Introduction: Natural killer/T-cell lymphoma, nasal type is a distinct entity, rarely reported in sub-Saharan Africans. Although the skin is the second most common involved site after the nasal cavity, very few cases of primary cutaneous extranodal natural killer/T-cell lymphoma (PC-ENK/T-NT) have been reported so far. Their clinical features reported in the literature are variable.
Case report: We report a case of a 48-year-old man with a PC-ENK/T-NT presenting as a multinodular and ulcerated tumor of 9 cm in diameter on his left leg, mimicking a large B-cell lymphoma, leg type at the onset and only developed nasal and lymph node involvement at a later stage.
Conclusion: PC-ENK/T-NT in our case is remarkable by its presentation simulating a B-cell lymphoma of leg type.
