Pulmonary sclerosing (Pneumocytoma) is a rare benign pulmonary tumor of primitive epithelial origin. Because of the unspecific radiological features mimicking malignancies and their histological heterogeneity, the differential diagnosis with adenocarcinoma and carcinoid tumors is still challenging.

Pancreatic diseases is very multiform and complex, in which pancreatic tumors have often poor prognosis, especially pancreatic cancer. Early detection and diagnosis of pancreatic tumors have great significance in improving the quality of treatment and prognosis for patients. Endoscopic ultrasound has the advantage of high-frequency ultrasound, an optimal approach to provide a possibility of EUS-FNA.

The WHO Classification of Soft Tissue and Bone Tumours currently recognizes four categories of undifferentiated small round cell sarcoma: Ewing sarcoma, round cell sarcoma with EWSR1-non-ETS fusions including NFATc2 and PATZ1, CIC-rearranged sarcoma, and sarcoma with BCOR genetic alterations. These neoplasms frequently pose significant diagnostic challenges due to rarity and overlapping morphologic and immunohistochemical findings.

Ovarian cancer constitutes one of the most lethal gynecologic malignancies for females. Currently, early detection strategies and therapeutic options for ovarian cancer are far from satisfactory, leading to high diagnosis rates at late stages and disease relapses. New avenues of therapy are needed that target key processes in ovarian cancer progression.

Breast cancer (BC), the most common type of cancer among women worldwide, is a polygenetic disease which is caused by the interaction of several genes. Understanding the genetic factors for early diagnosis of BC is crucial to ensure the survival of BC patients. MicroRNA 27a (miR-27a), an oncogenic miRNA, has been predicted to target on the tumor suppressor ZBTB10 that can regulate many processes of cell.

Autoantibodies against autologus tumor-associated antigens have been detected in the asymptomatic stage of cancer and can thus serve as biomar-kers for early cancer diagnosis. Moreover, because autoantibodies are found in sera, they can be screened easily using a noninvasive approach. Consequently, many studies have been initiated to identify novel autoanti-bodies relevant to various cancer types.

a-enolase (ENOA) is a metabolic enzyme involved in the synthesis of pyru-vate. It also acts as a plasminogen receptor and thus mediates activation of plasmin and extracellular matrix degradation. In tumor cells, EMOAis upregulated and supports anaerobic proliferation (Warburg effect), it is expressed at the cell surface, where it promotes cancer invasion

Some urinary tract disorders rarely cause symptoms until the problem is very advanced; these include kidney failure, tumors and stones that do not block urine flow, and some low-grade infections. Sometimes, symptoms occur but are very general and difficult for the doctor to connect to the kidney. For example, a general feeling of illness (malaise), loss of appetite, nausea, or generalized itching may be the only symptoms of chronic kidney failure. In older people, mental confusion may be the first recognized symptom of infection or kidney failure. ...

Evaluation of an adequate biopsy by an expert hematopathologist is sufficient to make a diagnosis of follicular lymphoma. The tumor is composed of small cleaved and large cells in varying proportions organized in a follicular pattern of growth (Fig. 105-7). Confirmation of B cell immunophenotype and the existence of the t(14;18) and abnormal expression of BCL-2 protein are confirmatory. The major differential diagnosis is between lymphoma and reactive follicular hyperplasia. The coexistence of diffuse large B cell lymphoma must be considered.

This marrow section shows the marrow cavity replaced by fibrous tissue composed of reticulin fibers and collagen. When this fibrosis is due to a primary hematologic process, it is called myelofibrosis. When the fibrosis is secondary to a tumor or a granulomatous process, it is called myelophthisis. Diagnosis While the clinical picture described above is characteristic of chronic IMF, all of the clinical features described can also be observed in PV or CML.

Pure Red Cell Aplasia: Treatment History, physical examination, and routine laboratory studies may disclose an underlying disease or a suspect drug exposure. Thymoma should be sought by radiographic procedures. Tumor excision is indicated, but anemia does not necessarily improve with surgery. The diagnosis of parvovirus infection requires detection of viral DNA sequences in the blood (IgG and IgM antibodies are commonly absent). The presence of erythroid colonies has been considered predictive of response to immunosuppressive therapy in idiopathic PRCA.

Clinical Manifestations Patients with cancer who develop deep venous thrombosis usually develop swelling or pain in the leg, and physical examination reveals tenderness, warmth, and redness. Patients who present with pulmonary embolism develop dyspnea, chest pain, and syncope, and physical examination shows tachycardia, cyanosis, and hypotension. Some 5% of patients with no history of cancer who have a diagnosis of deep venous thrombosis or pulmonary embolism will have a diagnosis of cancer within 1 year.
