Aleukemic leukemia cutis has always been a dermatological curiosity. It is a rare condition characterized by the infiltration of skin by leukemic cells before their appearance in the peripheral blood or bone marrow. A 20 year old man had presented with nodular swelling on the scalp of 6 months duration along with cervical lymphadenopathy. Biopsy and immunohistochemistry revealed myeloid sarcoma. The initial presentation was aleukemic and repeated peripheral blood counts and marrow examinations were normal. However, the outcome was fatal within 3 months of diagnosis of cutaneous lesions. 相似文献

Aleukemic leukemia cutis 总被引:1,自引:0,他引:1

A 46-year-old man presented with nodular skin lesions, a biopsy specimen of which demonstrated a poorly differentiated malignancy. Touch preparations with histochemical staining and electron microscopy confirmed leukemia cutis. Results from a bone marrow aspirate disclosed focal areas of increased myeloblasts, and cytogenetic analysis revealed an abnormal karyotype as follows 46,XY, t(1;2) (q44p13). Antileukemic therapy resulted in prompt disappearance of the skin nodules, and a return of the patient's bone marrow to normal was noted, but after six months of intensive chemotherapy leukemia cutis recurred without morphologically identifiable leukemia in the bone marrow. The patient underwent successful bone marrow transplantation from an HLA-identical sibling but died 70 days after the transplant from disseminated aspergillosis. 相似文献

Specific leukemic cutaneous infiltrates preceded observable leukemic cells in the blood in a case of acute lymphoblastic leukemia. Examination of a cutaneous biopsy specimen led to early diagnosis of the disease. 相似文献

A newborn girl had typical "blueberry muffin" skin lesions, which showed histopathologic features of myelomonocytic leukemia cutis. We could not demonstrate leukemic infiltration of bone marrow in four aspirates. Her course was complicated with primary pulmonary hypertension, which led to death at 7 months of age. We emphasize the persistence of skin lesions in the absence of bone marrow infiltration by leukemia throughout the course of the disease. 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 8-year-old boy presented with a widespread cutaneous eruption featuring macules, papules, nodules, and ulcers. The histologic infiltrate showed T lymphoblasts, but there was no sign of systemic involvement, so aleukemic leukemia cutis was diagnosed. Two months later, he developed leukemia in peripheral blood and bone marrow that was characterized as T-cell acute lymphoblastic leukemia. 相似文献

A patient with acute myelomonocytic leukemia is reported. He had presented erythroderma and atypical cellular infiltration of the skin 4 months prior to the detection of leukemia in the peripheral blood and bone marrow. Aleukemic leukemia cutis is a rare condition which is characterized by leukemic cells invading the skin prior to the observation of leukemic cells in the peripheral blood. The cases of aleukemic leukemia cutis reported in the literature show little or no conformity in their clinical appearance. Enzyme cytochemistry, immunocytological and electron-microscopic studies are of considerable help in differentiating the cutaneous infiltrates and in establishing early diagnosis. We report herein a patient with erythroderma which regressed spontaneously, whereas microscopic examination of a cutaneous biopsy showed atypical cells infiltrating the dermis. After a period of 3 months, during which the patient remained free of lesions, he showed recurrence of the erythroderma while developing acute myelomonocytic leukemia. We feel this unusual presentation of aleukemic leukemia cutis should be added to the evergrowing list of cutaneous manifestations of leukemia. 相似文献

We report a 3 1/2-year-old girl who developed a figurate cutaneous eruption. Distinctive findings in her skin biopsies, as well as unusual red cell characteristics, in the presence of a normal peripheral smear and bone marrow biopsy, led us to suspect the diagnosis of preleukemic juvenile type chronic granulocytic leukemia. This is the first case we know of in which this diagnosis was suspected prior to abnormal findings in the peripheral smear or bone marrow. 相似文献

A 67‐year‐old woman was referred to our department with a 1‐month history of facial exanthemas. She had been diagnosed as having acute monocytic leukemia (French–American–British classification, M5b) based on the histological findings of bone marrow. Physical examination revealed diffuse edematous erythema on her cheeks, eyelids and glabella with scattered reddish papules. Histological examination demonstrated dense infiltration of atypical mononuclear cells in the dermis. Specific cutaneous lesions could occur in acute monocytic leukemia more frequently than in other types of leukemia, but rarely show symmetrical edematous erythema limited to the face. 相似文献

Abstract: We describe a premature neonate who was born with pancytopenia and a single subcutaneous nodule on her right lower extremity. A biopsy specimen from the nodule demonstrated a dense infiltrate of pleomorphic mononuclear cells that extended throughout the dermis and into the subcutaneous tissue. Immunohistochemical stains and bone marrow examination confirmed a diagnosis of acute myelogenous leukemia. Cytogenetic studies on peripheral blood by G-banding analysis revealed an abnormal karyotype of 46, XX, ins[inv(10)(p11.2q22.2);11](q22.2;q13.2q23.2). A split in the mixed lineage leukemia gene was identified by fluorescence in situ hybridization. Induction chemotherapy was started but was complicated by multiorgan failure. The patient died on the eleventh day of life. As leukemia cutis more typically presents as multiple infiltrative papules, nodules, or plaques, we stress the importance of including leukemia in the differential diagnosis of a solitary nodule in a neonate. 相似文献

We present a 6-year-old girl with an 8-month history of fluctuating chilblain-like lesions on the toes. A full blood count showed slight thrombocytopenia and monocytosis. A skin biopsy specimen showed a dense perivascular and superficial dermal cellular infiltrate which was CD3(-), CD43(+), and lysosyme + on immunocytochemistry, suggesting a monocytic origin. Juvenile myelomonocytic leukemia was diagnosed after a bone marrow biopsy and spontaneous marrow colony growth in culture. 相似文献

We report an unusual case of congenital leukemia with leukemia cutis (LC) and diffuse calcinosis cutis. A newborn girl presented with widespread dusky red and yellowish cutaneous nodules and papules. Bone marrow morphology was consistent with the diagnosis of acute monocytic leukemia of the FAB M5 type. Skin biopsy specimens confirmed the presence of a leukemic infiltrate and revealed calcium salt deposition in the papillary and reticular dermis. Calcinosis was diffuse in the whole skin but spared other organs. Vascular calcification was not present. Serum calcium levels oscillated between 2.5 and 2.86 mmol/l, and phosphorus, parathyroid hormone and 25-hydroxyvitamin D(3) levels were normal. There were diffuse osteoporosis and spontaneous fractures of small tubular bones. The patient responded to chemotherapy but, following consolidation treatment, developed sepsis and died at 120 days of age. Congenital leukemia is rare and LC is uncommon. Hypercalcemia may be a complication of leukemia, which leads to multiorgan metastatic calcification. Despite the absence of frank hypercalcemia, the presence of bone lesions suggests that the patient's calcinosis cutis was of the metastatic type. However, the cutaneous leukemic infiltrate may also represent a triggering factor for calcium deposition in the skin. 相似文献

Congenital poikiloderma is an uncommon hereditary disorder. It has been reported in association with various syndrome. No case has previously been reported from this environment. We report a case of congenital poikiloderma in a two and a half year old female Nigerian associated with unusual generalised hypopigmentation and acral blisters at birth. The child subsequently developed macular hyperpigmentation on an erythematous background and atrophy of the skin. Although she had some features which were suggestive of Rothmund-Thomson syndrome (RTS), the presence of hypopigmentation at birth, along with acral blistering, was noted to be peculiar to this child. We, therefore, feel that this case presents a distinct variant of congenital poikiloderma that has not been described previously. 相似文献
