Twenty-six cases of adult T-cell leukemia/lymphoma (ATLL) were identified between 1983 and 1991 in Martinique (French West Indies). There were 14 men and 12 women, all of mixed racial descent and born in Martinique. Their ages ranged from 23 to 95 years. The main clinical and laboratory features at initial presentation were peripheral lymphadenopathy (22 cases), hepatomegaly (11 cases), splenomegaly (10 cases), cutaneous lesions (12 cases), hypercalcemia (16 cases), refractory infection by Strongyloides stercoralis (12 cases), and pre-existing autoimmune disorders (4 cases). All patients had absolute lymphocytosis with circulating pleomorphic abnormal lymphocytes. The prognosis was poor, with most patients (20 cases) surviving for less than 6 months. Although the overall clinicopathologic features of ATLL in this series are similar to those described in previous reports, we observed three additional points of interest: a high association with Strongyloides infection, an increased incidence of tropical spastic paresis/HTLV-1 associated myelopathy (TSP/HAM) among the relatives of the patients (5 cases), and the presence of prior collagen vascular diseases.

Human T-lymphotropic virus type I (HTLV-I) is the etiologic agent of HTLV-I associated myelopathy (HAM)/tropical spastic paresis (TSP), and adult T-cell leukemia/lymphoma (ATLL). ATLL has been associated with HTLV-I in the southeastern United States. However, to our knowledge, no case reports of HAM/TSP in association with ATLL occurring in the United States have been described. We describe a 40-year-old black woman with a 10-year history of recalcitrant psoriasiform eruption and erythrodermic flares. Medical history is additionally significant for a 2-year history of HTLV-I-associated myelopathy and lower extremity spastic paresis. Polymerase chain reaction with Southern blot analysis was used to detect HTLV-I proviral genome from frozen skin biopsy specimens and peripheral blood mononuclear cells.

Human T-cell lymphotropic virus type I (HTLV-I)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) has been associated with changes in extracellular matrix of neural tissue. HTLV-I infection has multiple other systemic effects. Extracellular matrix is important for bone mineral deposition. We examined bone mineral density (BMD) in patients with HAM/TSP. BMD was assessed by ultrasonographic calcaneous densitometry in 24 patients (7 males, 17 females) with HAM/TPS, and 23 healthy HTLV-I-seronegative controls matched by age and sex. Patients with HAM/TPS had a mean BMD T-score of -3.07 +/- 0.64 in males and -2.93 +/- 0.69 in females. Control patients revealed a T-score of -0.77 +/- 1.31 in males and -1.17 +/- 1.08 females. The difference in T-score between HAM/TSP patients and control groups is significant (P < 0.001). Of HAM/TPS patients, 7 of 24 (29.2%) had osteopenia (T-score between -1 and -2.5) and 17 of 24 (70.8%) were diagnosed with osteoporosis (T < -2.5). Respective figures for control patients were 10 of 23 (43.5%) with a normal T-score, 11 of 23 (47.8%) with osteopenia, and 2 of 23 (8.7%) with osteoporosis. After adjustment for age and sex, odds ratio of osteoporosis for HAM/TSP patients was 31.52 (95% confidence interval, 5.07 to 195.88). No correlation was found in HAM/TSP patients between T-score and age, menstrual status, gait functionality, or years of evolution of HAM/TSP. HAM/TSP patients have a significantly diminished BMD of the calcaneous that appears not to be explained by paresis, age, years of disease, menstrual status; may be the result of systemic alterations due to HTLV-1 infection.

Human T-cell lymphotropic virus (HTLV) types 1 and 2 belong to the Oncorna group of retroviridae, a large family of viruses, grouped initially by pathogenic features, but later revised on the basis of genome structure and nucleotide sequence. HTLV-I was the first discovered human retrovirus to be associated with a malignancy in 1980. The malignancy, first described by Uchiyama and co-workers in southwestern Japan, was named Adult T-cell Leukemia/Lymphoma (ATL) and characterized with cutaneous and respiratory involvement, hepatosplenomegaly, lymphadenopathy and various metabolic abnormalities such as hypercalcemia. The HTLV-I has been known to be endemic to certain parts of Iran like the province of Khorasan in the northeast since 1990, with a 2.3% prevalence rate of infection. The main manifestations of HTLV-I infection are neurologic and hematologic (such as ATL) disorders, but it has also other manifestations such as uveitis, arthritis, dermatitis, vitiligo and lymphocytic alveolitis. Its main neurologic manifestation is a chronic progressive myelopathy that is referred to HTLV-I Associated Myelopathy (HAM) in Japan and Tropical Spastic Paraparesis (TSP) in Caribbean. But other disorders such as peripheral neuropathy, polyradiculoneuropathy, myopathy, peripheral facial paresis, and so on have been reported too. In this review we wish to give some brief information on the different aspects (including epidemiology, pathogenesis and pathology, clinical findings, and treatment) of HTLV-I infection according to our twenty-year researches. The department of neurology of Mashhad University of Medical Sciences has been a pioneer in researches on HTLV-I in the last twenty years.
