Complications of Acute Pancreatitis Misdiagnosed as Primary Serous Papillary Carcinoma / 대한췌담도학회지

Acute pancreatitis is an inflammatory disease of pancreas which could lead to a number of complications including pancreatic ascites and pseudocysts. When these complications are severe, the secondary changes in colon, peritoneum or mesentery can make it difficult to distinguish from peritoneal carcinomas. Herein, we report a case of acute pancreatitis that was difficult to differentiate from peritoneal carcinoma. We performed a sequential procedure without peritoneal biopsy to exclude the possibility of peritoneal cancer, and we could diagnose pancreatic ascites and pseudocyst resulting from pancreatic injuries.

Primary peritoneal serous papillary carcinoma presenting as a large mesenteric mass mistaken for ovarian cancer: a case of primary peritoneal carcinoma

Peritoneal origin serous papillary carcinoma is an uncommon primary malignancy occurring in the abdominal or pelvic peritoneum lining. It is characterized by peritoneal carcinomatosis with massive ascites, uninvolved or minimally involved ovary, and is histologically indistinguishable from ovarian serous tumors. Better recognition of this phenomenon in recent years has contributed to an increasing diagnostic frequency. We describe a rare case of peritoneal origin serous papillary carcinoma with unusual clinical presentations involving a solitary primary tumor originating from the peritoneal lining of the sigmoid colonal mesentery, without pelvic lymph node involvement or distant metastasis. Because of the location and morphological similarity, it was misdiagnosed as an ovarian malignancy. We aim to assist in the diagnosis of this disease with the following case report, thereby improving the management of patients with this condition.

A comparison of uterine papillary serous, clear cell carcinomas, and grade 3 endometrioid corpus cancers using 2009 FIGO staging system / 부인종양

OBJECTIVE: This study was designed to compare survival outcomes of patients with uterine papillary serous carcinoma (UPSC) or clear cell carcinoma (CC) to those of patients with grade 3 endometrioid carcinoma (G3EC) according to 1988 and 2009 International Federation of Gynecology and Obstetrics (FIGO) staging systems. METHODS: We retrospectively reviewed all patients with endometrial cancer treated at a single institution between 1995 and 2009. Among the 647 patients with endometrial cancer, 51 with G3EC and 46 with UPSC and CC histology were confirmed. RESULTS: 1988 FIGO stage, 2009 FIGO stage, and extrauterine metastasis were significantly different between the UPSC and CC group and G3EC group (p=0.002, p=0.041, and p=0.020, respectively). Restaging from the 1988 FIGO to the 2009 FIGO criteria increased the number of stage I cases by 10 (11.0%). Overall, 8 in the UPSC and CC and 2 in the G3EC group were down-staged to stage I. In the UPSC and CC group, the 3-year overall survival for 1988 FIGO stage I was 92.9%. When UPSC and CC patients were restaged using the 2009 staging system, the 3-year overall survival of 2009 FIGO stage I dropped to 81.6%. UPSC and CC was associated with poor OS outcome compared with G3EC, after adjustment for 2009 FIGO stage and other clinicopathologic factors. CONCLUSION: We observed that UPSC and CC patients had different prognosis according to the old and new FIGO staging system. Our results suggest that UPSC and CC compared with the G3EC may retain the 1988 FIGO to be a slightly better discriminator than 2009 FIGO.

Carcinoma papilar seroso primario del peritoneo: reporte de un caso / Peritoneum primary papillary serous carcinoma: case report

Primary serous papillary carcinoma of the peritoneum is a rare neoplasm. It is characterized by peritoneal carcinomatosis, asertes and identical histology to ovarian serous papillary carcinoma, but wrth unaffected or only superficially affected ovaries. The main differential diagnoses are secondary peritoneal carcinomatosis, peritoneal tuberculosis, malignant peritoneal mesothelioma and peritoneal lymphomatosis. The computer tomography and CA 125 are the main diagnostic tools, but the histology is essential. In this report, we present a case of a 57 years old woman with this neoplasm, metastazised to colon, uterus and ovaries. She was treated with optimal cytoreduction and chemotherapy.

El carcinoma papilar seroso primario del peritoneo es una neoplasia rara. Se caracteriza por carcinomatosis peritoneal, ascitis y una histología idéntica al carcinoma seroso papilar de ovario, pero sin comprometerlo o afectándolo sólo superficialmente. Se debe plantear como principales diagnósticos diferenciales la carcinomatosis peritoneal secundaria, la tuberculosis peritoneal, el mesotelioma peritoneal maligno y la linfomatosis peritoneal. La tomografía computada y el CA 125 representan las principales herramientas diagnósticas, sin embargo, la histología resulta imprescindible. En el presente artículo, presentamos un caso de una mujer de 57 años con esta neoplasia en que se demostró además compromiso de colon, útero y anexos. Se manejó con citoreducción óptima y quimioterapia posterior.

