Clinical and pathological characteristics of abdominal ectopic spleen: 13 cases report / 解放军医学杂志

Objective To analyze the clinical manifestation, diagnosis and pathological features of abdominal ectopic spleen (AES) cases. Methods The clinical and pathological characteristics were retrospectively analyzed along with the followup data of patients diagnosed as AES in the Changhai Hospital affiliated to Naval Medical University from Jan. 2013 to Dec. 2018. Results A total of 13 cases of AES were diagnosed, of whom 7 cases (53.8%) were found due to medical examination, and only one case was diagnosed before operation, while the rest were considered as having tumor of the abdominal organ near the mass. Out of the 13 cases, the AES in 6 cases were located at the pancreas tail. The surgical excision samples showed an appearance of nodular lesion with clear contour, and the structure of spleen parenchyma could be identified under microscope. Among the 13 cases, spleen trabecular and obvious central arterioles were absent in 2 cases with history of surgery, while the rest 11 cases shared the pathological features of spleen trabecular, central arterioles and secondary follicles. All the 13 patients survived except one died due to progression of gastric cancer and another one missing of follow-up. Conclusions The AES lacks specific clinical features, which requires antidiastole with abdominal tumors. It is inferred from clinicopathological features that splenosis may differ from accessory spleen, that is, splenosis may lack typical spleen white pulp.

Bazo errante gigante con torsión del pedículo e infarto esplénico: reporte de un caso / Giant Wandering Spleen with torsion of the pedicle and splenic infarction: a case report

INTRODUCCIÓN: El bazo errante, es una entidad clínica poco común. Su espectro clínico varía desde enfermedad asintomática hasta complicaciones asociadas y su manejo es predominantemente quirúrgico. CASO CLÍNICO: Hombre, con cuadro clínico de dolor y masa abdominal palpable, con hallazgos tomográficos sugestivos de patología con asiento en retroperitoneo, con obstrucción intestinal secundaria; por laparotomía se identifica de forma incidental bazo ectópico solo fijado a través de pedículo vascular torsionado y signos de hipertensión portal, realizándose esplenectomía. CONCLUSIONES: La torsión esplénica es la complicación más frecuente del bazo errante, una entidad bastante rara con muy pocos casos publicados en Colombia.

BACKGROUND: The wandering spleen is an uncommon clinical entity. Its clinical spectrum varies from asymptomatic disease to associated complications and its management is predominantly by surgery. CLINICAL CASE: Man with clinical picture of pain and palpable abdominal mass, with tomographic findings suggestive of pathology with retroperitoneal seating, with secondary intestinal obstruction; by laparotomy incidentally, an ectopic spleen is identified, only fixed through a torsioned vascular pedicle and signs of portal hypertension, performing splenectomy. CONCLUSIONS: Splenic torsion is the most frequent complication of the errant spleen, a very rare entity with very few cases published in Colombia.

Abdomen agudo secundario a torsión de bazo ectópico como causa inusual de dolor abdominal en urgencias / Acute Abdomen After Ectopic Spleen Torsion as an Unusual Cause of Abdominal Pain in the Emergency Department

RESUMEN El bazo ectópico es una enfermedad infrecuente, que se caracteriza por el aumento de la movilidad del bazo debido a la ausencia o laxitud de sus ligamentos suspensorios, lo que puede dar lugar a una torsión de su pedículo, y provocar un abdomen agudo. Se presenta el caso de una mujer de 29 años que acude al servicio de urgencias por presentar dolor abdominal de 7 meses de evolución, localizado en fosa ilíaca izquierda, que ha empeorado en las últimas 48 horas. Se realizó ecografía en el servicio de urgencias (point-of-care) que mostró una imagen compatible con bazo ectópico junto a su hilio, localizado en tercio inferior del abdomen cerca de la vejiga y del útero, y líquido libre. La tomografía axial computarizada confirmó el diagnóstico de torsión del pedículo. Se realizó laparotomía de urgencia y se localizó el bazo dentro de la pelvis con torsión del pedículo; ante un bazo no viable se realizó esplenectomía. La histología demostró cambios trombóticos difusos con infartos isquémicos y hemorrágicos del bazo. A pesar de su baja prevalencia, el bazo ectópico se debe tener en cuenta a la hora de realizar el diagnóstico diferencial en aquellas mujeres en edad fértil que consultan por dolor abdominal o masa pélvica(AU)

ABSTRACT Ectopic spleen is a rare disease, characterized by increased mobility of the spleen due to the absence or laxity of its suspensory ligaments, which can lead to torsion of its pedicle and cause acute abdomen. We present the case of a 29-year-old woman who attends the emergency department with abdominal pain of seven months of evolution and located in the left iliac fossa, which has worsened in the last 48 hours. An ultrasound was performed in the emergency department (point-of-care), which showed, next to its hilum, an image consistent with ectopic spleen, located in the lower third of the abdomen near the bladder and uterus, and free fluid. Computed axial tomography confirmed the diagnosis of pedicle torsion. Emergency laparotomy was performed and the spleen was located inside the pelvis with torsion of the pedicle. Splenectomy was performed before a non-viable spleen. Histology showed diffuse thrombotic changes with ischemic and hemorrhagic infarcts of the spleen. Despite its low prevalence, the ectopic spleen should be taken into account when making the differential diagnosis in those women at childbearing age who come to the clinic for abdominal pain or pelvic mass(AU)

Ectopic Spleen Presenting as Abdominal Mass: A Case Report.

Ectopic spleens are rare findings though spelenincule are common. It is due to failure of fusion of mesogastrium and the lining body wall epithelium, resulting in supports of the spleen become lax, and spleen position will be abnormally located. Hypermobile colon and prune belly syndrome are associated with the ectopic spleen. This is more common in children. In adults, it is more common in woman; especially in multipara. A rare case of mass per abdomen in right iliac fossa, turned out to be functional spleen with aneurysm of splenic artery is presented. There were no features of infarction, torsion or portal hypertension or splenic vein thrombosis. Splenectomy was done. The patient had uneventful recovery.
