Abstract
Mastocytosis is a rare and heterogeneous disease characterized by various clinical and biological features that affect different prognoses and treatments. The disease is usually divided into 2 principal categories: cutaneous and systemic disease (SM). Clinical features can be related to mast cell (MC) mediator release or pathological MC infiltration. SM is a disease often hard to identify, and the diagnosis is based on clinical, biological, histological, and molecular criteria with different specialists involved in the patient’s clinical work-up. Among all manifestations of the disease, gastrointestinal (GI) symptoms are common, being present in 14%-85% of patients, and can significantly impair the quality of life. Here we review the data regarding GI involvement in SM, in terms of clinical presentations, histological and endoscopic features, the pathogenesis of GI symptoms, and their treatment.

Abstract
Simple Summary In this review will discuss the clinical presentation, pathophysiology, and role of imaging in detection and extent estimation of the systemic involvement of the disease, in addition to demonstration of appearance on varying imaging modalities. Familiarity with the potential imaging findings associated with mastocytosis can aid in early disease diagnosis and classification and accordingly can lead directing further work up and better management. Abstract Mastocytosis is a rare disorder due to the abnormal proliferation of clonal mast cells. Mast cells exist in most tissues, mature in situ from hematopoietic stem cells and develop unique characteristics of local effector cells. Mastocytosis develops by activation mutation of the KIT surface receptor which is involved in the proliferation of a number of cell lines such as mast cells, germ cells, melanocytes, and hematopoietic cells. It manifests as two main categories: cutaneous mastocytosis and systemic mastocytosis. Imaging can play an important role in detection and characterization of the disease manifestation, not only by radiography and bone scans, but also magnetic resonance imaging and computed tomography, which can be more sensitive in the assessment of distinctive disease patterns. Radiologists should be aware of various appearances of this disease to better facilitate diagnosis and patient management. Accordingly, this review will discuss the clinical presentation, pathophysiology, and role of imaging in detection and extent estimation of the systemic involvement of the disease, in addition to demonstration of appearance on varying imaging modalities. Familiarity with the potential imaging findings associated with mastocytosis can aid in early disease diagnosis and classification and accordingly can lead directing further work up and better management.

Abstract
Rapidly progressive ascites is a frequent clinical manifestation of advanced abdominal malignancies or portal hypertension due to liver diseases. We report a case of 61-year-old man who presented with rapidly progressive ascites. The presence of ascites, generalised lymphadenopathy, osteosclerosis on imaging and hepatosplenomegaly initially pointed towards the diagnosis of advanced high-grade lymphoma or accelerated myeloid neoplasm. Lymph node biopsy revealed infiltration by CD45, cKIT and CD30; tryptase and toluidine blue-positive mast cells (MCs). Bone marrow examination revealed infiltration by MCs and next generation sequencing revealed the pathognomic exon 17 D 816V KIT mutation. The patient was started on weekly pegylated interferon with significant symptom relief. Systemic mastocytosis should be considered as a differential diagnosis in a clinical case of ascites of unknown aetiology even in the absence of typical skin manifestations.

Abstract
Systemic mastocytosis (SM) is a hematologic disease with a wide range of clinical courses ranging from an indolent condition with normal life expectancy to exceedingly aggressive disorder with a poor prognosis. The symptoms and signs of SM result from the release of mast cell mediators with heterogeneous functions, and/or organ damage from neoplastic mast cell infiltration, or both. Diagnostic criteria for SM are well-defined by the World Health Organization (WHO). However, the diagnosis of SM can be difficult when especially it is not in the differential diagnosis. Routinely used radiologic techniques (e.g., X-ray, ultrasound, CT scans can show findings such as lytic-, sclerotic- or mixed-bone lesions, splenomegaly, hepatomegaly, retroperitoneal or periportal mesenteric lymphadenopathy, and omental thickening). It is essential to emphasize that the constellation of these radiologic findings should strongly concern of SM, especially in patients who also have a skin rash, allergic reactions, gastrointestinal tract symptoms (lasting, intermittent nausea, diarrhea), paroxysmal tachycardias, unexplained weight loss, persistent bone pain, cytopenias, liver dysfunction, eosinophilia. These findings, even coincidentally noted, will likely lead to a tissue biopsy, which reveals diagnosis (as we discussed and illustrated some tissue biopsies here). Moreover, the role of MRI and new techniques such as [18-fluorodeoxyglucose positron emission computed tomography, fibroscan] in the diagnosis of SM have been discussed. Furthermore, we reviewed the use of radiologic methods to evaluate treatment response and prognostication of SM..

