Idiopathic Granulomatous Mastitis: Time to Avoid Unnecessary Mastectomies

Abstract:  Idiopathic granulomatous mastitis is a rare disease of the breast. Clinically and radiologically it may mimic breast carcinoma. Awareness of surgeons, pathologists, and radiologists is essential to avoid unnecessary mastectomies. Data regarding 24 patients with histologically confirmed idiopathic granulomatous mastitis treated at our center over 8 years were analyzed. The mean age of patients was 34.3 years. Breast lump was the most common presentation. The right breast was affected in 16 cases. Four patients were pregnant at the time of presentation. Lactation within 6 months of presentation was documented in four patients. Two patients used contraceptives pills. A clinical suspicion of malignancy was present in 17 cases. Mammography was performed in 16 patients and showed focal asymmetrical dense lesions in 9, well‐circumscribed opacity in 4, spiculated lesion in 1, and was normal in 2. Fine‐needle aspiration was performed in 17 patients, of which 2 were reported as malignant. Wide local excision was the mainstay of treatment. One patient underwent mastectomy upon clinical, mammographic, and repeated cytologic findings consistent with malignancy, and the final histology confirmed idiopathic granulomatous mastitis with no evidence of malignancy. Four patients developed recurrence after a mean follow‐up of 31.2 months. A greater awareness of the rare entity of idiopathic granulomatous mastitis is mandatory to avoid unnecessary mastectomies. Clinical, radiologic, and even cytologic findings are sometimes confused with malignancy. To the best of our knowledge, our patient who developed the disease at the age of 11 years is the youngest reported case. 

Fournier's gangrene: changing face of the disease.

PURPOSE: Our experience with ten cases of Fourniers gangrene prompted us to review the related literature to highlight the current status of the disease. METHODS: Data from ten patients with the diagnosis of Fourniers gangrene treated at our center from January 1997 until December 1998 were analyzed. These patients were treated by aggressive resuscitation, triple antibiotics, and urgent surgery. The English-language medical literature for the past 30 years was reviewed. RESULTS: The epidemiologic features of our patients were similar to those reported in other recent studies. Mortality rate was 20 percent. Currently, the disease affects both genders and a wide range of ages, has a more insidious onset than in the past, and is not idiopathic. Associated systemic disorders (diabetes, alcoholism, and immunosuppression) are common. Perianal infection is the commonest cause and is associated with more moribund features. CONCLUSION: The epidemiology of Fourniers gangrene is changing from its original description. Population aging worldwide—as a result of improving health care—and therefore the increasing prevalence of associated medical disorders may explain these changes. These factors may also explain the consistently high mortality rate during more recent years, masking any survival benefits from improved medical care. Better understanding of the pathophysiology has reduced the ratio of idiopathic cases to a minimum.

Feasibility of Laparoscopic Cholecystectomy in Situs Inversus

PURPOSE To address the feasibility and safety of laparoscopic cholecystectomy in situs inversus and highlight the necessary modifications in the surgical technique. PATIENTS AND METHODS We present our experience in two patients with situs inversus and symptomatic gallstones who were treated successfully by laparoscopic cholecystectomy. The surgeon stood on the right side with the video monitor above the patients left shoulder. Two 10-mm ports were placed in the epigastric and subumbilical positions. Two 5-mm ports were placed in the left mid-clavicular and left anterior axillary lines. The two procedures were carried out uneventfully after reorientation of the visual-motor skills of the surgeon and cameraman to the left upper quadrant. A summary of a further similar 13 cases so far treated in the English-language medical literature is also presented. RESULTS Skeletonizing the structures in Calots triangle consumed extra time and was more difficult than in patients with a normally sited gallbladder. However, the hospital stay and postoperative complications were similar. CONCLUSION Laparoscopic cholecystectomy in situs inversus seems to be feasible and safe provided it is performed by an expert laparoscopic surgeon who takes time in clearly demonstrating the extrahepatic mirror image anatomy of the biliary tree with its right-to-left shift.

