Introduction: Cutaneous lymphomas (CLs) represent the clonal proliferation of neoplastic T or B lymphocytes and rarely of natural killer (NK cells) or plasmacytoid dendritic cells the diagnosis and classification of PCLs should always be based on a combination of clinical, histological, immunophenotypically and genetic. Treatment should be selected, taking into account the type of lymphoma and its stage and should be adapted to risk. Skin-directed therapies are the first choice for treating the early stages of the disease.
Case presentation: We present a case of cutaneous lymphoma on a 32-year-old woman. The diagnosis was established based on history, physical examination, histopathology, and immunohistochemistry (IHC) examination, which showed CD20 negative and CD3 negative. Patients were treated with an emollient and topical corticosteroid, as the results of the hyperpigmented plaques lesions regressed, and the patients are symptom-free at regular follow up 6-month later.
Conclusion: Topical corticosteroids can be used to treat refractory cases in early-stage disease. An important point in the diagnosis and classification of Primary Cutaneous Lymphoma (PCL) is based on a combination of clinical data and histopathological.
Cutaneous Lymphoma; Cutaneous T-Cell Lymphoma; Cutaneous B-Cell Lymphoma
Lymphomas are a several group of malignancies that cover many different histological categories. Cutaneous lymphomas (CLs) are a proliferation of neoplastic T or B lymphocytes and rarely from natural killer cells (NK) . There are two types of cutaneous lymphoma (CL), namely primary skin lymphoma (PCL) and secondary skin lymphoma, due to systemic lymphoma (SCL). Primary cutaneous lymphoma is diagnosed when there is cutaneous involvement, without evidence of lymphoproliferative disease at another location at the time of diagnosis [2,3]. Primary cutaneous lymphoma of B-cell (CBCL) and T-cell (CTCL) is a heterogeneous group of non-Hodgkin’s lymphoma (NHL) . Cutaneous lymphoma is classified based on variations in clinical manifestations, histopathology, immune phenotyping, and genetic examination . Here we report this rare a cutaneous lymphoma where immunohistochemical examination results showed negative CD20 and negative CD3.
