The patient indicated that he had been diagnosed and treated for syphilis in 1975, 33years previously. new ulcers at this site over the last 2 days. Asymptomatic non-specific superficial ulcers of the mandibular vestibule (Fig.1b) and soft palate covered by a yellow purulent exudate as well as a well-circumscribed, non-removable white plaque (approximately 1.5 cm) Hoechst 33342 analog of the right lateral tongue (Fig.1c) were also noted. Slightly tender submandibular lymphadenopathy was observed, with no additional systemic signs or symptoms. == Fig. 1. == Initial presentation: The dorsal tongue exhibits fissures and multiple ulcers (a) with an irregular hyperkeratotic periphery (a,inset). The mandibular alveolar mucosa shows three non-specific ulcers Hoechst 33342 analog (b). A subtle Rabbit Polyclonal to CHML homogenous white plaque of the right lateral tongue was noted (c) == Differential Diagnosis == The differential diagnosis for multiple oral ulcerations in 52-year old, HIV+ homosexual male includes infectious (i.e. bacterial, viral, fungal, protozoal) and idiopathic causes. Fungal and protozoal disease can be reasonably excluded by consideration of the specific clinical features reported. In the absence of any other systemic symptoms and the presence of shallow to slightly deepened ulcers without granularity or a tumor mass-type appearance, deep fungal infections (i.e. histoplasmosis, blastomycosis, coccidioidomycosis) or a protozoal infection (i.e. leishmaniasis) are unlikely considerations. In addition, the latter entity may be reasonably excluded based on lack of travel history to regions endemic for this condition Hoechst 33342 analog [1]. The WHO Collaborating Centre on Oral Manifestations of the Immunodeficiency Virus diagnostic criteria for oral lesions in HIV infection [2] indicate that the most likely diagnoses include: viral etiologies, reactivation of herpes simplex virus (HSV) and/or cytomegalovirus (CMV); bacterial causes, necrotizing gingivitis/stomatitis or syphilis; or an idiopathic cause, aphthous stomatitis. Ulcers due to reactivation of HSV are common in immunocompromised patients and while most often affect keratinized mucosa, any oral site may be involved [3]. They often display a scalloped, circinate yellowish/white raised border [3], somewhat distinct from the spike-like irregular, flat border identified in Hoechst 33342 analog this patient. Histopathologic examination, oral cytology, viral culture or serology are necessary to confirm this diagnosis. Infection with CMV is asymptomatic in the majority of healthy patients, while life-threatening disease may occur in the immunocompromised population. Although uncommon, oral lesions of CMV may manifest as chronic ulcerations with limited additional symptoms [4] as is present in this case. Association with HSV may also occur [4] warranting exclusion of the possibility of a mixed viral infection. Necrotizing stomatitis is a well recognized ulcerative process occurring in HIV+ patients that may represent extension of bacterial infection of the periodontium into surrounding soft tissues and bone [2]. A characteristic fetid odor and severe pain are commonly reported and the ulcers are often deep-seated [5]. These typical features are absent in the present case, warranting consideration of other possibilities. Oral ulcerations of the type described in this case could also represent a manifestation of primary or secondary syphilis. Primary syphilitic chancres are classically solitary, clean-based, painless ulcers which most often affect the genitalia and anus. In the context of coinfection with HIV, atypical presentations consisting of multiple painful chancres [6] with an irregular border [7] and oral involvement [7] are more commonplace. In this clinical setting, the oral ulcerations could represent an atypical manifestation of primary disease. The typical manifestations of secondary syphilis include lymphadenopathy, sore throat, malaise, headache, weight loss, fever, and musculoskeletal pain, along with a cutaneous maculopapular rash. Mucous patches of the tongue, lip, buccal mucosa, and palate may be seen. This Hoechst 33342 analog patient lacks these typical systemic manifestations expected for secondary syphilis. However, in the HIV-infected population, overlap of syphilitic phases has been documented [7,8] such that the lesion of the lateral tongue may represent a mucous patch of syphilis occurring concomitantly with persistent primary disease. Though recent RPR titers were negative, a detailed history of recent sexual activity, and repeated serologic testing would be helpful to exclude this possibility. Aphthous ulcerations of all three subtypes (major, minor and herpetiform) are common in HIV infected patients. They may be of new onset and are often located on the soft palate, tonsils or lateral/ventral tongue [9]. The classic appearance is that of a shallow, round/oval or slit-like ulcer with an erythematous halo. The.
