1/16. Prostatic cystadenoma presenting as a large multilocular mass.A case is reported here of a patient with a giant multilocular prostatic cystadenoma who presented with gross hematuria and underwent extensive surgical resection. A 35-year-old man presented with asymptomatic gross hematuria. magnetic resonance imaging of the pelvis demonstrated a multilocular mass replacing the prostatic gland. At exploration the urinary bladder was found to be displaced anterolaterally and severely adherent to the large tumor. The pathological features were consistent with multilocular prostatic cystadenoma. There have been no signs of tumor recurrence during 24 months' follow-up after surgery. Although the natural history of prostatic cystadenoma remains unknown, complete surgical excision may not always be necessary. physicians should at least be aware of the possibility of this disease entity before making treatment decisions.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/16. Giant multilocular cystadenoma of the prostate: a rare differential diagnosis of benign prostatic hyperplasia.We report a case of giant multilocular cystadenoma of the prostate in a 43-year-old man. This is a rare benign entity of the prostate imitating symptoms of benign prostatic hyperplasia and originates from the prostate with extensive spread into the pelvis. Histologically, prostatic glands and cysts lined by cuboid to columnar epithelial cells with basally located nuclei are characteristic. Immunohistochemical staining is positive for prostate-specific antigen in the epithelial cells. Giant multilocular prostatic cystadenoma should be taken into account in the differential diagnosis in any case of a large cystic mass originating from the prostate.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
3/16. Giant, benign, mucinous cystadenoma of the ovary: case study and literature review.Benign, mucinous cystadenomas account for 15 per cent of all ovarian neoplasms. Of these, the giant variant occurs rarely. A morbidly obese, 52-year-old, white woman was seen for acute abdominal pain and diagnosed using computerized tomography as having a giant, benign, mucinous cystadenoma. At laparotomy, 21-kg cystic mass attached to the right ovary was removed. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. In such patients, special consideration must be given to hemodynamic and ventilatory monitoring and intraoperative fluid management. Recognition and subsequent surgical management of this and other large abdominal masses can be optimized by thoughtful, preoperative evaluation and careful planning of the operative approach.- - - - - - - - - - ranking = 2keywords = giant (Clic here for more details about this article) |
4/16. Haemorrhagic papillary cystadenoma of the seminal vesicle mimicking giant seminal vesicle cyst: MRI appearances.Papillary cystadenoma of the seminal vesicle is very rare. We describe such a case presenting in a 58 year old man with bladder outlet obstruction. Investigations included magnetic resonance imaging (MRI), the usefulness of which in pre-operative diagnosis is highlighted in this case. Seminal vesicle cysts can usually be identified by conventional radiological imaging techniques such as ultrasound and computed tomography; however, identification would be difficult if the cyst is very large, causing distortion of the adjacent anatomy. In such cases, MRI, through coronal and sagittal scanning, can be helpful in localising the lesion, as in this patient. The precise pathological nature of the cyst can only be confirmed by biopsy.- - - - - - - - - - ranking = 4keywords = giant (Clic here for more details about this article) |
5/16. Angiographic findings in some rare pancreatic tumors.Angiographic findings in one giant cell carcinoma, one cystadenocarcinoma, one poorly vascularized mucinous cystadenocarcinoma, as well as in two avascular (gastrin- and glucagon-producing) islet-cell tumors of the pancreas are described. Two hypervascularized islet-cell tumors are presented for comparison and a case of tumorous chronic pancreatitis in a child is reported because ot its rarity. The aggressiveness of the giant cell carcinoma of the pancreas was demonstrated by its expansive growth. In the case of cystadenocarcinoma angiography revealed the tumor with hepatic metastases not diagnosed at explorative laparotomy. The relative hypovascularity in the case of mucinous cystadenocarcinoma was unusual. Both avascular islet-cell tumors simulated a pancreatic pseudocyst and the final diagnosis was made only by immunoassay. Chronic pancreatitis in a child presented with marked hypervascularization.- - - - - - - - - - ranking = 2keywords = giant (Clic here for more details about this article) |
