DefinitionThis section has been translated automatically.
Very rare, primary T-cell lymphoma of the skin, in which the tumor cells by definition exhibit the phenotype of cytotoxic T-cell with expression of CD3 and CD8 (see below for an overview of lymphoma, cutaneous T-cell lymphoma, cytotoxic). CD8+ CTCL is characterized by its own clinical and immunohistological characteristics and a well defined aggressive course.

HistologyThis section has been translated automatically.
Histology: Predominantly image as in mycosis fungoides or pagetoid reticulosis with band-shaped, diffuse infiltrate of small, medium or large immunoblastic pleomorphic, distinctly epidermotropic T cells. The epidermis is acanthotic with different, but mostly very dense lymphocytic infiltrates.

Differential diagnosisThis section has been translated automatically.
- Cutaneous T-cell lymphomas of other origins (see below lymphoma, cutaneous T-cell lymphoma).
- Mycosis fungoides: Clinically varied and variable picture (time interval from first symptoms to diagnosis: 4.2 years!). Skin symptoms develop very slowly (months to years). Systemic involvement is only detectable after a longer clinical course. Typical clinical course of lymphoma in 3 stages.
Pagetoid reticulosis "disseminated type" (Ketron and Goodman): Especially in older men, disseminated, reddened, rapidly growing, scaly plaques and nodules. Tendency to generalization.
Notice! These are probably T-cell lymphomas which must be classified as CD8+ cutaneous T-cell lymphomas.
