ABSTRACT
Mycosis fungoides (MF) is characterized by epidermotropic atypical lymphocytes infiltrate with α/ß T-helper memory immunophenotype (ßF1+, CD3+, CD4+, CD45Ro+, and CD8-). Angiocentricity is always associated with aggressive behavior or poor outcome in primary or secondary cutaneous lymphomas. Rare cases of angiocentric MF with a T-cytotoxic immunophenotype (CD3+, CD4-, CD8+, TIA-1+) have been described. Here, we report a 27-year-old man diagnosed with MF, clinically presenting with ichthyosiform lesions on his trunk and limbs. Biopsy demonstrated a CD3+ and CD8+ atypical lymphocytic infiltrate with marked epidermotropism and angiocentricity. Awareness of this rare MF variant with unusual clinicopathological characteristics is important to avoid misdiagnosis.
