Jpn. 37: 1313-1317, 1991) Key words: Cystitis glandularis, Protruding lesion, Mucin-histochemistry INTRODUCTION Cystitis glandularis is one of the prolif-erative lesions which are commonly found in the urinary bladderD , but it does not usually show a large protruding lesion in the urinary bladder. Presence of mucin-secreting glandular structures, closely re-sembling colonic crypts, is well recognized as a metaplastic change. We experienced a case of large protru-ding cystitis glandularis, and performed detailed histological and mucin-histo-chemical studies. CASE REPORT A 36-year-old man was admitted to the Department of Internal Medicine of our hosphtal in October 1988 due to acute chole-cystitis. By abdominal ultrasonography, large protruding masses were incidentally found in the urinary bladder. After recov-ery from acute cholecystitis, he was trans-ferred to the Department of Urology for the purpose of detailed examinations and treatment for the vesical lesion on Novem-ber 4, 1988. He had no urinary symptoms such as burning and difficulty on urination or hematuria. Physical, hematological, and blood chem-ical examinations were within the normal limit. Urinalysis was normal and urinary cytology was negative. He had no diffi-culty in urination and no vesicoureteral reflux (VUR). Excretory urography showed no hydro-nephrosis, but slight dilatation was seen in the lower portion of both ureters. On the urethrocystogram several filling defects of the urinary bladder were noted. CT scan demonstrated sessile protruding masses from the base of the bladder, but did not show any finding suggesting extra vesical invasion. Enhanced CT scan in the prone position revealed the tip of the prodruded mass enhanced strongly (Fig. I). Cystoscopy revealed several finger-sized nodular and sessile masses at the bladder neck and trigone, part of which showed a tower or a beak-like appearance (Fig. 2). 1314 Acta Uro!. Jpn . Vo!' 37 , No. 10, 1991 Fig . I. Enhanced CT scan demonstrates a sessile protruding mass from the base of the urinary bladder and its tip is enhanced. Fig. 2. Cystoscopy reveals some finger-sized se-ssile masses with a tower or beak-like apperance at the neck and trigone of urinary bladder. The left ureteral orifice was not recognized due to the tumorous lesion. Biopsy of this lesion disclosed a cystitis glandularis with colonic-type gland formations. Transure-thral resection of this benign lesion was performed on November 16, 1988. The border of the lesion was not so clearly identified . Eight months after the first operation cystoscopy disclosed recurrence of similar masses at the trigone, and transurethral resection was performed again. H isto-pathological diagnosis was the same as the previous one without any malignant change. Six months after the second operation, cystoscopy disclosed recurrence at the tri-gone . Transurethral resection was perform-ed for the third time. PATHOLOGY The tissue specimens were fixed in 10% formalin for 24 hours and embedded in paraffin. In addition to a routine hematox-ylin and eosin staining, to clarify the exact character of the mucin secreted, we applied several specific mucin stainings as follows: (I) periodic acid-Schiff staining (PAS), (2) high iron diamine and alcian blue (pH 2.5) stainings (HID-AB)2>, (3) periodic acid-borohydride, potassium hy-droxide and PAS stainings (PB-KOH-PAS)3). (4) paradoxical concanavalin A for stable class III stallllngs (con A ( 111»4) . PAS stains non-specifically various kinds of mucin. By HID-AB, the mucin blue in color is sialomucin, and that black in color is sulphomucin. The mucin of the small intestine and colon is positive with HID-AB2l. PB-KnH-PAS indicated the presence of O-acetylated sia-lomucin, specific to the goblet cells of the colon3). Con A (II I) is specific to the gastric type mucin4). We also applied Grimelius' staining to find endocrine cells5) Histologically, in the lamina propria of the urinary bladder, there were many Brunn's nests (Fig. 3a) with or without cysts, which were often accompanied with columnar epithelial metaplasia (Fig. 3b). Glandular structures, composed of goblet cells, were also seen to be scattered. They closely resem bled colonic crypts (Fig. 3c). Neither adenomatous nor carcinomatous Fig. 3. a. Brunn's nests, b.

