1/19. Splenic vascular lesions: unusual features and a review of the literature.hamartoma and peliosis are uncommon splenic lesions. Approximately 120 splenic hamartomas and 40 splenic peliosis have been reported in the English literature. In the present study, a unique case of multiple splenic hamartomas with peliosis was reported. The splenic lesions were incidental findings in a 36-year-old man with ruptured sarcomatoid renal cell carcinoma. They were diagnosed clinically as metastatic renal cell carcinoma. On pathological examination, peliosis was noted in the splenic hamartomas as well as in the splenic parenchyma. In addition, the clinicopathological features of five other splenic hamartomas (including one giant hamartoma) noted in our department were presented. A re-evaluation of the features of the splenic hamartomas documented in the English literature was also done.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/19. Laparoscopic splenectomy for a giant splenic epidermoid cyst: report of a case.The use of laparoscopic splenectomy has increased in recent years, primarily for patients with idiopathic thrombocytopenic purpura (ITP). We describe herein the first known case of a laparoscopic splenectomy to be performed in japan for a patient with a giant splenic epidermoid cyst. A 26-year-old woman presented to our hospital with the major complaint of a feeling of abdominal fullness. Prior to surgery, an ultrasound-guided splenic cyst puncture was conducted for diagnostic purposes as well as to reduce the size of the cyst. The carbohydrate antigen 19-9 (CA 19-9) level was found to be elevated in the cystic contents and in the serum. Under laparoscopic guidance, the splenic vessels were ligated using a device for extracorporeal ligation, then divided. After the resected spleen had been placed in a retrieval bag, it was delivered out of the abdominal cavity without fragmentation. Following surgery, the patient's serum CA 19-9 level returned to normal. Splenic epidermoid cysts are most often encountered in young women, and laparoscopic surgery to remove cysts of this type is both minimally invasive and excellent from a cosmetic standpoint. Thus, laparoscopic surgery should be considered as the method of choice for the majority of patients diagnosed with a splenic epidermoid cyst.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
3/19. Inflammatory pseudotumor of the spleen: a case report.We report on an inflammatory pseudotumor of the spleen. A 72-year-old woman visited our hospital complaining of nausea. physical examination and laboratory investigations were unremarkable. ultrasonography, computed tomography, magnetic resonance imaging and angiography showed a hypovascular splenic mass measuring about 5 cm in diameter with a calcification in the center of the lesion. splenectomy was performed. The removed spleen, weighing 145 g, contained a tan-white, circumscribed mass, measuring 6.2 x 5.5 x 5.3 cm. Histologically, the splenic mass was composed of an admixture of inflammatory cellular elements, predominantly plasma cells and lymphocytes with hyalinization, fibrosis, lymph follicles and multinuclear giant cells, suggestive of a inflammatory pseudotumor. The patient is currently alive and asymptomatic, 24 months after surgery. Inflammatory pseudotumors of the spleen are extremely rare and only 39 cases have been reported in the medical literature.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
4/19. Giant benign true cyst of the spleen with high serum level of CA 19-9.We report the case of a 21-year-old woman with a giant (20 cm) benign mesothelial splenic cyst and a high CA 19-9 serum level (1240 U/ml). The patient underwent resection of the cyst and splenectomy. True non-parasitic splenic cysts are very rare. Only 10 cases of benign true splenic cysts, with a high CA 19-9 serum level, have ever been published in the medical literature written in English. These are reviewed in this paper. We believe that the inner cellular lining of the cyst wall produces CA 19-9, which causes the high CA 19-9 serum level. This is supported by the facts that (1) the inner cellular lining is strongly positive for immunohistochemistry with CA 19-9, and (2) the CA 19-9 serum level returned to normal after resection of the cyst.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
5/19. A true splenic cyst producing carbohydrate antigen 19-9 and cancer antigens 50 and 125, but not interleukin 10.A giant cystic lesion of the left upper abdomen associated with a smaller ovarian cyst in a young female patient is reported. Laboratory data revealed elevated serum levels of carbohydrate antigen 19-9 (CA 19-9), carcino-embryonic antigen (CEA), cancer antigens 50 and 125, and tissue polypeptide antigen. In contrast, the serum levels of interleukin 10, a cytokine involved in modulating immune responses and produced by many cancer histotypes, were normal. Since ovarian cancer or cystic adenocarcinoma of the tail of the pancreas were not ruled out, the patient underwent laparotomy. After splenectomy and ovariectomy, the tumour marker serum levels normalized. histology and immunohistochemical analysis revealed a true splenic cyst with the inner epithelium strongly positive for CA 19-9 and CEA and high levels of cancer antigens in the fluid. The ovarian lesion was a serous cystadenoma. The inner epithelium showed no immunoreactivity for tumour markers which were not measurable in the fluid. True cysts of the spleen are rare; in a few cases, high serum levels of CA 19-9 and CEA have been reported. In such instances, cyst resection or splenectomy is indicated to rule out malignant lesions and to remove the cancer antigen producing epithelium. The reported case shows that the epithelium lining true splenic cysts may produce, besides CA 19-9 and CEA, other tumour markers, in particular cancer antigens 50 and 125. In addition, normal serum values of interleukin 10 correctly predicted the benign nature of the lesion.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
