Leukemia, Hairy Cell*

Hairy cell leukemia (HCL) is a rare, chronic, mature B-cell lymphoproliferative disorder accounting for 2% of all leukemias. In this paper, we would like to present our experience in the management of HCL in a financially limited setting where other diagnostic tests and chemotherapy are unavailable. The case report aims to emphasize the recognition of the distinctive morphology of hairy cells in the peripheral blood in the consideration of the initial diagnosis. A 60-year-old Filipino male was incidentally found to have anemia, thrombocytopenia and an absolute neutrophilic count below 1,000 in a pre-operative clearance for elective herniorrhaphy. Blood smear revealed atypical lymphocytes with hair like cytoplasmic projections. CT-scan of the abdomen showed splenomegaly and prominent paraaortic nodes. Flow cytometry of the bone marrow aspirate was consistent with an involvement of a Mature B cell neoplasm markers CD19, CD20, CD22 and surface immunoglobulin lambda and hairy cell leukemia markers CD11c, CD103 and CD25. He responded to six-weekly sessions of Cladribine with remission of the bone marrow and hematologic parameters. HCL is a rare type of a mature B cell neoplasm characterized by pancytopenia, splenomegaly, bone marrow fibrosis and the presence of atypical lymphoid cells with hairy projections in blood, bone marrow and spleen. Immunophenotyping express CD11c, CD103, CD123, and CD25. BRAF V600E mutation is the disease defining genetic event. Cladribine and Pentostatin are the first line of treatment. Cases of leukemia can be easily overlooked because of the mild derangement in the complete blood count. A meticulous differential review of the atypical lymphocyte, is the first step in the diagnosis of this rare disease.

Leukemic reticuloendotheliosis (L.R.E.) was first described as a clinical and pathological entity by Ewald in 1923. LRE is a rare neoplastic disease of the hematopoietic system that is characterized cliniclly by chronic course with an insidious onset. marked splenomegaly with absence of substantial lymphadenopathy and predominant in male and characterized histologically by the presence of circulating abnormal mononuclear cells with many cytoplasmic projections, which have been refered to ??airy cells frequently. Splenectomy appeared to be the most beneficial treatment at present for those patients with massive splenomegaly and hypersplenism and chemotherapy is of little benefit in the treatment in LRE. Recently, the authors had the opportunity to observe a two year and eight old male child at this hospital whose clinical course and pathologid features were consistent with LRE. Splenectomy is performed and discharged with relatively good conditions.

BACKGOUND: Interferon-alpha2b has already proven to be effective in the clinical treatment of virus-originated diseases such as hairy cell leukemia, condyloma acuminatum, and AIDS-related Kaposi's sarcoma. The use of recombinant interferon-alpha2b may allow various types of wart to be treated relatively atraumatically and with less incidence of recurrence. OBJECTIVE: We tried to compare the effectiveness and safety of intralesional injections of recombinant interferon-alpha2b with natural interferon-alpha2b in the treatment of patients with various types of wart. METHOD: Patients with more than two warts were treated by injecting the different warts with 0.5 to 1.0X105 IU/1mm3 of recombinant and natural interferon-alpha2b, twice per week for 4 to 20 weeks. The response to treatment was followed up at 36 weeks. RESULTS: At the end of treatment, clearing of the treated warts had occurred in 83.3% of the recombinant interferon-alpha2b group and 91.6% of the natural interferon-alpha2b group. A more rapid cure rate was observed in the natural interferon-alpha2b group than in the recombinant interferon-alpha2b group. The rest showed partial improvement. With evaluation for relapse up to 16 weeks after treatment, warts were found to relapse in 11.1% of both the recombinant and natural interferon groups. CONCLUSION: Intralesional natural interferon-alpha2b has a better therapeutic effect than recombinant interferon-alpha2b, and may be considered as a therapeutic modality of recalcitrant verruca or when it can be anticipated that destructive techniques or blistering agents will not be tolerated.
