“…An accessory spleen is defined as ectopic splenic tissue that due to the failure of cell fusion during embryonic development while migrating from the midline to the left upper quadrant [ 7 , 8 ]. An accessory spleen includes isolated spleen tissue outside the normal spleen [ 9 , 10 ], usually located in the splenic hilum and the tail of the pancreas, but occasionally in the greater omentum and gastrointestinal tract [ 11 ]. An ectopic accessory spleen in the stomach is relatively rare which is usually asymptomatic and incidentally discovered.…”

Background The accessory spleen has no anatomical or vascular relationship with the normal spleen, The tissue structure and physiological function of the accessory spleen are the same as those of the normal spleen, which usually locate in the splenic hilum and the tail of the pancreas. The aims of this manuscript are to present a rare case of the gastric accessory spleen and a review of the literature. Case presentation A 19-year-old male patient was sent to the emergency department with stomach bleeding after drinking alcohol. The computed tomographic scan showed a 1.2 cm × 1.7 cm mass at the lesser curvature of the gastric fundus. Gastrointestinal endoscopy displayed a submucosal elevated lesion on the gastric fundus, and gastrectomy was performed. Postoperative pathological examination proved an accessory spleen in the stomach. The postoperative course was uneventful, and the patient was discharged on the 6th day after the surgery. Conclusions The accessory spleen at the fundus of stomach is extremely rare, especially in this case, which is accompanied by acute gastric bleeding, and it is difficult to diagnosis before operation. Many literatures reported that it was misdiagnosis as tumor, so it is necessary to diagnose accessory spleen correctly.

“…An accessory spleen occurs when splenic tissue is in a separate body region, which occurs in up to 15% of the population [ 1 ]. The most common locations for accessory spleens are in the splenic hilum (80%) and the pancreatic tail (17%) [ 2 - 5 ]. However, they can also be located within the greater omentum and gastrointestinal tract [ 2 ].…”

“…The congenital etiology occurs during the fifth week of fetal development from a failed fusion of the splenic anlage [ 7 ]. Splenosis is the process of autologous transplantation of the spleen after splenectomy [ 2 ]. It can present as numerous nodules and have compensatory hypertrophy reaching up to 5 cm [ 3 , 4 ].…”

Accessory Spleen: A Rare and Incidental Finding in the Stomach Wall

An accessory spleen is splenic tissue located separately from the anatomical location of the spleen and is a rare phenomenon. It can be found within the gastrointestinal tract. Clinically, accessory spleens are benign but can be misidentified as reactive lymph nodes or malignant gastrointestinal tumors. They are often diagnosed via endoscopy or imaging. We report the case of a woman presenting with iron deficiency anemia who was incidentally noted to have a gastric submucosal lesion with pathology significant for accessory spleen. As this case illustrates, when submucosal lesions are present in the stomach, especially in patients with a history of splenectomy, the endoscopic ultrasound (EUS) operator should consider the possible presence of an accessory spleen to minimize invasive removal procedures.

Purpose The accessory spleen is quite a common abdominal anomaly. However, the traumatic accessory spleen rupture is an extremely rare condition requiring surgical intervention, even laparotomy. 9 cases of traumatic accessory spleen were found published between 1962 and 2022. The study aims to evaluate traumatic accessory spleen rupture cases regarding their causes, clinical course, and possible diagnosis without surgery and treatment. Methods Desk research method using available online databases. Descriptive methods were employed to analyze the collected data. The results are summarized in the Table concerning gender, age, injury details, accessory spleen injury characteristics, treatment, and others such as previous splenectomy or primary spleen involvement in injury or accompanying abdominal injuries. Results In total, there were 9 cases of traumatic accessory spleen, of which 2 were managed conservatively and the remaining 7 were treated operatively. All the patients survived. One-third of all included patients already had their primary spleen removed, which facilitated the diagnosis of traumatic rupture of an accessory spleen. The proper diagnosis of an accessory spleen rupture was concluded in 2 cases and confirmed in surgery. Conclusion The recognition of the traumatic rupture of an accessory spleen before surgery is challenging but can be made easier if the patient underwent splenectomy before. The traumatic accessory spleen rupture does not coexist with an injury of a primary spleen.
