1/13. Orbital and facial granulocytic sarcoma (chloroma): a case report.Granulocytic sarcoma is an uncommon manifestation of myelogenous leukemias in which focal masses of immature myeloid cells from the granulocytic lineage infiltrate bone and soft tissue. It is most common in the pediatric population and may present at any time in the course of the disease, either concurrently with the onset of leukemia or during a remission or relapse. Occasionally, it may precede the clinical onset of acute myelogenous leukemia (AML), presenting a diagnostic challenge.- - - - - - - - - - ranking = 1keywords = leukemia (Clic here for more details about this article) |
2/13. head and neck granulocytic sarcoma with acute myeloid leukemia: three rare cases.We conducted a retrospective review of pathology files and hospital records and identified three unusual presentations of granulocytic sarcoma associated with acute myeloid leukemia (AML) of the head and neck. At least one mass was observed on the skin of all three patients. A 17-year-old boy had masses in each temporal region that were accompanied by bilateral facial paralysis. He was administered chemotherapy and radiotherapy, but he died of infection secondary to a second relapse 29 months after the initial diagnosis. A 17-year-old girl had a tumor in the right parotid area. She received chemotherapy, but she died of infection and bleeding 2 months after the initial diagnosis. A 33-year-old man had numerous tumors widely disseminated over his skin. He received chemotherapy and was in remission 12 months after the initial diagnosis, but he eventually relapsed and died. Granulocytic sarcoma can be localized in unexpected regions, including the head and neck. This tumor is very often misdiagnosed as a malignant lymphoma, which leads to delayed treatment and a poor outcome. Therefore, clinical and histopathologic findings should be evaluated before any diagnosis of malignant lymphoma is pronounced. Immunohistochemical stains should also be performed on patients with suspected granulocytic sarcoma, and aggressive chemotherapy or immunotherapy should be administered. We believe that high-dose chemotherapy can improve survival rates in granulocytic sarcoma associated with AML.- - - - - - - - - - ranking = 1.6666666666667keywords = leukemia (Clic here for more details about this article) |
3/13. Reconstruction of a complex hemifacial deformity with multiple simultaneous free-flap transfers: case report.Severe disfigurement, facial paralysis, abnormal continuity of oral and nasal passages, and velopharyngeal incompetence resulted, following maxillectomy and cranial-base resection for a radiation-induced sarcoma. Oral lining, bone support, facial muscle, and outer skin were provided with a single-staged transfer of radial forearm, scapular bone, scapular skin, and serratus anterior muscle with anastamoses to the contralateral neck. This combination of flaps may be considered in complex facial deformities, and may obviate the need for staged prefabrication.- - - - - - - - - - ranking = 9.3703387201946keywords = radiation-induced (Clic here for more details about this article) |
4/13. Squamous cutaneous epithelial cell carcinoma in two CML patients with progressive disease under imatinib treatment.Imatinib (glivec), formerly known as STI571) effectively blocks the ATP-binding site of the bcr/abl fusion protein thereby inactivating selectively the tyrosine kinase activity of bcr/abl. Therefore, it is a promising drug in philadelphia chromosome positive chronic myeloid leukemia showing high hematologic and cytogenetic response rates combined with a mild toxicity profile. Here we report two cases of squamous cell carcinoma of the skin, which appeared in the photo-exposed areas in two elderly patients treated for advanced chronic myeloid leukemia with imatinib. The role of chemotherapy, chronic sun exposure and of possible additional risk factors such as human papillomavirus infection is discussed.- - - - - - - - - - ranking = 0.66666666666667keywords = leukemia (Clic here for more details about this article) |
5/13. A diagnosis of chronic lymphocytic leukemia prompted by cutaneous lymphocytic infiltrates present in mohs micrographic surgery frozen sections.BACKGROUND: Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in the united states. patients with CLL are at an increased risk for the development of second malignant neoplasms, the most common of which is cuta-neous squamous cell carcinoma (SCC). Cutaneous infiltrates of CLL have been reported in association with primary cutaneous neoplasms, including SCC, basal cell carcinoma, and actinic keratosis. The finding of a dense lymphocytic infiltrate surrounding a cutaneous neoplasm should prompt consideration of possible underlying CLL. OBJECTIVE: To review the relationship of CLL to cutaneous SCC and to raise awareness of the possible coexistence of these two neoplasms. methods: The case report describes a patient with a SCC of the left cheek treated with Mohs micrographic surgery. A dense lymphocytic infiltrate was noted on the frozen sections, and a complete blood count was obtained. RESULTS: A lymphocytosis was detected, leading to the diagnosis of CLL, stage 0. CONCLUSION: patients with CLL are at an increased risk for the development of cutaneous neoplasms. An infiltrate of leukemic cells in documented CLL patients can be associated with cutaneous neoplasms such as SCC. We present a patient with no known hematologic malignancy who demonstrated a dense lymphocytic infiltrate on Mohs sections. The diagnosis of CLL was considered based on the appearance of this infiltrate. Subsequently, a new case of CLL was confirmed with appropriate testing. The finding of a dense subcutaneous infiltrate of lymphocytes on Mohs frozen sections should raise the possibility of CLL and lead to appropriate screening tests.- - - - - - - - - - ranking = 2keywords = leukemia (Clic here for more details about this article) |
