Incidental splenic littoral cell angioma complicating a case of Rolon cancer: A case report.

Littoral cell angioma (LCA) is a recently described rare generally benign primary vascular neoplasm of the spleen originating from the lining cells of the splenic red pulp sinuses that is usually discovered incidentally. LCA may be associated with epithelial malignancies and may itself also have malignant potential. We report the case of a 71-year-old woman who presented with intraoperative bleeding from the spleen during sigmoidectomy for colonic adenocarcinoma. Histopathological examination of the removed spleen revealed multiple haemorrhagic lesions diagnosed as littoral cell angioma. This case has been reported due to its rarity and to highlight how its accidental detection, unique and unexpected presentation complicated a case of colonic carcinoma. Individuals diagnosed with this tumour must be carefully evaluated to exclude primary, secondary and synchronous malignancies.

Slippage after adjustable gastric banding according to the pars flaccida and the perigastric approach.

OBJECTIVE: To evaluate laparoscopic adjustable gastric banding and the 'pars flaccida' techniques for treating morbidly obese patients. SUBJECTS AND METHODS: Between May 1999 and July 2002, 64 patients underwent laparoscopic adjustable gastric banding. The 'perigastric' technique was performed in the first 31 patients. From September 2000 the band was positioned according to the 'pars flaccida' technique in the remaining 33 patients. The patients were divided into three groups: group 1 - 'perigastric' technique using Lap-Band size 9.75 and 10 cm (31 patients); group 2 - 'pars flaccida' technique using Lap-Band size 10 cm (12 patients), and group 3 - 'pars flaccida' technique using the Swedish band (21 patients). There were 58 females and 6 males with a mean age of 36.6 years (range 17-56). The preoperative mean body mass index was 46.2 kg/m(2). RESULTS: Band slippage occurred in 10/31 patients (32.2%) of group 1, 3/12 patients (25%) of group 2 and none in group 3 patients (p < 0.01). CONCLUSION: The 'pars flaccida' technique significantly reduces the incidence of postoperative slippage after gastric banding. This complication is further reduced in the Swedish band group. Furthermore, we do not recommend using the 10-cm Lap-Band in the 'pars flaccida' technique.

Usefulness of scintimammography as an adjunct to mammography and ultrasound in the diagnosis of breast diseases.

This study was undertaken to evaluate the diagnostic efficacy of 99mtechnetium methoxyisobutylisonitrile scintimammography (SM) and combined use of mammography and ultrasound in the detection of the breast lesions in the symptomatic breast. Histopathological findings were the gold standard. Eighty patients with symptomatic breasts underwent mammography and/or ultrasound breast followed by SM. In 25 patients there were 27 lesions that were malignant and 55 patients had 65 lesions that were benign. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of SM were found to be 92, 72, 58, 96 and 78%, respectively, as compared with the combined use of mammography and ultrasound, which showed these parameters to be 89, 94, 86, 95 and 92%, respectively. In this study, SM showed slightly better sensitivity than combined mammography and ultrasound, whereas the specificity was clearly shown as higher in the latter.

Laparoscopic splenectomy for hematological disorders.

OBJECTIVES: The aim of this prospective study was to evaluate the safety and feasibility of laparoscopic splenectomy (LS) in patients with hematological disorders of the spleen. SUBJECTS AND METHODS: Between 1999 and 2001, 15 patients (11 female and 4 male), with a mean age of 30 years, underwent LS after preoperative evaluation. If difficulties were encountered in LS, one trocar site incision was enlarged to 7-8 cm to engage the left hand for hand-assisted laparoscopic splenectomy (HALS) and the procedure was completed. Various parameters were reported, including spleen size as assessed by ultrasound scan, postoperative mortality and morbidity rates, accessory spleen removal, conversion rate, operative times and length of hospital stay. LS was successfully completed in 9 patients (60%) and HALS was performed in 4 patients (26.6%). Two patients required conversion to open splenectomy. RESULTS: The mean operative time was 209 min and the mean hospital stay was 8.1 days. The hospital stay was significantly longer among HALS patients than LS patients. The mean age of patients and splenic size were associated with a significantly higher conversion rate. No deaths were attributed to the procedure. Complications occurred in 2 of 15 patients. Accessory spleens were identified in 2 patients. CONCLUSIONS: LS is both a safe and feasible procedure, but it requires great technical care to avoid serious complications.

Basidiobolus ranarum as an etiologic agent of gastrointestinal zygomycosis.

Basidiobolus ranarum is a known cause of subcutaneous zygomycosis. Recently, its etiologic role in gastrointestinal infections has been increasingly recognized. While the clinical presentation of the subcutaneous disease is quite characteristic and the disease is easy to diagnose, gastrointestinal basidiobolomycosis poses diagnostic difficulties; its clinical presentation is nonspecific, there are no identifiable risk factors, and all age groups are susceptible. The case of gastrointestinal basidiobolomycosis described in the present report occurred in a 41-year-old Indian male who had a history of repair of a left inguinal hernia 2 years earlier and who is native to the southern part of India, where the subcutaneous form of the disease is indigenous. Diagnosis is based on the isolation of B. ranarum from cultures of urine and demonstration of broad, sparsely septate hyphal elements in histopathologic sections of the colon, with characteristic eosinophilic infiltration and the Splendore-Hoeppli phenomenon. The titers of both immunoglobulin G (IgG) and IgM antibodies to locally produced antigen of the fungus were elevated. The patient failed to respond to 8 weeks of amphotericin B therapy, and the isolate was later found to be resistant to amphotericin B, itraconazole, fluconazole, and flucytosine but susceptible to ketoconazole and miconazole. One other noteworthy feature of the fungus was that the patient's serum showed raised levels of Th2-type cytokines (interleukins 4 and 10) and tumor necrosis factor alpha. The present report underscores the need to consider gastrointestinal basidiobolomycosis in the differential diagnosis of inflammatory bowel diseases and suggests that, perhaps, more time should be invested in developing standardized serologic reagents that can be used as part of a less invasive means of diagnosis of the disease.
