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.
