Autoimmune pancreatitis (AIP) can be chronic or recurrent, but frequently completely reversible after steroid treatment. A cystic lesion in AIP is a rare finding, and it can mimic a pancreatic cystic neoplasm. Difficulties in an exact diagnosis interfere with treatment, and surgery cannot be avoided in some cases. We report the history of a 63-year-old male presenting with jaundice and pruritus. AIP was confirmed by imaging and elevated IgG4 blood levels, and the patient completely recovered after corticosteroid therapy. One year later, he presented with a recurrent episode of AIP with elevated IgG4 levels, accompanied by the appearance of multiple intrapancreatic cystic lesions. All but 1 of these cysts disappeared after steroid treatment, but the remaining cyst in the pancreatic head was even somewhat larger 1 year later. Pancreatoduodenectomy was finally performed. Histology showed the wall of the cystic lesion to be fibrotic; the surrounding pancreatic tissue presented fibrosis, atrophy and lymphoplasmacytic infiltration by IgG4-positive cells, without malignant elements. Our case illustrates the rare possibility that cystic lesions can be part of AIP. These pseudocysts appear in the pancreatic segments involved in the autoimmune disease and can be a consequence of the local inflammation or related to ductal strictures. Steroid treatment should be initiated, after which these cysts can completely disappear with recovery from AIP. Surgical intervention may be necessary in some exceptional cases.

A 79-year-old man was admitted with asymptomatic elevation of liver enzymes and tumor markers. Abdominal contrast-enhanced computed tomography demonstrated swelling of the pancreatic head, and additional blood test showed raised IgG4 levels. Histological examination by endoscopic ultrasonography (EUS)-guided fine needle aspiration for pancreatic head mass revealed storiform fibrosis and IgG4-positive plasma cell infiltration. We diagnosed this case as type 1 autoimmune pancreatitis (AIP). In addition, there was a cystic lesion in the pancreatic body apart from the pancreatic head mass. A mural nodule in the multilocular cyst was detected by EUS, and there was positive uptake of fluorodeoxyglucose in positron emission tomography/magnetic resonance imaging. The preoperative diagnosis of this cystic lesion was intraductal papillary mucinous carcinoma, and distal pancreatomy was performed. Histopathological findings showed various sizes of retention cysts caused by IgG4-positive plasma cell infiltration around the pancreatic branch ducts. The mural nodule was a fibrotic mass with diffuse infiltration of IgG4-positive cells. This cystic lesion mimicking malignant cystic neoplasm occurred in relation to AIP. This case provided important information helping to understand the mechanism of formation of mural nodules in multilocular cysts in patients with type 1 AIP.

Introduction: Pancreatic cysts are common (2.5%). Cystic neoplasms represent 10% of cystic lesions and 1% of pancreatic tumors. However, it is difficult to differentiate benign cyst from malignant cystic lesions preoperatively.Objective: To study the cases of pancreatic cystic lesion who underwent various forms of pancreatic resection.Materials and Methods: Nine cases of pancreatic cystic lesion who presented to Kathmandu Medical College Teaching Hospital, Surgical Unit 3 within December 2014- November 2015 were evaluated. Four pancreatic cysts who underwent resection are discussed whereas not managed with resection are excluded.Results: There were 4 cases of pancreatic cyst who underwent pancreatic resection. First case underwent pancreaticoduodenectomy for pancreatic mucinous cystadenoma. However histopathological examination revealed a serous cystadenoma. In second case, pancreatic neck lesion suspected to be mucinous cystadenoma or pseudocyst in MRCP, with negative malignant cells in EUS guided FNAC underwent Central pancreatectomy and was found to be serous cystadenoma. The third case with suspected pseudocyst underwent Pancreaticoduodenectomy after a 3X2 cm2 cystic mass was felt at the posteroinferior side of pancreatic head and malignancy was suspected intraoperatively . HPE report was mucinous cystadenoma. The fourth case with pancreatic pseudocyst at tail with duct calculi and chronic pancreatitis underwent distal pancreatectomy with splenectomy with Frey’s procedure.Conclusion: Management of pancreatic cystic lesion is challenging. Though radiological imaging has limited role in accurate diagnosis, endoscopic ultrasound may be of some benefit.

