Flow Cytometry as a Diagnostic Tool in the Early Diagnosis of Aggressive Lymphomas Mimicking Life-Threatening Infection

Aggressive lymphomas can present with symptoms mimicking life-threatening infection. Flow cytometry (FC) is usually recommended for the classification and staging of lymphomas in patients with organomegaly and atypical cells in effusions and blood, after the exclusion of other possible diagnoses. FC may also have a place in the initial diagnostic investigation of aggressive lymphoma. Three cases are presented here of highly aggressive lymphomas in young adults, which presented with the clinical picture of fever of unknown origin (FUO) in patients severely ill. All followed a life-threatening clinical course, and two developed the hemophagocytic syndrome (HPS), but microbiological, immunological, and morphological evaluation and immunohistochemistry (IHC) failed to substantiate an early diagnosis. FC was the technique that provided conclusive diagnostic evidence of lymphoma, subsequently verified by IHC. Our experience with these three cases highlights the potential role of FC as an adjunct methodology in the initial assessment of possible highly aggressive lymphoma presenting with the signs and symptoms of life-threatening infection, although the definitive diagnosis should be established by biopsy. In such cases, FC can contribute to the diagnosis of lymphoma, independently of the presence of HPS

Primary lymphoma of the spermatic cord: A case report and review of the literature

Primary lymphomas of the spermatic cord are extremely rare. To date, only 15 cases have been reported in the international literature. Herein, we report a new case of a primary lymphoma of the spermatic cord. A 73-year-old patient presented at the Urology Department, complaining of bilateral painful masses at the inguino-scrotal region. A computed tomography scan revealed spermatic cord tumor. A right inguinal orchidectomy was performed in order to establish a definitive diagnosis. Macroscopically, the tumor was restricted to the spermatic cord area, leaving unaffected the testis and the epididymis. The histopathological and immune-histological evaluation has indicated a diffuse large B-cell lymphoma. Postoperatively, the patient was investigated thoroughly but no further signs of the disease were found
