Malignant transformation of craniopharyngioma with detailed follow-up.

A 29-year-old male patient was admitted into hospital with the main complaint of progressive visual disturbance. Both CT SCAN and MRI demonstrated a cystic-solid contrast-enhancing sellar-suprasellar mass with obvious calcification. Histopathological examination of the first resected specimen showed a typical appearance of adamantinomatous craniopharyngioma.

[Pulmonary epithelioid hemangioendothelioma: a clinicopathological analysis].

Objective: To report 3 cases of pulmonary epithelioid haemangioendothelioma (PEH) and therefore to improve the understanding of this tumor.

Methods: The clinical pathological features of 3 cases of PEH were described and related literatures were reviewed.

Results: The etiology of this rare disease remained unknown.

[Pleuropulmonary blastoma of adults: a clinicopathological analysis].

Objective: To report two cases of pleuropulmonary blastoma (PPB) of adults and improving the understanding of this tumor.

Methods: The clinicopathological features of two cases of adult PPB were examined by light microscope and an immunohistochemical study.

Results: As a rare malignant mesenchymal tumor, PPB arose from primitive cells of lung, pleura and mediastinum.

[Comparative proteomics of the serum in patients with nasopharyngeal carcinoma: a study with two-dimensional electrophoresis and MALDI-TOF-MS].

Objective: To screen the tumor specific antigens of nasopharyngeal carcinoma (NPC) in the serum of the patients.

Methods: Two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was employed to screen the specific biomarkers of NPC in the sera from 42 healthy volunteers, 37 NPC patients with lymph node metastasis and 27 NPC patients without lymphatic metastasis.

Results: After pretreatment including albumin and immunoglobulin (IgG) depletion and desalting, the sera were subjected to 2-DE and image analysis.

[Clinical and pathologic features of malignant myoepithelioma of salivary glands].

Objective: To analyze the clinical features, morphology and biologic behavior of primary malignant myoepithelioma (MME) of salivary glands.

Methods: The H&E sections of 16 MME cases were reviewed. Immunohistochemical study using EnVision method for cytokeratin (CK), epithelial membrane antigen (EMA), vimentin, S-100 protein, desmin, muscle-specific actin (MSA), smooth muscle actin (SMA), Myo, proliferation cell nuclear antigen (PCNA), leukocyte common antigen (LCA) and glial fibrillary acidic protein (GFAP) was carried out.
