INTRODUCTION: Cutaneous syringotropic T-cell lymphoma is a rare form of lymphoma. We report a case involving a misleading cutaneous presentation on the sole of the foot.
PATIENTS AND METHODS: A 55-year-old woman presented discrete coalescent papules on her left foot, having an anhidrotic appearance, for which a number of antifungal treatments had been given without success. The skin biopsy revealed CD4+ T lymphocytic dermal infiltrate, mainly near the sweat glands, with syringotropism. The diagnosis of syringotropic T-cell lymphoma was reinforced by the presence of dominant cutaneous T-lymphocyte clone in the skin biopsy. Staging tests were negative. Treatment was initiated with an extremely potent (class IV) dermal corticosteroid.
DISCUSSION: Syringotropic T-cell lymphoma is an extremely rare form of cutaneous lymphoma similar in presentation to mycosis fungoides, characterised by the mainly perisudoral and syringotropic nature of the lymphocytic infiltrate. The value of this case report lies in the extremely mild nature of the misleading skin lesions, which could only be diagnosed through biopsy. Treatment for this condition is not as yet codified due to the extremely low number of cases reported in the literature.
