Skin lesion of extranodal natural killer/T-cell lymphoma nasal type.

We report herein the case of an 81-year-old female patient who presented with poor feeding, various skin lesions, and pancytopenia. She finally received the diagnosis of extranodal natural killer/T-cell lymphoma nasal type (ENKTL-NT) without nasal lesions after four skin biopsies. Skin lesions of ENKTL-NT are usually nonspecific, making diagnosis based on cutaneous findings alone difficult. Hence, repeated biopsies, not only of the lesion, but also of the surrounding, normal tissue, are needed especially when the skin lesions are of uncertain etiology or intractable and accompanied by systematic symptoms or pancytopenia.
