Abstract:Primary-inoculation tuberculosis of the skin resulting from direct inoculation is a rare disease first described by Laennec. Mycobacterium cannot penetrate intact skin and requires a breach in the skin to enter. The disease usually remains localized in those patients with acquired immunity from previous infection with Mycobacterium tuberculosis. The patient will develop a papule or nodule that will eventually ulcerate 2 or 3 weeks after the exposure. Lesion may resolve spontaneously or progress into a lupus vulgaris like picture. Rarely, it may lead to disseminated tuberculosis.We report a case of primary inoculation tuberculosis of keloid presenting as cold abscess.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
