Toxoplasma gondii is known to have an affinity to lymphatic tissue. A series of 506 children with chronic tonsillitis were examined serologically for toxoplasmosis by means of CBR, IIR and ELISA. In 7.7% of the children examined low toxoplasma antibody titers were recorded. Isolation experiments performed on tonsillar tissue of the children with the highest toxoplasma antibody titers were negative. Direct microscopic evidence of tissue toxoplasma cysts failed to be established and the cytopathologic picture characteristic of nodal toxoplasmosis was not present in smears of cells aspirated from lymphatic nodes regional to palatine tonsils. The authors assumed that chronic toxoplasma tonsillitis did not occur in the series studied. In our ecological conditions, T. gondii may not be involved in the etiology of chronic tonsillitis, or it may participate to an extent which is epidemiologically negligible. (Tab. 4, Ref. 14).

Toxoplasma gondii is know to have an affinity to lymphatic tissue. The authors studied whether after infection of the child's body T. gondii does or does not determine the chronic course of tonsillitis. In 712 children with chronic tonsillitis serological examinations for toxoplasmosis were carried out by means of RVK, NIR and ELISA. Low titers of toxoplasme antibodies were found in 8.0% of the children examined. In light of the following findings the authors conclude that toxoplasme tonsillitis did not occur in their series: toxoplasma antibodies failed to be increased; their titers in seropositive children were low; toxoplasma was not isolated from tonsillar tissue; no direct microscopic evidence of the parasite could be established in smears of cell aspirate from lymph nodes regional to the palatine tonsils; the same smears failed to present the cytopathologic picture characteristic of nodal toxoplasmosis. In our ecologic conditions T. gondii is presumably not involved in the etiology of chronic tonsillitis, or it may be involved but to an epidemiologically not appreciable extent. (Tab. 10, Ref. 18).

Circulating immune complexes are thought to play an essential part in the pathogenesis of necrosing angiitis. This theory also allows a role to be attributed to certain infectious agents (viral, bacterial, parasitic) in the development of periarteritis nodosa (PAN). An infectious syndrome was found in all our 9 patients, aged 26 to 69 years, with histologically confirmed PAN: previous infection (over 15 days before hospital admission): otitis, hepatitis B, tonsillitis, ascaris (Case n.7), pulmonary tuberculosis, brucellosis, seropositivity for Chlamydia trachomatis (Case n.9), paratyphoid (Case n.5), seropositivity for Yersiniosis pseudo-tuberculosis (Case n.2), seropositivity for Chlamydia trachomatis (Cases 3 and 4), seropositivity for toxoplasmosis (Cases 4 and 6), seropositivity for rubella (Case n.8). Recent infection (less than 15 days before hospital admission): staphylococcus aureus septicaemia (Case n.1); Group A betahemolytic streptococcal urinary infection (Case n.2); Group A betahemolytic streptococcal otitis media; pseudomonas aeruginosa and Klebsiella septicaemia; enterococcal cystitis (Case n.4); progressive pulmonary tuberculosis (Case n.6), acinetobacter pneumonia (Case n.9). The HBs antigen was only found in one patient (Case n.6), who had an active hepatitis.

In immunocompetent persons, primary cytomegalovirus (CMV) infection is self-limited infection. Lymphoma-like syndromes have been sometimes described in adults but have not been described for children.Lymphoma-like syndromes (protracted fever, alteration of the general status, and clinical lymphoproliferative syndrome) were retrospectively recorded in children attending our hospital from 1999 to 2008 for primary CMV infection. Patients with immunodeficiency, coinfection (Epstein-Barr virus, toxoplasmosis, or mycobacterial), or biological criteria of mononucleosis-like syndrome were excluded.We report 4 cases of lymphoma-like syndrome. The median duration of fever was 21.5 days (range 15-27). Tonsillitis and hepatitis are most of the time missing. A probable malignant diagnosis was raised in 3 cases. Clinical outcome was protracted (15-35 days) but favorable.To our knowledge, our study is the first pediatric case series of lymphoma-like syndrome. This clinical presentation is a source of delayed diagnosis due to diagnosis pitfall.
