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

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 in which leukemic cells invade the skin before they appear in peripheral blood or bone marrow specimens. The condition frequently is misdiagnosed as atypical lymphoma. Generally, the diagnosis is made retrospectively, after the leukemic cells appear in peripheral blood or bone marrow samples. Immunohistochemical studies are the primary methods for diagnosis. Prognosis is usually poor. We describe the case of a 75-year-old woman with acute aleukemic monocytic leukemia cutis who developed systemic disease 1 1/2 years after skin involvement. 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

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

Leclercia adecarboxylata is a rare, gram-negative rod that has been infrequently reported in the literature. The organism has been documented to cause solitary infections in immunocompromised hosts and polymicrobial wound infections in the immunocompetent. We present a case of an 8-year-old boy with significant past medical history of acute lymphoblastic leukemia who developed cellulitis due to local infection by L. adecarboxylata. This case is presented to raise awareness of this rare organism's ability to cause common cutaneous disease, especially in the immunocompromised. 相似文献

INTRODUCTION: We report the case of a Pseudomonas (P.) aeruginosa eccrine hidradenitis in a child, or a "Pseudomonas Hot Foot Syndrome", revealing an acute lymphoblastic leukemia. OBSERVATION: A 10 year-old girl consulted for the sudden onset of painful and necrotic palmoplantar nodules in a context of fever and shivering. Histology of a cutaneous biopsy found necrosis of the eccrine glands and, on culture, P. aeruginosa. The blood count revealed pancytopenia and the myelogram acute lymphoblastic leukemia. All the hemocultures and other microbiological samples were negative. The cutaneous signs had appeared 48 hours after bathing in an aquatic amusement park. Diagnosis of Pseudomonas eccrine hidradenitis, or "Pseudomonas Hot Foot Syndrome" was retained, although the local sanitary authorities were not able to demonstrate P. aeruginosa contamination of the water in the park. COMMENTS: Lesions evoking juvenile Pseudomonas aeruginosa eccrine hidradenitis without obvious traumatic factor must lead to the search for P. aeruginosa contamination from water and the subsequent sanitary and epidemiological consequences. Furthermore, severe P. aeruginosa cutaneous infections in children must also lead to the search for an underlying immunosuppression and notably an acute leukemic process. 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

The hypereosinophilic syndrome (HES) is defined by a longer than 6-month history of peripheral blood hypereosinophilia (greater than 1.5 x 10(9)/L), with signs and symptoms of internal organ involvement, in the absence of an identifiable cause. HES is therefore a diagnosis of exclusion. Patients have been reported who initially met the criteria for HES but subsequently developed a rare hematologic malignancy known as acute lymphoblastic leukemia with eosinophilia (ALL-Eo). We report such a case in a 10-year-old boy who presented to the pediatric dermatology clinic with unusual, urticarial skin lesions. Although skin involvement is often reported in cases of HES and ALL-Eo, such findings are variable and reports in the dermatology literature are few. We emphasize the importance of continuous monitoring for underlying malignancy in children with urticarial skin lesions in the setting of unexplained hypereosinophilia. 相似文献

We report a child with a T-cell lymphoblastic lymphoma, and a widespread erosive mucocutaneous eruption, whose clinical and immunopathological features were consistent with a diagnosis of paraneoplastic pemphigus. Direct immunofluorescence showed deposition of C3 in the epidermal intercellular spaces, and in a linear pattern along the dermo-epidermal junction. Circulating autoantibodies binding in a pemphigus-like pattern to mouse urinary bladder epithelium were found. By Western immunobiotting, the patient's serum recognized two epidermal polypeptides with molecular weights of 210 and 190 kDa. No reactivity with the 230-kDa bullous pemphigoid antigen and the 250-kDa desmoplakin I antigen was found. 相似文献

Concurrent chronic lymphocytic leukemia cutis and acute myelogenous leukemia cutis in a patient with untreated CLL 总被引:1,自引:0,他引:1

Patients who have chronic lymphocytic leukemia (CLL) are known to have a high frequency of second malignant neoplasms. However, acute myelogenous leukemia (AML) occurring concurrent with or after a diagnosis of CLL is extremely rare. In this article we report a case of AML developing in a 55-year-old male with a 6-year history of untreated CLL. The diagnosis was facilitated by touch preparation of a skin punch biopsy specimen. The patient presented with a two-week history of fever, weakness, anasarca, and a skin rash. Physical examination revealed pink to skin-colored firm papules, which coalesced into indurated plaques on his trunk, upper extremities, and face. The lesions, in combination with generalized edema, produced a leonine facies. Touch prep of the biopsy showed medium to large blasts, large monocytoid cells, and numerous small mature lymphocytes, providing the preliminary diagnosis of a second, previously undiagnosed myelomonocytic malignancy in this patient. The initial diagnosis was subsequently confirmed by histologic, cytochemical, immunohistochemical and flow cytometry studies. This is the first reported case of CLL with concurrent AML in which rapid touch prep of a skin punch biopsy facilitated diagnosis. 相似文献

Histologically proven leukemia cutis carries a poor prognosis in acute nonlymphocytic leukemia 总被引:1,自引:0,他引:1

A retrospective study of fifty-eight patients with acute nonlymphocytic leukemia was undertaken to determine the incidence of leukemia cutis and whether skin involvement serves as a prognostic indicator. A clinical diagnosis of leukemia cutis was made in eleven patients (19 percent), and five patients (8.6 percent) had biopsy-confirmed skin involvement. Patients with biopsy-proven leukemia cutis had a median postdiagnosis survival of only 12.5 weeks compared with fifty weeks for the group without skin involvement. We conclude that leukemia cutis is a biopsy diagnosis that occurs in a minimum of 8.6 percent of patients with acute nonlymphocytic leukemia in whom survival appears to be shortened. 相似文献
