Gastric pseudolipomatosis, usual or unusual Re-evaluation of 909 endoscopic gastric biopsies

Abstract

Microvesicular pneumatosis intestinalis, also called "pseudolipomatosis" for resembling fatty infiltration, is characterized by the presence of small gas voids in the gastrointestinal wall, especially in mucosa. These voids are not lined with epithelia. There are few reported cases about colon, duodenum and skin. Because there is only one case report about pseudolipomatosis in the stomach, we reevaluated 909 endoscopic biopsies taken from gastric corpus to check the presence of pseudolipomatosis. We determined pseudolipomatosis foci in 3 percent (n=27) of biopsies. In two cases there were pseudolipomatosis foci in endoscopic biopsies having otherwise normal histologic findings, while there were pseudolipomatosis foci in endoscopic biopsies of 25 patients with gastritis. Helicobacter pylori was found in 85 % of biopsies having pseudolipomatosis foci. In this study, we presented some histopathologic characteristics of pseudolipomatosis seen in gastric mucosa.Alper M, Akcan Y, Belenli OK, Çukur S, Aksoy KA, Suna M.

Dermal vacuoles in two biopsies of psoriasis

“…The authors coined the term ‘pseudolipomatosis cutis’ for this histological alteration and accepted it as equivalent to insufflation‐induced vacuolization of the colonic mucosa (i.e. mucosal pseudolipomatosis of the colon) 1,4 . However, due to the paucity of pertinent studies, whether these dermal spaces represent simple empty vacuoles or endogeneous/exogeneous fat globules has not yet been clarified 2 …”

Pseudolipomatose do cólon: relato de caso

“…1 Apresenta etiologia incerta acreditando-se que possa ocorrer em conseqüência à infiltração de ar na parede intestinal, a partir de solu-ções de continuidade na mucosa cólica ocasionadas por traumatismos durante a realização do procedimento endoscópico. 1,2,6,8 A enfermidade também ocorre no estômago e duodeno apresentando prevalência estimada de 0,02 a 1,7% dos exames endoscópicos. 5 Estima-se que existam pouco mais de 60 casos publicados de pseudolipomatose acometendo o cólon.…”