6/13. Unusual skin lesions in chronic myelomonocytic leukemia.Chronic myelomonocytic leukemia (CMML) is a relatively rare, heterogeneous syndrome classified as a myelodysplastic syndrome according to the French-American-British classification system. The patient's presenting symptom was a pigmented skin nodule that, although common for cases of acute monoblastic leukemia, is peculiar for CMML. This case should increase awareness of the inclusion of CMML in the differential diagnosis of a discolored nodule and highlight the clinicopathologic considerations and therapeutic challenges consistent with the diagnosis of CMML.- - - - - - - - - - ranking = 2keywords = leukemia (Clic here for more details about this article) |
7/13. Evidence for an association between hairy cell leukemia and renal cell and colorectal carcinoma.BACKGROUND. Hairy cell leukemia (HCL) has been associated with several disease states. In this study, a possible association is reported between HCL and renal cell carcinoma (RCC) and colorectal carcinoma (CRC). methods. A retrospective study of the case records of 50 patients with HCL in a study of alpha-interferon (alpha-IFN) treatment of HCL. RESULTS. Three of 50 patients with HCL studied had RCC, and 2 of these also had CRC. In addition, two other patients had CRC. The other malignant lesions developed either before or after the diagnosis of HCL. In all patients, the HCL responded to alpha-interferon (alpha-IFN), but in four patients, the second lesion was diagnosed during IFN treatment. CONCLUSIONS. These findings could indicate that IFN does not correct a possible common basic etiologic defect and shows that even early CRC and RCC do not respond to the IFN doses administered. These findings should be considered in future trials of IFN treatment of these diseases. The authors also recommend a reevaluation of the frequency of second malignant lesions in HCL; this may be important particularly with the increased survival in patients with HCL who receive alpha-IFN treatment.- - - - - - - - - - ranking = 1.6666666666667keywords = leukemia (Clic here for more details about this article) |
8/13. The first case of li-fraumeni syndrome in Bosnia and Herzegovina: case report.li-fraumeni syndrome (LFS) is a very rare autosomal dominant and highly penetrant cancer syndrome characterized by early-onset primary tumours, including soft tissue and bone sarcoma, breast cancer, leukemia, brain tumours and adrenocortical carcinoma. Here we report the first evidence-based case of LFS in Bosnia and Herzegovina and the whole Balkan region. A ten year-old girl developed multiple primary tumours (rhabdomyosarcoma) during a period of eight years, as well as fibroadenoma of the breast. Sequential analysis revealed a germ line mutation of TP53 in exon 8, a common mutation in patients with LFS, in both the patient and her mother.- - - - - - - - - - ranking = 0.33333333333333keywords = leukemia (Clic here for more details about this article) |
9/13. The occurrence of leukemia in a patient with pulmonary asbestosis.A 77-year-old man, who had been a subway construction worker, was admitted to our hospital for surgical treatment of left cheek carcinoma and an examination for pancytopenia on November 17, 1986. bone marrow aspiration revealed that 10% of the nucleated cells were blasts with morphological atypism. bone marrow biopsy showed hypocellular marrow and a diffuse increase of argyrophil fibers with the presence of asbestos fibers was observed by microscope. A chest X-ray showed the findings of old tuberculosis and pulmonary asbestosis, and asbestos fibers were demonstrated in the broncho-pulmonary lavage fluid. He was diagnosed to have pulmonary asbestosis complicated with hypoplastic low percentage leukemia.- - - - - - - - - - ranking = 1.6666666666667keywords = leukemia (Clic here for more details about this article) |
10/13. Facial reconstruction for radiation-induced skin cancer.radiation-induced skin cancers can be difficult to diagnose and treat. Typically, a patient who has received orthovoltage radiotherapy for disorders such as acne, eczema, tinea capitis, skin tuberculosis, and skin cancer can expect that aggressive skin cancers and chronic radiodermatitis may develop subsequently. Cryptic facial cancers can lead to metastases and death. Prophylactic widefield excision of previously irradiated facial skin that has been subject to multiple recurrent skin cancers is suggested as a method of deterring future cutaneous malignancy and metastases. The use of tissue expanders and full-thickness skin grafts offers an expedient and successful method of subsequent reconstruction.- - - - - - - - - - ranking = 37.481354880778keywords = radiation-induced (Clic here for more details about this article) |
