Malakoplakia of the urinary bladder following cadaveric renal transplantation in a twenty-two-year-old woman is reported. Urinary tract infection with Escherichia coli persisted postoperatively. Three years later, gross hematuria and fever occurred. Yellow-tan mucosal plaques or nodules were observed cystoscopically, and histologic examination revealed malakoplakia of the urinary bladder with characteristic foamy histiocytes containing Michaelis-Gutmann bodies. 相似文献

Malakoplakia, characterized by histiocytes with Michaelis-Gutmann bodies, is a rare entity. It is particularly so in the gastrointestinal
tract, where it has been described in association with colon cancer, with about 20 cases described worldwide. The significance
of this condition lies in its potential effect upon the preoperative staging and treatment of associated colorectal cancer.
Its presence may lead to preoperative clinical and radiological over staging and more extensive resection, as well as the
use of neoadjuvant therapy or a decision to undertake palliative care. This condition is more common in males. We present
the case of the oldest reported patient with this association. The patient was a 90-year-old female who was treated with a
sigmoid resection for an obstructing sigmoid lesion. At operation, the left ureter was embedded within an inflammatory pericolic
mass but was not grossly involved with tumor. The tumor was a Dukes’ stage B adenocarcinoma and occurred in association with
malakoplakia. 相似文献

Malakoplakia is a rare chronic inflammatory disease that was originally described in the urinary bladder but can involve many other organs and soft tissues. It is believed to be caused by an alteration in the bacterial phagocytic system. Clinically, it is described as single or multiple tumors that can appear in any part of the body. Histologically, the presence of Michaelis-Gutmann bodies is pathognomonic. Malakoplakia in children is rare. Few pediatric cases in the urinary tract, kidney, or gastrointestinal tract have been published. We present a case of urinary and gastrointestinal malakoplakia in a 12-year-old girl. 相似文献

Malakoplakia is an inflammatory granulomatous disease induced by defective phagocytic activity of macrophage. Malakoplakia is histologically characterized by the presence of Michaelis-Gutmann bodies in macrophages. Although not uncommon in the genito-urinary tract, isolated malakoplakia of the kidney is rarely found. Its main clinical presentation associates acute renal failure and acute pyelonephritis. The clue for diagnosis of renal malakoplakia is based on renal biopsy showing Michaelis-Gutmann bodies. Establishing the diagnosis of renal malakoplakia is essential as it determines the choice of antibiotics and duration of treatment. Prognosis remains poor, leading frequently to chronic renal failure. In this paper, we report four cases of renal malakoplakia and discuss clinical presentation, biological and pathological features, treatment and prognosis of this disease. 相似文献

Malakoplakia is a uncommon chronic granulomatous condition of a benign nature preferentially occurring in the genitourinary tract. Testes are affected in 12% of cases, and the first case of testicular malakoplakia was reported in 1958. Forty cases have been reported worldwide since that date. We report a new case of testicular and epididymal malakoplakia in a 68-year-old male patient diagnosed of complicated orchiepididymitis who underwent orchidectomy to rule out a malignant tumor. The histopathological study demonstrated a chronic inflammatory infiltrate with histiocytes with an eosinophilic cytoplasm containing the characteristic Michaelis-Gutmann bodies diagnostic of malakoplakia.In connection with this new case and because of its unusual presentation, the literature on testicular malakoplakia is reviewed. 相似文献

The incidence of metastatic carcinoma to the meninges (“meningeal carcinomatosis” [MC]) is increasing due to longer survival of patients and improved imaging techniques. Currently, MC is best diagnosed by cytopathological evaluation of cerebrospinal fluid (CSF). Breast primaries are the commonest cause of MC; although cytopathological features thereof have not been, as yet, fully characterized. In this study of meningeal mammary carcinomatosis, relevant clinicopathological data and archived cytopathological preparations of all “suspicious” and “positive” CSF specimens (1992–2015), from patients with a history of breast carcinoma, were retrieved and reviewed. Twenty‐three “positive” CSF specimens, derived from 15 patients formed the basis of this study. All specimens were processed as Cytospin preparations, and stained by Papanicolaou and Diff‐Quik techniques. All patients were female, with a mean age of 57 (range: 32–85) years. Mean interval between initial diagnosis of breast carcinoma and “positive” CSF was 32 (range 6–84) months. All 23 specimens (100%) were “cellular” (>10 carcinoma cells). Eighteen (78%) specimens showed only isolated nonclustered cells, and 5 (22%) specimens showed both cell clusters and isolated cells. In most “positive” cases, metastatic breast carcinoma cells showed variation in cell size, with hyperchromatic nuclei, irregular nuclear membranes, prominent nucleoli and cytoplasmic vacuolization. The background in some CSF samples showed red blood cells and fibrin admixed with rare lymphocytes and histiocytes. One specimen showed necrotic debris. Papanicolaou and Diff‐Quik‐stained Cytospin preparations were equally diagnostic, as the aforementioned findings were present in both types of preparation. 相似文献

