Pancreatic panniculitis is a rare skin complication in which subcutaneous fat necrosis occurs in association with pancreatic disorders, most commonly acute or chronic pancreatitis. Erythematous subcutaneous nodules develop on the legs and spontaneously ulcerate or exude an oily substance. A 32-year-old Korean female patient presented with a 2-week-history of tender nodules with erythematous crusts on her left shin. She had a history of alcoholic liver cirrhosis and, 5 weeks earlier, had been diagnosed with acute pancreatitis. The histopathologic findings from a skin biopsy were consistent with lobular panniculitis, without signs of vasculitis, and diffuse fat necrosis. Basophilic calcium deposits were present in the dermis and subcutaneous fat. These findings were suggestive of pancreatic panniculitis. The skin lesion had a chronic course corresponding to repeated exacerbations of the patient’s pancreatitis. Thus, in the differential diagnosis of subcutaneous nodules, clinicians should consider pancreatic panniculitis as a cutaneous manifestation of pancreatic disease.
This study aimed to provide an actualized classification system for acute pancreatitis (AP) by applying new principle and investigated the benefits of new classification.
Medical records and computed tomography (CT) images of 235 consecutive patients with AP admitted to the Ewha Womans University Mokdong Hospital between 2005 and 2010 were reviewed. The patients of severe pancreatitis who has necrosis were only 68 cases, these are too small for comparing to mild form. So we analyzed mild form of pancreatitis preferentially into two groups; group A, without morbidity and without organ failure (145 patients, mild acute pancreatitis, MAP); group B, with morbidity and without organ failure (22 patients, aggressive mild acute pancreatitis, AMAP). Clinical characteristics, laboratory findings, duration of hospitalization, need for the intensive care unit (ICU), organ failure, needs of intervention, another severity indexes and death were evaluated.
AMAP (group B) was higher proportion of need for the ICU care and of organ failure than MAP after age-adjusting (P<0.01). Also AMAP had higher incidence of associated malignancy, pseudocysts, and increasing fasting sugar level.
The AMAP is a different type of MAP. We need new category of different grade of mild form pancreatitis, because AMAP showed different clinical course. New classification of mild acute pancreatitis is relatively effective, and has clinically significant value.
Hyperlipidemia can be a cause of acute pancreatitis. For example, dyslipidemia classified Fredrickson/WHO classification type I, V can induce acute pancreatitis spontaneously. Secondary hyperlipidemia (DM, alcohol, estrogen, etc.) also can induce acute pancreatitis. High serum amylase level and triglyceride level are hall markers of diagnosis. But lactescent serum interferes with accurate laboratory analysis of amylase. Serum amylase was normal or low in 50% of cases. Clinical course and treatment are similar with other causes of acute pancreatitis. Lipoprotein electrophoresis helps classify dyslipidemia by Fredrickson/WHO classification. In some cases, to prevent hyperlipidemic pancreatitis, serum triglyceride should be lower than 500 mg/dl. We report two cases of acute pancreatitis caused by dyslipidemia.