6/16. Giant multilocular prostatic cystadenoma: a distinctive lesion of the retroperitoneum in men. A report of two cases.Two examples of large, multiloculated, cystic tumors that arose within the pelvis in men of 28 and 37 years of age are described. The tumors were composed of glands and cysts lined by prostatic-type epithelium lying in a hypocellular fibrous stroma. The prostatic nature of the lesions was confirmed by immunohistochemical staining of the epithelium for prostate-specific antigen and prostatic acid phosphatase. Two apparently similar lesions were found in the literature; one tumor was attached to the prostate by a pedicle, and the other arose in the retrovesical space. These tumors, for which we propose the designation "giant multilocular prostatic cystadenoma," appear to be benign, although they may recur if incompletely excised. They may pose considerable diagnostic difficulty if the prostatic nature of the epithelium is not appreciated, an error that is likely if a relationship to the prostate is not recognized. This lesion should be included in the differential diagnosis of retroperitoneal cystic tumors in men.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
7/16. Rare tumors of the skull base and temporal bone.skull base surgery has advanced significantly in the last decade. Neuro-otologists and neurosurgeons are working together to apply their combined expertise to totally remove skull base lesions with minimal additional neurologic deficit. Standard approaches have been developed for the more common lesions of the skull base, such as the glomus jugular tumor. Rare tumors of the skull base can be removed using the standard skull base surgery techniques. However, there are specific problems with some of these tumors. This article will describe four types of unusual skull base tumors: hyalinized chemodactoma, giant cell tumor of the bone, papillary adenoma of the middle ear, and ganglioneuroma. The unique properties of these tumors and the surgical approach to their removal will be presented and illustrated by case reports.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
8/16. Removal of a giant ovarian cyst. Anaesthetic and intensive care management.Excision of a giant ovarian cyst may be associated with considerable mortality. Problems stem from the size of the cyst and the emaciated state of the patient. We describe a case in which the patient's pre-operative nutritional and psychological state required attention. Gradual pre-operative drainage of a cyst weighing 113 kg was carried out successfully. The main problems intra-operatively stemmed from copious blood loss and the duration of surgery. Postoperatively, ventilatory inadequacy occurred and was probably caused by altered mechanics of ventilation, postoperative pain and pulmonary oedema. We suggest ways in which the management of such cases might be improved.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
9/16. giant cell arteritis of the female genital tract. A report of three cases.Three cases of giant cell arteritis involving the female genital tract of postmenopausal women are reported. The patients were 80, 64, and 57 years of age and presented with fatigue and anemia, fatigue and an abdominal mass, and fever and weight loss, respectively. Two of the patients had palpable pelvic masses; one had an ovarian mass visible on ultrasound examination. All three patients were anemic, and the erythrocyte sedimentation rate was elevated in the two women in whom it was tested. Exploratory laparotomy revealed ovarian tumors in two patients; one had a mucinous cystadenoma, and one had bilateral ovarian fibromas. The third patient had a cyst of the rete ovarii. Extensive giant cell arteritis of the small to medium-sized arteries was found unexpectedly in the ovaries and fallopian tubes of two patients who had prior hysterectomies and in the ovaries, fallopian tubes, and uterus of one patient. One patient was treated postoperatively with prednisone with improvement of symptoms and a decrease in the erythrocyte sedimentation rate. Of the two patients who received no therapy, one was found to have a thoracic aortic aneurysm 5 years postoperatively, and the other was alive without symptoms 17 years after the operation. giant cell arteritis of the female genital tract is a rare finding in elderly women and may occur as an isolated finding or as part of generalized giant cell arteritis.- - - - - - - - - - ranking = 3keywords = giant (Clic here for more details about this article) |
10/16. cholesterol granulomas in lymph nodes draining a benign ovarian neoplasm.A 69-year-old woman underwent a hysterectomy and bilateral salpingo-oophorectomy for a 20-cm right ovarian tumor. Multiple peritoneal and lymph node biopsy specimens were obtained to determine the clinical stage. Despite the surgeon's concern of malignancy, pathologic examination demonstrated a benign mucinous cystadenoma. Periaortic and external iliac lymph nodes showed an unusual granulomatous reaction, with multinucleated giant cells surrounding cholesterol-like clefts. Analysis of cyst fluid from the ovarian tumor revealed high concentrations of protein and lipid; the lipid component was predominantly free cholesterol (0.61 mumole/mL) and phospholipid (0.225 mumole/mL). We speculate that fluid from the ovarian neoplasm drained into regional lymph nodes, causing this unusual granulomatous response.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
