Generalized lymphedema in a sirolimus-treated renal transplant patient.

Generalized lymphedema is an extremely rare effect of sirolimus therapy in renal transplant recipients. We describe the development of this complication in a 56-yr-old woman, who was given an experimental protocol with cyclosporine, sirolimus, steroids, and basiliximab. Following the protocol, after one month, the patient was randomized to the "sirolimus only" group, while cyclosporine was completely suspended and the oral steroids were continued. Three months later, the patient was admitted for severe lymphedema of the lower limbs, with significant weight increase, massive ascites and dyspnea, but excellent renal function. A chest radiography and an ultrasound study of the heart showed a moderate pleural and pericardial effusion. An abdominal ultrasound scan showed two small lymphoceles next to the transplanted kidney, confirmed with a CT scan. After sirolimus discontinuation the generalized lymphedema started to improve and three months later all the symptoms had disappeared.

Papillary thyroid microcarcinoma (Black Ink).

We report a case of a 58-year-old Caucasian woman affected by papillary thyroid microcarcinoma (PTMC) of the left-lobe of the gland with very small size (Ø 0.3 cm). The characteristics with the Diagnostic Imaging using Ultrasonography, ADF (Advanced Dynamic Flow), and fine-needle-aspiration cytology (FNAC) are discussed, comprising a very small micro-focus of radial shape, with markedly hypoechoic echostructure, irregular margins, supplemented by peripheral vessel formation. It acquires an image which appears similar to a brisk visualization of a dark ink stain in the normal thyroid weave. We call such a pattern "Black Ink" with ultrasonographic image and believe consistent with the infiltrating variant of papillary thyroid microcarcinoma if associated with malignant cytology after FNA.

[Cystadenoma of the pancreas: 4 cases in our clinical experience]. / Cistoadenomi del pancreas: 4 casi nella nostra esperienza clinica.

Cystic neoplasms account for about 10% of all cystic lesions of the pancreas and less than 1% of all exocrine pancreatic neoplasms. The authors report 4 cases of pancreatic cystadenoma (3 women and 1 man; mean age 59 years; range: 41-72), 2 serous and 2 mucinous, treated over the period from 1999 to 2002. The main symptoms were hypochondrial pain in two patients and diffuse abdominal pain in one while the fourth patient was asymptomatic. The patients were studied clinically by CT, echotomography and angiography. In three cases the tumours were located in the pancreatic body-tail, and in one case in the head. Serum amylase, lipase and tumour markers were all in the normal range. Only in one case was there an accurate preoperative diagnosis of tumour; in the other cases, a histological diagnosis was possible after surgical resection. Surgical treatment depended on tumour localisation: duodeno-cephalopancreatectomy for tumours in the head and distal pancreatectomy with splenectomy for tumours located in the body-tail, Lymphadenectomy at levels I and II was performed in all cases. There was no postoperative mortality and only one female patient developed postoperative acute pancreatitis. During the follow-up CT scans showed no recurrence of the pancreatic tumours. In agreement with the international literature, we hold that all cystic tumours of the pancreas should be treated by surgical therapy, above all because of the major differential diagnosis problems they continue to present. Conservative treatment is justified only for well documented asymptomatic serous cystadenomas.

Massive upper gastrointestinal bleeding from a pancreatic pseudocyst rupture: a case report.

INTRODUCTION: Bleeding from pancreatic pseudocyst's rupture into adjacent organs is a rare, but potentially fatal, complication of chronic pancreatitis requiring quick management. Timing of the rupture is unpredictable; early diagnosis and correct management is essential in preventing the bleeding. CASE PRESENTATION: We describe the case of a 53 years old male patient successfully treated with emergency surgery for massive hematemesis due to a rupture of a bleeding pseudocyst into the stomach. Patient underwent emergency laparotomy and suture of the bleeding vessel. At 5 years follow-up patient is in healthy condition. CONCLUSION: This case shows to surgeons that pancreatic pseudocyst cannot be managed strictly with one rule and prompt surgical treatment is mandatory in case of haemodinamic instability.
