“…Focal accumulations of elastic fibers in the GIT are usually accompanied by a variable amount of fibrous connective tissue and show ill-defined margins. They can form focal, bifocal, or multifocal masses that may simulate polyps, ulcers, or neoplasms [ 3 , 9 , 14 , 15 ]. All these elastotic deposits do not tend to calcify.…”

“…These elastic accumulations can be observed anywhere between the oral cavity [ 1 , 2 ] and anus [ 3 , 4 , 5 , 6 , 7 , 8 ]. They may present as polyps [ 5 ], extensive, ill-defined, non-polyp-forming deposits [ 8 ], or pseudoneoplastic accumulations of elastic fibers [ 9 ]. Exceptionally, fibroelastotic lesions have been described in intra-abdominal solid organs, such as the liver [ 10 ] or pancreas [ 11 , 12 ] with a nodular or pseudotumoral appearance.…”

Abdominal elastotic deposits are uncommon lesions that often presents as polyps. They show three histological patterns: fibroelastosis, angioelastosis, and elastofibroma. We describe 23 cases including rare locations, such as mesentery, greater omentum, hernia sac, spleen, peripancreatic fat, and hypodermal fat. The age of the patients ranged from 49 to 93 years (mean, 76.8 years). Most lesions were discovered incidentally in the microscopic study. The most frequent locations were peritoneal subserosa (43.5%) and mesentery/mesocolon/greater omentum (39.1%). The most common pattern was fibroelastosis (69.6%) followed by angioelastosis (26.1%). We observed one case of omental elastofibroma. A review of the 14 abdominal elastofibromas described including our case revealed that the age of the patients ranged from 45 to 88 years (mean, 68.5 years). Female predominance is striking (M:F, 1:12). The most common site was the stomach (50%). The greater omentum (14.3%), small intestine (7.1%), and pancreas (7.1%) are very rare sites for this lesion. Only one case before ours has been published in the greater omentum. The size of the lesions ranged from 0.7 cm to 8 cm (mean 3.2 cm). In 36.4% of the cases located in the digestive tract, the mucosa did not show alterations. Ulcerations (36.4%) or polypoid excrescences (18.2%) were mostly observed. Six (42.9%) cases were asymptomatic and six (42.9%) cases simulated a neoplasm. Two cases were associated with elastofibromas in other locations. Differential diagnosis includes amyloidoma, elastofibrolipoma, mesenteric elastic vascular sclerosis in neuroendocrine tumors, diverticular disease elastosis, pseudoxanthoma elasticum, pulse granuloma, and digestive lesions in patients treated with D-Penicillamine.
