Accessory Spleens

Accessory spleens are one or more areas of normal ectopic splenic tissue of variable size supplied by the branches of the splenic artery. A 7 year-old mixed breed male dog was fixed for use as a model in anatomy hall. During the abdominal dissection, the gross examination showed a 6.3×3.1×1 cm mass that was situated on the caudodorsal border of the spleen. Its appearance and firm consistency were similar to those of spleen. There was no connection between the spleen and this mass. It was supplied by accessory splenic artery. Microscopic examination of the mass revealed some structures similar to spleen.

Controversy continues to exist regarding the routine histologic examining of tonsillectomy specimens. Proponents suggest that among other reasons, missing an important diagnosis such as occult malignancy or granulomatous disease and possible medicolegal consequences argue in favor of routine histologic examination. Others state that we should consider the very low yield of significant histologic findings in routine tonsillectomy specimens and its added cost. We performed a retrospective evaluation of all cases of patients who underwent tonsillectomy with or without adenoidectomy between January 1992 and July 1996. Two hundred eighty-eight charts were evaluable. Group 1 consisted of all tonsillectomy specimens that were subjected to gross examination only. Group 2 consisted of all tonsillectomy specimens that were subjected to gross examination as well as microscopic examination. In group 1, no abnormal gross findings were noted. Group 2 consisted of specimens from an older population with a mean age of 21.6 years. There were 43 patients older than 20 years old in group 2, and in all cases except four the preoperative clinical impression correlated with the microscopic findings. Occult malignancy was found in only one of these four patients. No cases of granulomatous disease were discovered. Overall, no patients except one had any change in postoperative treatment on the basis of the results of microscopic examination. We believe that routine microscopic examination of tonsillectomy specimens results in unnecessary cost and consumption of resources and time. Microscopic examination should be done in only selected cases such as in patients with grossly asymmetric tonsils or in patients with a history of malignancy.

Accessory Spleens

Splenectomy has been performed in trauma in a number of benign lesions of the spleen and in a certain haematological diseases. When performed for trauma a luxation technique of splenectomy is applied since it allows quick haemostasis. When performed in other indications, the spleen is usually enlarged. In those patients "splenectomy in situ" is recommended. That means, first, division of the short gastric vessels and gastrosplenic ligament, second, ligation of the splenic artery and finally division of the hilar vessels after which the spleen may be simply removed. Details of operative technique, management of accessory spleens and prevention of operative complications are described.

Accessory Spleens

Accessory spleens, which are also known as a splenunculus or a splenule, are a benign developmental anomaly in which nodules of splenic tissue exist separate to the main body of the spleen. It is a reasonably common phenomenon which is present in approximately 10-30% of the population, however they only infrequently become symptomatic. Torsion of an accessory spleen is a rare cause of abdominal pain with few cases reported in the literature, most commonly in the paediatric population. Without treatment, torsion can lead to significant complications including haemorrhagic shock, peritonitis or rupture. The rarity portends a diagnostic challenge and thus a high index of suspicion is crucial for attaining a prompt diagnosis and timely management. This case gives an account of a 43-year-old female who presented with abdominal pain secondary to a torted accessory spleen.

Microscopic Findings

Introduction. The existence of proteinuria may be overlooked by applying the test strips. The aim of this study has been to determine the discrepancy between the findings of proteinuria detected by test strips when compared to the results of its testing with the sulfosalicylic acid. Material and Methods. The study sample consisted of 1106 subjects, who were divided into the proteinuria positive (test strips showed the presence of isolated proteinuria), and proteinuria negative group (microscopic examination revealed the presence of >10 fresh red blood cells/?L, and/or >1 dysmorphic erythrocyte/?L, and/or >10 leukocytes/?L, and/or> 1 cylinder, and/or >1 nonsquamous epithelial cells/?L, and/or >100 bacteria/?L). Both groups had the urine tested with sulfosalicylic acid. The chemical and microscopic examination of the urine was done by the analyzer LabUMat-UriSed. Results. Proteinuria was confirmed with the sulfosalicylic acid test in 96.5% of subjects from group 1 and in 85.3% of subjects from group 2. Among the patients with the negative finding of proteinuria on the test strip and with the positive sulfosalicylic acid test there was a significantly higher number of those with pathological findings of erythrocytes, leukocytes, bacteria and cylinders in the urine when compared to those of the same group with negative sulfosalicylic acid test. Conclusion. Sulfosalicylic acid test should be performed in cases of pathological microscopic findings in the urine in case of the presence of >10 fresh erythrocytes/?L and/or >1 dysmorphic eryth?rocyte/?L and/or >10 leukocytes/?L and/or >1 cylinder (except hya?line) and/or >1 nonsquamous epithelial cells/?L and/or >100 bacteria/?L even if the test strip examination is negative for proteinuria.

