“…Preoperative liver biopsy can further confirm the diagnosis but it is not routinely done in patients with liver cysts. Immuno-histological staining is usually positive for p63, p16 CK5/6 as reported in literature [11] . The biopsy of our patient was positive for p63 and p16.…”

“…One such case, reported by Bacha et al, demonstrated the presence of atypical squamous cells with irregular nuclei, keratinization, and mitoses on bile duct brushing cytology. 23 Squamous cells may also infrequently be seen in pancreatic aspirates, which are sometimes obtained simultaneously with biliary brushings. Olson et al reported that squamous cells were found in 2.5% of pancreatic fine needle aspiration specimens in a review of 4094 specimens.…”

Squamous cells are rarely found in biliary tract cytology specimens, and when present are typically scant in quantity. Over an 8‐year time period, two cases at our institution reporting abundant squamous cells were identified. Both patients underwent endoscopic retrograde cholangiopancreatography with bile duct brushings and removal of a migrated biliary stent. The migrated stents were retrieved using rat toothed forceps and required removal of the endoscope through the esophagus with the stent exposed to esophageal and oral mucosa outside of the endoscope. Cytologic examination of the accompanying biliary stent material accordingly revealed abundant benign squamous cells. However, bile duct brushings showed benign ductal epithelial cells without squamous cells. Prior and subsequent cytology and bile duct surgical pathology specimens did not show squamous metaplasia. Migrated biliary stents that require endoscopic withdrawal increase the risk of contaminating samples with squamous cells. Recognition of this unique scenario is important, as the differential diagnosis includes squamous metaplasia and squamous neoplasia.

“… 1 Metastatic disease is uncommon but has been reported in a few cases, most notably with hepatic lesions, which were seen in our patient. 9 The overall prognosis is poor, partly because of its difficult diagnosis and often late presentation because of vague symptomatology. 1 , 4 , 10 Currently, there is no standard therapy, but treatment options depend on the extent of disease.…”
