| Carcinoma, Hepatocellular A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested. | 0 | 2.96 | 4 | 0 |

| Parkinson Disease A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.

| Nasopharyngeal Carcinoma A carcinoma that originates in the EPITHELIUM of the NASOPHARYNX and includes four subtypes: keratinizing squamous cell, non-keratinizing, basaloid squamous cell, and PAPILLARY ADENOCARCINOMA. It is most prevalent in Southeast Asian populations and is associated with EPSTEIN-BARR VIRUS INFECTIONS. Somatic mutations associated with this cancer have been identified in NPCR, BAP1, UBAP1, ERBB2, ERBB3, MLL2, PIK3CA, KRAS, NRAS, and ARID1A genes. | 0 | 2.48 | 2 | 0 |

The majority are well differentiated vascular tumors which grow slowly and have a low potential to be invasive, although malignant subtypes occur. Meningiomas have a predilection to arise from the parasagittal region, cerebral convexity, sphenoidal ridge, olfactory groove, and SPINAL CANAL.

| Soft Tissue Infections Infections of non-skeletal tissue, i.e., exclusive of bone, ligaments, cartilage, and fibrous tissue. The concept is usually referred to as skin and soft tissue infections and usually subcutaneous and muscle tissue are involved. The predisposing factors in anaerobic infections are trauma, ischemia, and surgery. The organisms often derive from the fecal or oral flora, particularly in wounds associated with intestinal surgery, decubitus ulcer, and human bites.