Unusual Case Report

The authors report a case of thoracic splenosis, which is the autotransplantation of splenic tissue into the pleural cavity. Splenosis in the chest is a rare entity and most often an incidental finding on chest computed tomography, typically showing solitary or multiple well-defined, noncalcified pleural nodules of variable size in the left hemithorax. It is important to include this benign pathology in the differential diagnosis among other, generally malignant, pleural lesions. Imaging clues to the diagnosis are absence of the spleen and/or associated rib fractures. Early identification of thoracic splenosis as a cause of pleural nodules can prevent unnecessary and risky invasive procedures, such as biopsy or surgery.

Gross Examination

The authors report the case of an inflammatory pseudotumor found incidentally in the spleen of a 53-year-old woman who had undergone splenectomy for the treatment of immune thrombocytopenic purpura. An ultrasound performed 2 months prior to the operation showed a spleen of normal size with no appreciable masses; however, gross examination of morselized splenic tissue removed by laparoscopic splenectomy revealed two small, well-circumscribed, white–tan nodules measuring 0.8 and 1.5 cm admixed with otherwise normal-appearing splenic parenchyma. Microscopically, these mass lesions were inflammatory pseudotumors composed of a variable mixture of polyclonal populations of mature lymphocytes and plasma cells with eosinophils, neutrophils, histiocytes, and fibrous tissue. This case represents a rare splenic lesion in our review of the world literature. Inflammatory pseudotumors of the spleen are usually solitary, often asymptomatic, rarely diagnosed prior to surgical removal, and characterized by a varied but uniformly benign histologic appearance. Recognition of this entity by clinicians and pathologists is important in definitively ruling out malignancy of the spleen.

We report a case of acute hemorrhagic leukoencephalitis in an adult man with a prodrome of “feeling unwell” two days prior to this death. At autopsy, external examination revealed minor external injuries including contusions on the scalp and left thigh and abrasions on the forehead and right eyebrow. Gross examination of the brain after coronal sectioning revealed multiple petechial hemorrhages in the white matter in the cerebral hemispheres, corpus callosum, basal ganglia, brainstem, and cerebellum. Microscopic examination of these lesions revealed demyelination, hemorrhage, and necrosis with fibrin exudation in a perivenular distribution with radial extension into the white matter. The remainder of the autopsy was unremarkable. This case highlights the death of a young man by a rare fatal complication of a natural disease only identified by a singular set of gross and microscopic findings at autopsy in circumstances that would otherwise suggest a nonnatural death. The case demonstrates the importance of a thorough autopsy in settings where the clinical history, scene, and circumstances may be misleading or absent.

AbstractGanglioneuromatosis is a rare disorder characterized by hyperplasia of intestinal ganglia including myenteric plexus and enteric nerve fibers. This disorder is generally described in children, but sporadic cases have also been described in adults. Most human cases arise in the colon and rectum. The disorder has also been described in dogs, mostly juveniles, but rarely in mature dogs with the oldest dog reported with this change being 9 years old.We report the first case in an older dog from Croatia. A 13-year old female, mixed-breed dog had a history of diarrhea and weight loss. Ultrasound revealed focally-extensive markedly thickened small intestine. The changed part of the intestine, measuring 7 mm x 20 mm, was removed on laparotomy and delivered for histopathologic examination. Grossly, the intestine showed circumferential expansion of the intestinal wall, which was whitish in color. Microscopic findings included diffuse hyperplasia of the myenteric and submucous plexus. Focally in the affected tissue a subacute ulcer was evident, which was probably not the cause of intestinal signs, as it presented a localized lesion, while ganglioneuromatosis was a diffuse change in the affected tissue.So far, ganglioneuromatosis was reported in young dogs, rarely in adult dogs. Our report shows that ganglioneuromatosis can also be encountered in older dogs. Although the lesion presents a rare finding, it should be listed as a differential diagnosis in dogs where infectious and neoplastic etiology has been ruled out as cause of diarrhea.