Differing DNA methylation patterns and gene mutation frequencies in colorectal carcinomas from Middle Eastern countries

Purpose: The epidemiology of colorectal carcinoma is well known to differ among countries but the molecular characteristics are usually assumed to be similar. International differences in molecular pathology have not been studied extensively but have implications for the management of patients in different countries and of immigrant patients. Experimental Design: We evaluated the CpG island methylator phenotype pathway characterized by concordant methylation of gene promoters that often silences transcription of the genes, the microsatellite instability pathway, and K-ras and p53 gene status in 247 colorectal carcinomas from the three selected Middle Eastern countries of Egypt, Jordan, and Turkey. Results: Colorectal carcinoma from Egypt had the lowest frequencies of methylation. In multinomial logistic regression analysis, Jordanian colorectal carcinoma more frequently had methylation involving the p16 tumor suppressor gene (odds ratio, 3.5; 95% confidence interval, 1.2-10.6; P = 0.023) and MINT31 locus (odds ratio, 2.3; 95% confidence interval, 1.0-5.1; P = 0.041). The K-ras proto-oncogene was more frequently mutated in colorectal carcinoma from Turkey (odds ratio, 2.9; 95% confidence interval, 1.2-6.7; P = 0.016), but p53 overexpression was more common in both Jordanian and Turkish colorectal carcinoma than in Egyptian cases (odds ratio, 2.5; 95% confidence interval, 1.2-5.5; P = 0.019; and odds ratio, 3.6; 95% confidence interval, 1.8-7.1; P = 0.0003, respectively). The findings in Turkish colorectal carcinoma were most similar to those reported for Western cases. Conclusions: Colorectal carcinoma from Middle Eastern countries have differing gene methylation patterns and mutation frequencies that indicate dissimilar molecular pathogenesis, probably reflecting different environmental exposures. These molecular differences could affect prevention strategies, therapeutic efficacy, and transferability of clinical trial results.

Colorectal adenocarcinoma in a defined Jordanian population from 1990 to 1995

PURPOSE: This study aims to evaluate cancer of the large bowel as it occurred in a defined Jordanian population, with special reference to its epidemiologic aspects. Second, this study was undertaken to compare these results with those of other countries and those previously reported from Jordan. METHODS: Records of patients diagnosed as having colorectal adenocarcinoma during a six-year period in Irbid province, Jordan, were reviewed. The material was analyzed retrospectively with respect to various epidemiologic features, and the results were compared with those of other countries and those previously published about the Jordanian population. RESULTS: Between January 1990 and December 1995, 109 new patients with colorectal adenocarcinoma were managed, an incidence of 3.8/100,000/year. Male to female ratio was 1∶1.05 for colonic cancer and 1.36∶1 for rectal cancer. The maximum incidence was seen in the sixth and seventh decades. A total of 12.8 percent of the patients were younger than 40 years of age. The rectum was the most common site involved in 30.3 percent of the patients, followed by the sigmoid, right colon, and the rest of the colon. When compared with previous Jordanian figures, a shift toward the western figures was noted. The delay in diagnosis was noted from the 8.2 months of delay before diagnosis and the advanced stage of the disease at the time of diagnosis. A total of 49.5 percent of the cases were in Dukes B stage, 30.3 percent in Dukes C, and 19.3 percent in Dukes D. Only one patient was in Dukes A stage. A total of 13.8 percent of the cases were mucinous adenocarcinoma. A total of 26.5 percent of the patients presented with complications. CONCLUSIONS: As for colorectal adenocarcinoma, we still share the epidemiologic characteristics of developing countries, but there is a shift toward those of western communities. Flexible sigmoidoscopy is encouraged for evaluation of lower gastrointestinal symptoms, and education of the public and medical staff about colorectal diseases is needed to improve the outcome.

Torsion of abdominal appendages presenting with acute abdominal pain.

BACKGROUND Diseases of the abdominal appendages are rare causes of abdominal pain in all age groups. PATIENTS AND METHODS Nine patients with torsion and infarction of abdominal appendages were retrospectively reviewed. RESULTS Four patients had torsion and infarction of the appendices epiploicae, four patients had torsion and infarction of part of the greater omentum, and one patient had torsion and infarction of the falciform ligament. The patient with the falciform ligament disease represents the first reported case of primary torsion and infarction of the falciform ligament, and the patient with the transverse colon epiploica represents the first reported case of vibration-induced appendix epiploica torsion and infarction. The patient with the falciform ligament disease presented with a tender upper abdominal mass, and the remaining patients were operated upon with the preoperative diagnosis of acute appendicitis. CONCLUSION The presence of normal appendix with free serosanguinous fluid in the peritoneal cavity should raise the possibility of a disease, and calls for further evaluation of the intra-abdominal organs. If the diagnosis is suspected preoperatively, CT scan and ultrasound may lead to a correct diagnosis and possibly conservative management. Laparoscopy is playing an increasing diagnostic and therapeutic role in such situations.

