A 35-year-old woman developed typical relapsing polychondritis within a year following the onset of dermatitis herpetiformis. This occurred during a reduction in the dapsone dose regimen. To our knowledge, the coexistence of these two conditions in a single patient has not yet been reported in the literature. Both the parallel course and the good response to dapsone suggest a pathogenic link between these two diseases.
A 75-year-old male presented with typical cutaneous lesions and pulmonary involvement due to lymphomatoid granulomatosis. A legionellosis was associated with this condition. Though the radiological findings in lymphomatoid granulomatosis are suggestive, they are not specific, and set a difficult problem in distinguishing the two conditions. Monoclonal antibody studies indicated the predominance of CD8 T lymphocytes in the infiltrate of the skin, as well as in the bronchoalveolar fluid.
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.
