Methods
Routine blood investigations revealed normal findings. Skin biopsy showed epidermotropism, Pautrier’s microabscesses and perivascular lymphocytic infiltrates (Figure 2 a, b). Immunohistochemistry revealed intraepidermal and perivascular atypical cells which were immunopositive for CD2, CD3, CD4, CD5 with Ki-67 proliferation index of 20% and negative for CD20. Bone marrow aspiration and bone marrow biopsy performed were normal. CT scan reports of the neck, chest, abdomen and pelvis were normal. Based on clinical, histopathological and immunohistochemistry findings, the patient was diagnosed as case of Mycosis fungoides, a subtype of primary cutaneous T cell Non-Hodgkin Lymphoma.
