【Abstract】0bjecfive To analyze the clinicopathological features of acute monocytic leukemia cuffs.
Methods A retrospective study was performed on four patients with acute monocytic leukemia with skin lesions as
the initial presentation.Results All the patients were elderly people with the age being 68,70,74 and 82 years
respectively.Typical cutaneous lesions were multiple,reddish or purple,tenacious papules,plaques,or nodules
involving the trunk and extremities.There was no obvious subjective symptom.Histopathologically,there was a dense
and diffuse infiltration of numerous monomorphous tumor cells in the dermis。which were medium—sized.kidney—or
oval—shaped with obvious atypia and arranged concentrically around blood vessels or appendages or linearly between
collagen fibers.An uninvolved zone of papillary dermis that separated the normal epidermis from the underlying
dermal infiltrate was observed.Immunohistochemical analysis showed that the tumor cells were positive for CD68.
CD4,CD45RO,CD56,leukocyte common antigen(LCA),but negative for CD3,CD20,CD30,CD34,CDl 17 and
CDl23.Conclusions Acute monocytic leukemia cuffs mainly occurs in elderly people.which iS pathologically
characterized by a dense monomorphous infihration of tumor cells between collagen fibers throughout the dermis as
well as an uninvolred zone between the dermis and epidermis.

(acute myeloid leukemia,AML)占2%一20%L“。而AML—FAB
分级亚型中M4和M5亚型患者伴发LC E”的比率最高,可达
到50%。现总结本院皮肤科门诊就诊的4例以皮肤浸润首发
的AML—M5一LC患者的临床资料,以探讨该病特点并分析早
期诊断相关因素。
一、临床特点
患者均为老年人,年龄分别为68、70、74、82岁,平均年
龄73.5岁。2例女性,2例男性。皮疹多见于躯干和四肢,常泛
发全身,表现为质韧的大小不一的充实性丘疹、结节、斑块,
绿豆至蚕豆大小。皮损颜色为淡红色至紫色,偶有暗红色及
棕色,无明显自觉症状。见图l。
二、实验室检查
发病早期血常规及骨穿检查正常。多在皮损出现后1个
