[Interdigitating dendritic cell sarcoma-a case report with literature review].
ABSTRACT OBJECTIVE: To report a case of interdigitating dendritic cell sarcoma (IDCS). PATIENT MATERIAL: The patient was a 41-year-old man with a lymph node bulging in the left neck. Laboratory examination of peripheral blood and bone marrow was abnormal. The diagnosis of IDCS was made by immunohistochemistry and electron microscopy. Treatment of this patient with ABVD regimen (adriamycin, bleomycin, vinblastine, dacarbazine) resulted in obvious improvement, but did not control the tumor infiltration. CONCLUSION: IDCS has no distinctive clinical or pathohistological characteristics. Immunohistochemistry and electron microscopy are crucial in distinguishing it from other histiocytic/dendritic cell neoplasms. IDCS displays an aggressive behaviour, and the responses to chemotherapy are variable.

ABSTRACT: Interdigitating and follicular dendritic cell sarcoma (DCS) are very rare diseases, with approximately 184 cases being reported thus far, and their best treatment modality is still on debate. This is a review of all the cases of dendritic cell sarcoma reported from 1981 until April 2006. This review is enriched with the original contribution of five cases occurred at our Institution from 1994 to 2006. The review of the literature pointed out that radical surgery alone was curative in approximately two thirds of these cases, the relapsing rate in patients who received adjuvant treatments being higher than 30%. We pinpoint new five cases of dendritic cell sarcoma (three FDCS and two IDCS). Both the analytic revision of the literature and our data suggest that localized DCS may be effectively treated by radical surgery and do not support the use of adjuvant treatments after radical excision.Critical Reviews in Oncology/Hematology 02/2008; 65(1):1-7.

ABSTRACT: To evaluate the importance of inter-institutional second opinion surgical pathology review of lymphoma, and identify the lymphoma pathologic mimics. The surgical pathology material of patients referred to 2 tertiary care hospitals in the western region of Saudi Arabia (King Faisal Specialist Hospital and Research Centre and King Abdulaziz University Hospital, Jeddah, Saudi Arabia), for evaluation or therapy for lymphoma over a 10-year period (August 2001 to August 2011), were reviewed. This study included only cases in which the patient referred with a diagnosis previously made at the primary institution. Of 560 cases, the second opinion diagnosis differed significantly from the initial diagnosis in 39 cases (7%). These include changing the diagnoses from lymphoma to non-lymphoma lesions, change the type of lymphoma with major clinical impact, and change from reactive/non-diagnostic to lymphoma. Second opinion surgical pathology for lymphomas can result in major therapeutic and prognostic modifications. Thus, review of the original histologic material is recommended prior to a major therapeutic decision, and to maximize the discovery of clinically relevant major disagreements. Stringent adherence to institution's second opinion policy is an important quality assurance measure in surgical pathology.Saudi medical journal 04/2012; 33(4):399-405. · 0.55 Impact Factor