ContextAn oligometastatic state is an early event during tumor metastatic spread and is rarely reported in patients with genitourinary tumors. In this condition, the primary tumor has low capacity for distal dissemination because its aggressiveness has not yet reached a maximum.ObjectiveTo review recent findings on the diagnosis and treatment of oligometastatic disease in patients with genitourinary tumors.Evidence acquisitionTo identify relevant studies, we reviewed articles in PubMed from January 1966 to September 2017. The search was conducted by combining the words “oligometastasis” or “oligometastatic disease” with “bladder cancer”, “genitourinary tumor”, “prostate cancer”, and “renal cancer”.Evidence synthesisIn renal cell carcinoma (RCC), tumors from patients with multiple metastases showed a different gene signature compared to oligometastatic RCC. In addition, an oligometastatic state was an independent prognostic factor for overall survival (OS). Otherwise, the characteristics of oligometastases from bladder cancer remain unclear, as do the clinical and prognostic significance of metastasectomy in this setting. However, patients with oligometastatic prostate cancer have longer recurrence-free survival and OS and seem to benefit from local metastasis-directed therapies.ConclusionsEarly detection of oligometastatic disease in patients with genitourinary tumors is fundamental in improving outcomes by identifying patients who would benefit from local approaches with potentially curative rather than palliative intent. 相似文献

ObjectiveTo document our observation of “close-loop” obstruction among patients with dual urethral obstruction from BPH and urethral stricture disease.Materials and MethodsThe hospital records of all patients that presented to our centres with evidences of urethral stricture co-existing with BPH were retrospectively reviewed from January 2007 to December 2011. Among other things, the salient features in the contrast radiograph of those with “close-loop” obstruction and their treatment were documented and analysed.ResultsForty three patients were managed for radiological evidence of urethral stricture and elevated bladder base (dual obstruction). Thirty (69.7%) of these patients had open prostatectomy with easy dilatation of the urethral stricture. Twelve (27.9%) of the patients had urethroplasty for urethral stricture diseases; of these twelve, five patients presented with persistent LUTS (“close loop” obstruction). These five (11.6%) patients were aged between 50 to 80 years; they all had suprapubic cystostomy. In addition to delineating the anatomy of the urethral stricture and elevated bladder base, other salient features on the contrast radiographies included dilated prostatic urethral, visualization of the seminal vesicles and closed bladder neck on voiding cystogram. The initial treatment was urethroplasty but two each had combination therapy (with alpha adrenergic blocker and 5-alpha reductase inhibitor) and open prostatectomy respectively as further treatment while the last patient had perineal urethrostomy as first-stage redo-urethroplasty.Conclusion“Close-loop” urethral obstruction appears to be an entity that needs further evaluation. 相似文献

Histochemical changes in bladder innervation have been described in various types of clinical and experimental neurogenic voiding dysfunction. Recent studies in the cat have shown that both decentralization and postganglionic “denervation” lead to ultrastructural changes in muscular innervation of the bladder base. The present study was conducted to find out whether these changes can be detected histochemically. Decentralization of the bladder by unilateral sacral ventral rhizotomy, bilateral sacral ventral rhizotomy, or unilateral pelvic neurectomy was performed in 25, and postganglionic “denervation” by unilateral pelvic plexus neurectomy in 9, adult male cats. Specimens of the bladder body and bladder base were collected 2–4 and 8–10 weeks after decentralization, and 2–4 weeks and 10 weeks after “denervation.” The specimens were processed by histochemical methods to demonstrate cholinergic and adrenergic nerves. No recognizable differences from the norm were observed in cholinergic muscular innervation of either the body or base specimens of the decentralized bladder. While adrenergic muscular innervation of both regions was similar to normal in short-term samples of the same specimens, there was an obvious adrenergic hyperinnervation of both in the long-term samples. By contrast, there was an obvious, early-developing, and persistent hypoinnervation by both cholinergic and adrenergic nerves in both the body and base regions after postganglionic “denervation.” It is concluded that histochemistry (1) has no value in detecting either short- or long-term changes in cholinergic muscular innervation of the decentralized bladder and (2) is useful for revealing both short- and long-term cholinergic and adrenergic hypoinnervation of the “denervated,” as well as long-term adrenergic hyperinnervation of the decentralized vesical muscularis. 相似文献
