[Inflammatory pseudotumor of the retroperitoneum].

Inflammatory pseudotumor is a rare, benign lesion of various organs and tissues, characterized by proliferating fibrovascular tissue admixed with inflammatory cells of etiology and pathogenesis that are largely unknown. We report a case of a 55-years-old woman with acute pancreatitis with a retroperitoneal mass in Morrison's space detected by tomography. Aspects concerning incidence, etiology, clinical, and histopathologic characteristics are discussed.

[Prevalence of different groups that comprise endoscopy-negative reflux disease].

BACKGROUND DATA: Endoscopic-negative reflux disease (ENRD) is a heterogeneous population. There are few data regarding the prevalenece of each group and subgroups that constitutes ENRD population. OBJECTIVE: To describe the prevalence of the differents groups and subgroups in ENRD. PATIENTS AND METHODS: We studied consecutive patients with frequent heartburn and acid regurgitation with endoscopically normal esophageal mucosa in whom ambulatory 24-h esophageal pH monitoring was performed. According with the pH-testing data and the correlation between symptoms and the acid reflux events, the subjects were classified in two groups: non-erosive gastroesophageal reflux disease (NERD) and functional heartburn. The functional heartburn group was splited in 3 subgroups: asymptomatics during pH-monitoring, hipersensitive esophagus and those with physiologic reflux with negative association between symptoms and acid reflux events. These last subgroup was classified in: minute changes of intra-esophegeal pH (upper than 4, n = 19) and non-acid related stimuli. RESULTS: One hundred and eleven patients with ENRD were classified in NERD (28%, n = 31) and functional heartburn (72%, n = 80). Patients with functional heartburn were classified in asymptomatics during pH-monitoring (11%, n = 12), hipersensitive esophagus (9%, n = 10) and those with physiologic reflux with negative association between symptoms and acid reflux events (52%, n = 58). In these last subgroup 19 (17%) patients were classified as minute changes of intra-esophegeal pH (upper than 4) and 39 (35%) as non-acid related stimuli. CONCLUSIONS: Even most of the patients with ENRD have normal ambulatory pH-test, their symptoms are related with drops of esophageal pH in 26% of the cases. Eleven percent do not have symptoms during ambulatory pH-monitoring.

[Peritoneal coccidioidomycosis].

BACKGROUND: Peritonitis is a very rare condition that has been found on inmunocompromised patients and patients on peritoneal dialysis. OBJECTIVE: To present one case of a patient with chronic abdominal pain that was found to have coccidioidomycosis. CASE PRESENTATION: 50 year old female with 6 months of intermittent abdominal pain referred to right upper quadrant, nausea and vomiting, without fever or jaundice. On physical exam she had pain localized to right upper quadrant. An US was performed and reported a schleroatrophic and litiasic gallbladder. Exploratory laparoscopy was performed, the findings were diffuse lesions in the peritoneal cavity parietal and visceral, some of them were biopsied. A peritoneal coccidioidomycosis was reported and fluconazol treatment was started. Postoperatory evolution was unremarkable at 3 years. CONCLUSION: Coccidioideal peritonitis is a rare disease, most of the patients are asymptomatic and frequently diagnosed while working up other disease.
