“…After the neck and oral cavity, the most frequent sites reported in the literature are the pancreas and thyroid gland. Pancreatic lesions are also believed to be benign epithelial inclusions embedded within the pancreas during embryogenesis 30) . OLCs are rare cystic lesions lined with stratified squamous epithelium surrounded by lymphoid tissue and have been reported as branchial cysts, branchial cleft cysts, branchiogenic cysts, or pseudocysts 3) .…”

Lymphoepithelial cyst of the oral cavity is a rare cystic lesion that presents as an asymptomatic, well-circumscribed, yellowish small submucosal nodule covered by normal overlying mucosa, usually located in the floor of the mouth or in the ventral or posterolateral surface of the tongue. Histopathological examination reveals a cyst lined by a stratified squamous epithelium surrounded by lymphoid tissue. In this paper, we report two cases of oral lymphoepithelial cyst, one on the anterior floor of the mouth and another on the posterior lateral tongue. In both cases, the patients were women aged approximately 50 years and the lesions were treated by local surgical excision, with no evidence of recurrence after 2 years of follow-up.

“…The traditional markers such as CEA, CA19-9, CA-125, and fluid viscosity would be expected to be significantly lower in LEC than in mucinous neoplasms [25,26]. Only few cases presented with elevated serum levels of CA 19-9 [17,26,32].…”

Lymphoepithelial Cyst of the Pancreas: A Rare Case Report and Review of Literature

Lymphoepithelial cysts are rare pancreatic lesions of undetermined pathogenesis. The literature on this entity is limited to case reports or small series. We describe a case of 66 year male, incidentally diagnosed as lymphoepithelial cyst of pancreas that was managed by enucleation. This is the first case report of lymphoepithelial cyst from India. An extensive Medline search was carried out for lymphoepithelial cyst of pancreas. Till date less than 100 cases were identified in available literature. All these cases (including our case) were analyzed. This entity has uniform and distinctive clinicopathological features. About half of the reported cases were asymptomatic with most of the lesions diagnosed incidentally. Majority of patients presents with non-specific symptoms making preoperative diagnosis difficult. Lymphoepithelial cyst of the pancreas is a rare benign lesion, which is difficult to diagnose preoperatively. High index of suspicion and preoperative fine needle aspiration cytology may help in making diagnosis and avoiding surgery in asymptomatic patients.

“…Despite the improvement in imaging modalities and the increased expertise in cytologic assessment of pancreatic cystic lesions, preoperative differentiation of a benign versus a malignant lesion still cannot be carried out with accuracy and the final diagnosis can only be achieved after resection. 9 Regardless of the findings on cross-sectional imaging and FNA biopsy, raised serum CA19-9 in association with a pancreatic mass (as in our patient) creates a diagnostic and management dilemma which cannot be resolved without surgical resection.…”

“…8 The size of the cyst varies from 1.2 to 17 cm (mean, 4.6 cm). 9 Our patient was a 43-year-old man. The wider use of imaging in recent years has been associated with an increase in reported cases 10 particularly that some 40% of LECs of the pancreas are asymptomatic.…”

Lymphoepithelial cysts (LECs) of the pancreas are rare true pancreatic cysts. Their cause is not known. The differential diagnosis is broad and includes many benign and malignant cystic lesions of the pancreas and surrounding organs. A combination of imaging modalities and fine needle aspiration might narrow the differential diagnosis. However, the final diagnosis can only be achieved with certainty after resection of the cyst. In this study, we report the largest LEC of the pancreas to have been resected laparoscopically. A 43-year-old man presented with upper abdominal pain, a 7.5 cm mutlioculated cystic mass in the pancreatic body and tail on imaging, and a raised serum cancer antigen-19-9. Laparoscopic distal pancreatectomy and splenectomy was performed. Histologic examination revealed a LEC. This study discusses the diagnostic difficulties and management decisions which face surgeons treating pancreatic cysts.