Abstract
Mast Cell Leukemia (MCL), a rare subtype of systemic mastocytosis is defined by bone marrow involvement as atypical and aleukemic mast cells, if more than 20% and less than 10% of peripheral WBCs are mast cells, respectively. We met a case of aleukemic MCL presenting with anemia and ascites for 2 years, referred for BM evaluation, suspicious of leukemia. Our findings included BM involvement by diffused aggregates of oval- and spindle-shaped atypical mast cells, lacking mature mast cells and other hematopoietic cells. The mast cells were absent in peripheral blood smear. Further assessments showed positive reaction of mast cells metachromatic granules with Tryptase, Giemsa and Toluidine blue stains, the expression of CD117/KIT and CD45 by immunohistochemistery, and elevated level of serum Tryptase. Radiologic investigations revealed generalized lymphadenopathy, and massive hepatosplenomegaly, followed by the cervical lymphadenectomy, and liver wedge biopsy. Suspicious peritoneal lesions were identified and underwent excisional biopsy. Microscopic evaluations showed lymph nodes and liver involvement by cancer cells and the same features in peritoneal seeding. Multiple organs damage progressed in few months and the patient died despite surgery and chemotherapy. In conclusion, we report an extremely rare case of aleukemic MCL with multiple organs damage such as liver, peritoneum, spleen, gastrointestinal tract and BM, presenting by ascites. According to this case and previous parallel studies, we suggest some clinicopathologic features in favor of poor prognosis, including the presence of multiple organs damage, hepatomegaly, ascites, peritoneal seeding, the absence of mature mast cells and other hematopoietic cells in the BM, and elevated serum Tryptase level.

Abstract
Systemic mastocytosis is a rare infiltrative disease involving the skin, bone marrow, digestive system, and liver. We report a case of a 59-year-old male who presented with a massive variceal bleed without any evidence of cirrhosis; however was later found to have severe perisinusoidal fibrosis with mast cells in portal tracts on liver biopsy and hypercellular mast cell infiltrated bone marrow. This rare case describes an out-of-the-ordinary reason of variceal bleeding with preserved liver function due to non-cirrhotic portal hypertension.

Abstract
Hepatic involvement in aggressive systemic mastocytosis (ASM) is relatively common, and the main clinical features of this disease include hepatomegaly, portal hypertension, ascites, and fibrosis. Cirrhosis is a rare ASM symptom. We report an ASM case that initially mimicked cirrhosis based on clinical and radiographic analyses. The portal tract was expanded by mononuclear inflammatory cells, and an increase in collagen amount was observed in routine histological sections of the biopsied liver. A diagnosis of systemic mastocytosis (SM) was made after ancillary tests for mast cells using bone marrow aspirates. Extensive involvement of the liver and gastrointestinal tract was observed. Clinicians and pathologists need to consider ASM as a diagnosis or differential diagnosis in a clinical case of cirrhosis with unknown etiology. The diagnosis can be confirmed or disregarded by immunohistochemical staining and molecular analysis.

Abstract
Reported herein is an autopsy case of mast cell leukemia, a rare form of systemic mastocytosis, complicated with portal hypertension. A 52-year-old woman presented with urticaria-like skin symptoms, anemia, and thrombocytopenia. Atypical mast cells (CD2+, CD25+, CD117+) with toluidine blue metachromasia were found in the peripheral blood and on bone marrow aspiration smears. Chemotherapy with cytosine arabinoside and idarubicin was ineffective and the patient died of multi-organ failure with rapidly progressing hepatosplenomegaly and large-volume ascites 3 months after admission. At autopsy the bone marrow, spleen, liver, and lymph nodes were extensively infiltrated by atypical tumor cells with occasional bi- or multi-lobated nuclei. They were positive for mast cell tryptase and possessed an activating mutation of the c-kitgene (D816V). Ascites (2200 mL) and non-ruptured esophageal varices with submucosal hemorrhage indicated the presence of severe portal hypertension. Although there was no evidence of liver cirrhosis, the hepatic sinusoids were clogged with tumor cells, with a tendency to be more severe in the perivenular areas, and the lumens of central veins were obliterated by tumor cell infiltration. The present case demonstrates that non-cirrhotic portal hypertension due to blocking of sinusoidal and venous flow could be a serious complication in mast cell leukemia.

Abstract
Arterial vasodilation is common in end-stage liver disease, and systemic hypotension often may develop, despite an increase in cardiac output. During the preparation for and the performance of orthotopic liver transplantation, expected and transient hypotension may be caused by induction agents, anesthetic agents, liver mobilization, or venous clamping. A mild decrease of the already low systemic vascular resistance is often observed, and intermittent use of short-acting agents for vasopressor support is not uncommon. In this report, we describe a patient with unexpected and prolonged hypotension due to vasodilation during and after orthotopic liver transplantation. The preoperative end-stage liver disease evaluation, intraoperative events, and intensive care unit course were reviewed, and no cause for the vasodilation and prolonged hypotension was evident. The explant pathology report was later available and showed systemic mastocytosis. We hypothesize that the unexpected hypotension and vasodilation were caused by mast cell degranulation and its systemic effects on arterial tone.

