A male preterm infant (born at 34 weeks, birth weight 2130 g) developed jaundice (total bilirubin 7.4 mg/dl), hepatosplenomegaly, thrombocytopenia (82,000/microliters) and a raised C-reactive protein (1.2 mg/dl). Although sepsis was suspected, no organism was demonstrated. When the mother visited the child for the first time after 2 weeks, she had florid hyperthyroidism. This explained many of the child's clinical features (poor weight gain, tachycardia, exophthalmos). Both mother and child had raised TSH receptor antibodies (mother: 684.6 U/l; 54.1 U/l, normal < 15 U/l), an increased free T4 and a suppressed TSH. Because of the tachycardia, the child was treated with propranolol (1 mg/kg.d for 5 weeks). He was also initially given Lugol's solution (25 mg iodide/kg.d for 1 week) and then propylthiouracil (7 mg/kg.d) because of the increasing total T3. L-Thyroxine replacement was subsequently required for a period of 2.5 weeks because of treatment-related hypothyroidism. Since stopping treatment (at 12 weeks of age), the child has developed normally.--Neonatal hyperthyroidism due to transplacental transfer of TSH receptor antibodies associated with maternal Graves' disease is a rare self-limiting condition. However, it may pose considerable danger to the child both in utero and postnatally (with a mortality if untreated of up to 20%). Interdisciplinary cooperation is essential.

Infantile malignant autosomal recessive osteopetrosis (ARO; OMIM 259700) has been reported to be associated with mutations in TCIRG1, CLCN7, or OSTM1. ARO caused by homozygous (or compound heterozygous) mutations in CLCN7, as described here, is usually diagnosed at birth or early in infancy due to generalized osteosclerosis and severe hematologic deficits. The maximal life expectancy of patients with ARO in the absence of bone marrow transplantation is thought to be 10 years. We report on a 25-year-old Thai man who is affected with ARO. Clinical features include proportionate short stature, vision impairment, esotropia, exophthalmos, mild hearing loss, and hepatosplenomegaly. Pancytopenia was present and the patient had frequent illnesses. Radiographs showed generalized osteosclerosis with almost no visible of bone marrow spaces. Dense maxilla and mandible with impacted and malformed teeth were observed. Multiple fractures were reported. He developed osteomyelitis of the mandible on four separate occasions, and partial mandibulectomy was performed. Molecular studies showed that there were no pathogenic mutations in TCIRG1. However, mutation analysis of CLCN7 revealed a homozygous missense mutation (p.Arg526Gln). This patient is, it appears, the longest lived individual with ARO ever reported. Evaluation of osteoclastogenesis in our patient demonstrated very large immature osteoclasts with a high number of nuclei.

A 33-year-old Chinese male patient with severe aplastic anemia received matched sibling allogeneic hematopoietic stem cell transplantation using antithymocyte globulin containing conditioning regimen after 4 months of unsuccessful treatment with cyclosporine A. Following transplantation, the patient was immunosuppressed demonstrated by intermittent infections, including a varicella 3 months after transplantation. Although DNA-STR results on day +30 confirmed complete donor engraftment, repeat DNA-STR analysis performed more than 3 months after transplantation showed a mosaic phenotype. Cyclosporine tapering commenced early, but the last DNA-STR result confirmed complete graft rejection. On day +198, the patient presented with fever, skin boil in the right temporal region, severe pancytopenia, intrabodominal lymphadenopathy and hepatosplenomegaly. Within 1 month, superficial lymphadenopathy and right exophthalmos developed. Excisional lymph node biopsy pathology confirmed Kaposi's sarcoma (KS). The patient succumbed due to intracranial bleeding as a result of thrombocytopenia. This is the first study of KS that developed following stem cell transplantation for severe aplastic anemia. The precipitating factors underlying KS development in this case and its differentiation from post-transplant lymphoproliferative disorders are analyzed.

Rosai-Dorfman disease (RDD) is a rare lymphoproliferative disorder with nodal and extranodal involvements. Here we report a case of RDD in a 15-year-old female who presented with epigastric pain, fatigue, Raynaud phenomenon in fingers, submandibular lymphadenopathy, proptosis, hepatosplenomegaly, and round shape painless patches on the extensor surfaces. Histological examination of the submandibular lymph nodes and skin biopsy demonstrated evidences of RDD. Patient was treated with prednisone and thereafter, with azathioprine. After one year, prednisone was discontinued and all of the symptoms and signs, except proptosis, were resolved. This report highlights the extranodal manifestations of RDD. The presentation, differential diagnosis, and treatment are discussed.

