[T-cell lymphoma/leukemia secondary to HTLV-1 in adults. Report of a case].

The Human T-Cell lymphotropic virus type I (HTLV-I) is endemic in the Caribbean basin, Japan, Central Africa and South Pacific. It as been associated to Lymphoma-Leukemia of Adult T-Cells (ATLL) and a progressive spastic paraparesis (TSP/HAM). The nationwide seroprevalence of Panama is of 1-2%. We report a case of a 73 year old male, albino, single, patient, Panamanian descendent from Jamaican immigrants who presented a skin disorder which started 1 year ago, characterized by the appearance of infiltrative, intensely pruritic papules, nodules and a non exfoliative erythroderna involving face, neck, trunk and extremities. He also had painless enlarged cervical lymph nodes, non tender hepatomegaly. Laboratory studies revealed a keukocyte count of 128,000/ml wit 67% atypical lymphocytes, serum calcium was 12.5 mg/dl, DL in 583 UNI, "flower cells" and atypical lymphocytes with hyperlobulated nuclear contour was observed in the peripheral blood smear, seropositivity to TLV-I detected by enzyme-linked immunosorbent assay (Elisa) and confirmed by Western blot assay. The skin biopsy shows a bandlike dermal infiltrates of atypical lymphoid cells with epidermotropism and Pautrier's microabscesses. Once the treatment was initiated with prednisone, cyclophosphamide, and systemic antibiotics for a bronchopneumonic process most of the cutaneous lesions cleared up although the clinical condition of our patient became progressively worse and died after a acute renal failure and a lower gastrointestinal bleeding. In 1986, the tree first cases of ATLL were identified in Panama, there has not been apparently new cases reported until now.