Abstract
Liver fibrosis represents a major worldwide health care burden. The last 15 years have seen a rapid growth in our understanding of the pathogenesis of this clinically relevant model of inflammation and repair. This work is likely to inform the design of effective antifibrotic therapies in the near future. In this review, we examine how the innate and adaptive immune response interacts with other key cell types in the liver, such as the myofibroblast, regulating the process of hepatic fibrosis and, where relevant, resolution of fibrosis with remodelling. Emphasis is placed on the increasing knowledge that has been generated by the use of transgenic animals and animals in which specific cell lines have been deleted. Additionally, we review the increasing evidence that, although significant numbers of wound-healing myofibroblasts are derived from the hepatic stellate cell, significant contributions may occur from other cell lineages, including those from distant sites such as bone marrow stem cells.

Abstract
BACKGROUND Infantile cortical hyperostosis (ICH) is benign and self-limiting when it presents near or after birth but is usually lethal when it presents earlier. METHODS We present the clinical, ultrasonic, radiographic and pathologic findings in an instructive case of early onset prenatal ICH. RESULTS A 40-year-old G2P1 woman delivered spontaneously at 22 weeks' gestation. Prenatal ultrasounds showed rib and mandibular abnormalities as well as short humeri. Post-mortem radiographs showed asymmetric hyperostosis in long bones, mandible, scapulae and pelvis with sparing of spine, hands, feet and skull. The affected skeleton showed marked bony sclerosis and ballooning of the diaphyses of the long bones with periosteal sclerosis. A complete autopsy showed characteristic histologic findings in affected bones. Previous reports at 20+ weeks have described anasarca, fetal hydrops, hepatomegaly, and pulmonary hypoplasia. In our case, there was no hydrops/anasarca; hepatomegaly, due to massive extramedullary hematopoiesis with marked myeloid hyperplasia, combined with ribcage abnormalities, caused mild pulmonary hypoplasia. CONCLUSION We hypothesize that early onset fetal ICH is usually lethal because massive hepatic myeloid hyperplasia sequentially causes: (1) hepatomegaly and, in conjunction with rib abnormalities, mild pulmonary hypoplasia, (2) sinusoidal and pre-sinusoidal portal hypertension followed by ascites/hydrops, and (3) ascites/hydrops-induced severe pulmonary hypoplasia.

Abstract
Recent studies have shown that involvement of the gastrointestinal tract is much more frequent than originally reported in patients with systemic mastocytosis. Seventy percent to 80% of patients with systemic mastocytosis are found to have gastrointestinal symptoms when a careful history is taken, and abnormalities in the gastrointestinal tract are frequently detected by endoscopic studies, functional studies of absorption, and barium studies. Because of the rarity of the disease, there are few prospective studies of gastrointestinal involvement, so the actual frequency of upper and lower gastrointestinal lesions is unknown. Furthermore, there have been no studies correlating endoscopic abnormalities of the lower gastrointestinal tract with the presence or absence of diarrhea, which is a frequent symptom (mean, 43% [range 14%-100%]). A review of gastric acid studies reveals that a proportion of patients develop gastric acid hypersecretion because of the hyperhistaminemia, which can result in ulcer disease that in turn can cause dyspeptic pain, small intestinal mucosal damage, and malabsorption. In some patients gastric acid hypersecretion in the range seen in Zollinger-Ellison syndrome can develop. A number of studies suggest that the prevalence of peptic ulcer disease has been underestimated in these patients and is certainly higher than the general population. The exact physiologic basis for the diarrhea or nondyspeptic abdominal pain remains largely unknown in these patients. Whereas some studies suggest small intestinal mucosal abnormalities are responsible for most cases of malabsorption not associated with gastric acid hypersecretion, this supposition also remains unproven. Hepatomegaly, portal hypertension, splenomegaly, and ascites occur frequently in patients with systemic mastocytosis, especially those with category II through IV disease. Whereas the histology of the liver and spleen and alterations in hepatic function studies have been well studied, the pathogenesis of each of these abnormalities has not been well studied, and almost all the information comes from a few well-studied case reports.

Abstract
Portal hypertension was observed in a 17-year-old girl with urticaria pigmentosa since 2 months of age. Liver biopsies showed portal and sinusoidal infiltration with mast cells although spleen biopsies showed only fibrosis. CONCLUSION. Portal hypertension is a complication of systemic mastocytosis that can lead to death. Treatment with interferon alpha might be effective.
