background: pneumocystis carinii is one of opportunistic organisms especially in immuno-compromised patients. for years, diagnosis of pneumocystis pneumonia (pcp) has relied on microscopic visualization of organism in specimens obtained from the lung either by bronchoalveolar lavage (bal) or by induction of sputum, but failed to provide efficient diagnosis. the aim of this study was to compare ...

myiasis is the condition of infestation of the body by fl y larvae (maggots). the deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. it is an uncommon clinical condition, being more frequent in tropical countries and hot climate regions, and associated with poor hygiene, suppurative oral lesions, alcoholism and senility. the diagnosis of myi...

background: oral lesions are among the earliest clinical manifestations of human immunodeficiency (hiv) infection and are important in early diagnosis and for monitoring the progression to acquired immunodeficiency syndrome (aids). the purpose of this study was to determine the prevalence of oral lesions and their relationship with a number of factors in hiv/aids patients attending an hiv cente...

background: although color doppler ultrasonography (cdus) is useful in the diagnosis of various diseases of the head and neck, flow signals in oral malignant masses are less studied; hence the present study assesses the usefulness of color doppler ultrasonography in quantifying oral squamous cell carcinoma (oscc) vascularization. in addition, we determine the hemodynamic parameters by spectral ...

background: reactive lesions of the oral cavity are non-neoplastic proliferations with very similar clinical appearance to benign neoplastic proliferation. this similarity is troublesome in the differential diagnosis. the aim of this study was to determine the frequency and distribution of oral cavity reactive lesions. materials and methods: the study was a retrospective archive review. the med...

objective: oral lesions are among the important reasons for seeking dental care. being frequently encountered, giant cell lesions form an important group of oral lesions. the epidemiologic data on these lesions, however, is scarce in iran. the present study investigated epidemiological and demographic characteristics of giant cell lesions in oral biopsies done in one of the largest oral patholo...

BACKGROUND Oral squamous cell carcinoma (OSCC) has a remarkably high incidence worldwide, and a fairly serious prognosis. This is encouraging further research into advanced technologies for non-invasive methods of making early diagnoses, ideally in primary care settings. Method : In this article, the available objective Non-imaging methods for diagnosing OSCC have been reviewed. MEDLINE, EMBASE...

Statement of the problem: Nowadays leishmaniasis is a common infectious disease around the world which is caused by a protozoan parasite named Leishmania. This parasite is transmitted to human by an infected female sand fly. This disease has three clinical forms; mucosal forms are rare in Iran. Purpose: The purpose of this study was to report a case of leishmaniasis with lip and oral mucosal in...

Background and Aim: Oral lichen planus (OLP) is a chronic mucocutaneous disease, which is considered a precancerous condition. OLP is a multifactorial disease with no conclusive treatment. Timely diagnosis and treatment of oral lesions are necessary steps to prevent malignant transformations and severe complications of oral cancer. This study aimed to evaluate the frequency and severity of mali...

PURPOSE To identify factors associated with concordance and discordance between clinical and histopathologic diagnoses of oral lichen planus lesions. MATERIALS AND METHODS A retrospective analysis was conducted on all study cases derived from archival oral pathology reports generated from all cases of oral lichen planus accessioned by the Faculty of Dentistry, University of Malaya. These stud...