Cells positive with Grimelius' staining findings were seen In these cells. These goblet cells were positive with PAS, HID-AB, and PB-KOH-PAS (Fig. 4a). In HID-AB cells with sialomucin were nearly equal to those with sulphomucin. How-ever, they were negative with con A (III). Brunn's nests were negative with PAS, HID-AB, PB-KOH-PAS and con A (III). Columnar epithelial metaplasia in Brunn's nests was slightly positive with PAS and HID-AB, but it was negative with PB-KOH-PAS and con A (III). Cells positive with Grimelius' staining were seen to be scattered in the glands (Fig. 4b) and in the Brunn's nests. DISCUSSION Cystitis glandularis is one of the prolif-erative lesions commonly found in the uri-nary bladder. I to et al. descri bed that cystitis glandularis was found in 71% of the 125 autopsy cases of macroscopically normal-appearing urinary bladders of both sexes and all ageslJ . On the other hand, including the present case, only 20 cases of cystitis glandularis with clinical symp-a 1315 toms or findings have been reported since 1970 in Japan 6 - 14>. Age distribution is from 6 to 80 years old with the average of 46 years, and it is more frequently seen in males than in females. Irritative symp-toms of the bladder are most frequent and some have gross hematuria or difficulty in urination. The incidence of these symp-toms is high in the bladder neck and tri-gone. In Japan, detailed histological studies have not been reported for the clinical cases. Koss described that cystitis glandu-laris cannot be clearly differentiated from cystitis cystica. However, in cystitis glan-dularis, cells lining the glands may be cuboidal and resemble colonic epithelium with goblet cells I5 ). According to WHO, this lesion is classified as glandular meta-plasia (glandular "cystitis"), which is cha-racterized by mucus containing columnar epithelial cells either on the surface or for-ming glands in the lamina propria 16). Many authors have reported that these mu-cus containing cells are positive with PAS. However, PAS non-specifically stains vari-0us kinds of mucin. Therefore, we applied detailed mucin-staining as described above, to clarify the property of the mucin in the present case. In this study, O-acetylated sialomucin was demonstrated in the goblet cells. Therefore, mucin of the goblet cells in cystitis glandularis was the same as that of the colon. Recently, Hamid et al. also demonstrated endocrine differentiation in inflamed urinary bladder epithelium with a metaplastic change5). By Grimelius' stain-ing, we also found endocrine cells both in the colonic-type glands and Brunn's nests. Therefore, this case also demon-strated that the bladder mucosa has a poten-tial to change toward a more differentiated glandular structure of colonic type, via Brunn's nests, as a mataplastic change. Hasegawa et al. reported using the same method as ours that the colonic type mu-cin was demonstrated not only in cystitis glandularis in autopsy cases but also in half of the cases of mucin-producing adeno-carcinomas of the bladder l7!. Wells et al. reported that adenocarcinoma of the 1316 Acta Urol. Jpn. Vol. 37, No. 10, 1991 bladder associated with cystitis glandularis produced O-acetylated sialomucin, whereas a primary adenocarcinoma of urachal ori-gin did not. Thus, they showed that PB-KOH-PAS may be used to differentiate primary adenocarcinomas from primary urachal carcinomas of the urinary blad-der1S) These findings are not only very inter-esting to explain the histogenesis of the uri-nary bladder, but also suggest that cystitis glandular is is related to the development of adenocarcinoma in the urinary bladder. There are several reports on cystitis glan-dularis which underwent a malignant change during follow-up period of 5~ 15 years 19- 2D • On the other hand, it is evi-dent, as systematically demonstrated by Ito et aLI) that cystitis glandularis is a very common autopsy finding. Clinically, Ohigashi et aL reported a case of cystitis glandularis followed for over 10 years without malignant changes!2). As a clinical practice, the patient with cystitis glandularis must be placed on the risk chart, and prolonged close follow up is obligatory.
