Gel fractionation of portal, arterial and peripheral plasma glucagon levels was performed before and after the successful removal of a
glucagonoma
. A 47 year old woman had symptoms of dermatitis, weight loss,
anemia
and diabetes mellitus over a 16 year period. Removal of the alpha-cell tumor corrected all of her symptoms. Gel filtration of portal, arterial and peripheral blood showed two peaks of glucagon radioimmunoassay activity, a higher molecular weight glucagon with a molecular weight of 9,000 and a 3,500 dalton glucagon. Five minutes after tumor removal, the higher molecular weight glucagon had disappeared completely from the arterial and peripheral blood but not from the portal vein.

Glucagon-producing tumors of the pancreas are among the rarest forms of islet cell tumors. Two patients are described in whom the characteristic dermatitis, glucose intolerance, weight loss, and
anemia
of the
glucagonoma
syndrome were due to a metastasizing islet cell carcinoma. In both, removal of the primary tumor with a distal pancreatectomy brought marked relief of all clinical symptoms for 1- and 2-year periods. Because streptozocin, the usual chemotherapeutic agent for these tumors, is quite toxic and frequently unsuccessful dimethyltriazenoimidazole carboximide (DTIC) was used for recurrence after operation. The first patient began taking DTIC when his rash reappeared and his immunoreactive glucagon (IRG) level rose to 6,000 pg/ml (normal, less than 200 pg/ml). Within 3 months, his rash was gone, and IRG level was 75 pg/ml. The second patient developed a neoplastic gastrocolic fistula and was extremely emaciated. With DTIC, the fistula healed, and he gained weight and returned to work. His IRG level has decreased from 2,975 to 200 pg/ml. No side-effects were noted during chemotherapy. Temporary palliation of malignant glucagon-producing neoplasms can be achieved by cytoreductive surgery. When the life-threatening symptoms of this syndrome recur, DTIC chemotherapy seems indicated because of its safety and effectiveness.

A 60-year-old patient developed signs and symptoms of
glucagonoma
syndrome (dermatitis, weight loss,
anemia
and hypoaminoacidemia). However, diabetes mellitus was absent.
Glucagonoma
was suspected because of markedly elevated plasma glucagon levels and the tumor was subsequently removed by surgery. Acidethanol extraction of the tumor and immunohistochemistry provided evidence of the presence of all four islet hormones, particularly that of glucagon and pancreatic polypeptide and to a lesser extent of somatostatin and insulin. Immunohistochemistry of the tumor (but not plasma) also showed the presence of alpha-HCG. Plasma glucagon immunoreactivity consisted to a large extent (approx. 90%) of a high molecular form of glucagon, probably proglucagon. In spite of the presence of alpha-HCG - which is assumed to be a marker of malignancy - the patient has been free of recurrence for the 2 1/2 years since surgery. The increasing number of cases reported during the past few years demonstrates that the syndrome is more common than previously suspected. Glucagon secretion and its typical clinical picture may be a valuable marker of a multihormonal pancreatic tumor. In a case of suspected
glucagonoma
, diagnosis can be established simply by obtaining a plasma glucagon level measurement.

The features of 41 proven or suspected cases of
pancreatic glucagonoma
and one possible case of renal
glucagonoma
have been reviewed.
Glucagonoma
is one form of islet cell neoplasm and involves pancreatic alpha cells. It may occur more frequently in women and is more likely to be malignant than insulinoma. Patients may present with glucose intolerance, an erythematous, eczematous dermatitis, glossitis, stomatitis, vaginitis and unexplained weight loss.
Anemia
, hypoproteinemia, hypoaminoacidemia and hypolipidemia may also be present. Malignant glucagonoma metastasizes frequently to liver. An evaluation for possible
glucagonoma
may be considered in a patient with the characteristic eczematous dermatitis, glossitis or stomatitis and glucose intolerance, an unusual or atypical history of diabetes mellitus, or hepatomegaly with other characteristics of
glucagonoma
. Initial evaluation may include measurement of fasting plasma glucagon concentration, and an oral glucose tolerance test with measurements of plasma glucose and glucagon levels. Extreme fasting hyperglucagonemia, and a paradoxical rise in plasma glucagon concentrations after glucose ingestion should strongly suggest the presence of
glucagonoma
. Radiographic demonstration of
pancreatic glucagonoma
is best carried out by celiac arteriography. Surgical excision of the tumor is the treatment of choice. Nonresectable lesions may respond to chemotherapy with streptozotocin. Treatment for the various dermatologic or metabolic complications of
glucagonoma
which include glucose intolerance, hypoproteinemia, hypocholesterolemia and
anemia
may not be satisfactory. Glucose intolerance is usually mild and may be adequately treated with dietary or insulin therapy. Rarely,
glucagonoma
with massive destruction of the pancreas or other factors may induce severe glucose intolerance. In contrast, the
anemia
, skin rash, and hypoproteinemia do not respond to conservative therapies tested thus far.
Glucagonoma
is a model for studying the importance of glucagon in causing the hyperglycemia of diabetes mellitus. Study of patients with
glucagonoma
does suggest that glucagon has some role in the etiology of hyperglycemia in diabetic states; however, as in studies on diabetes, investigations on
glucagonoma
do not demonstrate that glucagon has a primary role in producing severe glucose intolerance.

