Analysis of proliferative lesions of haematopoietic and lymphoid tissue in the female productive tract / 中华妇产科杂志

ABSTRACT

Objective To study the clinicopathologic features,diagnosis and differential diagnosis of tumors of haematopoietic and lymphoid tissue in the female productive tract. Methods Eleven cases of myeloid sarcoma and leukemia, 9 of non Hodgkin lymphoma(NHL),13 of cervical lymphoma-like lesions were selected from Peking University People′s Hospital from January 2006 to August 2017. According to WHO classification of tumors of haematopoietic and lymphoid tissues(2008)and updated classification(2016),the cases were studied by microscopy,immunohistochemistry and in situ hybridization.Results In 20 cases of tumors of haematopoietic and lymphoid tissue,the mean and median age was 48.5 and 56 years old(range16-77 years old).In cases of lymphoma-like lesion of uterine cervix,the mean and median age was 45.9 and 48 years old(range23-62 years old).The patients with neoplasm present as fever,fatigue, hypogastralgia, colporrhagia and mass etc. Eight cases had history of acute myeloid leukemia, and 3 had myeloid leukemia while pregnancy. One case of chronic lymphocytic leukaemia/small lymphocytic lymphoma(CLL/SLL)had history of ovary small cell carcinoma and high grade serous carcinoma resected with chemotherapy.One case of diffuse large B cell lymphoma(DLBCL)had history of renal transplantation. Lactic dehydrogenase(LDH)was elevated in 9 cases(9/18).The cases of lymphoma-like lesion present as contact bleeding in most cases and all located in cervix. Four cases of neoplasm located in vulva, 1 in vagina,4 in cervix, 4 in uterine corpus, 8 in ovary and 2 in placenta.Clinical staging of NHL 4 case was stageⅠ,1 case of stageⅢ,and 4 cases of stageⅣ.Pathological morphology9 cases were myeloid sarcoma, 2 cases were placenta invaded by myeloid leukemia. Six cases were DLBCL, and 1 case was CLL/SLL, 1 case was mucosa associated lymphoid tissuse lymphoma(MALToma), and 1 case was anaplastic large cell lymphoma. Resected mass, chemotherapy was performed in tumors of haematopoietic and lymphoid tissue. Five cases of myeloid sarcoma and 2 of NHL died. In 13 cases of lymphoma-like lesion of uterine cervix, the general condition was good as following up. Conclusions The clinical history, pathological morphology and immunohistochemistry are very important for diagnosing tumors of haematopoietic and lymphoid tissue in the female productive tract.Resection with chemotherapy is recommended in treatment. The prognosis of lymphoma-like lesion of uterine cervix is good,and should be differentiated from lymphoma.
