxofibrosarcoma (MFS) of the left buttock in a 77-year-old male patient. The tumor was biopsied and surgically removed in order to increase the patient's comfort, due to its increased size and aggressive clinical behavior. Computed tomography (CT) revealed metastases in the pleura and mediastinal lymph nodes, so limb-sparing tumor excision followed by palliative care was the best practice for the patient until the fatal outcome...

Pleomorphic undifferentiated sarcoma (PUS), also called malignant fibrous histiocytoma, is a soft tissue sarcoma which occurs predominantly in the extremities. Its origin is a poorly defined mesenchymal cell, which derives to histiocytic and fibroblastic cells. The patient, a 58 year-old man, presented a lesion located in the forearm composed by spindle cells and multinucleated giant cells, which expressed vimentin and adopted a histological pattern formed by irregular-swirling fascicles. Cells were cultured in vitro and a new cell line was established...

INTRODUCTION: Soft-tissue sarcomas account for 0.7% of all malignant tumors, with an incidence rate of 3 per 100,000 persons/year. The undifferentiated pleomorphic sarcoma (UPS) with giant cells, a high grade tumor of soft tissue, is very unusual, especially in young adults before the age of 40. Human T-cell lymphotropic virus type 1 (HTLV-1) is a human retrovirus, classified as group 1 human carcinogens by The International Agency for Research on Cancer, that causes an aggressive malignancy known as adult T-cell lymphoma/leukemia and a progressive chronic inflammatory neurological disease named HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP)...

We report two cases of giant cell tumor arising from the rib and their F-18 FDG PET/CT findings. The two patients complained of chest wall pain, and large lobulated soft tissue masses with intense FDG uptake were seen on F-18 FDG PET/CT. A malignant tumor such as osteosarcoma or chondrosarcoma was suspected due to the large size of the mass, bony destruction, and intense FDG uptake. En bloc resection was performed and final pathologic results revealed giant cell tumor of the rib. Giant cell tumor of the rib is very rare, and larger lesions with high FDG uptake can be misdiagnosed as an intrathoracic malignancy arising from the rib, pleura, or chest wall...

Paget's disease of the bone may predispose the development of malignant bone tumors such as osteosarcoma. Giant cell tumor (GCT) as a consequence of Paget's disease is rare. Bone GCT is characterized by rapid growth, the destruction of bone, extension to the surrounding soft tissue and abnormal bone turnover caused by an abnormality of the receptor activator of nuclear factor-κB (RANK)-RANK ligand (RANKL) pathway. Denosumab is a RANK-RANKL inhibitor, which is used to treat osteoporosis and bone GCT. In the current study, a 60-year-old male presented with severe pain located between the right thigh and the knee...

BACKGROUND: Tenosynovial giant cell tumor (TSGCT), also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis, is the most common benign tumor of the tendon and synovium. The intra-articular diffuse type can present as a large infiltrative mass involving adjacent soft tissue and sometimes causes secondary destruction of bone, which leads to radiographic and clinical concern for malignancy. The tumor may also be purely extra-articular. CASE: Here, we report the fine needle aspiration cytology findings of 2 cases of diffuse-type TSGCT with large mononuclear cells with eccentric nuclei, finely granular cytoplasm, and a peripheral well-defined cytoplasmic rim of hemosiderin ("ladybird cells")...

We report a case of thoracic sarcoidosis in a 72-year-old female, snuff taker, who presented with multinodular pulmonary lesions on chest x-ray. Clinical and biological findings were poor. Thoracic imaging showed soft tissue density nodules with irregular borders. The diagnosis of 'cannon ball' metastases was suspected. A thorough investigation strategy could not prove malignancy. A complete radiologic clearing was obtained spontaneously within three months. A rereading of pathology slides performed afterwards showed multinucleated giant cells on hemorrhagic background with a lymphocytic alveolitis...

Primary mucinous adenocarcinomas of the salivary gland are rare malignancies defined by aggregates of epithelial cells suspended in large pools of extracellular mucin. We report a case of a giant mucinous adenocarcinoma of salivary gland origin, with low-grade cytoarchitectural features and neuroendocrine differentiation arising in the submental region. Grossly, the tumor measured 12.5 × 13.4 × 8.2 cm and replaced the bone and soft tissues of the anterior oral cavity. Microscopically, the neoplasm was composed of large extracellular pools of mucin, which contained papillary and acinar aggregates, and small nodules of ductal type epithelium with minimal nuclear enlargement, powdery chromatin and little pleomorphism...

