Pancreatitis associated with pleural-mediastinal pseudocyst, panniculitis and polyarthritis

Clinical characteristics, treatment, and outcome of pancreatitis, panniculitis, and polyarthritis syndrome: a case-based review

A 42-year-old Caucasian female presented with lower limb panniculitis and bilateral ankle arthritis in the absence of abdominal or other localizing symptoms. Abdominal imaging revealed subacute pancreatitis with pseudocyst formation. The clinical manifestations were compatible with pancreatitis, panniculitis, and polyarthritis syndrome (PPP syndrome), a very rare complication of pancreatic disease. The patient improved with conservative treatment for the pancreatic disease and systemic corticosteroids for the cutaneous and articular manifestations. We identified 59 patients with the PPP syndrome from the literature, the majority of patients being male (74.6%) with a median age of 49 (IQR 41-63.5) years. Acute pancreatitis is the most frequent underlying disorder (54.2%), but gastrointestinal symptoms are absent in 45.8% of patients. Pancreatic panniculitis has a predilection for the lower limbs, which are affected in 98.3% of cases. However, the cutaneous lesions may also involve the upper limbs and trunk. Arthritis is typically symmetric and polyarticular in nature, affecting both large and small joints. Of all patients who received treatment, 78.6% had a poor response. Death occurred in 27.1% of cases after a median duration of 8 (IQR 3.5-14) weeks.

Pancreatic panniculitis in a patient with pancreatic-type acinar cell carcinoma of the liver--case report and review of literature

Background

Pancreatic panniculitis is a rare condition, which has only been described in relation with pancreatic diseases up to now. It is characterized by necrotizing subcutaneous inflammation and is thought to be triggered by adipocyte necrosis due to systemic release of pancreatic enzymes with consecutive infiltration of neutrophils. We present the first case of a patient with pancreatic panniculitis caused by pancreatic-type primary acinar cell carcinoma (ACC) of the liver and without underlying pancreatic disease.

Case presentation

A 73-year old Caucasian female patient was referred to our department with painful cutaneous nodules persisting for eight weeks and with marked lipasemia (~15000 U/l; normal range <60 U/l). Four weeks prior, several liver lesions had been detected. Empiric treatment with steroids did not show any effect. A biopsy of the skin nodules revealed “pancreatic” panniculitis, while abdominal imaging with ultrasound, computed tomography and magnetic resonance imaging detected no abnormal pancreatic findings. Ultrasound-guided biopsy of the liver lesions showed infiltrates of an ACC. The patient died soon thereafter. Autopsy failed to reveal any other primary for the ACC, so that a pancreatic-type ACC of the liver was diagnosed by exclusion.

One hundred thirty cases of pancreatic panniculitis published within the last 20 years are reviewed. ACC of the pancreas is the most common underlying neoplastic condition. Patients with associated neoplasm are significantly older, take longer to be diagnosed and have higher lipase levels than patients with underlying pancreatitis.

Extrapancreatic pancreatic-type ACC is very rare, but shows the same biological features as ACC of the pancreas. It is believed to develop from metaplastic or ectopic pancreatic tissue. Up to now, no pancreatic panniculitis in extrapancreatic ACC has been described.

Conclusion

Pancreatic panniculitis should always be included in the differential diagnosis of lipolytic panniculitic lesions. It can be regarded as a facultative paraneoplastic phenomenon.

When suspected, a thorough work-up for identification of the underlying disease is mandatory and extrapancreatic lesions (e.g. liver) should also be considered. While administration of octreotide or steroids can sometimes alleviate symptoms, immediate treatment of the associated condition is the only effective management option.

Polyarthritis and pancreatic panniculitis associated with pancreatic carcinoma: review of the literature

Pancreatic disorders, such as chronic or acute pancreatitis, and carcinoma may be infrequently accompanied or preceded by panniculitis or polyarthritis. This triad is known in the literature as the pancreatitis, panniculitis, and polyarthritis syndrome. Although the pancreatic disease of pancreatitis, panniculitis, and polyarthritis syndrome usually includes pancreatitis, here we review the literature with report of 1 additional case of polyarthritis and panniculitis occurring in the presence of pancreatic carcinoma. Given that the diagnosis is often difficult when abdominal symptoms are absent, knowledge of the association between panniculitis and polyarthritis with pancreatic disease may lead to a prompt diagnosis and management. The histopathology of the skin lesions can be a valuable clue for focusing attention to a pancreatic disease.

