Gaucher disease is the most common lysosomal storage disorder, it results from the inherited deficiency of the enzyme glucocerebrosidase, the accumulation of its substrate causes many clinical manifestations. Since the discovery of GBA gene, more than 200 different mutations have been identified, but only handful mutations are recurrent (N370S, L444P and(More)
Amyloidosis is a rare disease that results from the extracellular deposition of amorphous fibrillar protein. It is usually observed in a systemic form. Gastrointestinal involvement is frequent but peritoneal localization is unusual. A 43-year-old male was investigated for nephritic colic. Morphologic explorations revealed small intestine agglomerans in the(More)
The glycogen storage disease type Ia (GSD Ia) is a rare inherited disorder, with autosomal recessive determinism. It is characterized by hepatomegaly, short stature and hypoglycemia with lactic acidemia. The confirmation of diagnosis is based on the enzymatic assay performed on liver biopsy. For Tunisians patients, this biochemical test is performed abroad.(More)
BACKGROUND Osteosarcoma is a malignant tumor of mesenchymatous origin that chiefly affects the metaphysis of long bones. The extraskeletal form of the disease is rare, and even rarer is a cutaneous site, whether metastatic or primary. Herein, we report a new case of primary cutaneous osteosarcoma. PATIENTS AND METHODS A 54-year-old woman presented a hard(More)
Most mesenchymal tumours of the gastrointestinal tract are now referred to as gastrointestinal stromal tumours (GISTs). These tumours typically express c-kit (CD117) and CD34; 30-50% are (often focally) positive for alpha-smooth muscle actin, and all are negative for desmin and S100 protein. Recently, mutations in exon 11 of the c-kit gene have been(More)
The natural history and clinical presentation of the perinatal-lethal Gaucher's disease, a severe variant of acute type 2 Gaucher's disease, is quite different from classic type 2 Gaucher's disease. Rare reported patients had an overlapping phenotype between these two forms confirming that phenotyping may be difficult. Here we report three patients with an(More)
Congenital generalized lipodystrophy (CGL) is a rare disorder characterized by near complete absence of adipose tissue from birth. At least 2 genes located in 9q34 (AGPAT2) and 11q13 (Seipin) are implicated in type 1 and 2, respectively, and result in insulin resistance. We report here a novel case of CGL type 1 resulting from a novel homozygote mutation in(More)
AIM Our purpose is to study the aetiologies of congenital cataracts, and to establish an approach to decision making of etiological diagnosis. METHODS We included 85 children in a cross sectional study. The mean age was 4.5 years. These patients underwent a complete ophthalmologic and paediatric examination, and etiological investigation. RESULTS An(More)
BACKGROUND Cutaneous vasculitis has been mainly associated with hematologic cancer. The association of solid neoplasms with cutaneous paraneoplastic vasculitis is rare. We report a case of cutaneous leucocytoclastic vasculitis that revealed a gastric adenocarcinoma. CASE REPORT A 72-year-old man presented with an acute diffuse polymorphic eruption, with(More)
