Уважаемый Hematolog!
Пожалуйста, не нужно заочно, через сеть делать умозаключения, когда Вы не видели ни результатов анализов, ни (тем более) обладаете большим опытом в диф.диагностике тромбоцитозов. Это может нанести непоправимый урон в степень доверия между пациентом и реальным врачом: "не навреди, если не можешь помочь".
Кратко: существуют и не клональные тромбоцитемии, диагноз тромбоцитемии ставится после тщательного исключения всевозможных причин реактивного тромбоцитоза, ни один клинический признак или лаб. или цитогенетический анализ не способен с высокой точностью отдифференцировать эти 2 состояния.

Thrombocytosis.
Schafer AI.
Reactive thrombocytosis is driven by elevated endogenous levels of thrombopoietin, interleukin-6, other cytokines, or catecholamines that may be produced in inflammatory, infectious, or neoplastic conditions or in situations of stress.
Rare cases of familial thrombocytosis were initially described as an autosomal dominant disorder in which gain-of-function mutations in the thrombopoietin gene lead to overproduction of thrombopoietin and marked elevation of its plasma levels.
Essential thrombocythemia is one of the chronic myeloproliferative disorders, a group of related disorders of the hematopoietic stem cells. Recent studies have suggested that essential thrombocythemia may not always be clonal. These findings raise the possibility that a nonclonal disease can progress to clonal disease, that clonality is restricted in some patients to the megakaryocytic lineage, or that essential thrombocythemia is a heterogeneous disorder. Because of substantial pitfalls in the interpretation of clonality assays, these tests are not yet clinically applicable for diagnostic purposes.
Essential thrombocythemia remains largely a diagnosis of exclusion of secondary (reactive) causes of thrombocytosis. There are presently no diagnostic findings that can definitively distinguish between clonal and secondary (reactive) thrombocytosis. Laboratory tests likewise do not offer clear-cut distinctions. Therefore, bone marrow examination is a useful ancillary test for clonal thrombocytosis, albeit a nondiagnostic one.
