Follicular Dendritic Cell Sarcoma Presenting as a Submucosal Tumor of the Stomach

Abstract Follicular dendritic cell (FDC) sarcomas, especially those of extranodal origin, are extremely rare, and this entity could easily be missed without a high index of suspicion. We report a case of FDC sarcoma presenting as a submucosal tumor of the stomach in a 45-year-old man. The mass was a spindle and epithelioid mesenchymal tumor with many individually scattered and perivascular aggregates of lymphocytes. Immunohistochemical and ultrastructural studies confirmed the diagnosis. Although more than 50 cases of this tumor have been documented in the English literature, to our knowledge the presentation of FDC sarcoma as a submucosal tumor of the stomach has never been recorded. This case highlights the occurrence of FDC sarcoma as a submucosal tumor of the gastrointestinal tract. We believe that FDC sarcoma should be included in the differential diagnosis of spindle or epithelioid cell tumors of the gastrointestinal hollow viscus to prevent this still underrecognized tumor from being overlooked.

Abstract Background: Inflammatory Pseudo Tumor (IPT)-like Follicular Dendritic Cell (FDC) Sarcoma of the liver is a very rare disease and occurs mostly in the lymph nodes. Till now, only 19 cases were reported in the English literature. However, the coexistence of IPT-like Sarcoma and Non-Hodgkin’s Lymphoma(NHL) in the same patient has never been reported.Case presentation: We reported a case of a 47-year-old male patient who had a history of Hepatitis B virus (HBV) infection and presented with right upper abdominal discomfort. Nineteen years ago, he underwent liver resection of segment VII for Hepatic Non-Hodgkin Lymphoma (B-cell lymphoma). Serum alpha fetoprotein (AFP) level was normal. However, Imaging studies revealed a well-circumscribed, solid mass in the right hepatic lobe and was diagnosed as (Hepatocellular Carcinoma) HCC or Hepatic Lymphoma preoperatively. Right hemi-hepatectomy was performed on this patient. Histological report showed features of a mixture of chronic inﬂammatory cells and variable amounts of spindle cells. Also, Immuno-Histo-Chemical (IHC) studies demonstrated that all the tumor cells showed strong nuclear in situ labeling for EBV-encoded small RNAs (EBER) and strongly positive stainings with CD21 and CD35. The patient is still disease free after a follow-up of 40 months. Conclusions: To our knowledge, this is the first report demonstrating Hepatic IPT-like FDC Sarcoma in a patient with Primary Hepatic Non-Hodgkin Lymphoma history. In regards to treatment, complete surgical resection should be performed and would acquire excellent long-term outcomes.

Thyroid follicular dendritic cell sarcoma (FDCS) is an extremely rare malignancy that originates from follicular dendritic cells of the thyroid germinal centers. To the best of our knowledge, there are only 4 reported cases of thyroid FDCS in the English literature. Herein, we present the fifth case of FDCS of the thyroid gland. A 63-year-old woman presented with a painless midline neck mass, enlarging for the last 4 months. Physical examination revealed a 6-cm nonmobile, firm, multinodular thyroid mass with palpable cervical lymphadenopathy. Due to high suspicion for thyroid malignancy, the patient underwent total thyroidectomy with bilateral modified radical neck dissection. Histologic evaluations revealed sheets of storiform eosinophilic tumoral cells with prominent nucleoli containing multinucleated giant cells, and subsequent immunohistochemistry showed immunoreactivity for CD4, CD21, CD35, CD45 (LCA), and CD68. The patient was started on 6 cycles of doxorubicin, ifosfamide, and radiotherapy. She has had monthly thyroid ultrasonography and contrast-enhanced thoracoabdominal CT scan every 3 months for detecting potential recurrence and/or metastasis screening. Fortunately, 8 months after the operation, the patient is alive without any signs of local or distant metastasis.
