Eosinophilic cystitis in children

Eosinophilic cystitis in children: A case report

The aim of the present case report was to investigate the clinical features, pathological examination and treatment of eosinophilic cystitis (EC) in children. Two cases of EC were reported and reviewed from January 2016 to March 2017. Case 1 (male; 6 years old) had intermittent hematuria, frequent urination, urgent urination, difficulty in urination and abdominal pain. Case 2 (male; 7 years old) had frequent urination, urgent urination, urinary pain, dysuria and suprapubic pain with no hematuria. One patient had a history of allergies and both patients underwent a cystoscope biopsy. Blood eosinophils were clearly increased and a bone marrow biopsy examination revealed that marrow eosinophils were also increased in both cases. The urine culture results were negative. Ultrasonography and computed tomography revealed uneven thickening of the bladder wall and diffusive mucosal lesions. Cystoscopy revealed that the bladder volume became smaller and the mucosa at the bladder floor and neck was red. Lesions were biopsied through the urethra and the following characteristics were observed: Congestion and edema of the bladder mucosa, infiltration of the blood vessels and eosinophils in the muscular layer, accompanied by focal muscle necrosis. Patient 1 was administered anti-inflammatory and cetirizine hydrochloride treatments, followed by 6 weeks of prednisone dose-reduction therapy. Patient 2 was administered antibiotics and cetirizine hydrochloride. Following 6-month follow-ups, abnormal voiding symptoms had disappeared in each case. Ultrasonography and computed tomography revealed no bladder wall thickening or space-occupying lesions. EC in children is rare and easily misdiagnosed as nonspecific bladder inflammation or bladder occupying lesions. Cystoscopy and biopsy are necessary to diagnose EC and conservative treatments with anti-inflammatory, anti-allergic and cortical hormone nonspecific treatments are suggested.

Pseudotumoral Eosinophilic Cystitis

Eosinophilic cystitis is a rare inflammatory disease of the bladder which origin and pathogenesis are unknown. Since the first description in 1960, hundreds of cases have been reported, 20 Pseudotumor forms. We report a case of cystitis eosinophils in tumor-form, a patient of 72 years without urological or allergic history. The patient was treated with endoscopic resection alone. The outcome was favorable with disappearance symptoms and no recurrence at 1, 3 and 6 months controls. We carry a literature review of cystitis eosinophils on the different clinical manifestations, the means diagnostic and therapeutic modalities.

Eosinophilic cystitis in the pediatric population: a case series and review of the literature

PURPOSE

Eosinophilic cystitis is a rarely seen condition in the pediatric population with indistinct symptomatology and non-standardized treatment protocols. We review our experience of treating patients with this condition.

MATERIALS AND METHODS

We retrospectively reviewed the records of four patients from a single institution who have been diagnosed and treated for eosinophilic cystitis. In addition, the literature was reviewed for cases of pediatric eosinophilic cystitis. Our patients were added and compared to this cohort.

RESULTS

Our patients included 3 females and 1 male who range in age from 5 days to 18 years (5 days, 1 month, 7 years, 18 years). Both of the infants presented with a suprapubic mass and bilateral hydroureteronephrosis. The two older patients both had dysuria while the 18 yo also complained of fatigue, flank pain, and hematuria. Only 2 of the 4 patients were found to have significant peripheral eosinophilia and only one patient had eosinophiluria. All of the patients were diagnosed via cystourethroscopy with biopsy. Treatment in each case consisted of a combination of steroids, antihistamines, and antibiotics.

CONCLUSIONS

The presentation of eosinophilic cystitis is varied and diagnosis requires a high index of suspicion. Cystourethroscopy with biopsy is essential to establish the diagnosis as there is no typical appearance of the lesions or presenting signs/symptoms. Most cases of eosinophilic cystitis are responsive to medical therapy although in some cases recurrence may be noted.

