A 52-year-old Japanese woman with the chief complaint of marked swelling of her upper eyelids and a mass over the bulbar conjunctiva is reported. She previously noticed frequent purpura after minimal trauma, which was resolved shortly after taking some ascorbic acid. Laboratory data showed Ig-G kappa type M-protein in the serum and kappa type Bence-Jones protein in the urine by immunoelectrophoresis. Systemic examination showed mild hepatosplenomegaly, 1st degree of AV block, and a mild increase in plasma cells in the bone marrow biopsy. Histologically, the whole dermis of the eyelid skin and conjunctiva was replaced by a large quantity of amorphous, eosinophilic substances, which were diffusely positive with Direct Fast Scarlet 4BS. Immunohistochemical staining was positive for anti-amyloid P component antibody. Typical amyloid fibrils were proved by electron microscopy. She was finally diagnosed as primary systemic amyloidosis with diffuse swollen eyelids and conjunctival mass, symptoms which in primary systemic amyloidosis are very rare.

Primary neoplasms of the pancreas are rare in children. One variant of these tumors is pancreatoblastoma, comprising 0.5% of epithelial tumors of the pancreas. It usually affects children at 1-8 years of age, with quite equal sex ratio. The tumor can be found at any site of pancreas, but it most commonly arises in the head of pancreas. Histopathologically, pancreatoblastoma is an encapsulated tumor with distinct organoid structures and sometimes squamoid corpuscles. Acinar cells with zymogen granules are occasionally found. The tumor has favorable prognosis. We present a 14-year-old female who was admitted due to prolonged jaundice for about 2 months. Physical examination revealed pale conjunctiva, yellowish skin color and hepatosplenomegaly. Abdominal sonography and CT scan showed dilated common bile duct and a tumor mass about 2 x 2 cm in dimension located a pancreatic head. She received surgical operation to relieve obstructive jaundice and later Whipple's operation for radical resection. Six months after operation, the patient received the examination of abdominal sonography, CT scan and gallium tumor scan but there was no evidence of local recurrence or distant metastasis. Now the patient is living well for more than one year. Because of its rare occurrence, we demonstrate this case and review the literature.

A 79-year-old male was admitted to our hospital because of general fatigue and night sweat. Physical examination showed generalized superficial lymphadenopathy, marked splenomegaly, and tumors in the conjunctiva and the abdomen. Chest X-ray and computed tomography (CT) revealed pleural effusion and intrathoracic lymphadenopathy. Abdominal ultrasonography and CT showed hepatosplenomegaly and intraperitoneal tumors. Upper gastrointestinal fiberscopy revealed multiple polypoid lesions and ulcers in the duodenum and the stomach. Involvement of relatively small-sized lymphocytes with cleaved nuclei was identified in each biopsied specimen from a cervical lymph node, a tumor in the conjunctiva, gastrointestinal polypoid lesions, and the bone marrow. Surface marker analysis of abnormal lymphocytes in the bone marrow revealed that CD5, CD19, and CD20 were strongly positive, but CD23 was weakly positive. Although (11:14)(q13:q32) translocation was not identified by chromosome analysis of bone marrow cells, Northern blot analysis of bone marrow cells revealed overexpression of the PRAD1 oncogene. Diagnosis of mantle cell lymphoma (MCL) was made. Combination chemotherapy by cyclophosphamide and vincristine was not effective, but etoposide perorally given at a dose of 50 mg per day was effective. In MCL, extranodal involvement of a digestive tract and bone marrow is well known. This case suggests that involvement of multiple organs including lacrimal glands and pleura could be characteristic of MCL cells.

The patient is a 12-year-old boy with acute mixed lineage leukemia (AMLL) and with a rare karyotype of trisomy 6. He was referred to our hospital with gingival swelling, bleeding at the conjunctiva and huge hepatosplenomegaly. Complete blood count revealed leukocytosis with 79% blasts, anemia and thrombocytopenia. Bone marrow examination revealed 82.5% blasts which were morphologically judged as M1 according to the French-American-British classification. Immunophenotyping of leukemic cells showed the presence of CD2, CD7, CD19 and CD13 antigens, suggesting the diagnosis of AMLL. Cytogenetic analysis revealed a single abnormal karyotype of 47,XY,+6,add(15)(q22) which was successfully detected by fluorescence in situ hybridization (FISH) with the probe mapping at the alpha-satellite region of chromosome 6. Although the patient was treated with several chemotherapy regimens, he could not achieve complete remission and he died of progressive disease 11 months after admission. Fluorescence in situ hybridization analysis was very informative in assessing the residual leukemic cells in interphase during his clinical course.