Giant cell tumor of bone (GCTB) represents one of the commonest bone tumors encountered by an orthopedic surgeon. The giant-cell tumor is generally classified as benign but the fast growing rhythm and the aggressive soft-tissue invasion may in some cases demonstrate a malign potential of the tumor. We present the case of an aggressive giant cell tumor in a young patient that was first diagnosed in our emergency department with a fracture of the distal femur after a low energy trauma. With further examinations, we discovered that the tumor was invading the both femoral condyles and was vascularized by three major arterial pedicles...

Clear-cell sarcoma is a rare and malignant soft tissue tumor most commonly located at the distal end of extremities and rarely at the trunk. Data on the clinical features of the tumor is limited, complicating the analysis of prognosis and establishment of treatment protocols. In our study, we present a case diagnosed with clear-cell sarcoma in his right scapula and treated with tumor resection and chemotherapy, combination of dacarbazine, pharmorubicin and cisplatin. The patient died due to multiple organ failure eight months after operation...

Solitary fibrous tumors (SFTs) are uncommon spindle-cell tumors of mesenchymal origin initially described in the pleura and subsequently in other extra-pleural sites. These tumors are categorized as tumors of 'intermediate malignancy' under the World Health Organization classification of soft tissue tumors. SFT was virtually non-existent or misdiagnosed until its characteristic features, particularly the strong and diffuse immuno-reactivity to CD 34 were described. Extra-pleural manifestations of SFT, particularly in the head and neck region are rare...

A 12-year-old British Warmblood mare was examined by the referring veterinarian for evaluation of a cutaneous lesion on the dorsal thorax to the right of the midline. Cytologic examination of fine-needle aspirates from the mass was supportive of a giant cell tumor of soft parts (GCTSP). Laser surgical excision and postoperative methyl aminolevulinate (MAL) photodynamic therapy (PDT) were performed. Histologic examination of the mass confirmed the cytologic diagnosis. At 8 months from surgery, no evidence of recurrence has been observed...

Primary giant cell tumors of soft tissues (GCT-ST) are extremely rare soft tissue tumors, located in both superficial and deep soft tissues. They resemble osseous giant cell tumors morphologically and immunohistochemically. The tumor exhibits strong positive immunoreactivity for cluster of differentiation 68 (CD68) within multinucleated osteoclast-like giant cells and focal staining of mononuclear cells. Case reports describing the cytohistological features of this entity are very few. We report a case of GCT-ST of low malignant potential diagnosed on fine needle aspiration (FNA) and confirmed on histological and immunohistochemical studies...

BACKGROUND: A tenosynovial giant cell tumor (T-GCT) is a benign synovial tumor arising from the synovium, bursae, or tendon sheath. It can be intra- or extra-articular and localized or diffuse. Diffuse T-GCT is considered as a locally aggressive. Positron emission tomography (PET) with fluorine-18 fluorodeoxyglucose with computed tomography (FDG PET/CT) is widely used to differentiate malignant from benign tumors and to detect distant metastasis. However, FDG PET/CT is limited by false-positive findings...

Extraosseous giant cell tumors have been described in organs like larynx, thyroid, pancreas, heart, skin, lung, colon, kidney, and soft tissues (Wu et al., Oncol Lett 2013;6:829-832). Osteoclast-like giant cell tumor of the parotid gland has been reported only rarely with the first description of primary giant cell tumour of the parotid gland (GCTPs) given in 1984 by Eusebi et al. (Am J Clin Pathol. 1984;81:666-675). However, FNAC of osteoclast-like giant cell tumor of the parotid gland has not been well described, and only one case has been reported till date (Torabinezad et al...

Bone and soft-tissue sarcomas comprise a rare, complex, and heterogeneous group of tumors for which it is difficult for even experienced pathologists to provide a conclusive diagnosis. The number of diagnoses made using genetic analysis has increased since the detection of fusion genes in several soft-tissue tumors in the 1990s. Moreover, other specific genetic aberrations have been reported in various bone and soft-tissue tumors. In addition, molecular therapeutic targets have been sought in advanced cases of soft-tissue and bone tumors similar to other organ malignancies...
