Ectopic endometrial glands in lymph nodes masquerading as metastatic adenocarcinoma

Endometriosis of bladder

Vesical endometriosis is the abnormal growth of endometrial tissue in the bladder. Usually small lesions occur. Three cases of endometriosis of the bladder are presented. Each case demonstrates a large intravesical lesion with striking radiographic findings that are indistinguishable from an intravesical neoplasm.

Vesical endometriosis: a review and 2 case reports

Vesical endometriosis is uncommon and can result in months or years of morbidity if undetected. We report 2 cases that demonstrate that increased awareness of this entity and expeditious use of appropriate diagnostic techniques can lead to earlier diagnosis and definitive treatment.

The significance of lymph nodal involvement in renal angiomyolipoma

Renal angiomyolipoma, a benign tumor, can involve regional lymph nodes. Although this phenomenon has been reported previously followup information has been scant. We have treated 3 patients who had renal angiomyolipoma with nodal involvement and all had further evidence of tuberous sclerosis. Each patient had hematuria with flank pain and required nephrectomy. In the ensuing 3 to 11 years none of these patients has had evidence of further disease progression. Nodal involvement may reflect the multicentricity of angiomyolipoma or may represent a form of "benign metastasis" but it does not appear to be a harbinger of disease progression.

Benign glandular elements and decidual reaction in retroperitoneal lymph nodes

Among 70 patients with gynecologic malignancies who underwent surgical staging and pelvic and periaortic lymphadenectomy, five were found to have benign glandular and/or stromal elements in the retroperitoneal lymph nodes. In three instances, these were originally diagnosed as metastatic cancer. The literature on this subject is reviewed and its significance is discussed.
