We present the unusual case of a 16-year-old girl with T-cell acute lymphoblastic leukemia (ALL) with an early thymocyte immunophenotype without myeloid markers, who after 13 months of complete hematological remission relapsed as acute myelogenous leukemia (AML) with minimal differentiation and died of her disease. Whether the AML represented a relapse with lineage switch of the original immature T-cell clone or a new secondary malignancy, could not be proven due to the absence of molecular or clonal markers. This report suggests that a subset of CD7+ T-cell leukemias without mature T-cell antigens (CD4-, CD8-) are minimally differentiated and can relapse as AML.
Graft-versus-host disease (GVHD) is a frequent cause of morbidity and mortality after bone marrow transplantation. Acute GVHD most commonly involves the skin, gastrointestinal tract, and liver. Involvement of other organ systems is rare and remains controversial. We report a patient with GVHD who suffered a fatal ventricular arrhythmia shortly after bone marrow transplantation. Autopsy of the heart showed lymphocyte infiltration. Investigations for cardiotrophic viruses were negative, and chimerism analysis of the heart showed both donor and recipient DNA. We conclude that the cause of death was possibly graft-versus-host disease of the heart. A review of the literature revealed a total of 14 cases of possible cardiac GVHD. All but one of the reported cases have occurred in pediatric patients and six of those patients died, suggesting that this may be a rare but frequently fatal complication of pediatric allogeneic stem cell transplant.
AIM: To analyse the pattern of uveitis in a referral centre in Tunisia, North Africa. METHODS: The study included 472 patients with uveitis examined at the Department of Ophthalmology of Monastir (Tunisia) from January 1992 to August 2003. All patients had a comprehensive ocular and systemic history, including an extensive review of medical systems. Complete ophthalmic examination was performed in all cases, including best-corrected Snellen visual acuity, slit-lamp examination, applanation tonometry, and dilated fundus examination with three-mirror lens. Standard diagnostic criteria were employed for all syndromes or entities of uveitis. RESULTS: The mean age at onset of uveitis was 34 years. The male-to-female ratio was 1:1.1. Uveitis was unilateral in 282 patients (59.7%) and bilateral in 190 patients (40.3%). Anterior uveitis was most common (166 patients; 35.2%), followed by posterior uveitis (133 patients; 28.2%), panuveitis (100 patients; 21.2%), and intermediate uveitis (73 patients; 15.5%). A specific diagnosis was found in 306 patients (64.8%). The most common cause of anterior uveitis was herpetic uveitis (56 patients; 33.7%). Toxoplasmosis was the most frequent cause of posterior uveitis (51 patients; 38.3%). Intermediate uveitis was most commonly idiopathic (63 patients; 86.3%). Behçet's disease was the most common cause of panuveitis (36 patients; 36%), followed by Vogt-Koyanagi-Harada (VKH) disease (15 patients; 15%). A total of 16 patients (3.4%) suffered from blindness, and 59 (12.5%) from uniocular blindness. CONCLUSIONS: In a hospital population in Tunisia, the most common causes of uveitis were Behçet's disease, herpes simplex infection, toxoplasmosis, and VKH disease.
