Griscelli syndrome: Report of Three Cases

The clinical features of three children with Griscelli syndrome and autopsy findings of two are presented. The patients were 5 years, 9 months, and 3 months old, respectively. Clinical features included partial albinism, hepatosplenomegaly, and various neurological symptoms. Light and electron microscopic studies of the skin were compatible with Griscelli syndrome. Postmortem examination of the viscera and central nervous system revealed lymphohistiocytic infiltration with erythrophagocytosis. Bilateral diffuse involvement of the central nervous system, cranial nerve, and spinal cord was detected in both cases.

Intracardiac thrombosis diagnosed by echocardiography in childhood: predisposing and etiological factors

Eleven cases of intracardiac thrombi caused by different factors including protein-C deficiency are presented for discussion of the etiology and predisposing factors of intracardiac thrombi during infancy and childhood, and to stress the importance of protein-C deficiency as an etiological factor. Thrombi were localised in the left heart in five patients and right heart in five patients. One patient had both-sided thrombi. Four of our patients had dilated cardiomyopathy, one had mitral valve hypoplasia, and one had pulmonary valvar stenosis as the predisposing factors for thrombus formation. In three patients whose cardiac anatomies were completely normal, we determined protein-C deficiency as an etiological factor of thrombus formation. One of these had congenital protein-C deficiency and the other two had acquired temporary protein-C deficiency due to sepsis. In conclusion we recommend that protein-C deficiency should be investigated as an etiological factor in all cases of intracardiac thrombi irrespective of whether or not another predisposing factor is identified.

Chest wall hamartoma: An alarming chest lesion with a benign course

Chest wall hamartoma is a very rare mass lesion of the chest wall that is manifest at birth or in early infancy with deformity of the thoracic wall and/or varying grades of respiratory distress. The authors report on an 11-month-old infant presenting with chest wall hamartoma who was treated by en bloc excision of the lesion including the involved ribs. They emphasize the importance of early and complete excision of the lesion even in minimally symptomatic patients to avoid lethal respiratory complications, more severe postoperative orthopedic problems, and malignant transformation.

Nonsyndromic paucity of interlobular bile ducts: clinical and laboratory findings of 10 cases.

BACKGROUND Reports concerning nonsyndromic paucity of the interlobular bile ducts are not common. METHODS The clinical, biochemical, and histological features of ten such children were described. RESULTS All presented with jaundice, starting in the first month in seven and in the fourth, seventeenth, and thirtieth month in the others. Alcoholic stools were present intermittently in seven and persistently in three patients. Pruritus was a prominent symptom in five. Liver function tests were abnormal in all but one. Liver biopsies were performed at ages of 20 days to 3 years (median 5 months). In addition to a paucity of interlobular bile ducts, histology revealed intracellular cholestasis in all, portal fibrosis in four, and regenerative nodules in two patients. Complications of fat-soluble vitamin deficiency occurred in seven. Therapy consisted of supplementation of those vitamins and administration of cholestyramine, phenobarbital, prednisolone, or ursodeoxycholic acid. While one child had a successful orthotopic liver transplantation, three died. Consanguinity rate was 80% among the parents, and five of the patients had siblings with similar symptoms. CONCLUSIONS Prognosis of these patients is variable. Differentiation from other forms of cholestasis is important especially to avoid surgery.

Familial intestinal polyatresia syndrome.

Familial multiple‐level intestinal atresia is a rare syndrome with autosomal recessive inheritance. Only a few well‐documented families have been reported in the medical literature. In this article two new cases from a consanguineous couple are presented. These are the first reported cases of Familial Intestinal Polyatresia Syndrome from Turkey. The importance of this report is that the recognition of multiple intestinal atresias as an invariably fatal syndrome will be helpful for genetic counselling and attempts at early prenatal diagnosis for successive pregnancies in these couples.

Portal vein thrombosis in association with factor V Leiden mutation in a patient with hepatocellular carcinoma.

We report a case of hepatocellular carcinoma associated with portal vein thrombosis. Analysis of whole cellular DNA demonstrated heterozygosity for the factor V Leiden mutation. The patient also had marked protein C deficiency. The presence of the mutation associated with protein C deficiency may increase the risk of thrombosis in this patient with hepatocellular carcinoma.

Myelodysplastic syndrome associated with Griscelli syndrome

Myelodysplastic syndrome (MDS) in children has been reported to be associated with various constitutional anomalies; however, it has not been described previously in patients with Griscelli syndrome (GS). In this report, we present a case with GS and refractory anemia with an excess of blasts. We believe that careful evaluation of peripheral blood and bone marrow could increase the number of patients who are found to have GS-associated MDS.

Lethal hydrops fetalis due to congenital dyserythropoietic anemia in a newborn: Association of a new skeletal abnormality

Congenital dyserythropoietic anemias (CDAs) area group of hereditary refractory anemias characterized by ineffective erythropoiesis, typical morphological abnormalities of erythroblasts, a low or no reticulocyte response, hyperbilirubinemia, and splenomegaly. A massive hydropic newborn born with a very severe anemia (Hb 4.8 g/dL), diffuse edema, hepatosplenomegaly, ascites, pulmonary edema and respiratory distress, and shortness and hallux varus deformity of the great toe of the right foot was diagnosed to have congenital dyserythropoietic anemia on the basis of the hematological (macrocytosis, anisopoikilocytosis, fragmented red cells and erythroblastosis in the peripheral blood, and erythroid hyperplasia with erythroblastosis and erythroblasts with double nuclei and thin chromatin bridges connecting these nuclei in the bone marrow) and serological (negative acidified serum lysis test and no agglutination with anti-i antibodies) findings. In this article the seventh case of neonatal congenital dyserythropoietic anemia presenting with a very severe(lethal) form of hydrops fetalis and a new (hallux varus) deformity of the great toe of the right foot is presented. Congenital dyserythropoietic anemia should be considered in the differential diagnosis of hydrops fetalis presenting with a very severe anemia and a skeletal abnormality of the great toe.

Osteogenic sarcoma of the distal femur in a young child

Osteogenic sarcoma of the distal femur of a 2½-year-old girl is described. This case is noteworthy because of the young age of the patient.

Fatal Cytophagic Histiocytic Panniculitis

Abstract:  Individual cases of so‐called Weber‐Christian disease with a bleeding diathesis have been reported for several years. These were originally diagnosed as Weber‐Christian disease, but have been recategorized on review as a chronic, visceral, and cutaneous histiocytic (cytophagic) panniculitis, progressing to liver dysfunction and jaundice and a terminal hemorrhagic diathesis. We report here a rare catastrophic form of systemic panniculitis in an adolescent girl. Despite compelling clinical evidence, the diagnosis was made only on postmortem biopsies.
