Abstract
INTRODUCTION Hairy cell leukemia (HCL) is a rare lymphoproliferative disorder of the mature B-cells, mostly seen in men, and is characterized by cytopenia, splenomegaly, myelofibrosis, and the presence of atypical lymphoid cells showing the cytoplasmic hairy projection in the peripheral blood, bone marrow, and spleen. The immunophenotypic (IPT) profile shows the clonal expansion of B-cells with CD19, CD20, and CD22 showing bright expression. The diagnosis requires two hairy cell markers out of CD103, CD123, CD25, and CD11c to be positive. The HCL variant (HCL-v) has a different IPT profile with negative CD25 in most cases. AIM The aim was to study the hematological and IPT of classical HCL and HCL variants. METHODS This cross-sectional study included all the cases of HCL diagnosed over a retrospective period of eight years from 1st January 2015 to 31st December 2022 in a tertiary care hospital in north India. The patients included in the study were those for whom immunophenotyping; that is, flow cytometry and/or immunohistochemistry (IHC) were done for diagnosis. Bone marrow slides, IHC slides, and flow cytometric IPTs were reviewed. RESULTS The study included 13 patients who were diagnosed to have HCL, of which 12 were classical HCL and one was HCL-variant (HCL-v). Among classical HCL, IPT was done by flow cytometry in 10 patients, while in two patients, it was done by IHC. CD19, CD20, and CD22 were positive in all patients of classical HCL (10/10, 10/10, and 5/5, respectively), while CD123, CD103, CD25, and CD11C were positive in 100%, 89%, 80%, and 100% cases, respectively. One patient of HCL-v had CD103 and CD123 positive, while CD25 and CD123 were negative. CONCLUSION The diagnosis of HCL requires a multipronged approach. The use of clinical features, morphology, and immunophenotyping combined with ancillary techniques provides higher diagnostic accuracy and enables its distinction from other B-cell lymphoproliferative disorders (BCLPDs), leading to better patient management and treatment.

Abstract
There have been several case reports associating hairy cell leukemia (HCL) with non-Hodgkin’s lymphoma. However, it remains unclear whether these rare phenomena represent disease transformation or the coexistence of two separate disease entities. De novo marginal zone lymphoma can be routinely seen in elderly patients; however, in a patient with a history of HCL, a transformation is more likely than de novo blastoid marginal zone lymphoma. In this report, we present a rare case of a patient with HCL developing a high-grade blastoid marginal zone B-cell lymphoma (MZBCL).

Abstract
Hairy cell leukemia (HCL) is a rare chronic B-cell lymphoproliferative disease which is treated on the basis of small studies, making the literature still scarce of reports, especially of those conducted in Latin America. Here we intend to describe clinical characteristics, rates of response, survival and second neoplasms in HCL patients treated in a reference center in Brazil. All patients diagnosed with HCL between July/1987 and Jun/2018 were included in this analysis. Fifty-four patients were included in this analysis. Median age at diagnosis was 55 years (range, 26-88), with 37% being above 60 years-old. Most patients were treated with cladribine in our cohort (n = 36; 68%), administered through intravenous continuous infusion. Remaining patients were firstly managed with splenectomy (n = 7; 13%), IFN (n = 6; 11%) and rituximab (n = 2; 4%). In a univariate analysis, platelet count and B2M level at diagnosis were statistically associated with CR achievement (p = 0.004 and p = 0.024, respectively). A median follow-up time of 9 years was calculated. Estimated 10-year overall survival was 91.1% (95% confidence interval, 77-97). In this cohort, 10 patients had any second neoplasm, diagnosed before or after HCL. Regarding the sites of cancer, 69% were of skin - 8/16 carcinoma-type and 3/16 melanoma-type. Our response and survival data are similar to those reported by literature, which reaffirms the role of purine analogs in current HCL management. With a very long follow-up we also have observed a high incidence of second neoplasm.

Abstract
Oral hairy leukoplakia (OHL) is an oral mucosal lesion that is associated with Epstein-Barr virus infection. It commonly presents as an asymptomatic, non-removable white patch on the lateral borders of the tongue in individuals who are immunocompromised. Historically, OHL was thought to be pathognomonic of HIV infection; however, it is now an established phenomenon in a range of conditions affecting immune competence. Hairy cell leukaemia (HCL) is a rare chronic B cell lymphoproliferative disease named after the distinctive cytology of the atypical cells. We report the first case of OHL arising in an individual with HCL that resolved following remission of the haematological malignancy.

Abstract
The description of hairy cell leukemia as a specific clinical entity was published 50 years ago. The clinical outcome for patients was hampered by ineffective chemotherapy, and splenectomy was the major therapeutic approach to improve peripheral blood counts. The median survival after diagnosis was 4 years. With the introduction of alpha-interferon in 1984, marked improvements in patient responses were observed. Shortly thereafter, the introduction of the purine nucleoside analogs transformed this disease into a highly treatable form of leukemia, and patients with the classic form of this rare leukemia now have a near-normal life expectancy. However, other clinical entities mimicking this disease do not respond; thus, accurate diagnosis is important. Immunophenotypic features in classic hairy cell leukemia show that the leukemic cells express CD11c, CD25, CD103, and CD123 and display bright CD20. Despite the high percentage of durable complete remissions with modern therapy, the long-term disease-free survival curves have not reached a plateau. Many patients who achieve a complete remission by morphologic criteria have minimal residual disease demonstrable by either flow cytometry or immunohistochemical staining, and this population may be at higher risk for earlier relapse. Continued clinical research is essential to optimize therapy for this disease.
