Pseudo-tumeur inflammatoire cardiaque mimant un myxome.

La pseudo-tumeur inflammatoire de localisation cardiaque est une entité rare et bénigne. Elle peut souvent mimer une tumeur maligne dans sa présentation clinique et radiologique, pouvant entrainer un retard diagnostic. Nous rapportons le cas d'un patient âgé de 20 ans, sans antécédents médicaux, admis dans le service pour l'exploration d'une fièvre prolongée. Un myxome du ventricule droit a initialement été suspecté sur l'imagerie. Une résection complète de la masse cardiaque a été effectuée. L'étude histopathologique a conclu à une pseudo-tumeur inflammatoire. Ce cas vise à présenter les caractéristiques cliniques, radiologiques, histologiques ainsi que la prise en charge d'une pseudo-tumeur inflammatoire cardiaque.

Brucellar spondylodiscitis: A case series with focus on histopathological features.

Brucellar spondylodiscitis (BS) is the most common form of musculoskeletal brucellosis. The isolation of Brucella spp from blood, other body fluids or tissue cultures is the gold standard for definitive diagnosis of BS. BS shows a large histopathological spectrum of lesions with non-specific and granulomatous forms, and its histopathological features are not widely reported. This case series study reported the histopathological features of a series of 21 BS. Ten cases revealed nonspecific forms of BS. Lymphocytes were the predominant inflammatory cells in this group. In one case neutrophils were predominant. The eleven remaining were granulomatous. The 11 exhibited histiocytic type granulomas. Ten were non-necrotizing. One case, taken from abscess wall, contained minimal deposition of caseous like necrotic material. This case and 2 others corresponding to abscess wall biopsies, showed histiocytic granulomas mixed with small aggregates of epithelioid cells without well-formed epithelioid granuloma nor giant cell. The histopathological diagnosis of BS is challenging. Nonspecific forms of BS, mimiking pyogenic spondylodiscitis, are observed in about half of the cases. Although nonspecific forms of BS are characterized by the predominance of lymphocytes and plasmocytes, BS forms with predominant neutrophil cell infiltration do exist. Histiocytic granuloma is highly suggestive of BS. Purely epithelioid forms of BS were not observed in the present series. Caseous like necrosis suggestive of tuberculosis is a possible feature of BS.

[Epidemio-clinical features of genital tuberculosis among Tunisian women: a series of 47 cases]. / Caractéristiques épidémio-cliniques de la tuberculose génitale chez la femme tunisienne: une série de 47 cas.

This study aimed to identify the epidemio-clinic, diagnostic, therapeutic and evolutionary features of genital tuberculosis (GT) among Tunisian women. We conducted a retrospective, descriptive study in the Department of Infectious Diseases at the La Rabta Hospital, Tunisia, over a period of 15 and a half years (January 2000 - June 2014). All patients hospitalized for genital TB were included in the study. The study focused on 47 cases. The average age of patients was 42.2 years. Eighteen women were from rural areas. Tuberculous contact was found in five cases. In all cases, the onset was insidious. Twenty-three patients showed one or several signs of TB infection. Tuberculin intradermal reaction (IDR) test was performed in 35 women (74.8%), it was positive in 26 cases (74%). Thirty-nine patients (83%) had undergone radiological examination using abdomino-pelvis ultrasound and/or CT scan. Diagnostic coelioscopy was performed in 37 cases (75.5%). Anatomopathological examination helped to confirm the diagnosis of GT in 42 cases (89.3%), showing epithelioid and giant-cell granuloma. We identified 21 cases of isolated GT, the remaining 26 cases had peritoneal involvement. All patients received specific antibiotic therapy combining isoniazid, rifampicin, pyrazinamide and ethamubutol with an average treatment duration of 12 months. No patient received corticosteroids or secondary surgery. Patients' outcome was favorable in 39 cases, 8 patients were lost to follow-up. Genital tuberculosis is rare, representing only 0.5% of extra-pulmonary tuberculosis, but it accounts for a high prevalence of clinical polymorphism. Diagnostic confirmation is difficult and it is based on bacteriological and/or histological examinations. Diagnosis should be suspected in patients with chronic abdominopelvic symptoms, in women with infertility associated with suggestive epidemioclinical manifestations.

Paradoxical reaction associated with cervical lymph node tuberculosis: predictive factors and therapeutic management.

OBJECTIVES: The aims of this study were to determine predictive factors of paradoxical reaction in patients with cervical lymph node tuberculosis (TB) and to discuss the therapeutic management of this condition. MATERIALS AND METHODS: A retrospective study was performed of 501 patients managed for cervical lymph node TB over a period of 12 years (from January 2000 to December 2011). Statistical data were analyzed using IBM SPSS Statistics version 20.0. RESULTS: Paradoxical reaction occurred in 67 patients (13.4%), with a median delay to onset after starting TB treatment of 7 months. Lymph node size ≥3cm and associated extra-lymph node TB were independently associated with paradoxical reaction. Treatment consisted of surgical excision (71.6%), restarting quadruple therapy (10.4%), reintroduction of ethambutol (23.8%), and addition of ciprofloxacin (20.8%); steroids were given in two cases . All patients recovered after an average treatment duration of 14.91±7.03 months. CONCLUSION: The occurrence of paradoxical reaction in cervical lymph node TB seems to be predicted by associated extra-lymph node TB and a swelling size ≥3cm. The treatment of paradoxical reaction remains unclear and more randomized trials are necessary to improve its management.
