In front of a colonic tumor, the diagnosis of a pseudotumoral form of Crohn's disease must be considered. However, it is a rare form, especially when inaugural and a neoplasia must be eliminated before retaining the diagnosis.

Introduction La cystite a eosinophiles est une pathologie inflammatoire de la paroi vesicale. Elle est rare, il n’existe pas des recommandations etablies concernant sa prise en charge. L’objectif de ce travail etait d’etudier les particularites epidemiologiques, etiopathogeniques, cliniques, endoscopiques et therapeutiques des cystites a eosinophiles. Patients et methodes Il s’agit d’une etude retrospective ayant concernee dix observations de cystite a eosinophiles diagnostiquees et prises en charge dans notre service entre janvier 2006 et decembre 2017. Nous avons recueilli et etudie pour chaque cas les donnees epidemiologiques, etiopathogeniques, la presentation clinique, l’aspect endoscopique et les modalites therapeutiques. Resultats L’âge moyen des patients etait de 48 ans. Le sex-ratio etait 3/1. Un terrain atopique etait note dans 3 cas (30 %). Le mode de presentation le plus frequent etait des signes urinaires irritatifs dans 9 cas (90 %), une hematurie macroscopique dans 8 cas (80 %) et des algies pelviennes dans 6 cas (60 %). Les urines etaient steriles dans 100 % des cas. Une hyper-eosinophilie sanguine etait presente dans 4 cas (40 %). La cystoscopie avait montre des petechies dans 5 cas (50 %), un aspect pseudo-tumoral dans 4 cas (40 %) et etait normal dans un cas (10 %). Apres resection endoscopique a visee biopsique, l’histologie avait montre infiltration des couches de la paroi vesicale par des elements inflammatoires au sein desquels predominent les cellules eosinophiles. Pour les formes pseudo-tumorales une resection endoscopique a ete pratiquee. Quatre patients ont ete traites par les anti-inflammatoires non steroidien, avec amelioration des symptomes. Six malades ont ete surveilles. Apres un recul moyen de 50 mois, aucune recidive n’a ete rapportee. Conclusion La cystite a eosinophiles est une pathologie rare. Le terrain atopique peut expliquer sa survenue. La presentation clinique est non specifique. Le diagnostic differentiel se fait avec le carcinome in situ (CIS), et les tumeurs vesicales dans les formes pseudo-tumorales. La prise en charge repose sur des moyens medicaux non invasifs dans les formes peu symptomatiques.

Musculoskeletal involvement is not uncommon in extra-pulmonary tuberculosis, but the localization in the soft tissue of the hand is a very rare. Diagnosis is much more difficult because of the atypical location and non-specific symptoms. We report 6 cases of pseudotumoral form of soft tissue tuberculosis of the hand treated in our department during the past 12 years. The mean age of the patients was 51 years with extremes of 44 and 63 years. A marked female predominance was observed (sex ratio = 0.2). All patients presented with swelling of the finger, two of which were painful swelling. All long fingers were involved; the thumb was involved in two cases. The histological study after excisional biopsy revealed caseating giant cell granulomas with epitheloid cells confirming the diagnosis. Antibacillary chemotherapy promoted healing and good outcome in our patients.

Central nervous system (CSN) involvement in schistosomiasis is an ectopic manifestation with a large variety of clinical forms, including pseudotumoral, which occurs in isolated cases and is rare. Three patients with epidemiological indications of this pathology were examined; the clinical picture included lower-back pain irradiating to lower limbs, associated with progressive flaccid paraparesis and sphincterial disturbances in cases in which the spinal chord was involved; while in cases with encephalitic impairment, headache, dizziness and cerebellar syndrome, characterized by dysarthria and right-side dysgraphia, were present. Magnetic resonance imaging (MRI) showed a growing process in all cases; cerebrospinal fluid (CSF) characteristics and biological markers were compatible with neuroschistosomiasis (NS). Biopsy of the lesions confirmed this diagnosis in one case. After specific treatment with schistosomicides and corticosteroids, clinical, radiological and laboratorial improvement was observed.

The diversity of clinical presentations of primary progressive tuberculosis (TB) and the difficulty in establishing the diagnosis of paucibacillary forms is the subject of painstaking research, as well as a cause of delay in therapy. We report the case of a 10-year-old black child who presented with chest pain and progressive widening of the upper mediastinum. Computerized tomography of the chest revealed multiple calcifications that were not identified with X-rays. Biopsy through mediastinoscopy was compatible with a diagnosis of tuberculosis. Despite exhaustive investigation that included direct examination, culture for mycobacteria and PCR (Polymerase Chain Reaction) of tissue samples, the etiologic agent was not revealed. Tuberculin conversion was observed during the follow-up and resolution period of the lesion, after administration of isoniazid, rifampicin and pyrazinamide. The nodal pseudotumoral form of tuberculosis is rare in immunocompetent children and it may simulate neoplastic disease; therefore, it should be included in the list of differential diagnoses of masses located in the anterosuperior mediastinum.
