The authors report a case of giant nodular posterior scleritis mimicking choroidal tumor. Fundus fluorescein angiography (FFA) and ultrasonography were suggestive of a mass lesion, which resolved with oral steroids. Giant nodular posterior scleritis is a possibility in any amelanotic choroidal mass lesion especially if associated with pain. Ultrasonography and FFA differentiates it from amelanotic melanoma and choroidal hemangioma.
Cutaneous draining sinus tracts of odontogenic origin often are a diagnostic challenge. A delay in correctly diagnosing these types of lesions can result in unnecessary antibiotic therapy and surgical treatment. This case report presents the clinical course of two cases with extra-oral sinus tract formation, from diagnosis and treatment to short-term follow-up and evaluation. These facial lesions were initially misdiagnosed as lesions of non-odontogenic origin. Later on an odontogenic cause was identified and endodontic intervention resulted in resolution of the problem, confirming the initial misdiagnosis.
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.
