The diagnosis of left lower quadrant pain is based on well-established clinical symptoms, physical examination and physician's experience.

AIM:To overview the literature on pancreatic hydatid cyst (PHC) disease, a disease frequently misdiagnosed during preoperative radiologic investigation. METHODS:PubMed, Medline, Google Scholar, and Google databases were searched to identify articles related to PHC using the following keywords: hydatid cyst, hydatid disease, unusual location of hydatid cyst, hydatid cyst and pancreas, pancreatic hydatid cyst, and pancreatic echinococcosis. The search included letters to the editor, case reports, review articles, original articles, meeting presentations and abstracts that had been published between January 2010 and April 2014 without any restrictions on language, journal, or country. All articles identified and retrieved which contained adequate information on the study population (including patient age and sex) and disease and treatment related data (such as cyst size, cyst location, and clinical management) were included in the study; articles with insufficient demographic and clinical data were excluded. In addition, we evaluated a case of a 48-year-old female patient with PHC who was treated in our clinic. RESULTS:A total of 58 patients, including our one new case, (age range: 4 to 70 years, mean ± SD: 31.4 ± 15.9 years) were included in the analysis. Twentynine of the patients were female, and 29 were male. The information about cyst location was available from studies involving 54 patients and indicated the following distribution of locations: pancreatic head (n = 21), pancreatic tail (n = 18), pancreatic body and tail (n = 8), pancreatic body (n = 5), pancreatic head and body (n = 1), and pancreatic neck (n = 1). Extra-pancreatic locations of hydatid cysts were reported in the studies involving 44 of the patients. Among these, no other focus than pancreas was detected in 32 of the patients (isolated cases) while 12 of the patients had hydatid cysts in extra-pancreatic sites (liver: n = 6, liver + spleen + peritoneum: n = 2, kidney: n = 1, liver + kidney: n = 1, kidney + peritoneum: n = 1 and liver + lung: n = 1). Serological information was available in the studies involving 40 patients, and 21 of those patients were serologically positive and 15 were serologically negative; the remaining 4 patients underwent no serological testing. Information about pancreatic cyst size was available in the studies involving 42 patients; the smallest cyst diameter reported was 26 mm and the largest cyst diameter reported was 180 mm (mean ± SD: 71.3 ± 36.1 mm). Complications were available in the studies of 16 patients and showed the following distribution: cystobiliary fistula (n = 4), cystopancreatic fistula (n = 4), pancreatitis (n = 6), and portal hypertension (n = 2). Postoperative follow-up data were available in the studies involving 48 patients and postoperative recurrence data in the studies of 51 patients; no cases of recurrence occurred in any ORIGINAL ARTICLE Submit a Manuscript: http://www.wjgnet.com/esps/ Help Desk: http://www.wjgnet.com/esps/helpdesk.aspx DOI: 10.4240/wjgs.v6.i10.190 World J Gastro...

MTX in the present cases of IGM was effective, prevented complications and limited corticosteroid side effects.

Inflammatory fibroid polyps are rare, localized, non-neoplastic lesions originating in the submucosa of the gastrointestinal tract. Intussusception due to inflammatory fibroid polyps is uncommon; moreover, ileo-ileal intussusception has only rarely been reported. Here, we report an 11 × 7 cm giant inflammatory fibroid polyp of the small bowel that presented as intussusception in a 73-year-old woman. Ultrasonography demonstrated a solid, homogeneous, echogenic mass surrounded by the typical mural layers of an invaginated ileum. The immunohistopathological diagnosis after segmental ileal resection was an ileal inflammatory fibroid polyp. Although encountered rarely in adults, physicians should be aware of invagination and consider it in each case of acute abdomen because of the wide spectrum of clinical settings.

Tuberculosis is a systemic disease with localized manifestations; therefore, anti-TB therapy must be initiated in any patient whose pathologic specimen reveals tuberculosis.

IntroductionRenal oncocytomas are benign neoplasms derived from cells of the distal renal tubule, and comprise 5% to 7% of primary renal neoplasms. Oncocytomas are mostly asymptomatic, and the majority of tumors are discovered incidentally. In this case report, we present a case of a patient with a giant oncocytoma arising from her left kidney.Case presentationWe describe a 25-year-old Turkish woman who was admitted to our hospital with abdominal pain and a 3-year palpable abdominal mass, which was found present since her second pregnancy. Examination revealed a 15 × 20-cm mass in her abdominal cavity. Computed tomography revealed a mass with regular outlines, measuring 18 × 11 × 12 cm, associated with the left kidney, and causing marked hydroureteronephrosis. We excised the mass and performed a left nephrectomy on our patient. The immunohistopathology of the mass was consistent with renal oncocytoma. No local or distant metastasis was seen at 6 months postoperatively.ConclusionTo the best of our knowledge, this is the second largest renal oncocytoma described in the English language literature. This is also the first reported giant oncocytoma that presented during pregnancy.

Benign fibrous histiocytoma is a tumor of unknown etiology that is believed to be of mixed fibroblastic and histiocytic origin. Deep benign fibrous histiocytomas are most commonly found in the lower limbs or the head and neck region; it is relatively rare that they are seen in the intercostal space. Only six case reports of this entity are described in the literature. We report a 20-year-old woman who suffered from a painless swelling in the left chest wall, with a computed tomographic correlation. The lesion was totally excised, and histopathology revealed a benign fibrous histiocytoma. This is the first case of a benign fibrous histiocytoma that arose from the intercostal space reported in the English-language literature. The six cases reported in the medical literature are also discussed.

Aim:To provide an overview of the medical literature on cutaneous fistulization in patients with hydatid disease (HD).Methods:According to PRISMA guidelines a literature search was made in PubMed, Medline, Google Scholar, and Google databases were searched using keywords to identify articles related to cutaneous fistulization of the HD. Keywords used were hydatid disease, hydatid cyst, cutaneous fistulization, cysto-cutaneous fistulization, external rupture, and external fistulization. The literature search included case reports, review articles, original articles, and meeting presentations published until July 2016 without restrictions on language, journal, or country. Articles and abstracts containing adequate information, such as age, sex, cyst size, cyst location, clinical presentation, fistula opening location, and management, were included in the study, whereas articles with insufficient clinical and demographic data were excluded. We also present a new case of cysto-cutaneous fistulization of a liver hydatid cyst.Results:The literature review included 38 articles (32 full text, 2 abstracts, and 4 unavailable) on cutaneous fistulization in patients with HD. Among the 38 articles included in the study, 22 were written in English, 13 in French, 1 in German, 1 in Italian, and 1 in Spanish. Forty patients (21 males and 19 females; mean age ± standard deviation, 54.0 ± 21.5 years; range, 7–93 years) were involved in the study. Twenty-four patients had cysto-cutaneous fistulization (Echinococcus granulosus); 10 had cutaneous fistulization (E multilocularis), 3 had cysto-cutaneo-bronchio-biliary fistulization, 2 had cysto-cutaneo-bronchial fistulization; and 1 had cutaneo-bronchial fistulization (E multilocularis). Twenty-nine patients were diagnosed with E granulosis and 11 had E multilocularis detected by clinical, radiological, and/or histopathological examinations.Conclusion:Cutaneous fistulization is a rare complication of HD. Complicated HD should be considered in the differential diagnosis of cases presenting with cutaneous fistulization, particularly in regions where HD is endemic.
