Abstract 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.

Eosinophilic cystitis is an inflammatory disease of the bladder wall. It is rare, so there are no standard treatment guidelines. We conducted a retrospective study of 10 patients with eosinophilic cystitis diagnosed and treated in our Department between 2006 and 2017. The average age of patients was 46 years; there was a male predominance. Three patients were atopic. The most common symptoms were irritative urinary symptoms in 9 cases, macroscopic haematuria in 8 cases and pelvic pain in 6 cases. Four patients had high levels of eosinophils in their blood. Cystoscopy showed petechiae in 5 cases, pseudotumor in 4 cases. It was normal in one case. Patients with pseudotumor underwent endoscopic resection. Four patients were treated with nonsteroidal anti-inflammatory drugs, with improvement in symptoms. Six patients were monitored. After a mean followup interval of 50 months, no recidivism was reported. Eosinophilic cystitis is rare with non-specific clinical manifestations. Patients with little symptomatic eosinophilic cystitis undergo non-invasive medical treatments. [ABSTRACT FROM AUTHOR]

Tuberculosis is a major public health problem in developing countries. Hand and wrist is a rare localization for extra-pulmonary tuberculosis, a pseudotumoral form of soft tissue tuberculosis of the wrist is exceptional. We report the case of a 45-year-old male presenting with a painful swelling of the dorsal aspect of the right wrist evolving for six months. Clinical study was evoking a ganglion cyst of the wrist. Intraoperatively a pseudotumoral mass with rice bodies was found, suggesting tuberculous tenosynovitis. The histopathological study revealed caseating giant cell granulomas with epithelioid cells. Cultures on Löwenstein–Jensen medium detected Mycobacterium tuberculosis. Synovectomy with removal of all the rice bodies followed by anti-tuberculous chemotherapy provided uneventful recovery.

BACKGROUND: "Cannon ball" opacities on chest X-rays area common manifestation of hematogenous dissemination of a malignant tumor in the lungs. They indicate an advanced stage of disease with a very grim prognosis in terms of cure and survival. In aerospace medicine, this aspect means the patient is unfit for flight duties. Nonmetastatic etiologies of pulmonary nodules are rare. We report a case of cannon ball opacities discovered fortuitously during an admission visit. CASE REPORT: A 23-yr-old flight attendant candidate came to the Aeromedical Expertise Center of the Military Hospital in Rabat for medical evaluation. He had no previous medical comorbidities and was asymptomatic.The physical examination was unremarkable. Chest X-ray revealed multiple poorly defined pulmonary nodular opacities, without mediastinal widening. After excluding other possibilities, such as infection or malignancy, the diagnosis of a pseudotumoral form of thoracic sarcoidosis was established by clinical and radiological findings, supported by histopathologic analysis. DISCUSSION: The pseudotumoral form of sarcoidosis is rare. It is usually seen in young people who are asymptomatic. Chest X-ray shows bilateral nodular opacities of different sizes. CT scan shows snowballs, which may or may not manifest with air bronchogram or mediastinal lymph nodes. Laboratory investigations are nonspecific. Pulmonary functions are normal or may show a restrictive pattern. Evolution is spontaneously favorable and does not require any treatment in asymptomatic patients. Aeromedical fitness in sarcoidosis disease depends on several conditions. This observation affirms the benefit of routine chest X-ray during medical evaulations to detect possible entities that may endanger flight safety. [ABSTRACT FROM AUTHOR]

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.

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.

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.
