Primary inoculation tuberculosis
Primary inoculation tuberculosis (pry-muh-ree in-uh-kyuh-ley-shuhn too-bur-kyuh-loh-sis) is a form of tuberculosis that results from the direct inoculation of Mycobacterium tuberculosis into the skin or mucous membranes.
Etymology
The term "primary inoculation tuberculosis" is derived from the Latin words "primus" meaning first, "inoculare" meaning to graft, and "tuberculum" meaning small lump.
Definition
Primary inoculation tuberculosis is a rare form of tuberculosis that occurs when the Mycobacterium tuberculosis bacterium enters the body through a break in the skin or mucous membrane. This is different from the more common forms of tuberculosis, which are typically spread through the air when a person with active tuberculosis coughs or sneezes.
Symptoms
The symptoms of primary inoculation tuberculosis can vary, but often include a persistent skin lesion at the site of inoculation, regional lymphadenopathy, and sometimes systemic symptoms such as fever and weight loss.
Diagnosis
Diagnosis of primary inoculation tuberculosis can be challenging, as it requires a high degree of clinical suspicion. It is often confirmed through a combination of skin biopsy, tuberculin skin test, and sometimes polymerase chain reaction (PCR) testing for Mycobacterium tuberculosis.
Treatment
Treatment for primary inoculation tuberculosis typically involves a course of antituberculous therapy, which may include medications such as isoniazid, rifampin, pyrazinamide, and ethambutol.
