aDiabetic Foot Center, Department of Endocrinology and Metabolism bDepartment of Pathology cDepartment of Pancreatic Surgery dDepartment of Radiology, West China Hospital, Sichuan University, Chengdu, Sichuan, People's Republic of China.

Rationale: Glucagonoma and pancreatic serous oligocystic adenoma (SOA) are rare neuroendocrine and exocrine tumors of the pancreas, respectively. The coexistence of glucagonoma syndrome (GS) and SOA is a rare clinical condition and has not yet been reported. Additionally, necrolytic migratory erythema (NME), a hallmark clinical sign of GS, is often misdiagnosed as other skin lesions by clinicians due to their lack of related knowledge, which delays diagnosis of GS and thus exacerbates the prognosis.

Paediatrician for Inborn Errors of Metabolism, University of Groningen, University Medical Centre Groningen, Groningen, Netherlands.

In recent years the number of disorders known to affect amino acid synthesis has grown rapidly. Nor is it just the number of disorders that has increased: the associated clinical phenotypes have also expanded spectacularly, primarily due to the advances of next generation sequencing diagnostics. In contrast to the "classical" inborn errors of metabolism in catabolic pathways, in which elevated levels of metabolites are easily detected in body fluids, synthesis defects present with low values of metabolites or, confusingly, even completely normal levels of amino acids.

Ronald O. Perelman Department of Dermatology, New York University School of Medicine, New York, NY, USA.

New all-oral direct-acting antivirals (DAA) have changed the hepatitis C virus (HCV) treatment landscape. Given that dermatologists frequently encounter HCV-infected patients, knowledge of the current treatment options and their utility in treating HCV-associated dermatologic disorders is important. In addition to highlighting the new treatment options, we review four classically HCV-associated dermatologic disorders - mixed cryoglobulinaemia (MC), lichen planus (LP), porphyria cutanea tarda (PCT) and necrolytic acral erythema (NAE) - and examine the role for all-oral direct-acting antiviral (DAA) regimens in their treatment.

Glucagon and Amino Acids Are Linked in a Mutual Feedback Cycle: The Liver-α-Cell Axis.

Diabetes 2017 02;66(2):235-240

Novo Nordisk Foundation Center for Basic Metabolic Research, Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark.

Glucagon is usually viewed as an important counterregulatory hormone in glucose metabolism, with actions opposing those of insulin. Evidence exists that shows glucagon is important for minute-to-minute regulation of postprandial hepatic glucose production, although conditions of glucagon excess or deficiency do not cause changes compatible with this view. In patients with glucagon-producing tumors (glucagonomas), the most conspicuous signs are skin lesions (necrolytic migratory erythema), while in subjects with inactivating mutations of the glucagon receptor, pancreatic swelling may be the first sign; neither condition is necessarily associated with disturbed glucose metabolism.

Viruses are considered intracellular obligates with a nucleic acid RNA or DNA. They have the ability to encode proteins involved in viral replication and production of the protective coat within the host cells but require host cell ribosomes and mitochondria for translation. The members of the families Herpesviridae, Poxviridae, Papovaviridae, and Picornaviridae are the most commonly known agents for cutaneous viral diseases, but other virus families, such as Adenoviridae, Togaviridae, Parvoviridae, Paramyxoviridae, Flaviviridae, and Hepadnaviridae, can also infect the skin.

Glucagonoma syndrome is defined by the presence of an alpha-cell secreting tumour of the pancreas, elevated levels of glucagon, and a characteristic rash called necrolytic migratory erythema (NME). NME is usually a specific and often initial finding of glucagonoma syndrome, but it may occur in other settings unassociated with an alpha-cell pancreatic tumour (pseudoglucagonoma syndrome). Glucagonoma syndrome must be distinguished from pseudoglucagonoma syndrome. Read More

Pancreatic islet α-cell tumours that overexpress proglucagon are typically associated with the glucagonoma syndrome, a rare disease entity characterised by necrolytic migratory erythema, impaired glucose tolerance, thromboembolic complications and psychiatric disturbances. Paraneoplastic phenomena associated with enteric overexpression of proglucagon-derived peptides are less well recognized and include gastrointestinal dysfunction and hyperinsulinaemic hypoglycaemia. The diverse clinical manifestations associated with glucagon-expressing tumours can be explained, in part, by the repertoire of tumorally secreted peptides liberated through differential post-translational processing of tumour-derived proglucagon.

Simone Garcovich, Rodolfo Capizzi, Department of Dermatology, Policlinico A. Gemelli, Catholic University of Sacred Heart, 00168 Rome, Italy.

The association of chronic hepatitis C virus (HCV) infection with a wide spectrum of cutaneous manifestations has been widely reported in the literature, with varying strength of epidemiological association. Skin diseases which are certainly related with chronic HCV infection due to a strong epidemiological and pathogenetic association are mixed cryoglobulinemia, lichen planus and porphyria cutanea tarda. Chronic pruritus and necrolytic acral erythema are conditions that may share a possible association with HCV infection, while several immune-mediated inflammatory skin conditions, such as psoriasis, chronic urticaria and vitiligo, have been only anecdotally reported in the setting of chronic HCV infection.
