BackgroundMyeloid sarcoma is a rare extramedullary tumour of immature granulocytes, most commonly involving the skin, bone, lymph nodes, and soft tissue. It usually associated with diagnosis relapsed or de novo acute myeloid leukaemia, lymphoblastic transformation myelodysplastic/myeloproliferative neoplasm, can occur as isolated sarcoma.Case reportA 66-year-old female 7-year history stable chr...

Primary sternal osteomyelitis is a rare condition. Only few cases have been reported in the English literature. We describe the case of a young woman presenting with persistent fever and chest pain. Radionuclide bone scan and computed tomography of the chest were consistent with metastatic neoplasm. Surgical intervention, however, revealed primary staphylococcal osteomyelitis and the patient wa...

Dermatofibrosarcoma protuberans (DFSP) is a rare, low-grade, cutaneous neoplasm with pronounced tendency for local recurrence. A case of DFSP that showed direct infiltration into the underlying bone marrow is described. To the best of our knowledge, such direct bony involvement by dermatofibrosarcoma has not been reported in the English literature to date. The role of imaging is also discussed ...

Intraosseous cavernomas are very rare benign lesions representing less than 1% of all skeletal tumors and most frequently observed in vertebrae and head and neck bones. Solitary hemangiomas of the hand bones are exceptionally rare. We report a case of this neoplasm in the distal epiphysis of the third metacarpal bone in a 68-year-old man, along with the clinicopathological findings. The differe...

Here, we describe two cases of lung metastasis of adamantinoma of long bones, a low-grade bone neoplasm that rarely metastasizes. In both cases, the clinical presentation of the metastases was characterized by spontaneous pneumothorax secondary to tumor cavitation, a phenomenon described in only three of the studies reviewed in the literature. Clinical, radiological, and anatomopathological fin...

Hemangiomas of the rib are extremely rare benign neoplasm. Here we present a case in a 47-year-old female, detected by chest X-ray and underwent a surgical resection. Histologically, the tumor was composed of a homogeneous conglomerate, irregular, thin walled and dilated blood vessels containing red blood cells, supported by fibrous stroma and intermingled to regular bone trabeculae. The postop...

Extraskeletal osteosarcoma (ESOS) is a rare soft tissue sarcoma, typically characterized by a bone-producing neoplasm. Low-grade extraskeletal osteosarcoma (LGESOS) is an extremely rare soft tissue tumor, and patients with LGESOS tend to have a better prognosis. Here, we reported a case of LGESOS of the mediastinum with lung metastasis, and describe its clinical, pathological and radiological f...

Splenic lymphoma with circulating villous lymphocytes (SLVL) is an indolent B-cell neoplasm. Because of its rarity, a definitive diagnosis often becomes difficult. In this study we are going to discuss about two cases of SLVL. Despite being a variant of lymphoma peripheral lymphadenopathy is not found in such cases. Careful analysis of blood or bone marrow sample by flow cytometry may be helpfu...

Prenatal ultrasonography at 24 weeks disclosed a fetus with a large mass protruding from the occiput. The mass was an invasive, undifferentiated mesenchymal neoplasm of the scalp associated with a defect in the occipital bone (cranium bifidum). The tumor may have derived from neural crest at the site of rhombencephalic closure. The tumor itself would seem to be a sporadic event, but the cranium...

Juvenile ossifying fibroma (JOF) is a benign, bone-forming neoplasm occurring primarily in children and adolescents. JOF is an aggressive variant of ossifying fibroma of the jaw with a variable clinical behavior and a high tendency for recurrence. Early detection and prompt treatment are required to treat JOF successfully. This case report describes JOF in a 13-year-old girl presenting with a y...