Clinical characteristics,treatment and prognosis of 11 cases with extraovarian peritoneal serous papillary carcinoma / 中国癌症杂志

Background and purpose:Extraovarian peritoneal serous papillary carcinoma(EPSPC) originats from peritoneum with rare incidence, sometimes may affect the surface of ovary and have multi-focal lesions, whose standard therapy have not been established. In this study, we preliminarily reviewed the clinical characteristics, treatment and prognosis of EPSPC in 11 cases. Methods:The clinical characteristics of 11 cases with EPSPC were first retrospectively analyzed. All the patients underwent cytoreduction surgery followed by chemotherapy. Finally, short-term and long-term effi cacy, time to progression (TTP) and overall survival were evaluated by RECIST, respectively. Results:Abdominal pain, distention and ascites were the most common presenting symptoms, but tumors could be palpable in only 18.2% of the patients. The positive rate of ascites, abdomen B ultrasound,MRI scan and ascending CA125 level in the plasma and ascites was 100%,45.5%,100%,72.7%,81.2%,respectively. The successful rate of cytoreduction surgery was 45.5% for the EPSPC. After chemotherapy, the cases of complete remission, partial remission, stable disease and progression disease were 1(11.1%,1/9),3(33.3%,3/9),2(22.2%,2/9) and 3(33.3%,4/9), respectively. TTP was 5-14 months for all the patients and the median TTP was 8.6 months. The 1,2,3-year overall survival was 72.7%,18.2%,0%, respectively and the median overall survival was 14.6 months. Conclusions: Ascite, abdomen MRI scan and CA125 level are the most meaningful factor to diagnose EPSPC. EPSPC is a carcinoma of poor prognostic with non-specific clinical characteristics, low successful rate of cytoreduction surgery and is chemotherapy-resistent.

A Case of Primary Peritoneal Serous Papillary Carcinoma / 대한산부인과학회지

Primary Peritoneal Serous Papillary Carcinoma has a diffuse involvement of peritoneum in the absence of an obvious primary site and is very rare. It is histologically identical to ovarian serous papillay carcinoma but involves the ovarian surface mimimally, or spare the ovaries. Clinically it is impossible to differentiate with other tumor originated from peritoneum and ovarian carcinoma because of the similarity of clinical presentation and course. Primary Peritoneal Serous Papillary Carcinoma was first described by Swerdlow in 1959 and then has been very rarely reported in literatures. A few cases were reported in Korea. We have experienced a case of Primary Peritoneal Serous Papillary Carcinoma and report this case with a brief review of concerned literatures.

A Case of Primary Peritoneal Serous Papillary Carcinoma / 대한산부인과학회잡지

Primary peritoneal serous papillary carcinoma (PPSPC) is a rare tumor that originates from a single or multicentric foci of peritoneum. Histologically the disease resembles primary serous papillary carcinoma of the ovary, but either involves the ovarian surface microscopically only or spares the ovaries entirely. Currently PPSPC is evaluated, staged and treated in the same way as epithelial ovarian cancer. We experienced one case of primary peritoneal serous papillary carcinoma which achieved a complete remission with carboplatin and paclitaxel, and report this with brief review of the literatures.

Four Cases of Primary Serous Papillary Carcinoma of Peritoneum / 대한산부인과학회잡지

Primary serous papillary carcinoma of peritoneum (PSCP) is a tumor of the peritoneum, distinct from malignant mesothelioma, but similar in many ways to primary epithelial ovarian carcinoma (EOC). It seems to be histologically identical to EOC and is differentiated from EOC based on the extent of gross ovarian involvement and microscopic invasion of the cortex. Currently, PSCP is evaluated, staged and treated in the same fashion as EOC, with the Gynecologic Oncology Group trials for the treatment of EOC now open to patients with PSCP. Therefore it is managed surgically in the same way as EOC with shared goal of optimal cytoreduction. Although the preponderance of evidence supports the benefit of maximal cytoreductive efforts for EOC, only limited data are available for debulking in PSCP. Here we report four cases of PSCP with a short literature, in who excisions of all visible implants were performed and residual lesions were measured up to less than 2 cm.

Two Cases of Primary Peritoneal Serous Papillary Carcinoma / 대한산부인과학회잡지

Primary peritoneal serous papillary carcinoma (PPSPC) is very rare and not well identified. Because of developmental, biological and histologic similarity to papillary serous carcinoma of ovary its diagnosis and treatment, prognosis and post treatment follow up schedule is similar that of epithelial ovarian cancer. We have experienced two cases of primary peritoneal serous papillary carcinoma and report this with brief review of the concerned literatures.

A case of Primary Serous Papillary Carcinoma of the Peritoneum / 대한부인종양콜포스코피학회잡지

Although the peritoneum is rare site for a primary neoplasm, certain malignant neoplasms may arise from it. A case of 63-year-old woman who had a serous papillary carcinoma of peritoneal origin is reported. Extraovarian peritoneal serous papillary carcinoma was characterized by ascites, malignant washings, and omental involvement with bulky infiltration and/or multiple tumor nodules. The symptoms caused by diffuse spreading of the neoplasm over the peritoneum are the most important manifestation for clinical diagnosis of malignant primary neoplasm of peritoneum, especially serous papillary carcinoma. This behaving tumor was at least partially responded to therapy. In this report, we describe a case of serous papillary carcinoma of peritoneum carring on proper management with brief review.
