Dyskeratosis congenita (DC) is a hereditary syndrome of bone marrow failure, which develops because of telomeres defects and combines with cancer predisposition. Its classical clinical features are skin pigmentation, nail dystrophy, oral leukoplakia (skin-mucosa triad). The goal is to describe the algorithm of diagnosis, clinical specificities of DC and specific treatment for cases of DC in one family. ⋯ The report underlines an importance of diagnosis of all family members for excluding an asymptomatic form after a case of DC has been already detected in that family. A high frequency of a toxicity and secondary neoplasia makes it necessary to realize an individual approach at treatment of each patient with DC (the earliest start of androgen treatment, prompt decision of implementation of allogenic hematopoietic stem cell transplantation). The knowledge of pathogenesis, clinical features and principles of diagnosis and therapy of this disease is relevant to pediatricians and hematologists.

LiFraumeni syndrome (LFS) is a rare, autosomal dominant, hereditary disorder that is characterized by an increased risk for certain types of cancer, acute lymphoblastic leukemia (ALL), particularly. Germline TP53 mutations are associated with LFS. Genetic counseling and follow-up is essential for patients with LFS and their relatives. Special therapeutic approaches are needed for treatment of oncological disease in these patients. The article presents a series of clinical cases of patients with ALL and SLF, considers general issues of diagnosis and treatment of adult patients with this hereditary genetic syndrome. ⋯ Practical value of the research is the observation that the greater part of TP53 gene mutations in patients with Ph-negative B-cell ALL are germinal and associated with LFS.

Mantle cell lymphoma (MCL) is a rare and clinically aggressive lymphoma subtype. Current approaches have greatly improved patients outcomes, but relapse is inevitable. In phase IIIII clinical trials, ibrutinib has shown significant activity in patients with relapsed or refractory (R/R) MCL. ⋯ Ibrutinib is effective and well tolerated in routine practice of R/R MCL treatment and our results are consistent with international clinical trials. The favorable toxicity profile and the high response rate made it possible to prescribe ibrutinib in severe somatic status, cytopenia, and even in the presence of infectious complications.

Thrombotic complications are the most significant factors determining the prognosis in myeloproliferative neoplasms. Markers for assessing the risk of thrombosis are the number of leukocytes, platelets, hemoglobin level, hematocrit, age, molecular status, history of thrombosis, obesity, arterial hypertension, hyperlipidemia, hereditary or acquired thrombophilia. The pathogenesis of thrombosis in patients with myeloproliferative neoplasms is complex and multifactorial. ⋯ Currently, antiplatelet and anticoagulant therapy is carried out on an individual basis. The algorithm for primary and secondary (after thrombosis) prevention requires development and testing. We present a clinical case of repeated arterial and venous thrombotic complications in a patient with primary myelofibrosis.

The prevalence of multiple primary tumors has significantly increased last time. The question of choosing the optimal tactics of therapy today not fully resolved. ⋯ This publication presents a case of simultaneous diagnosis of myeloid sarcoma and mantle cell lymphoma in a 65-year-old patient, which required use of two different chemotherapy protocols. This example shows the need to use an extended diagnostic approach at all stages of the therapy, which allows choosing right tactics of therapy and achieving complete remission of two neoplasms.
