Abstract Background Inflammatory pseudotumor-like follicular dendritic cell sarcoma is a rare histological variant of follicular dendritic cell sarcoma involving typically the spleen and the liver, often linked to the presence of Epstein–Barr virus infection. Definite diagnosis of this type of sarcoma is difficult to make owing to nonspecific clinical and imaging findings and is based on histopathological features. Inflammatory pseudotumor-like follicular dendritic cell sarcoma is described as a low-aggressivity tumor with a favorable prognosis. Case presentation We report the case of a 34-year-old Caucasian woman, Epstein–Barr virus positive, diagnosed with hepatic inflammatory pseudotumor-like follicular dendritic cell sarcoma and surgically treated in November 2014, who developed 6 years later a recurrence for which she underwent once again surgical treatment. As far as we know, fewer than 30 reports of inflammatory pseudotumor-like follicular dendritic cell liver tumors have been reported in the English literature. Conclusions Although it is an uncommon tumor, inflammatory pseudotumor-like sarcoma is a diagnostic worth being taken in consideration, and surveillance is recommended owing to the possibility of recurrence.

Abstract Follicular dendritic cell sarcoma of the liver is an uncommon pathologic entity, and only 5 cases have been reported previously. Herein, we report the first case, to our knowledge, of hepatic follicular dendritic cell sarcoma without evidence of Epstein-Barr virus infection. The patient is an elderly man who was found to have an incidental liver mass and then developed weight loss and fever. The diagnosis was based on the typical morphologic appearance of spindle cell proliferation associated with a brisk lymphoplasmacytic infiltrate and strong immunoreactivity to CD21 and CD35. Based on our experience and a review of the published reports, we summarize the clinical and pathologic features of hepatic follicular dendritic cell sarcoma and its surgical management.

Abstract BACKGROUND: Follicular dendritic cell (FDC) sarcoma is a neoplastic proliferation of spindled to ovoid cells showing morphological and immunophenotypic features of FDCs. Inflammatory pseudotumor-like follicular dendritic cell sarcoma(IPT-FDCS)involves almost exclusively in the liver and spleen and are consistently associated with Epstein-Barr virus (EBV).Rarely, it selectively involves the gastrointestinal tract in the form of a polypoid lesion.CASE SUMMARY: We report two cases of IPT-FDCS mimicking a colonic polyp that received high frequency electrocoagulation separately.The patients’main concern were whether to have chemotherapy or radiation after removal.After many consultations and literature review,The patients were treated by surgical resection, without adjuvant chemotherapy or radiation. Follow-up for 32 months showed no recurrence or metastasis.RESULTS: The neoplasms usually had well—defined borders,composed of the neoplastic spindled cells are dispersed within a prominent lymphoplasmacytic infiltrate. The nuclei usually show a vesicular chromatin pattern and small but distinct nucleoli. Immunohistochemically,tumor cells showed the expression of at least one of the FDC markers,including CD21,CD35, CD23 and D2-40,with scattered positive EBER in situ hybridization.CONCLUSION: IPT-FDCS could rarelly occur in the intestine with a polypoid appearance. Recognization of this disease could avoid being misdiagnosed as other common types of colonic polyposis. EBV-encoded mRNA (EBER) by in situ hybridization and FDC-related immunohistochemical markers plays an important role in differential diagnosis.
