One of the main subjects of discussion in mycosis fungoides is the relationship with the so-called “parapsoriases”. Lymph nodes, lung, spleen and liver are the most frequent sites of extracutaneous involvement in mycosis fungoides, but specific lesions can arise in all organs. Mycosis fungoides can be observed in association with other hematological diseases such as lymphomatoid papulosis, anaplastic large cell lymphoma, and Hodgkin lymphoma. Scoring systems and algorithms for the diagnosis of mycosis fungoides have been proposed, combining the clinical aspect with the immunophenotypic and molecular features of the infiltrate. Epidermotropism of solitary lymphocytes is usually found, but Darier's nests (Pautrier's microabscesses) are rare. Molecular analysis of early lesions of mycosis fungoides is hindered by the intrinsic difficulties in the identification of neoplastic cells, which are a small minority and may look morphologically and phenotypically identical to reactive lymphocytes.