Eosinophilic cystitis: a rare cause of hematuria in children

A 7-year-old boy presented with a history of acute onset of hematuria, dysuria, and suprapubic pain. Urine routine and microscopy showed 40-45 red cells/high power field. Urine culture was sterile. Radiological investigations showed a focal mucosal lesion with bladder wall thickening. Biopsy of the lesion revealed an edematous mucosa with florid infiltration by eosinophils into the muscularis propria with focal areas of myonecrosis. He was diagnosed as a case of eosinophilic cystitis. The patient received 6 weeks of tapered prednisone therapy. He was asymptomatic on followup.

Presenting manifestations of eosinophilic cystitis in two Filipino children

Eosinophilic cystitis is a very rare clinical disease entity in the pediatric population. We report two cases of Filipino children with eosinophilic cystitis who presented with irritative voiding symptoms, gross hematuria, peripheral eosinophilia, and hydroureteronephrosis and urinary bladder wall thickening visualized on ultrasonography and CT urography. Cystoscopy and transurethral biopsy confirmed the diagnosis. Both patients were started with corticosteroid with or without an antihistamine. Resolution from the signs and symptoms were observed in both patients as documented by disappearance of peripheral eosinophilia, normal urinalysis results, and resolution of the hydroureteronephrosis and urinary bladder wall thickening on ultrasonography on follow-up.

The Spectrum of Eosinophilic Cystitis in Males: Case Series and Literature Review

Context.—Eosinophilic cystitis (EC) is an inflammatory condition of the bladder that has been linked to food allergens, infectious agents, drugs, and other genitourinary conditions. Like interstitial cystitis, EC has a strong female predominance. It is characterized by an intense eosinophilic infiltrate in the acute phase and fibrosis in the chronic phase.

Objectives.—To document and focus on specific features of EC in males and highlight the relationship between clinical and histopathologic findings.

Design.—The bladder biopsies of male patients were reviewed. Eight cases of EC were selected.

Results.—Several known associations were noted as well as unreported features and associations such as Charcot-Leyden crystals, celiac disease, lupus anticoagulant, and additional viral and bacterial agents.

Conclusions.—Eosinophilic cystitis represents a response to a variety of agents and may often be overlooked. The temporally biphasic morphologic features are the hallmark of this condition. Because clinical and imaging studies are not specific, a high index of clinical suspicion is often crucial to the correct diagnosis and proper management of EC.

Eosinophilic cystitis in a 4-year-old boy: successful long-term treatment with cyclosporin A

A 4-year-old Jewish boy presented with dysuria, urinary dribbling, increased urinary frequency, and new onset of diurnal enuresis. An infiltrating solid mass involving the entire bladder wall was found. Biopsy revealed "tumor-forming" eosinophilic cystitis, a rare bladder lesion of unclear cause. Antitoxocariasis treatment was unsuccessful. High-dose corticosteroids failed. The child's clinical condition and bladder sonographic findings continued to deteriorate. Treatment with cyclosporin A was given for 8 months, with a complete clinical, radiologic, and histopathologic cure and no side effects. Two years of follow-up showed a complete recovery.

Eosinophilic cystitis

We describe four cases of eosinophilic cystitis in whom no specific cause could be found, and review the literature. Complaints at presentation included urgency, frequency, abdominal pain, and haematuria. In three patients the symptoms and ultrasound pictures suggested a bladder tumour. One patient was treated with anticholinergics and corticosteroids without relief of symptoms; a localised eosinophilic tumour was excised in one patient who remained symptom free; and two patients were managed conservatively with spontaneous resolution of bladder pathology and symptoms. One case was identified by random bladder biopsy in 150 consecutive patients with unexplained irritable micturition complaints. Eosinophilic cystitis is rare in children. After biopsy, we consider a wait and see policy is justified as symptoms tend to disappear spontaneously. Routine bladder biopsies in children with unexplained bladder symptoms is not justifiable.

Eosinophilic granulomatous cystitis in children

We report 3 cases of eosinophilic granulomatous cystitis in children. All presented with hematuria, urinary urgency, and dysuria. Treatment with oral corticosteroids led to rapid and complete recovery in 2 of the 3 cases. In the third case recovery was prolonged without the use of steroids. Because of the presumed immunologic nature of this disease, previous authors have recommended the use of corticosteroids in its management. A review of the literature suggests that the disease is probably of immunologic nature and that corticosteroids shorten symptomatic recovery from this disease.
