Abstract
BackgroundPrimary cystic neoplasms of the peritoneum are rare lesions and not commonly encountered in practice. Many intra-abdominal processes may mimic cystic masses within the peritoneal cavity and pose a diagnostic challenge to both the pathologist and radiologist. Clinical presentation is diverse and varied. These lesions are usually benign. Hence complete surgical excision is the treatment of choice in most of the cases.MethodsStudy design: Descriptive Retrospective study.Cystic peritoneal lesions were identified and studied from data over a period of 5 years in the Histopathology Section at a tertiary care hospital in Pune, India. Mode of presentation, imaging findings in addition to gross and histopathologic findings of these lesions were studied.ResultsOut of 50 peritoneal lesions studied over a period of 5 years, only 7 were identified to be cystic peritoneal masses.Of these two were found to be peritoneal cysts, two mesenteric cysts, one an infected mesenteric cyst and one each a mucinous cystadenoma and lymphangioma.ConclusionsCorrect diagnosis rests in the hands of the pathologist and ensures that the patient receives appropriate and timely management. Hence knowledge of the spectrum of these rare cystic peritoneal masses is necessary to distinguish from other potential cystic abdominal mimicker masses and avoid a potential pitfall.
Highlights
Primary cystic neoplasms of the peritoneum are uncommon lesions, rarely encountered in daily practice. (Liew et al, 1994) Most of these lesions present with vague complaints of abdominal pain and nausea

These include the various fluid collections such as abscesses, seroma, biloma, urinoma, or lymphoceles. These are often recognized based on relevant clinical history like recent surgery or trauma. (Arraiza et al, 2015) Cystic peritoneal masses may be localized anywhere in the mesentery, from duodenum to rectum, these are mostly found in the ileum and right colon mesentery. (Huis et al, 2002) Complete surgical excision of the cyst is usually the treatment of choice, with no recurrence post excision. (Pithawa et al, 2014) knowledge of the spectrum of these rare cystic peritoneal masses is necessary to distinguish from other potential cystic abdominal mimicker masses and avoid a potential pitfall.
