To understand the clinicopathological and molecular genetic characteristics of aggressive renal mucinous tubular and spindle cell carcinoma (MTSCC). The clinical features, histology, immunophenotype, molecular characteristics and prognosis of 4 cases of metastatic/recurrent renal MTSCC that were submitted to the Peking University Third Hospital (2 cases), Institute of Urology, Peking University (one case) and Zhejiang Provincial People's Hospital (one case) from 2015 to 2020 were retrospectively reviewed and analyzed. Among the four patients, two were male and two were female.

Lymphomas of T-follicular helper origin (T-follicular helper-cell lymphoma [TFHL]) are often accompanied by an expansion of B-immunoblasts, occasionally with Hodgkin/Reed-Sternberg-like (HRS-like) cells, making the differential diagnosis with classic Hodgkin lymphoma (CHL) difficult. We compared the morphologic, immunophenotypic, and molecular features of 15 TFHL and 12 CHL samples and discussed 4 challenging cases of uncertain diagnosis. Compared with CHL, TFHL disclosed more frequent sparing of subcortical sinuses, high-endothelium venule proliferation, dendritic cell meshwork expansion, T-cell atypia, and aberrant T-cell immunophenotype.

PGTL can present with a variety of gastrointestinal symptoms, but patients only rarely present with perforation.

Atypical polypoid adenomyoma (APA) is a benign uterine lesion with a premalignant potential and occurs in women of reproductive age. The histological pattern is characterized by irregular epithelial proliferation and muscular stroma. Based on a case report, we performed a systematic review of the literature to assess the main immunohistochemical and molecular markers that contribute to its differential diagnosis against endometrial adenocarcinoma (EC).

Introduction: Primary bone marrow diffuse large B-cell lymphoma is a rare clinical entity, and the "bone marrow-liver-spleen" type of diffuse large B-cell lymphoma is rarer, with only a few published cases in literature. Though bone marrow-liver-spleen-type diffuse large B-cell lymphoma has unique presentations such as fever, cytopenias, and hemophagocytic lymphohistiocytosis, no cases with cold autoimmune hemolytic anemia have been reported.
Case Presentation: A 39-year-old Sri Lankan woman, previously healthy, presented with shortness of breath, productive cough, and fever for 4 days.
