目的 探讨髓细胞性白血病皮肤浸润的临床表现、皮损组织病理及免疫组化特点.方法 分析6例髓细胞性白血病皮肤浸润患者的临床表现、皮损组织病理、免疫组化、实验室检查、治疗及转归.结果 6例中1例以皮肤白血病为首发表现,5例皮肤浸润出现于确诊白血病后的4 ~ 20个月.4例皮疹表现为泛发的红色浸润性丘疹、斑丘疹或结节,2例表现为局部肿物.组织病理示,真皮及皮下脂肪大量肿瘤细胞浸润,免疫组化髓过氧化物酶、CD43、CD45阳性率较高,其他出现阳性的标志物包括CD15、颗粒酶B、白细胞共同抗原、CD68.5例急性髓细胞性白血病均于出现皮肤浸润后60 d至1年内死亡.结论 髓细胞性白血病皮肤浸润一般发生于外周血象与骨髓象改变之后,偶尔也发生于白血病血象和骨髓象改变之前.皮疹常表现为结节或肿物,可局限可泛发,组织病理及免疫组化具有特征性.出现皮肤浸润者生存期短、预后差.  相似文献

2例患者均为急性白血病,其中1例无明显诱因双下肢皮肤出现红斑、结节,伴有疼痛,后自行消退遗留色素沉着,经检查诊断为急性白血病;另1例双足部皮肤出现红斑伴压痛,经检查诊断为急性单核细胞白血病。在临床看到不典型皮损伴有外周血异常(红细胞、白细胞、血红蛋白或血小板异常)时应考虑白血病皮肤表现的可能,需通过组织病理、骨髓涂片、骨髓病理和流式细胞学检查确诊,以免怠误病情。  相似文献

Aleukemic leukemia cutis is a rare condition in which patients have skin lesions containing leukemic cells before evidence of leukemia can be detected in the peripheral blood. There are only 23 cases of this phenomenon documented in the English literature. We describe a 62-year-old woman who developed a diffuse, clinically benign-appearing cutaneous eruption, which histologically showed an atypical infiltrate of cells, 4 months before leukemic cells were found in her peripheral blood and the diagnosis of acute myelomonocytic leukemia was made by bone marrow aspiration. This case illustrates the difficulty in diagnosing leukemia cutis from examination of routine histologic sections and the importance of specialized marker studies in determining the cause of an atypical cellular infiltrate of the skin. It also illustrates how leukemia cutis can masquerade as a clinically benign-appearing cutaneous eruption in a seemingly healthy patient with normal blood parameters.  相似文献

Aleukemic leukemia cutis is a rare condition characterized by the infiltration of the skin by leukemic cells before their appearance in the peripheral blood or bone marrow. We report here a 62-year-old seemingly healthy patient who presented with disseminated erythematous maculae. A skin biopsy showed leukemia cutis of monocytic type. No involvement of bone marrow or peripheral blood was found. The patient developed acute monocytic leukemia 7 months later. We present this case to illustrate how leukemia cutis can masquerade as a clinically benign-appearing cutaneous eruption without leukemic changes in blood or bone marrow. To confirm the diagnosis of aleukemic leukemia cutis, immunohistochemistry of the skin lesions as well as a complete staging procedure is necessary.  相似文献

An unusual case of leukemia cutis is presented. A 42-year-old man presented with a vesicular skin rash mimicking chickenpox. Skin biopsy firmly ruled out the diagnosis of varicella and revealed an infiltration of the superficial derma by myeloblasts. Bone marrow aspirates confirmed the diagnosis of acute myelomonocytic leukemia (type M4).  相似文献

Congenital leukemia is a rare disease that develops from birth to 6 weeks of life. Leukemia cutis involves cutaneous infiltration by leukemic cells and is an unusual manifestation of leukemia, and has been documented in 25~30% of patients with congenital leukemia. The authors report a case of congenital leukemia cutis. A newborn male presented with widespread firm dusky red papules and nodules on almost his entire body surface. Skin biopsy specimens confirmed the presence of leukemic infiltrations, and bone marrow cytology was consistent with acute myeloid leukemia of the FAB M5 type.  相似文献

Leukemia cutis is a specific skin lesion caused by infiltration of leukemic cells into the skin. It is uncommon in acute lymphocytic leukemia (ALL). It typically manifests as red or violaceous papules, nodules, or plaques, mainly on the face. Leukemia cutis presenting with a generalized viral exanthem-like maculopapular eruption appears to be rare in the English literature. We report such a case. A 19 year-old man presented with a generalized purpuric maculopapular eruption of eight day's duration. Hematologic studies showed changes of acute lymphocytic leukemia, T-cell type. A skin biopsy specimen revealed a cuff-like, dense, perivascular infiltration of atypical lymphocytes in the upper and mid-dermis, consistent with leukemia cutis. The rash resolved in two weeks after chemotherapy. Our case illustrates that leukemia cutis should be considered in the differential diagnosis of a generalized morbilliform viral exanthem-like eruptions. Skin biopsy is important in establishing the diagnosis.  相似文献

Cutaneous lesions of leukemia cutis (LC) by chronic neutrophilic leukemia (CNL) have been merely reported due to the rare occurrences of CNL. Furthermore cutaneous lesions in relation to clinical severity have been far less studied. A 70-year-old man presented with multiple violaceous papules and excoriations on both lower extremities. The diagnosis was LC based on histologic and laboratory evaluation and the origin was elaborated as CNL with the confirmation of colony stimulating factor 3 receptor (CSF3R) mutation. Interestingly, the patient presented clinical severity in a parallel manner to the hematologic abnormality. To the best of our knowledge, there has been no reported case of CSF3R confirmed LC in CNL featuring explicit skin eruption in relation to laboratory findings.  相似文献
