Interdigitating dendritic cell sarcoma (IDCS) is a rare tumour; only seven cases of IDCS associated with chronic lymphocytic leucaemia/small lymphocytic lymphoma (CLL/SLL) have been reported. We present the case of a 60-year-old man who presented with fevers, night sweats and significant unintentional weight loss. Investigations led to a diagnosis of synchronous SLL and IDCS. Subsequent fluorodeoxyglucose (FDG) positron emission tomography CT (PET-CT) imaging revealed an unusual clinical course with spontaneously resolving highly metabolic lesions. After 42 months of follow-up, the patient remains free of clinical symptoms and evidence of IDCS.
交错突细胞肉瘤（IDCS）是一种罕见肿瘤；仅有7例IDCS与慢性淋巴细胞白血病/小淋巴细胞淋巴瘤（CLL/SLL）相关的病例报道。我们报告一例60岁男性患者，其表现为发热、盗汗及明显的非故意体重减轻。检查诊断为同步性SLL和IDCS。随后的氟脱氧葡萄糖（FDG）正电子发射断层扫描CT（PET-CT）成像显示了一个不寻常的临床过程，即高代谢病灶自发消退。经过42个月的随访，患者仍无临床症状及IDCS证据。
