Follicular eruption with folliculotropic lymphocytic infiltrates associated with anti-tumor necrosis factor alpha therapy: Report and study of 3 cases.

Follicular eruptions with folliculotropic lymphocytic infiltrates associated with anti-TNF-α therapy may show some immunophenotypical variations and/or monoclonal TCR gene rearrangements but lack sufficient cytomorphological features of folliculotropic MF. They may resolve with discontinuation of anti-TNF-α therapy.