An infant presented with fever and purulent discharge from the left ear, proptosis of the right eye, and hepatosplenomegaly. She was diagnosed with acute monoblastic leukemia on morphological and flowcytometric analysis of the bone marrow. Karyotyping showed a jumping translocation (JT) involving the long arm of chromosome 1 as the sole cytogenetic abnormality in 29 metaphases. The patient died within 2 months of diagnosis. The presence of JT in a de novo infant AML as a sole cytogenetic abnormality indicates its possible role in leukemogenesis unlike previous reports that have implicated its role in tumor progression only.

We report the case of a 3-year-old child, who presented with lid swelling which progressed to proptosis of the left eye. He also had systemic symptoms of fatigue and weight loss. An examination revealed hepatosplenomegaly and lymph node enlargement. Investigations showed a peripheral smear with blast cells, which were also revealed through a bone marrow biopsy. A CT scan showed a mass lesion in the left orbit that had infiltrated into the surrounding tissues. He was diagnosed with acute lymphoblastic leukaemia (ALL) with left-sided orbital mass secondary to it. Haematogenous masses in the orbit are commonly due to granulocytic sarcomas, which are usually associated with acute myelogenous leukaemia (AML), not ALL, and are rare especially when they precede systemic disease.

A previously healthy eleven month old male Malay infant presented with fever, upper respiratory tract infection and right knee swelling. Pallor, bilateral proptosis, hepatosplenomegaly, multiple scalp swellings and a right cheek swelling were observed. Investigations revealed that he had acute monoblastic leukemia or FAB M5a. Immunophenotyping by flow cytometry showed that the blast cells were positive for CD45, CD13, CD33, HLA-DR, CDllc, CD71, EMA, and Cytokeratin. They were negative for CD34, CD19, CD10, CD22, CD2, CD3, CD4, CD7, CD8, CD61, NK, Glycophorin A, and CD14. The monoblasts were used to evaluate anti-EMA and anti-cytokeratin. They were unexpectedly found to be positive. Acute monoblastic leukaemias are well known to show extramedullary infiltration and this may be their primary mode of presentation. Thus, in immunochemostry, when using EMA and cytokeratin expression in the differential diagnosis of neoplastic diseases, it is important to consider that monoblasts may express these markers as illustrated by this case.

The authors report a case of a 58-year-old man with bilateral proptosis and signs of orbital inflammation without any associated systemic findings. MRI showed diffuse orbital infiltration. An intraconal orbital biopsy revealed polyclonal lymphoplasmacytic infiltration and non-necrotizing lymphoid small-vessel vasculopathy. The orbital symptoms resolved following a 2-week course of oral prednisone. Three months later, the patient experienced abdominal pain and weight loss. Ultrasonographic investigation showed hepatosplenomegaly, a retroperitoneal mass, and inguinal lymphadenopathy. A lymph node biopsy revealed a diffuse large B-cell lymphoma. The patient underwent chemotherapy but died 6 months later with metastatic disease. This case suggests that diffuse orbital inflammation with nonspecific vasculitis may be an early paraneoplastic finding associated with diffuse large B-cell lymphoma.

A 65-year-old man presented with a 2-year history of severe bilateral proptosis, palpable lymphadenopathy and moderate hepatosplenomegaly. A blood test was positive for hepatitis C infection. CT showed palpebral infiltrative lesions with regional progression through the temporal and masticatory spaces to the pharynx and hypopharynx causing almost complete airway obstruction. A palpebral biopsy was consistent with low-grade Bcl-2+ extra-nodal MALT non-Hodgkin B-cell lymphoma. The patient received six cycles of rituximab-based chemotherapy with clinical remission at 9-month follow-up. Bilateral proptosis is a rare presentation of several diseases. When brain CT excludes cavernous sinus pathology, thyroid ophthalmopathy or haematological malignancy should be considered.

Acute monocytic leukaemia (French-British-American classification: AML-M5b) is characterised by a predominance of cells of the monocytic lineage on bone marrow examination. Furthermore, a discerning feature is its tendency for tissue infiltration. While gum hypertrophy and hepatosplenomegaly are common, ocular involvement is rare. Here, we present a case of a 75-year-old man referred with proptosis and monocytosis-subsequently diagnosed as AML-M5b, whose disease course was distinguished by extensive tissue invasion (ocular, pulmonary, liver, spleen). Cytogenetics and molecular tests were consistent with blastic transformation of previously undiagnosed chronic myelomonocytic leukaemia, supported by the presence of long-standing, low-grade monocytosis. Notably, a BRAF V600E mutation was also detected-an oncogenic driver previously reported in de novo and therapy-related, but not chronic myelomonocytic leukaemia-transformed, AML-M5b. While an initial response to cytoreductive treatment was observed, his tissue-invasive disease soon progressed with worsening pulmonary infiltrates, disseminated intravascular coagulation and renal failure, resulting in death.
