Abstract:
Objective:To study clinicopathologic features, prognosis and differential diagnoses of primary mucosal CD30-positive T-cell lymphoproliferative disorders of the head and neck(mCD30+ TLPD-head and neck).
Methods:Three cases of mCD30+ TLPD-head and neck were collected from January 2014 to April 2017 at Sun Yat-Sen University Foshan Hospital. A literature review of mCD30+ TLPD of head and neck was provided.
Results:All three cases presented with either bulging/exophytic nodule or mucosal ulcer/erosion. Morphologically, the tumor consisted of diffuse proliferation of uniform, large atypical mononuclear lymphoid cells that showed irregular or polymorphic nuclei with small nucleoli, and abundant pale or amphophilic cytoplasm. Hallmark cells with eccentric, horseshoe, kidney-like, or doughnut-shaped nuclei were present. While mitotic figures were present, no tumor necrosis was found. Eosinophilc infiltration was obvious in the background. The atypical large lymphoid cells had a immunophenotype of CD30+ /CD3+ /CD4+ /CD56- along with positive cytotoxic molecule. While being negative for EBER/ALK/CD20/CD8, TCR rearrangement was found in 2 out of 3 cases. Three patients were cured after excision without relapse and metastasis.The two patients with TCR rearrangement didn′t show aggressive clinical course.
Conclusions:mCD30+ TLPD-head and neck is a rare benign lymphoproliferative disorder with spontaneous regression. It should be differentiated from cutaneous CD30+ anaplstic large cell lymphoma, lymphomatoid papulosis, and EBV-related mucocutaneous ulcer. Correct recognition of mCD30+ TLPD of head and neck is important to avoid overtreatment.
