Primary Omental Lipoma in a Child: A Case Report and Literature Review

2022

BackgroundLipoma is a common benign tumor derived from adipose tissue, with an incidence of nearly 10%. It is the most common mesenchymal tumor throughout the body. However, the pathogenesis of lipoma is not clear yet, and the increased incidence is attributable to obesity, elevated serum cholesterol, diabetes, trauma, radiation, familial predisposition, and chromosome. Primary omental tumor is a rare lipoma occurring in the greater omentum, most of which is reported in the form of clinical case reports. Nevertheless, primary omental tumor is even rarer in children. To date, there have been few reports of clinical cases.Case PresentationWe report a rare case of primary omental lipoma in a 6-year-old boy. After an accidental fall, a CT scan found that he had a tumor in the left upper abdomen. He had no history of abdominal pain, abdominal mass, vomiting, etc. The boy was admitted to the hospital within 3 days, and was diagnosed with an intra-abdominal tumor. After admission, abdominal ultrasound and enhanced CT showed a 71 ×40 ×60 mm mass in the left middle abdomen, which was considered a lipoma. There was no abnormality in tumor markers. Through laparoscopic surgery, intraoperative exploration revealed that the tumor was located in the left mid-upper abdomen, and was yellow, solid, soft, and isolated. The intraoperative diagnosis was an omental lipoma. We used an ultrasonic knife to resect the omentum close to the base of the tumor. The tumor was completely resected, put in a retrieval bag and sealed. Finally, the left and right sides of the umbilical incision were extended to take out the tumor tissue. The child received liquid food 6 h after the operation and was discharged 3 days later. The postoperative pathological diagnosis was an omental lipoma. He was seen at follow-up 3 months after discharge and had no complaints, an abnominal ultrasound showed no tumor recurrence.ConclusionPrimary omental lipoma in children is a rare benign tumor of the omentum. Its etiology and pathology are not clear. US, CT, and MRI can facilitate clinical diagnosis and preoperative evaluation. Laparoscopic surgery is an effective treatment, and the prognosis of children is favorable. This case is beneficial to improve the clinical knowledge of pediatric surgeons about this rare disease.

A Giant Childhood Mesenteric Lipoblastoma With Extensive Maturation

et al. 2020

Abdominal lipoblastomas are uncommon soft tissue tumors in children and rarely arise from the mesentery. Due to intraabdominal location and slow growth, these masses can go unnoticed for long periods of time and often found on surgical exploration. We present a case of a 12-year-old male with years of abdominal distension accompanied by new onset early satiety that was found to have an intra-abdominal mass. He underwent an exploratory laparotomy revealing a large 33 x 27 x 15 cm rubbery mesenteric mass displacing the entire intra-abdominal contents, connected by a single vascular pedicle and encasing a loop of small intestine. The mass was resected and the patient did well without signs of recurrence. Histology confirmed the presence of mature adipocytes but on further cytogenetic analysis, a translocation between chromosomes 2 and 8 at the 12q arm was detected, which is often associated with lipoblastomas. This case represents the one of the largest mesenteric lipoblastomas that matured extensively to lipoma-like histology at the time of surgical resection.

“…It is a soft and mobile mass that does not infiltrate surrounding structures, and as a result, it mostly remains asymptomatic [2]. However, in case the tumor reaches a large size, it may cause variable symptoms [3]. Imaging plays a critical role in diagnosis and treatment planning when a symptomatic fat-containing mass is encountered.…”

Mesenteric lipoma as the cause of intermittent abdominal pain

Mesenteric lipomas are extremely rare lesions with about 50 cases described in the current literature. It is a soft and mobile mass that does not infiltrate surrounding structures, and as a result, it mostly remains asymptomatic. However, in case the tumor reaches a large size, it may cause variable symptoms. Magnetic resonance imaging techniques are highly sensitive in characterizing fat-containing masses, including lipoma. Herein, we present a 58-year-old lady who presented with intermittent abdominal pain due to a mesenteric lipoma, but the diagnosis was delayed because of a series of errors in clinical and radiological evaluations.
