C2712334
Finding
3.

Lipomatosis, multiple

Familial multiple lipomatosis is a rare autosomal dominant disorder characterized by numerous encapsulated lipomas on the trunk and extremities (Keskin et al., 2002). [from GTR]

MedGen UID:
483366
Concept ID:
C3489413

4.

Aspiration

Inspiration of a foreign object into the airway. [from HPO]

MedGen UID:
472619
Concept ID:
C0700198
Pathologic Function
5.

Pleomorphic Lipoma

A benign circumscribed tumor characterized by small spindle cells, rounded hyperchromatic cells and multinucleated giant cells with radially arranged nuclei. [from NCI]

MedGen UID:
60027
Concept ID:
C0205823
Neoplastic Process
6.

Histiocytoma

A mesenchymal tumor composed of fibroblastic and histiocytic cells. [from NCI]

MedGen UID:
267592
Concept ID:
C1509147
Neoplastic Process
7.

Pleomorphic Liposarcoma

A liposarcoma characterized by the presence of varying proportions of pleomorphic lipoblasts in a background that resembles undifferentiated pleomorphic sarcoma. It is the rarest liposarcoma variant and usually has an aggressive clinical course. [from NCI]

MedGen UID:
61457
Concept ID:
C0205825
Neoplastic Process
8.

Liposarcoma

A malignant tumor derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (LIPOSARCOMA, MYXOID), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces. (From Dorland, 27th ed; Stedman, 25th ed) [from MeSH]

MedGen UID:
44177
Concept ID:
C0023827
Neoplastic Process
9.

Slow Growing

An indication that something is growing at a slow rate. [from NCI]

MedGen UID:
894623
Concept ID:
C4086857
Finding
10.

Very Important

A subjective answer of very strong agreement regarding the importance of something. [from NCI]

MedGen UID:
854240
Concept ID:
C3844729
Finding
11.

Atypical Lipomatous Tumor

An intermediate, locally aggressive lipomatous neoplasm. Microscopically, the adipose tissue contains large and pleomorphic lipoblasts, and is dissected by fibrous septa containing spindle cells. It requires a wide local excision, may recur locally, but never metastasizes. [from NCI]

MedGen UID:
266102
Concept ID:
C1266129
Neoplastic Process
12.

Well Differentiated Liposarcoma

A locally aggressive malignant neoplasm composed of mature adipocytes showing cell size variation and nuclear atypia. It is often associated with the presence of hyperchromatic multinucleated stromal cells, and varying numbers of lipoblasts. There are three histologic subtypes, sclerosing, inflammatory, and spindle cell liposarcoma. These tumors do not usually metastasize unless they undergo dedifferentiation. [from NCI]

MedGen UID:
237164
Concept ID:
C1370889
Neoplastic Process
13.

Sarcoma

A connective tissue neoplasm formed by proliferation of mesodermal cells. Bone and soft tissue sarcomas are the main types of sarcoma. Sarcoma is usually highly malignant. [from HPO]

MedGen UID:
224714
Concept ID:
C1261473
Neoplastic Process
14.

Mass of body structure

A benign or malignant pathologic structure in any part of the body, resulting from a neoplastic accumulation of cells, inflammatory cells, or cystic changes. [from NCI]

MedGen UID:
108287
Concept ID:
C0577559
Finding
15.

Undifferentiated Pleomorphic Sarcoma

An undifferentiated soft tissue sarcoma characterized by the presence of a pleomorphic malignant cellular infiltrate. It is also known as malignant fibrous histiocytoma. [from NCI]

MedGen UID:
87248
Concept ID:
C0334463
Neoplastic Process
16.

Spindle Cell Lipoma

A benign circumscribed tumor composed of spindled cells, adipocytes, and collagen bundles. There is no evidence of nuclear hyperchromasia or mitotic activity. [from NCI]

MedGen UID:
83153
Concept ID:
C0334474
Neoplastic Process
17.

Lipomatous tumor

A benign, intermediate, or malignant mesenchymal neoplasm composed of adipose (fatty) tissue. [from NCI]

MedGen UID:
61646
Concept ID:
C0206631
Neoplastic Process
18.

Multiple endocrine neoplasia

A group of autosomal dominant diseases characterized by the combined occurrence of tumors involving two or more ENDOCRINE GLANDS that secrete PEPTIDE HORMONES or AMINES. These neoplasias are often benign but can be malignant. They are classified by the endocrine glands involved and the degree of aggressiveness. The two major forms are MEN1 and MEN2 with gene mutations on CHROMOSOME 11 and CHROMOSOME 10, respectively. [from MeSH]

MedGen UID:
45036
Concept ID:
C0027662

155421
Concept ID:
C0743997
Finding
20.

Hibernoma

A rare benign slow growing adipose tissue tumor, characterized by the presence of polygonal brown fat cells with multivacuolated and/or granular cytoplasm. The tumor is usually painless and is most often seen in young adults. [from NCI]