Pancreatic panniculitis associated with acinar cell carcinoma of the pancreas: a case report

Pancreatic panniculitis is a rare type of disorder associated with pancreatic diseases. We describe here a case of 54-year-old man who was admitted to the Department of Dermatology with the diagnosis of erythema nodosum. The patient presented with a 9-month history of painful erythematous nodules on the extremities, joint pain and swelling, and weight loss. A highly elevated level of pancreatic lipase was found on the laboratory examinations. The biopsy specimens from the skin lesions showed subcutaneous fat necrosis. Abdominal computed tomography (CT) revealed a large mass with central necrosis in the body and tail of the pancreas. Distal pancreatectomy, splenectomy and partial transverse colectomy were successfully performed on day 17 of the hospitalization. The histopathologic findings supported the diagnosis of acinar cell carcinoma of the pancreas (ACCP). Postoperatively, the level of serum lipase returned to normal, and the skin lesions and joint manifestations gradually regressed. However, the swelling did not significantly resolve in the left knee. In view of the non-specific clinical presentation of this disease, clinicians should be alert and have a high index of suspicion for pancreatic panniculitis.

Metabolic panniculitis: alpha-1 antitrypsin deficiency panniculitis and pancreatic panniculitis

Panniculitis can be the initial presentation of both alpha-1 antitrypsin deficiency and pancreatic disease. They can both present with abscess-like draining nodules, but may present like other forms of panniculitis with erythematous nodules. It is important to consider these in the differential diagnosis of patients presenting with panniculitis. Alpha-1 antitrypsin deficiency is a relatively common disorder mainly affecting the lungs and liver. It frequently goes undiagnosed, yet critical interventions can be made to minimize disease progression. Panniculitis associated with alpha-1 antitrypsin deficiency can be difficult to treat. Pancreatic panniculitis occurs in less than 3% of patients with underlying pancreatic disease and is often associated with arthritis. Diagnosis and treatment of the underlying pancreatic disease is imperative.

Polyarthritis with chondronecrosis associated with osteonecrosis, panniculitis and pancreatitis

Arthritis associated with panniculitis complicating pancreatitis is well described in the literature, usually associated with osteonecrosis. Chondronecrosis has not been reported before in association with pancreatitis. We report a patient with chronic pancreatitis who presented with polyarthritis, panniculitis, osteonecrosis, but in addition had clear evidence of chondronecrosis. We suggest that direct extension of noxious materials from nearby subchondral osteonecrotic bone lesion could be the cause of the osteonecrosis and one of the pathological mechanisms leading to arthritis in patients with pancreatitis.

Pancreatic panniculitis caused by L-asparaginase induced acute pancreatitis in a child with acute lymphoblastic leukemia

Panniculitis caused by L-asparaginase induced acute pancreatitis is an unusual condition. We report a case of a 7-year-old Thai boy with underlying acute lymphoblastic leukemia who developed pancreatic panniculitis caused by L-asparaginase administration. During the second week of induction chemotherapy, the patient developed acute pancreatitis with septic shock. Two weeks later he developed multiple subcutaneous nodules on the abdominal wall. Skin excisional biopsy showed the typical histopathological features of pancreatic panniculitis. Acute pancreatitis improved after 3 weeks of conservative treatment. The skin lesions resolved spontaneously within 1 month.

Pancreatitis, panniculitis, and polyarthritis

BACKGROUND AND OBJECTIVE

Lobular panniculitis, together with polyarthritis and intraosseous fat necrosis, may occasionally complicate pancreatic disease. This triad is known in the literature as the pancreatitis, panniculitis, and polyarthritis (PPP syndrome). We describe a case of the PPP syndrome and review the available literature to summarize the clinical characteristics of patients with this condition.

