Ectomy
Ectomy A surgical suffix referring to the removal of something. For example, a lumpectomy is the surgical excision of a lump which may be benign or not, tonsillectomy is the removal of the tonsils, a partial colectomy is removal of part of the colon, an appendectomy is removal of the appendix, etc.
RELATED TERMS--------------------------------------
Lumpectomy
Surgical removal of a small cancerous or non-cancerous tumor; generally used to refer to removal of a breast lump.
Excision
1. Surgical removal, as in the excision of a tumor. 2. The removal as if by surgery, as in base excision repair.
Benign
Non-malignant; not life-threatening.
Tonsillectomy
A procedure to remove the tonsils.
Tonsils
Organs at the back of the throat that help the body fight off viral and bacterial infections; part of the immune system. No longer routinely removed when they become infected.
Colectomy
An operation to remove all or part of the colon.
Colon
Another name for the large intestine. The section of the large intestine extending from the cecum to the rectum. An adult colon is approximately five to six feet in length and is responsible for absorbing water and forming, storing and expelling waste.
Appendectomy
Surgical removal of the appendix.
Appendix
A finger-like appendage near the junction of the large intestine and the small intestine.
SIMILAR TERMS--------------------------------------
Ectoderm
One of the three primary germ cell layers (the other two being the mesoderm and endoderm) that make up the very early embryo. The ectoderm is the outermost of the three layers. It differentiates to give rise to many important tissues and structures including the outer layer of the skin and its appendages (the sweat glands, hair, and nails), the teeth, the lens of the eye, parts of the inner ear, the nerves, brain, and spinal cord. This much is classic human embryology. Stem cell research, however, has shown that some cells within ectodermal structures retain their ability to differentiate into other tissues. For example, some cells in brain (ectoderm) can become bone marrow (mesoderm).
Ectodermal
Pertaining to the ectoderm or to tissues derived from the ectoderm, one of the three primary germ cell layers that make up the very early embryo. The ectoderm is the outermost of the three layers.
Ectodermal dysplasia
A genetic disorder in which there is abnormal development of the skin and associated structures (the hair, nails, teeth, and sweat glands). The most dangerous problem occurs in cases with decreased sweating due to absence of the sweat glands. Affected persons have trouble controlling fevers and being in a warm environment. The hair may also be absent or sparse. The skin tends to be thin and light in color. Problems with the lining inside the nose predispose to chronic nasal infections. The teeth may be notably absent or develop abnormally. There are a number of different types of ectodermal dysplasia. X-linked anhidrotic (non-sweating) ectodermal dysplasia is most common. As an X-linked trait, it mainly affects males. There is also an autosomal dominant form affecting males and females alike. The term "ectodermal dysplasia" refers to the abnormal development (dysplasia) of structures derived from the ectoderm, one of the germ cell layers in the embryo.
Ectoparasite
A parasite that lives on or in the skin but not within the body. Fleas and lice are ectoparasites. Infestation with an ectoparasite is called an ectoparasitosis.
Ectoparasitosis
Infestation with an ectoparasite, a parasite that lives on or in the skin. The four major ectoparasitoses are pediculosis, scabies, cutaneous larva migrans and tungiasis (sand-flea disease).
Ectopia cordis
A type of birth defect in the heart is abnormally located. In ectopia cordis, the heart usually protrudes outside the chest.
Ectopic
Out of place. An ectopic heart beat originates in an abnormal location of the heart.
Ectopic pregnancy
Pregnancy that develops outside the uterus, usually in one of the fallopian tubes.

Ectrodactyly
The congenital absence of all or part of one or more fingers or toes. The term ectrodactyly has been applied to a variety of malformations of the fingers or toes. It is probably best reserved for: transverse terminal aphalangia (absence of the last bone in the finger or toe), adactylia (total absence of a finger or toes), or acheiria (total absence of one or both hands).
Ectromelia virus
A member of the poxvirus family which is a highly virulent natural pathogen of mice that causes mousepox, a severe disease with high mortality rate in mice but does not infect humans. The complete genome sequence of ectromelia virus is known.
