although aneurysmal bone cysts and calcifying odontogenic cysts accompanied with other lesions are reported in the literature, the simultaneous occurrence of these two distinct lesions has not been reported. to the best of our knowledge, this is the first report describing co-occurrence of these two lesions located in the left mandibular ramusin a 36-year-old woman.

osteoblastoma is a rare benign, but locally aggressive bone tumor with rare malignant transformation. it mostly affects the vertebral column and long bones. radiographically, it is seen as an expansile, oval, sclerotic or lytic mass-like lesion with well-defined borders, although sometimes it may mimic a malignant tumor such as osteogenic sarcoma by its irregular borders. herein, we report a ca...

Background: Bone marrow is the site of many malignant disorders and it is one of the common places for solid tumors to metastasize. Examination of the bone marrow aspirate and biopsy is a routine procedure performed for assessment of various conditions such as cytopenias, hematologic neoplasms, nonmalignant disorders and metastatic neoplasms. Methods: The patients were referred to the Hema...

hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. we report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. although computed tomography (ct) and magnetic resonance imaging (mri) showed several enhanci...

Osteosarcoma is the most frequent malignant bone neoplasm, followed by chondrosarcoma and Ewing sarcoma. The diagnosis of bone neoplasms is generally made through histological evaluation of a biopsy. Clinical and radiological features are also important in aiding diagnosis and to complete the staging of bone cancer. In addition to these, there are several non-specific serological or specific mo...

Mastocytosis is one of eight subcategories neoplasms. Classification Myeloproliferative Tumors Lymphoid Tissues and hematopoietics 2008 the World Health Organization; a heterogeneous group myeloproliferative diseases that distinguished by excessive proliferation mast cells morphologically immunophenotypically atypical, in addition to accumulation these or more organs tissues, including skin, bo...

Plasma cell neoplasms are characterized by a neoplastic plasma cell lineage which produces a monoclonal immunoglobulin. These neoplasms can present as a single lesion (solitary plasmacytoma) or as multiple lesions (multiple myeloma). Solitary plasmacytomas most frequently occur in bone (plasmacytomas of bone), but can also be found outside bone in soft tissues (extramedullary plasmacytomas).

Thrombocytopenia is a common manifestation of tumors, which usually caused by myelosuppression bone marrow involvement malignant tumor cells or radiotherapy. Immune thrombocytopenia (ITP), as paraneoplastic syndrome, more in lymphatic proliferative neoplasms and rheumatic diseases, less solid neoplasms, has not been reported peritoneal epithelioid mesothelioma.Herein, we report 45-year-old pati...

A diagnostic approach of myeloproliferative neoplasms, according to the 2008 WHO classification system for hematological malignancies, has to consider clinical, molecular, and cytogenetic information as well as bone marrow histology. A diagnosis of chronic myeloid leukemia requires the presence of BCR-ABL-1, and the Philadelphia chromosome-negative (Ph-1-negative) myeloproliferative neoplasms c...

Bone marrow fibrosis leading to dry tap aspiration and often associated with blast crisis has previously been reported in both Chronic myeloid leukemia Primary myelofibrosis. The similarities between these two conditions terms of clinical presentation morphology can really create a diagnostic dilemma. Here we present case 32 year old lady which closely resembled myelofibrosis transformation. Al...