Glucagonoma
is a rare pancreatic tumor, necrolytic migratory erythema is its distinctive feature and it is often associated with diabetes mellitus, weight loss,
anemia
, hypoaminoacidemia, glossitis and stomatitis. We reported a case of
glucagonoma
misdiagnosed as "eczema" and "benign hepatic anginoma" for 3 years. His blood glucagon level was 1,758 ng/L. The results of abdominal B-mode ultrasonography and CT scan were negative, but selected arteriogram showed a tumor mass between the pancreatic body and tail. Before operation, treatment with octreotide and supply of amino acids were given with improvement of the skin lesion. After resection of the tumor from pancreas, necrolytic migratory erythema disapeared, but his blood level of glucagon and amino acids did not improve. It is suggested that any diabetic patient with chronic skin damage should be checked for blood glucagon level. In suspected cases, selected arteriogram will be helpful for location of the tumor. Vigorous resection of the pancreatic tumor should be done as soon as possible, even though there is already metastases.

A 67-year-old man with diabetes, weight loss and
anaemia
initially presented with a widespread scaling erythematous rash; a skin biopsy demonstrated marked suprabasal acantholysis. A subsequent biopsy showed localized upper epidermal necrolysis and the diagnosis of
glucagonoma
syndrome was later confirmed.
Glucagonoma syndrome
should be considered in patients with diabetes, weight loss and
anaemia
who present with a scaling rash, the histology of which shows suprabasal acantholysis. The extent of any upper epidermal necrolysis may be be very limited.

Glucagonoma
is a neuroendocrine tumor of pancreatic alpha cells manifested by necrolytic migratory erythema, hyperglucagonemia, glucose intolerance, weight loss,
anemia
and hypopaminoacidemia. We report a case of
glucagonoma
in a 38 years-old patient diagnosed by the presence of a pancreatic tumor, liver metastasis, weight loss, glucose intolerance, necrolytic migratory erythema, hyperglucagonemia (1400 pg/ml; normal < 200 pg/ml) and histologic demonstration of glucagon and neurospecific enolase by immunocytochemical reaction. Actual therapeutic of
glucagonoma
includes surgery, chemotherapy, somatostatin or octreotide for control of the symptoms, and more recently alpha-interferon was suggested.

Glucagonoma
is a relatively rare pancreatic islet cell tumor. Historically, these tumors present a typical constellation of symptoms including diabetes, weight loss,
anemia
, necrolytic migratory erythematous rash, and propensity for thrombosis. This clinical presentation is described as the
glucagonoma
syndrome. The syndrome can be confirmed with the use of serum measurements of glucagon levels and immunohistochemical assay of the tumor. Variations from the classic syndrome have been described, and serum measurements of glucagon in patients with suspected islet cell tumors can identify subsets of patients with
glucagonoma
who do not exhibit the classic syndrome. In our case, the unusual presentation of
glucagonoma
included the previously unreported component of an intravascular venous extension of tumor.

Of the rare pancreatic endocrinomas, glu-cagonomas, either with or without diabetico-dermatogenic syndrome (DDS), are probably third in frequency after insulinomas and gastrinomas. This study was carried out to evaluate the present status of
glucagonoma
/DDS in a statistically reliable number of cases and to provide precise information to investigators actively working in this particular field of research. A total of 407 cases of
glucagonoma
were collected from the international literature and evaluated according to characteristic clinicopathologic features. Findings were: (1) The incidence of DDS was 57.2% (233/407). (2) The tail of the pancreas was predominantly involved, in 53.7% (213/397). (3) One-third of the tumors (80 of 276 for whom size was recorded; 29.0%) measured 20 mm or less. (4) Metastases occurred in 51.4% (209/407) and malignant tumors in 60.7% (247/407). (5) Multiplicity occurred in 11.8% (48/407), and associated multiple endocrine neoplasia type 1 in 13. 0% (53/407). (6) In the patients with DDS, the rates of hyperglucagonemia, necrolytic migratory erythema, diabetes mellitus, loss of weight, hypo-aminoacidemia, or
anemia
, as representative constituents of DDS, were all higher than rates in the overall series (P < 0.01). (7) The 10-year survival rate in the 233 patients with DDS was 51.6% in those with metastases and 64.3% in those without metastases (P < 0.001).

Glucagonoma
is an endocrine tumor of almost exclusively pancreatic origin which is rarely associated with a clinical syndrome mainly characterized by migratory necrolytic erythema, hyperglycemia, weight loss, hypoaminoacidemia and
anemia
. Ten to 30% of the patients may present thromboembolic phenomenon, deep vein thrombosis and pulmonary embolism which often lead to the death of the patient. We report the case of a patient diagnosed with
pancreatic glucagonoma
the presentation of which consisted in episodes of repeated deep vein thrombosis without associated migratory necrolytic erythema.