Acinar cystic transformation (ACT), also known as “acinar cell cystadenoma,” is a rare and newly recognized benign pancreatic cystic neoplasm. However, its true malignant potential remains unknown. Here, we report a case of ACT with 15-year follow-up. A 10-year-old female initially presented with abdominal pain and was found to have a cystic lesion in the region of pancreatic head on computed tomography scan. She underwent an exploratory laparotomy, and the intraoperative biopsy of the cyst wall showed a true pancreatic cyst without malignancy. Her symptoms subsequently resolved, and she was placed under close ultrasound surveillance. For the next fifteen years, the patient was asymptomatic without any complications and had a successful pregnancy. Surveillance showed the tumor grew in size from 4.2 cm to 6.2 cm in diameter. In the latest five months, she noted occasional abdominal pain. A pylorus-preserving pancreaticoduodenectomy was performed. The resected cystic lesion was multilocular and lined by a single layer of bland epithelium ranging from nondescript flat/cuboidal epithelium to apparent acinar cells which were strongly positive for trypsin, so the final diagnosis was confirmed to be ACT. The prior biopsy was retrospectively reviewed to reveal similar epithelial lining. To the best of our knowledge, this is the longest period of follow-up for ACT to date. Our findings suggest that ACT is a slow-growing neoplasm without malignant transformation after fifteen years. Therefore, we recommend biopsy for histologic diagnosis followed by close ultrasound surveillance without surgical intervention in asymptomatic or young ACT patients.

A 75-year-old man who was diagnosed as having mucin-producing pancreatic cystic lesion ofthe main pancreatic duct by duodenoscopic examination was reported. Because of the low malignant potential of such lesions, duodenum-preserving resection of the head of the pancreas was performed, and the intra-operative histological examination showed no malig-nancy of the resected pancreatic head and no other surgical procedures, such as lymph-adenectomy nor pancreato-duodenectomy were necessary. The significance of this case report lies in that a less invasive operation should be selected at first to diagnose whether the lesion is malignant or not, and als0 that the selected operation itself must be sufficient to resect an adequate part of the pancreatic tissue involving the cystic lesion, ifnot malignant. Here, we report the process to select the procedure and the surgical technique.

A 60-year-old woman presented with a swelling in right paraumbilical region of one-year duration. Examination revealed a painless cystic swelling 15 × 10 cm with cough impulse. Ultrasound and CECT abdomen showed a subcutaneous cystic swelling with intramuscular extension. No other intraabdominal cystic lesions were found. Surgical exploration showed a cystic lesion adherent to peritoneum without any intraperitoneal extension. Cyst was carefully excised without any spillage. Gross specimen on opening showed multiple daughter cysts consistent with hydatid cyst, confirming the diagnosis of solitary abdominal wall hydatid cyst.

