Lymphangiomas are benign neoplasias of lymphatic tissue, extremely rare in the pancreas. Three lymphangioma types exist: capillary, cavernous and cystic. The authors report a case of cystic lymphangioma of the pancreas, with incidental diagnosis to the abdominal ultrasonography on investigation of urinary symptoms in male patient. To the laparotomy upper cystic mass was identified in the pancreas, that was totally resected. The histological examination demonstrated a cystic lymphangioma of the pancreas. The cystic lymphangioma of the pancreas was discovered accidentally, being assintomatic in most of the cases. Treatment of choice is complete resection, otherwise recidive is higher than 50%.

Apresentação de um caso de cisto esplênico epidermóide em paciente masculino de 13 anos, que apresentou diminuição do apetite, febre e vômitos pós-alimentares e massa abdominal palpável ao exame físico. A ultra-sonografia abdominal demonstrou lesão expansiva na topografia do baço e a tomografia computadorizada revelou lesão homogênea intrínseca do órgão, sem comunicação com pâncreas. À laparotomia observou-se massa cística de grande extensão, realizando-se esplenectomia total, sendo diagnosticado no exame anatomopatológico cisto epidermóide de baço. O paciente evoluiu com desaparecimento dos sintomas. Os cistos esplênicos epidermóides são raros, podendo ser vistos principalmente em crianças e adultos jovens, o que propõe uma origem congênita para esta doença.

The authors present a case of epidermoid splenic cyst in masculine patient of 13 years, that presented decrease of appetite, fever and alimentary vomits and tangible abdominal mass in the physical exam. Abdominal ultrassonography demonstrated expansible lesion in the topography of the spleen, and computerized tomography revealed intrinsic homogeneous lesion of the spleen, without communication with pancreas. To the laparotomy, cystic mass of great extension was observed, submited total esplenectomy, being diagnosed in the histopatological exam epidermoid splenic cystic. In the follow-up patient developed with disappearance of the symptoms. The epidermoid splenic cyst are rare, they can be seen mainly in children and young adults, what proposes a congenital origin for this disease.

The authors present a rare case of pathology from spleen, a nonparasitic, non-neoplastic splenic cyst, in an adult male patient without a previous history of abdominal trauma. Principal clinical findings were pain in left upper quadrant, nausea, regurgitation and precocious satiation. On investigation, ultrasonography and CT scan showed an expansive lesion in the spleen, compressing the stomach. Surgical procedure was splenectomy and a microscopical examination revealed a non- parasitic, non-neoplastic splenic cyst. Splenic cysts are usually benigns, but surgical remotion is necessary when they are symptomatic or exist risk of rupture. In this report is presented the classification of splenic cysts, clinical manifestations, diagnostics methods and discussed their surgical treatment.
