Primary extraskeletal osteosarcoma (EOS) is an extremely rare malignancy. In this report, the clinical course of a 32-year-old man presenting with proptoses is described. Medical history included Hirschsprung disease (HD), horseshoe kidney, azoospermia, and vertebral anomalies. Imaging of the orbit showed an oval, well-defined heterogeneous mass adjacent to the lateral wall of the orbit. The patient underwent a lateral orbitotomy and complete excision of the mass. The mass was not attached to the bone. Histopathologic and immunohistochemical examination confirmed the diagnosis of an EOS...

Extraskeletal osteosarcoma is a very rare tumor in humans and animals. This paper describes a case of extraskeletal osteosarcoma observed in the duodenum of a male ICR mouse. Grossly, a solid mass pushing up the tunica serosa was observed in the duodenal wall. Histologically, the tumor was located in the lamina propria mucosae and tela mucosa. Neoplastic cells densely proliferated in these areas, and replaced of the normal tissue components. A small amount of osteoid and a small clump of bone tissue were observed in the area of neoplastic cell proliferation, especially in the lamina propria mucosae...

Giant cell-rich osteosarcoma is a rare histologic variant of conventional osteosarcoma that affects mainly the extremities. Extraskeletal giant cell-rich osteosarcoma is therefore exceedingly rare. Here, we report the first case of this uncommon tumor involving the parotid gland in a 62-year-old male who presented with initial right jaw swelling. Radiologic work-up revealed a 6.2 cm mass involving the right parotid gland. Fine-needle aspiration cytology showed numerous multinucleated giant cells in a background of dyshesive epithelioid cells and rare clusters of spindle stromal cells, suspicious for malignancy...

BACKGROUND Extraskeletal osteosarcomas (ESOS) of the mediastinum are extremely rare and may present with concurrent nontuberculous mycobacteria infection. CASE REPORT We present the second documented case of high-grade anterior mediastinal extraskeletal osteosarcoma in a 59-year-old man with a history of treated, latent tuberculosis (TB). Sputum samples grew Mycoplasma avium complex and Mycobacterium fortuitum. Imaging showed a right-sided 7.6 cm mass with compression of the main bronchus. Subsequent biopsy with vimentin staining established the diagnosis of ESOS...

Extraskeletal osteosarcoma (ESOSA) is a rare soft tissue neoplasm representing <5% of osteosarcomas and <1% of all soft-tissue sarcomas. Herein, we investigate the clinicopathological and molecular features of ESOSA and explore potential parameters that may affect outcome. Thirty-two cases were retrieved and histomorphology was reviewed. Clinical history and follow-up were obtained through electronic record review. DNA from formalin-fixed paraffin-embedded (FFPE) tissue was extracted and processed from 27 cases...

A 69-year-old female with a history of a heart transplant 16 years prior, presented with a large left chest mass identified on fluoroscopy in the cardiac catheterization lab. The patient noted a 40 pound weight loss in one year. A chest X-ray (CXR) and chest computed tomography (CT) demonstrated a large complex cystic mass in the left chest. A CT guided aspiration was performed, and the cytology for the cyst fluid was negative for malignancy. The patient continued to have worsening shortness of breath, a repeat chest CT scan and magnetic resonance imaging (MRI) three months later, demonstrated a recurrence of the left pleural mass...

Extraskeletal osteosarcoma (ESOS) originating in the subcutaneous tissue is a rare occurrence, accounting for less than 10 % of ESOS cases. Osteosarcoma of extraskeletal origin accounts for approximately 2-4 % of all osteosarcomas, and 1 % of soft tissue sarcomas. We report a case of an 80-year-old female with an isolated primary subcutaneous tumor of the forearm. After imaging, surgical excision, and pathological analysis, the diagnosis of a subcutaneous osteosarcoma was made. This report documents the clinical and pathological findings of subcutaneous ESOS in this case, along with a review of previous cases of subcutaneous ESOS...

Chondral tumors in soft tissue are referred to as soft-tissue chondromas or extraskeletal chondromas, or as synovial chondromatosis if they arise in synovial tissue. We report the case of a 29-year-old man with synovial chondromatosis, also called synovial osteochondromatosis, which appeared in a solitary and extra-articular form. On magnetic resonance imaging (MRI) and computed tomography, the central portion of the tumor showed similar characteristics to bone marrow, despite the absence of any connection to adjacent bone...

Extraskeletal osteosarcoma is extremely rare in mice. This case report demonstrates a spontaneous murine extraskeletal osteosarcoma that exhibited various histological growth patterns in an ICR mouse. At necropsy, the tumor mass was located in the abdominal wall and was 45 × 30 × 25 mm in size. Histopathologically, the tumor showed the following four growth patterns: a solid pattern of polygonal cells embedded in an osteoid eosinophilic matrix with calcification, an irregular sheet pattern of short spindle cells accompanying some eosinophilic multinucleated cells, a fascicular pattern of spindle cells and a cystic pattern lined by short spindle cells...

Osteosarcoma is the most common primary malignant bone tumour with a bimodal peak. But its extraskeletal variant is very rare. It arises exclusively in soft tissue without at any skeletal attachment. It accounts for 2% of all soft tissue sarcomas. It is usually diagnosed as an incidental finding during imaging. Here, we are presenting a case of extraskeletal osteosarcoma diagnosed incidentally during imaging in a 30 years old male for its rarity.

Primary extraskeletal osteosarcoma is an exceedingly rare malignant neoplasm that accounts for approximately 1% of soft tissue sarcomas and most often occurs in the deep soft tissues of adults. Extraskeletal osteosarcoma is characterized by the production of osteoid, bone, and/or chondroid matrix. The diagnosis of extraskeletal osteosarcoma requires careful radiologic and clinical correlation to ensure that the patient does not have an underlying bone primary. This is a case report of primary subcutaneous extraskeletal osteosarcoma arising in the thigh of a 15-year-old girl with a complex karyotype, and the morphologic differential diagnosis is reviewed...

An 8 yr old spayed female Italian greyhound was presented with a mass in the cranial abdomen. Preliminary evaluation of the dog revealed a large, cavitary, irregularly shaped mass with no definitive association with any abdominal organs. During an exploratory celiotomy, a 16 cm × 12 cm × 6 cm mass was removed. On subsequent histopathology, extraskeletal osteosarcoma induced by a foreign body granuloma was diagnosed. The foreign body granuloma, based on histopathological findings, was suspected to be secondary to a retained surgical sponge from her routine ovariohysterectomy performed 7 yr prior to presentation...

For the first time extraskeletal osteosarcomas (ESOS) were described by Wilson in 1941. They are extremely rare neoplasms, presenting 4% of all osteosarcomas and 1,2% of all soft-tissue sarcomas. About 300 cases have been reported in the literature up to date. We present a 66-year-old female patient, admitted in the clinic because of acute bleeding in retroperitoneal space. Revision of the retroperitoneal space and haemostasis were performed. The patient was re-operated because postoperative bowel obstruction...
