In medicine, a targetoid object is a structure or lesion that has the appearance of a target or is target-like.
Examples:
- Target lesion
- Targetoid hemosiderotic hemangioma
- Targetoid Michaelis-Gutmann bodies
- Targetoid calcification

A lesion is any damage or abnormal change in the tissue of an organism, usually caused by injury or diseases. Lesion is derived from the Latin laesio meaning "injury". Lesions may occur in plants as well as animals.
The parietal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus.
Maud Leonora Menten was a Canadian physician and chemist. As a bio-medical and medical researcher, she made significant contributions to enzyme kinetics and histochemistry and invented a procedure that remains in use. She is primarily known for her work with Leonor Michaelis on enzyme kinetics in 1913. The paper has been translated from its original German into English.
Erythema multiforme (EM) is a skin condition that appears with red patches evolving into target lesions, typically on both hands.
Radiosurgery is surgery using radiation, that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy, it is usually used to treat cancer. Radiosurgery was originally defined by the Swedish neurosurgeon Lars Leksell as "a single high dose fraction of radiation, stereotactically directed to an intracranial region of interest".
Leonor Michaelis was a German biochemist, physical chemist, and physician, known for his work with Maud Menten on enzyme kinetics in 1913, as well as for work on enzyme inhibition, pH and quinones.
The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files. Devised by Peter Gutmann and Colin Plumb and presented in the paper Secure Deletion of Data from Magnetic and Solid-State Memory in July 1996, it involved writing a series of 35 patterns over the region to be erased.
Amy Gutmann is an American academic and diplomat who has served as the United States Ambassador to Germany since 2022. She was previously the president of the University of Pennsylvania from 2004 to 2022, the longest-serving president in the history of the University of Pennsylvania. Gutmann resigned as president on February 8, 2022, following her confirmation by the Senate as ambassador after 18 years at the University.
Response evaluation criteria in solid tumors (RECIST) is a set of published rules that define when tumors in cancer patients improve ("respond"), stay the same ("stabilize"), or worsen ("progress") during treatment. The criteria were published in February 2000 by an international collaboration including the European Organisation for Research and Treatment of Cancer (EORTC), National Cancer Institute of the United States, and the National Cancer Institute of Canada Clinical Trials Group. Today, the majority of clinical trials evaluating cancer treatments for objective response in solid tumors use RECIST. These criteria were developed and published in February 2000, and subsequently updated in 2009.
In medicine, an indication is a valid reason to use a certain test, medication, procedure, or surgery. There can be multiple indications to use a procedure or medication. An indication can commonly be confused with the term diagnosis. A diagnosis is the assessment that a particular [medical] condition is present while an indication is a reason for use. The opposite of an indication is a contraindication, a reason to withhold a certain medical treatment because the risks of treatment clearly outweigh the benefits.
Conjugate gaze palsies are neurological disorders affecting the ability to move both eyes in the same direction. These palsies can affect gaze in a horizontal, upward, or downward direction. These entities overlap with ophthalmoparesis and ophthalmoplegia.
Apical periodontitis is typically the body's defense response to the threat of microbial invasion from the root canal. Primary among the members of the host defense mechanism is the polymorphonuclear leukocyte, otherwise known as the neutrophil. The task of the neutrophil is to locate and destroy microbes that intrude into the body – anywhere in the body – and they represent the hallmark of acute inflammation.
Michaelis–Gutmann bodies, (M-G bodies) are concentrically layered basophilic inclusions found in Hansemann cells in the urinary tract. These are 2 to 10 μm in diameter, and are thought to represent remnants of phagosomes mineralized by iron and calcium deposits.
Malakoplakia is a rare inflammatory condition which makes its presence known as a papule, plaque or ulceration that usually affects the genitourinary tract. However, it may also be associated with other bodily organs. It was initially described in the early 20th century as soft yellowish plaques found on the mucosa of the urinary bladder. Microscopically it is characterized by the presence of foamy histiocytes with basophilic inclusions called Michaelis–Gutmann bodies.
Progression-free survival (PFS) is "the length of time during and after the treatment of a disease, such as cancer, that a patient lives with the disease but it does not get worse". In oncology, PFS usually refers to situations in which a tumor is present, as demonstrated by laboratory testing, radiologic testing, or clinically. Similarly, "disease-free survival" is the length of time after patients have received treatment and have no detectable disease.
Targetoid hemosiderotic hemangioma, also known as a hobnail hemangioma is a skin condition characterized by a central brown or purplish papule that is surrounded by an ecchymotic halo.
Autoimmune progesterone dermatitis may appear as urticarial papules, deep gyrate lesions, papulovesicular lesions, an eczematous eruption, or as targetoid lesions. Autoimmune progesterone dermatitis initially manifests with eye symptoms, e.g. burning, and progresses into rashes. Its relapsing-remitting pattern in women correspond to the progesterone levels during the menstrual cycle, which spike twice a month. It is an extremely rare disease.
Erythema multiforme is usually a reaction of the skin and mucous membranes that occurs suddenly. It appears as a symmetrical rash and may include the mucous membrane lesions. This means that the body is sensitive to something that causes the skin and mucous membranes to react. The more common mild form is refer to as EM minor. It consists of a skin rash that involve no more than one mucosal surface. The sudden onset will progress rapidly as symmetrical lesions with circular color changes in some or all of the lesions. Rash will spread towards center or trunk of the body. Evenly distributed bumps on the skin become classic iris or target lesions. They have bright red borders and small white bumps in the center. The cause of EM appears to be a highly sensitive reaction that can be triggered by a variety of causes. The causes can include bacterial, viral or chemical products, such as antibiotics – specifically penicillins or cephalosporins. This reaction is an allergic reaction and is in no way contagious.
David Paul von Hansemann was a German pathologist born in Eupen, east Belgium. He is remembered for his work in the field of oncology, in particular, his concept pertaining to anaplasia of cancer cells.
