Mastocytosis is a clonal proliferation of mast cells that accumulates in one or more organs [1]. This disorder is heterogenous, ranging from skin lesion that may spontaneously regress to multiple organ lesions that show a highly aggressive course, and a recent World Health Organization Classification divides it into 7 subtypes: cutaneous mastocytosis, indolent systemic mastocytosis, systemic ma...

Eosinophilic gastroenteritis (EG) is an uncommon disorder, characterised by cramping abdominal pain, diarrhoea and vomiting and histologically by eosinophilic infiltration of bowel wall. We present a patient who developed EG during the course of a systemic, necrotising vasculitis, who became critically ill after failure of treatment with corticosteroids and cytotoxic drugs and responded only to...

Eosinophilic gastroenteritis is a condition characterised by eosinophilic infiltration of the gastrointestinal tract. Biliary obstruction is an unusual presentation. A case where the initial investigations were consistent with carcinoma of the head of pancreas but the resection specimen showed no malignancy is presented. The diagnosis was suspected from a review of the patient's past history an...

The hypereosinophilic syndrome is a severe disease affecting multiple organ systems as the heart, skin, liver, spleen, urinary, gastrointestinal, nervous, and hematopoietic systems. The most important findings are eosinophilic infiltration and peripheral eosinophilic leukocytosis. Here, we report liver involvement and abdominal computed tomography (CT) and ultrasonography (US) characteristics o...

We encountered an unusual and rare case of 59-year-old woman with Churg-Strauss syndrome (CSS) showing myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA)-related acute renal insufficiency accompanied by eosinophilic tubulointerstitial nephritis. To date, reports in English of CSS presenting with rapidly progressive/acute renal insufficiency and biopsy-proven renal lesions have been...

Eosinophilic myenteric ganglionitis is a disorder characterized by infiltration of the Auerbach myenteric plexus by eosinophils. As a cause of chronic intestinal pseudo-obstruction (CIPO), eosinophilic myenteric ganglionitis has been rarely reported and the majority of the reported cases in the literature were children. We experienced a case of eosinophilic myenteric ganglionitis associated wit...

Eosinophilic gastroenteritis (EGE) is a rare disease characterized by focal or diffuse eosinophilic infiltration of the gastrointestinal tract, especially the stomach and duodenum. EGE has vague, nonspecific symptoms, including nausea, vomiting, abdominal pain, diarrhea, weight loss, ascites, and malabsorption. Here, we report a patient with EGE presenting with concurrent acute pancreatitis and...

Eosinophilic gastroenteritis is a rare condition characterized by recurrent eosinophilic infiltration of portions of the GI tract and presenting with nonspecific GI symptoms in association with peripheral eosinophilia. Its etiology and pathogenesis remain unclear and its symptoms overlap with many GI and systemic diseases. Thus, both gastroenterologists and general internists need to be aware o...

Eosinophilic gastrointestinal disorder (EGID) is a rare disease in children that affects the bowel wall, with eosinophilic infiltration in the absence of any other causes for eosinophilia. The etiology remains unknown, but allergies and immunological imbalance are suspected triggers. We encountered a case of serosal EGID presenting as intractable vomiting and ascites in a 9-year-old girl, after...

We report here a case with hypereosinophilia and peripheral artery occlusion. A 32-yr-old Korean woman presented to us with lower extremity swelling and pain. Angiography revealed that multiple lower extremity arteries were occlusive. The biopsy specimen showed perivascular and periadnexal dense eosinophilic infiltration in dermis and subcutaneous adipose tissue. Laboratory investigations revea...