Összefoglaló. Csecsemőkorban a here cysticus elváltozásai ritka entitásnak számítanak. Az angol nyelvű szakirodalom kevés hasonló esetről számol be, a 2000-es évek elejéig publikált esetek harmadában orchiectomia történt. A hisztológia a leggyakrabban teratomát, a legritkábban egyszerű cystát igazol. Mindkét elváltozás jóindulatú, egyéves kor alatt a leggyakoribb. Közleményünkkel arra szeretnénk felhívni a figyelmet, hogy ezen esetek kezelése során törekedni kell a here megtartására. A Pécsi Tudományegyetem Klinikai Központ Gyermekgyógyászati Klinikájának Manuális Tanszékén és a Heim Pál Országos Gyermekgyógyászati Intézet I. Gyermek Ssebészeti és Traumatológiai Osztályán 2015 és 2018 között 4 csecsemőben észleltük a here cysticus elváltozását. A betegek kórtörténeti adatainak részletes retrospektív elemzését és a szakirodalom áttekintését végeztük. Mind a 4 alkalommal a csecsemő féléves kora előtt észleltek egyoldali, panaszokat nem okozó herezacskófél-megnagyobbodást. Az ultrahangvizsgálat 3 esetben szoliter cysticus képletet talált. 1 esetben szeptált, sűrű folyadékkal telt cysticus képletet véleményezett, számottevő hereállomány nem mutatkozott. Ennél a betegnél mágnesesrezonancia-vizsgálat is készült, mely teratoma lehetőségét vetette fel. A feltárás során mindegyik csecsemőben cysticus képletet találtunk. 3 betegnél hereszövet-megtartó műtétet (enucleatiót) végeztünk. 1 esetben az érdemben megtartható hereszövet hiánya, valamint teratoma gyanúja miatt orchiectomia történt. A kórszövettan két esetben egyszerű cystát, két esetben praepubertalis teratomát igazolt, melyek jóindulatú elváltozások. A here cysticus elváltozásai csecsemőkorban döntő többségben benignusak. Az egyszerű cysta és a praepubertalis teratoma egyaránt jóindulatú elváltozás, malignus transzformációra nem hajlamosak. A képalkotó eljárások közül az ultrahangvizsgálat elegendő lehet a kezelési terv felállításához. Mindig törekedni kell a here megtartására, a lehető legtöbb hereszövet megkímélésére. Kórszövettani vizsgálat nélkül a here eltávolítása ebben az életkorban nem javasolt. Orv Hetil. 2020; 161(48): 2043–2048. Summary. Cystic lesions of the testis are rare in infancy. Few similar case-series were published in the English literature. Orchiectomy was reported in one-third of the cases until the early 2000s. Histology mostly confirms teratomas, rarely simple cysts. Both are benign and most common under the age of one year. Our aim is to draw attention to the importance of testicular sparing surgery (enucleatio), whenever possible. At the Medical Centre of the Department of Pediatrics of the Division of Paediatric Surgery, Pécs and at the Department of Pediatric Surgery and Traumatology of the Heim Pal Children’s Hospital, Budapest, four cystic testicular lesions were treated in infancy between 2015 and 2018. We performed retrospective analysis and reviewed relevant literature. Our patients were under six months and an unilateral, painless scrotal enlargement appeared. Ultrasound described cystic lesion in the testis in three cases. In one case a septated, echogenic, liquid-filled cystic lesion was detected, with no significant amount of testicular tissue. Magnetic resonance imaging scan of this patient predicted the diagnosis of teratoma. During the surgeries, cystic lesions were found in all cases. Enucleatio was performed in three patients. Orchiectomy was carried out once due to the suspicion of teratoma and the lack of salvageable testicular tissue. Histopathology confirmed simple cysts in two babies and prepubertal teratomas in the others. Testicular cystic lesions are predominantly benign in infancy. Simple cysts and prepubertal teratomas are benign, not prone to malignant transformation. Ultrasound is reliable for preoperative planning. Testicular tissue sparing surgery must be considered and without histopathology orchiectomy should not be performed. Orv Hetil. 2020; 161(48): 2043–2048.

Abstract Background Endometriosis of the uterine body can be manifested as diffuse solid lesions or cystic lesions. The former is common, while the latter is rare, especially for cystic adenomyosis larger than 5 cm. Case presentation A 30-year-old woman was admitted for severe and worsening dysmenorrhea. Ultrasound examination revealed a rare well-circumscribed cystic lesion about 5.5 × 4 × 5.0 cm. CA-125 level was slightly elevated. She accepted laparoscopic surgery and the adenomyotic tissues were excised. The histopathology of the specimen demonstrated the endometrial glands in the walls of cysts and an area of extensive hemorrhage can be seen in the inner wall of cyst. The patient made a good recovery after surgery and her symptoms complete resoluted. Conclusions This is a rare case of a cystic adenomyotic lesion that was treated by laparoscopic surgery.