6/19. Hepatic and splenic amyloidosis: dual-phase spiral CT findings.Although the liver and spleen are frequently involved in primary systemic amyloidosis, the clinical manifestations of hepatic and splenic involvement are usually mild and a dominant symptomatic hepatic presentation is uncommon. We report a case of a 51-year-old woman with giant hepatomegaly, hypertransaminasemia, increase in alkaline phosphatase, and ascites, in whom the findings of dual-phase spiral computed tomography suggested liver and splenic amyloidosis.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
7/19. Laparoscopic splenectomy for a huge splenic cyst without preoperative drainage: report of a case.Laparoscopic splenectomy currently is a safe procedure and offers better cosmetic results, less pain, and a shorter hospital stay than the traditional open procedure. However, there have been only a few reports of laparoscopic removal of giant splenic cysts. An 18-year-old woman was admitted with abdominal fullness. CT scans and MRI images of the upper abdomen revealed a cystic mass having a diameter of 19 cm. Preoperative diagnosis was a large splenic cyst, and laparoscopic splenectomy with intraoperative cyst drainage (amount of drained fluid: 3,000 mL) was performed. Histologically, almost the entire cyst wall was lined with fibrous tissue, but a small portion was covered with stratified squamous epithelium. The final diagnosis was epidermoid cyst. The postoperative course was uneventful. Laparoscopic splenectomy should be tried first even in patients with a huge cyst, and intraoperative drainage under laparoscopic guidance facilitates laparoscopic splenectomy.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
8/19. Laparoscopic marsupialization of a giant posttraumatic splenic cyst.BACKGROUND AND OBJECTIVE: Nonparasitic cysts are rare clinical lesions of the spleen. Causes include congenital malformations and trauma. Historically, management has entailed partial or total splenectomy using an open approach. Recently, laparoscopic approaches have been developed. In this report, we describe laparoscopic marsupialization of a giant splenic cyst (diameter > 15 cm). methods: A 25-year-old African-American man presented with a 9-month history of early satiety, constipation, and left upper quadrant pain. Additionally, he reported blunt trauma to the abdomen 2 years earlier. physical examination revealed a large, fixed, nontender left upper quadrant mass. Computed tomography scan confirmed a simple cyst within the spleen, measuring 20 x 25 cm. echinococcus and entamoeba histolytica serologies were negative. Laparoscopic exploration was performed. Four liters of brown fluid were aspirated and intraoperative cytology confirmed a nonparasitic cyst. The cyst wall was excised and the cavity was packed with omentum. RESULTS: The patient's recovery was uneventful, and he was discharged to home tolerating a regular diet on postoperative day 3. At 6-month follow-up, the patient was asymptomatic and showed no evidence of recurrence. CONCLUSION: Nonparasitic splenic cysts are rare lesions. Laparoscopic marsupialization is safe and effective for giant nonparasitic splenic cysts and should be considered the treatment of choice.- - - - - - - - - - ranking = 6keywords = giant (Clic here for more details about this article) |
9/19. Laparoscopic management of a ruptured giant epidermoid splenic cyst.BACKGROUND: Epidermoid splenic cysts are uncommon lesions of the spleen. They are known to become symptomatic as a consequence of enlargement, infection, or rupture, the latter being an exceedingly rare complication traditionally treated with open splenectomy. We herein report a unique case of a giant epidermoid splenic cyst that ruptured spontaneously and was successfully treated with the laparoscopic approach. CONCLUSION: Laparoscopic surgery may be considered an initial treatment option in cases of very large epidermoid cysts even when rupture occurs.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
10/19. A case of inflammatory pseudotumor in the spleen.A case of an inflammatory pseudotumor of the spleen is presented. A 43-year-old woman was hospitalized for a detailed examination due to pancytopenia, which was diagnosed during an examination related to left upper quadrant abdominal pain. physical examination revealed a 2 to 3 cm splenomegaly. reticulocyte count was 4% and erythrocyte sedimentation rate was 55 mm/h. No other important findings were noted, except for an evident increase in myeloid series and megakaryocytes (more evident in erythroid series) on bone marrow aspiration and biopsy. Computed tomography (CT) scan revealed splenomegaly and a centrally located hypodense lesion with a 92 X 86 mm axial diameter in the spleen. With a hematologic malignancy prediagnosis, a splenectomy was performed on the patient because of pancytopenia and splenomegaly. An intrasplenic, centrally located, well-limited, capsulated lesion (9.5 x 11 x 10 cm in diameter) was discovered on macroscopic examination of the material. A cellular infiltration area was seen on microscopic examination. The spleen capsule was mildly fibrotically thickened. The lesion that separated from the spleen tissue consisted of diffusely proliferated fusiform fibroblasts, heterogenous inflammatory cells consisting mainly of plasma cells, lymphocytes, sparse neutrophils and vascular elements. No granuloma or multinuclear giant cells were detected. pancytopenia improved on follow-up. The patient followed up for two years, is now healthy and has no complaints.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
