Lymphocytoma cutis (Spiegler-Fendt Sarcoid)


假性淋巴瘤成因很多,包括局部刺激(針灸、穿耳洞、紋身、蚊蟲叮咬、局部感染、疫苗接種)、藥物(phenytoin),但多數原因難以確定。此疾病似乎西方人較多,女性為主(3:1),年紀一般小於40歲。


診斷是靠病理,臨床外觀上最大特色是浸潤性非脫皮丘疹,紅色、棕色、紅紫色或是膚色都有。典型B細胞為主者,多為局部病灶(佔有70%),好發於臉部及上肢,散發型多見於年紀較長者,發於軀幹及四肢。


治療上並無定論,一般而言類固醇(口服、外用、注射)、放射線治療、PUVA、冷凍、hydroxychloroquine、干擾素注射、imiquimod (T cell type)、光動力治療、rituximab都可能有效,如果是感染相關者,則也可以嘗試先治療感染症(borreliosis)。若不治療,疾病病程不定,經過長期追蹤也有少數轉變成淋巴瘤(主要是primary cutaneous marginal zone B-cell lymphoma,但也有large B-cell lymphoma),但不到10%,在一篇研究中,經過的時間是 17-51 months