Ocular, peroral, intraperitoneal, intramuscular, and subcutaneous inoculation of severe combined immunodeficient (SCID) mice with spores of the human isolate (CDC: V404) of Brachiola algerae (syn. Nosema algerae) (Phylum Microspora) revealed that the microsporidium develops in viscera of the immunodeficient mouse host, but only after the ocular administration of spores. It is hypothesized that the physico-chemical milieu of the conjunctiva and cornea helped to adapt the originally 'poikilothermic microsporidian' to the conditions within the homoiothermic organism. Ocular application of spores caused no clinical signs of disease at the application site. However, severe infection in the liver was found 60 days after infection, manifested as hepatosplenomegaly and multifocal miliary necroses and granulomas containing parasites. No microsporidia were found in any other tissues. Transmission electron microscopy revealed characteristic tubulovesicular 'secretory materials' on the plasma membrane of all developmental stages of B. algerae except sporoblasts and spores. These formations increase the parasite surface and allow more efficient metabolic communication of the parasite with the host cell. It is hypothesized that the presence of these structures is a factor helping the parasite to grow in a variety of hosts and tissues. Ultrastructural characters support the likelihood that B. algerae and B. vesicularum are conspecific, and that there exists a relationship between species of the genera Brachiola and Anncaliia.

The detection of neurodegenerative and neurometabolic diseases in children relies on a high index of suspicion as most will present as common paediatric problems such as recurrent vomiting, feeding problem, failure to thrive, sepsis, or developmental delay. Alternatively, children may present with an acute encephalopathy or with a chronic progressive encephalopathy. Clinical clues suggestive of neurometabolic disorders include encephalopathic features such as microcephaly, macrocephaly, developmental regression, developmental arrest, change in sensorium, seizures, hypotonia, hypertonia, abnormal eye signs; also extrapyramidal or cerebellar signs and systemic features like abnormal respiration, hepatosplenomegaly, abnormal hair, liver dysfunction, renal tubular dysfunction, cardiomyopathy, and feeding difficulties or growth problems. Initial screening include tests for acidosis, ketosis, hyperlacticemia, and hyperammonemia. Further investigations should amino acid chromatography, assays of organic acids, specific enzyme assay of white cell or fibroblast culture, and histopatholgy of cell and tissue biopsy (white blood cell, skin, muscle, conjunctiva, bone marrow, liver, rectum, or brain). The correct diagnosis holds implications for targeted therapeutic intervention, genetic counselling, and possibly, prenatal diagnosis.

Diagnosis of tuberculosis (TB) in children is usually based on presumptions from several elements: clinical picture and course, x-rays, tuberculin test, and culture of pathology later on. TB is usually found in a child because of symptoms of primary disease, or through case-finding of a contact. TB is children is often a primary infection and may be gradual or acute in onset. Some of the symptoms of primary TB are low-grade fever, pallor, fatigue, and anorexia. The child may have erythema nodosum, a yellow module on the conjunctiva, hilar or mediastinal lymphadenopathy, a primary TB complex on the lung (3-10 mm), segmental density, or a positive PPD test. Children with pulmonary disease do not have adult-type cavity lesions, but may have a primary cavity that drains into the bronchi, mechanical complications, fistulas, or atelectasis. Acute TB often appears as meningitis. The pathognomonic signs are cerebrospinal fluid high in lymphocytes with very high albumin (0.6-2 g) and low glucose (0.4-0.2 g/l). TB organisms are rarely seen, but may be cultured. TB meningitis is also notable for choroidal tubercles, which are yellow nodules visible in the fundus. These presumptive signs, as well as increasing neurological findings, prompt immediate treatment. Children also may have acute miliary TB, marked by high fever, gastrointestinal symptoms, hepatosplenomegaly, dyspnea, cyanosis, and respiratory distress, with characteristic diffuse grainy spots on the chest x-ray. A child may have both conditions and may also have localized TB infection elsewhere. Thus, clinical findings may point to possible cultures of urine, gastric lavage, pleural fluid or biopsy, pericardial fluid, bone marrow, or ascitic fluid, any of which should be cultured to rule out other causes. The most common sites for extra-pulmonary TB are cervical nodes, spine, knee. shoulder, hip and peritoneum. Pelvic and urinary tract infections are rare in children.