Postcatheterization femoral artery pseudoaneurysms: Therapeutic options. A case-controlled study

OBJECTIVES Postcatheterization femoral artery pseudoaneurysm is a troublesome complication following percutaneous canulations of the femoral artery. Both diagnostic and therapeutic options in the management of these pseudoaneurysms have changed dramatically, with surgery being required only rarely. We aimed to perform a comprehensive review of our experience, techniques and results in treating postcatheterization femoral artery pseudoaneurysms. METHODS A retrospective study of all patients presenting with local complications following invasive percutaneous femoral artery canulations over a five-year period was performed. Physical examination with color Doppler ultrasound analysis identified 29 femoral artery pseudoaneurysms. Surgery, duplex-guided compression, and thrombin injection were the main therapeutic options. RESULTS Fourteen cases of femoral artery pseudoaneurysms were treated by duplex-guided compression obliteration with a 78.5% success rate. Four patients had spontaneous thrombosis of their pseudoaneurysms. Five patients underwent percutaneous thrombin injection. Six patients had conventional surgery. Three cases failed duplex-guided compression: one closed with thrombin injection, and two were repaired surgically. Follow-up US showed no recurrent pseudoaneurysms for patients who underwent successful duplex-guided compression. CONCLUSION Despite the voluminous data in the literature of treating postcatheterization femoral artery pseudoaneurysms by thrombin guided injection, as a quick and effective method of therapy, with infrequent failures and complications, our study confirms the clinical usefulness of duplex-guided compression in the management of these pseudoaneurysms. The possibility of spontaneous thrombosis of small pseudoaneurysms is emphasized.

Primary gastric lymphoma in Jordan with special emphasis on descriptive epidemiology

The aim of this study was to examine the clinicopathological features and epidemiology of primary gastric lymphoma in Jordan as a model for Middle East countries where such data is scarce. From 1991--2002, 219 patients with primary gastric malignancy were managed at our hospitals. Among these there were 19 patients with primary gastric lymphoma. Pertinent data for these patients were analyzed. Primary gastric lymphoma constituted 65.5% of all gastrointestinal lymphoma and 8.7% of all gastric malignancies. Male-to-female ratio was 2.8:1. The mean age was 56 years (range 39--82). The incidence was 0.6/100,000. The proximal third was the most common localisation. Abdominal pain was the commonest presentation. Low-grade MALT lymphomas, high-grade MALT lymphomas, diffuse large cell B lymphomas and T cell lymphoma were found in 21.1, 26.3, 47.4 and 5.3%, respectively. Nine patients had gastrectomy followed by chemotherapy, 6 patients had palliative resection, 3 patients had chemotherapy only and the remaining patient was treated with Helicobacter pylori eradication. The mean follow-up for all patients was 42.2 months. The 5-year survival rates for stages IE (n=5), IIE (n=4), IIIE (n=6) and IVE (n=4) were 100, 67, 27 and 0%, respectively (p=0.0003). The overall 5 years survival was 48.2%. Primary gastric lymphoma in Jordan shares some epidemiological features with western disease. Jordanian patients are detected and treated after a relatively long delay. Advanced stage at diagnosis correlated with poor outcome. There is a need of an earlier diagnosis and subsequent better care.

Spontaneous Anterior Tibial Artery Avulsion and Tibio-Peroneal Trunk Transection Resulting into a Pseudoaneurysm: A Case Report

Patient: Female, 53 Final Diagnosis: Spontaneous non-traumatic anterior tibial artery avulsion and tibio-peroneal trunk transection Symptoms: Pain Medication: — Clinical Procedure: Autogenous popliteal-tibioperoneal trunk bypass Specialty: Surgery Objective: Rare disease Background: Popliteal fossa pseudoaneurysms as a result of trauma are not uncommon. However, spontaneous pseudoaneurysms as a result of non-traumatic rupture of posterior tibial artery (PTA), anterior tibial artery (ATA), or tibioperoneal trunk (TPT) artery segment are extremely rare. We report a case of spontaneous popliteal fossa pseudoaneurysm resulting from spontaneous avulsion of the ATA and transection of the TPT. Despite a thorough workup, no underlying associated disease was found. The extreme rarity of this disease presentation prompted us to report this case. Case Report: A 53-year-old female patient presented with a 10-day history of sudden onset of non-traumatic left popliteal fossa pain and swelling. A popliteal fossa pseudoaneurysm was diagnosed by duplex ultrasound examination. Computed tomography angiography (CTA) was performed to confirm the diagnosis and to plan treatment. Surgical exploration revealed avulsion of the ATA and transection of the TPT leading to a pseudoaneurysm. Autogenous popliteal-tibioperoneal trunk bypass was performed with uneventful recovery. Conclusions: A spontaneous popliteal fossa pseudoaneurysm caused by non-traumatic ATA avulsion and complete transection of TPT is extremely rare. Yet, it can be the cause of limb loss if not recognized early and treated promptly. Awareness by the medical community will help reduce the potential morbidity associated with this condition.
