Submental mass secondary to toxoplasmosis is not common in clinical work. A diagnosis of toxoplasmosis is rarely considered by physicians. Here we describe a 50-year-old woman presented with a progressive, painful, submental and left neck swelling for 1 month. After having obtained an insufficient evidence from the fine-needle biopsy, the patient finally received an excisional biopsy which high...

Toxoplasmosis has been reported with increasing frequency during the last decade, and the various manifestations of the human disease, with particular reference to congenital toxoplasmosis, have recently been summarized by Hutchison (1949), and Wyllie, Fisher, and Cathie (1949). All the cases thus far have been reported from America or Europe, and the case of congenital toxoplasmosis described ...

We studied the pathology of acute toxoplasmosis in experimental mice inoculated with RH strain tachyzoites of Toxoplasma gondii. All died from severe disseminated toxoplasmosis involving the liver, spleen and pancreas. Pathological features of acute toxoplasmosis in susceptible mice could be regarded as an excellent model for acute reactivation of Toxoplasma in the immunosuppressed host.

Cerebral toxoplasmosis is a common, opportunistic, and often life-threatening disease in HIV-infected patients. Diagnosis is supported mainly by clinical evidence and computerized tomography or magnetic resonance imaging scans, but brain images may share features with other brain diseases occurring in HIV-infected patients. To determine the diagnostic value of PCR for the detection of Toxoplasm...

Toxoplasmosis when occurring during pregnancy can be transmitted to the fetus and lead to congenital toxoplasmosis (CT). Therefore, pregnant women are a risk group, for which it is necessary to determine the serologic profile. The objective of this study is to determine the serologic profile of toxoplasmosis in pregnant women followed at the Parasitology Laboratory of the Pasteur Institute in T...

The clinical value of immunoenzymatic (enzyme-linked immunosorbent assay) detection of anti-Toxoplasma immunoglobulin E (IgE) was assessed by studying 2,036 sera from 792 subjects, comprising seronegative controls and subjects with acute, active, reactivated, or congenital toxoplasmosis. Included were nonimmunized adults; pregnant women with recently acquired infection (acute toxoplasmosis); im...

PURPOSE To determine the predictive imaging (CT and/or MR) features of brain toxoplasmosis recurrences in acquired immunodeficiency syndrome. METHODS The imaging studies of patients with brain toxoplasmosis were retrospectively reviewed. Forty-three patients with significant decrease or disappearance of brain lesions under specific treatment on follow-up imaging examinations were included. MR...

Toxoplasma gondii is a parasitic protozoan which is the cause of toxoplasmosis. Although human toxoplasmosis in healthy adults is usually asymptomatic, serious disease can occur in the case of congenital infections and immunocompromised individuals. Furthermore, despite the exact recognition of its etiology, it still presents a diagnostic problem. Diagnosis of toxoplasmosis is mainly based on t...

Toxoplasmosis is caused by the parasite Toxoplasma gondii and is most often a benign disease. Two populations are at risk of severe disease, immunocompromised such as HIV-infected patients and fetuses or children with toxoplasmosis transmitted from their mothers via placenta. Congenital toxoplasmosis is rare on average, less than one case per 1,000 pregnancies, since mother-to-child transmissio...