The literature was reviewed to study cases of intoxication with systemic dermatitis associated with exposure to trichloroethylene. The average age of patients in the reports reviewed to date was twenty-nine; these diseases were found in relatively young persons and no difference was found according to gender. Many cases occurred within one month after the onset of exposure to trichloroethylene, and were accompanied by hepatitis, jaundice, hepatomegaly or hepatosplenomegaly. Most of the patients had no history of drug abuse or herpes infection. The level of exposure to trichloroethylene was not recorded in many cases, but ranged from less than 9 ppm to 800 ppm. In the severest cases, the lesions involved mucous membranes such as the conjunctiva and oral cavity, and the patients were diagnosed with Stevens-Johnson syndrome, but the etiology of the disease after trichloroethylene exposure remains unclear. Since several drugs have also been shown to cause systemic dermatitis with hepatitis, susceptibility factors are discussed. Many patients were found to have the slow acetylator genotype of N-acetyltransferase (NAT) 2, suggesting that the NAT2 genotype is a susceptibility factor. This hypothesis may also be applicable to trichloroethylene because NAT is involved in the glutathione-mediated metabolism.

Ataxia-telangiectasia (AT) and hyper-immunoglobulin M (HIGM) syndrome are both primary immunodeficiency diseases caused by different genetic defects. While a small proportion of AT patients have increased serum immunoglobulin (Ig) M concentrations during the course of a disease, a high level of IgM at onset is rare. We report the case of an 8-year-old girl who had experienced recurrent respiratory infection, cutaneous abscesses, and hepatosplenomegaly since the age of 2 years. She was diagnosed with HIGM based on the results of immunological studies, including low IgG and IgA levels and raised serum IgM concentrations. However, at the age of 4 years, a neurological examination revealed gait disturbance and telangiectatic lesions on the conjunctiva; therefore, a diagnosis of AT was suggested. In spite of regular intravenous immunoglobulin infusions and antimicrobial prophylaxis, the patient experienced several episodes of respiratory infection and eventually died of respiratory failure at the age of 8 years. Further molecular analysis revealed a novel homozygous missense mutation in exon 53 (c.8250C>T, p.2622Ala>Val) of the ATM gene. Patients with AT and the HIGM phenotype may not develop clinical characteristics of AT for some time. While patients with AT and increased serum IgM levels could have a considerably more severe disease course and a shorter survival, IgM levels could be considered a prognostic factor.

A 7-year-old girl was admitted to Xiangya Hospital due to systemic lymphadenectasis for 2 months and skin ecchymosis for 3 days. Nine months ago, the girl experienced painless nodules in the left lower extremity with no apparent causes. Three months later, dermatorrhagia and ecchymosis occurred in many regions such as the periocular areas, conjunctiva, oral mucosa, perineal area, and groin, with a "raccoon sign" in both eyes; superficial lymphadenectasis and hepatosplenomegaly were also observed in many regions. The pathological sections for the skin nodules showed malignant tumors in lymphohematopoietic cells, and in combination with clinical manifestations, immunohistochemistry, and positive results for CD4, CD56, and CD123 by bone marrow flow cytometry, the girl was diagnosed with blastic plasmacytoid dendritic cell neoplasm. Then high-risk ALL regimen was applied as the chemotherapy for this girl. At present, the girl has been followed up for 3 months; ecchymosis has disappeared, and the enlarged lymph nodes have shrunk. No abnormal cells have been found in bone marrow morphological examination, and bone marrow flow cytometry has shown that primitive precursor cells account for 1.5% and express CD33, CD34, CD123, and CD117.