METHODS

A patient with the PPP syndrome, with evidence of extensive intraosseous fat necrosis in the joints involved revealed by magnetic resonance imaging, is described and the relevant literature based on a PubMed search from 1970 to February 2008 is reviewed. The keywords used were pancreatitis or pancreatic disease, panniculitis, arthritis, and intraosseous fat necrosis.

RESULTS

Including our case, 25 well-documented patients with the PPP syndrome have been reported. Our patient had few abdominal symptoms despite high serum levels of pancreatic enzymes. In our review of the literature, almost 2/3 of patients had absent or mild abdominal symptoms, leading to misdiagnosis. The delay in diagnosis and specific treatment of the underlying pancreatitis worsens the prognosis of this condition, which has a mortality rate as high as 24%. In nearly 45% of the patients, the arthritis follows a chronic course with a poor response to nonsteroidal anti-inflammatory drugs and corticosteroids, and the rapid development of radiographic joint damage.

CONCLUSION

Certain forms of pancreatic disease can very occasionally cause arthritis and panniculitis. Although uncommon, physicians should be alert to the possible presence of this syndrome for 2 reasons: first, unrecognized pancreatic disease can be fatal if not treated promptly; second, to avoid inappropriate and risky therapy to improve joint symptoms.

Panniculitis, polyarthritis and osteomyelitis associated with pancreatic neoplasia in two dogs

A 12-year-old crossbred dog (case 1) and a 12-year-old Shetland sheepdog (case 2) were presented with a history of lameness and distal limb swelling. Physical examination revealed joint effusions and asymmetrical swellings of the extremities. In case 1, a diagnosis of arthritis and cellulitis was made on fine-needle aspiration biopsy of the synovium and subcutis. In case 2, bone biopsies and synovial aspirates diagnosed osteomyelitis and arthritis. A diagnosis of pancreatic disease was made on the findings of marked elevations of serum lipase concentrations and ultrasonographic identification of pancreatic masses in both cases. Both the cases were non-responsive to symptomatic management and were subsequently euthanased. Postmortem examination confirmed the diagnosis of panniculitis, arthritis and osteomyelitis in both cases. A pancreatic exocrine adenoma was identified in case 1 and a pancreatic adenocarcinoma with widespread metastases in case 2. To the authors' knowledge the association of panniculitis, polyarthritis and osteomyelitis with pancreatic disorders has not been reported previously in canine clinical cases.

Panniculitis. Part II. Mostly lobular panniculitis

The second part of our review of panniculitis summarizes the clinicopathologic features of the mostly lobular panniculitides. Erythema induratum of Bazin (nodular vasculitis) represents the most common variant of lobular panniculitis with vasculitis, although controversy persists about the nature of the involved vessels. Mostly lobular panniculitides without vasculitis comprise a series of disparate disorders. These include sclerosing panniculitis that results from chronic venous insufficiency of the lower extremities; panniculitis with calcification of the vessel walls such as calciphylaxis and oxalosis; and inflammatory diseases with crystals within the adipocytes such as sclerema neonatorum, subcutaneous fat necrosis of the newborn, and poststeroid panniculitis. Connective tissue diseases, such as systemic lupus erythematosus and dermatomyositis, pancreatic diseases, and alpha(1)-antitrypsin deficiency may also show a mostly lobular panniculitis with characteristic histopathologic features. Lobular panniculitis may also be an expression of infections, trauma, or factitial causes involving the subcutaneous fat. Lipoatrophy refers to a loss of subcutaneous fat due to a previous inflammatory process involving the subcutis, and it may be the late-stage lesion of several types of panniculitis. In contrast, lipodystrophy means an absence of subcutaneous fat with no evidence of inflammation and often the process is associated with endocrinologic, metabolic, or autoimmune diseases. Finally, cytophagic histiocytic panniculitis is the term that has been used to describe two different processes: one is inflammatory, a lobular panniculitis, and the other one is neoplastic, a subcutaneous T-cell lymphoma. The only common feature of these two different processes is the presence of cytophagocytosis in the lesions. (J Am Acad Dermatol 2001;45:325-61.)

LEARNING OBJECTIVE

At the completion of this learning activity, participants should be familiar with the pathogenesis, clinical manifestations, histopathologic findings, and treatment options for the most frequent variants of the lobular panniculitides.
