1/12. Signet ring cell carcinoma of a pulled-through sigmoid colon mimicking a primary invasive bladder tumor: case report and review of the literature.Primary signet ring cell carcinoma of the urinary bladder and colon are rare disease entities that are aggressive, difficult to manage, and portend a poor prognosis. We present a case report of a 25-year-old man born with an imperforate anus who developed signet ring cell carcinoma of the pulled-through sigmoid colon that mimicked a primary invasive bladder tumor. Despite radical surgery and adjuvant radiation, the patient died of his disease 7 months after surgery.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
2/12. Whole-bladder irradiation and doxorubicin-containing chemotherapy as successful treatment for a primary mucosa-associated lymphoid tissue lymphoma of the bladder.Primary bladder lymphoma, a rare disease, is usually of the low-grade mucosa-associated lymphoid tissue (MALT) type. The best treatment approach for this disease remains unknown. We encountered a case of localized MALT lymphoma with a partial high-grade component in a 27-year-old Japanese man. Taking therapeutic efficacy and the quality of life of the patient into consideration, we treated him with a combination of doxorubicin-containing chemotherapy and 30-Gy whole-bladder irradiation. The patient had a complete remission and has been disease-free without serious adverse effects or sequelae for a year and a half since completion of the treatment. These observations suggest that a combination of systemic chemotherapy and relatively low-dose irradiation without a total cystectomy is effective for a MALT lymphoma of the bladder, even with a high-grade component.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
3/12. A case report of primary osteosarcoma of the ovary.Primary osteosarcoma is one of the rare tumors affecting ovaries. This case is being reported for its rarity, along with a review of the literature. In this study, the patient, a 43-year-old woman, presented with an abdominopelvic mass. Exploratory laparotomy was performed, which revealed an extensive left ovarian mass infiltrating the uterus, small bowel, and urinary bladder. Subtotal hysterectomy and small bowel resection followed by end-to-end anastomosis and bilateral salpingo-ophorectomy were performed. Histopathology showed primary osteosarcoma of the ovary. Eighteen days after surgery, she started presenting with progressive abdominal distention and ultimately developed subacute intestinal obstruction. She was started on carboplatin and epirubicin combination but failed to respond and died of fast progressive disease. It is concluded that primary osteosarcoma of the ovary is a rare disease with poor prognosis.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
4/12. Bladder carcinoma and hiv infection during the highly active antiretroviral therapy era: A rare, but intriguing association. Two case reports and literature review.Two very rare case reports of bladder transitional cell carcinoma associated with hiv infection in patients treated with combined antiretroviral therapy are described, and discussed on the ground of the most relevant and updated literature resources. Only 13 cases of vesical carcinoma have been reported to date in the setting of hiv infection, but only 3 anecdotal single reports (the last in the y 2001) described clinical, therapeutic, and outcome issues of this rare disease association in some detail. In our patients, micro- or macro-haematuria was the clue for in-depth diagnosis and prompt treatment, which was limited to multiple local interventions in 1 case, but finally required a radical cystectomy in the second patient. No relationship was found with the very favourable underlying hiv-related virological and immunological status, and the present 8-12-month follow-up did not show disease relapses.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
5/12. Pelvic lipomatosis with cystitis cystica, cystitis glandularis and adenocarcinoma of the bladder: first reported case.Pelvic lipomatosis is a rare disease which may cause obstructive uropathy. It has been reported with cystitis cystica and cystitis glandularis. cystitis cystica and cystitis glandularis have been reported previously as progressing to adenocarcinoma of the bladder. The first reported case of pelvic lipomatosis, cystitis cystica, cystitis glandularis and adenocarcinoma of the bladder is presented and the literature reviewed.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
6/12. leiomyomatosis peritonealis disseminata.A 49 year old woman presented with leiomyomatosis peritonealis disseminata (LPD) which is a benign and very rare disease entity. This patient is particularly interesting because she presented with many atypical features. She is the second Oriental case reported, and the follow-up period was long. The disease was symptomatic and progressive despite bilateral salpingo-oophorectomy, hysterectomy and repeated excision of all the recurrent nodules. She had documented recurrences of LPD in three episodes at 4 years apart. There was no obvious systemic hormonal abnormality including pregnancy or oestrinizing granulosa tumour, and she had never taken any contraceptive drugs. The importance of differentiation of this condition from generalized metastatic intra-abdominal malignancy is discussed as LPD has a very good prognosis.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
7/12. Primary non-Hodgkins lymphoma of the bladder. Case report and review of the literature.Primary lymphoma of the bladder is a rare disease. It is usually localised for long periods. With modern radiotherapy treatment prognosis is excellent. A case report is described and the clinical, pathological and therapeutic aspects of the disease are reviewed.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
8/12. Primary osteogenic sarcoma of the bladder. Case report and review of the literature.Primary osteogenic sarcoma of the bladder is an extremely rare disease. Fewer than 30 cases of tumors of the bladder containing bone or cartilage have been reported. Only 14 cases of well-documented primary osteogenic sarcoma of the bladder appear in the world's literature. The authors describe the first detailed description of such a patient treated with radiotherapy and chemotherapy as well as provide a review of this rare and interesting entity.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
9/12. Multiple leiomyomata of the urinary bladder in a hysterectomized woman.A 47 year-old previously hysterectomized para 0 gravida 0 presented with hematuria, abdominal pain and a palpable pelvic mass. cystoscopy was normal. An ovarian tumor was suspected. At operation three leiomyomata originating from the bladder wall were found. This is a rare disease with only about 160 cases hitherto reported in the literature. The present case represents, as far as I know, the first case of multiple bladder leiomyoma reported in a woman. Bladder leiomyomata are a very rare differential diagnosis to ovarian tumors.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
10/12. radiotherapy with iodine-131 in recurrent malignant struma ovarii.Malignant struma ovarii is a very rare disease and, therefore, there is neither common agreement on treatment regimens nor sufficient follow-up experience. We present a case of a 49-year-old woman with malignant struma ovarii of the follicular type, who received ablative radioiodine treatment after thyroidectomy and surgical removal of the primary tumour. During follow-up examinations an increasing thyroglobulin level was found, caused by a tumour relapse with suspected urinary bladder infiltration on CT and proven uptake of radioiodine on whole-body scanning with iodine-131. After administration of 6GBq 131I, complete tumour regression was achieved with no evidence of a new relapse during a 30-month follow-up period. Correspondingly, repeated thyroglobulin measurements were all negative. This case demonstrates the benefit of combined surgical and radioiodine treatment of malignant struma ovarii for both monitoring and therapy of relapse or metastases; thus, the same therapeutic regimen as is employed in primary differentiated thyroid carcinoma may be recommended.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
