1/22. All-trans-retinoic acid-induced scrotal ulcerations in a patient with acute promyelocytic leukemia.Induction therapy with all-trans -retinoic acid has been shown to improve the outcome of patients with acute promyelocytic leukemia, although some side effects occur. Dry skin and lips are among the most common cutaneous side effects. We report a case of scrotal ulcerations induced by all-trans -retinoic acid in an American patient; to our knowledge this is the first such case reported.- - - - - - - - - - ranking = 1keywords = leukemia (Clic here for more details about this article) |
2/22. Case of radiation-induced esophageal ulcer worsened after endoscopic biopsy.Esophageal ulcer is one of the most important late complications of the esophagus treated with radiation therapy, especially with intraluminal brachytherapy. We encountered a patient with esophageal cancer treated with external radiation therapy and intraluminal brachytherapy, who developed radiation ulcer and who had severe dysphagia soon after endoscopic biopsy of the ulcer edge. A 55-year-old man was diagnosed as esophageal cancer without symptoms. He received 60 Gy/30 Fr of external radiation therapy and 12 Gy/3 Fr of intraluminal brachytherapy at a point of 5 mm in depth from the mucosa surface. He developed an asymptomatic esophageal ulcer 13 months after treatment, and endoscopic biopsy was obtained from the edge of the ulcer. Thereafter, swallowing difficulties appeared, and endoscopy revealed severe esophageal stenosis and a deep ulcer. A possibility that the biopsy contributed to worsening the ulcer can be considered. Except for cases where relapse is apparent, endoscopic biopsy is considered to be avoided.- - - - - - - - - - ranking = 22.675471493965keywords = radiation-induced (Clic here for more details about this article) |
3/22. Development of large genital ulcer due to hydroxyurea treatment in a patient with chronic myeloid leukemia and Behcet's disease.Chronic myeloid leukemia (CML) is a myeloproliferative disease arising from abnormal stem cells and associated with splenomegaly and leukocytosis. hydroxyurea and interferon alpha are used in treatment very frequently. Behcet's disease (BD) is a chronic, repetitive disease of unknown etiology and associated with mucocutaneous, ocular, vascular and central nervous system involvement. Cases with symptoms of BD have been reported during interferon alpha treatment of CML. However, similar symptoms due to hydroxyurea treatment have been reported in only one case until now. A 32-year-old female patient under follow up because of CML and BD, developed a large genital ulcer during hydroxyurea treatment. Ulcers due to hydroxyurea treatment and the co-existence of these two diseases has been reported in only one case in the literature while large genital ulcers have not been reported previously.- - - - - - - - - - ranking = 1keywords = leukemia (Clic here for more details about this article) |
4/22. Local injections of granulocyte-macrophage colony-stimulating factor (Gm-CSF) for the treatment of radiation-induced mucosa ulcers.We report two cases illustrating how Gm-CSF can facilitate rapid and persistent healing of ulcers associated with contact radiation therapy. This simple and safe method should be proposed for the treatment of chronic ulcers that develop in a formerly radiated zone.- - - - - - - - - - ranking = 22.675471493965keywords = radiation-induced (Clic here for more details about this article) |
5/22. Jejunal perforation associated with cytomegalovirus infection in a patient with adult T-cell leukemia-lymphoma.A patient with adult T-cell leukemia-lymphoma suffered a jejunal perforation, which we believe was directly attributable to cytomegalovirus (CMV) infection. In the areas of ulceration and perforation in the small bowel, blood vessels penetrating the muscularis propria showed extensive lining of cytomegalic endothelial cells with CMV inclusions, accompanied by occasional disruption of the walls, partial occlusion of the lumina, fibrin thrombi, and hemorrhage. The CMV-induced vascular damage seemed to be closely related to the occurrence of ulcers and perforation. The recognition of CMV as a cause of lethal gastrointestinal lesions in immunocompromised hosts has become more important with the advent of anti-CMV therapy.- - - - - - - - - - ranking = 1keywords = leukemia (Clic here for more details about this article) |
6/22. Genital ulcers during treatment with ALL-trans retinoic acid for acute promyelocytic leukemia.Scrotal ulcer is a unique adverse effect of all-trans retinoic acid (ATRA) in patients with acute promyelocytic leukemia (APL). The pathogenesis of scrotal ulceration remains unknown. We describe genital ulcers that developed in four patients with APL who were undergoing ATRA therapy (45 mg/m2 per day p.o.). Two of the patients were female, in whom this condition is quite rare. Genital ulcers with concomitant fever appeared between 17 and 32 days of therapy in all four patients. Genital ulcers healed in three of the patients while another patient developed Fournier's gangrene and underwent left testectomy. ulcer healing was brought by either local or intravenous corticosteroids. Intravenous dexamethasone actually enabled continued ATRA administration in one patient, while ATRA was discontinued in other two patients. If corticosteroids cannot control progression of genital ulcers nor concomitant fever, ATRA administration should be discontinued so as not to induce Fournier's gangrene nor retionic acid syndrome. Our experience indicates the importance of recognizing genital ulcers associated with ATRA in order that appropriate countermeasures can be taken.- - - - - - - - - - ranking = 1keywords = leukemia (Clic here for more details about this article) |
7/22. Scrotal ulceration during induction therapy of acute promyelocytic leukemia with ATRA.All-trans-Retinoic acid (ATRA) has been shown to improve survival in patients with acute promyelocytic leukemia (APML). It is a well-tolerated drug except for the serious side effect of ATRA syndrome. Dryness of the skin, cheilitis, and xerostomia are the common mucocutaneous side effects. Occurrence of scrotal ulceration is very rare. We report a 13-year-old boy who had scrotal ulceration caused by ATRA during the induction therapy of APML.- - - - - - - - - - ranking = 1keywords = leukemia (Clic here for more details about this article) |
8/22. mucous membrane pemphigoid in a patient with chronic lymphocytic leukemia.PURPOSE: To describe a case of mucous membrane pemphigoid (MMP) with ocular manifestations in a patient subsequently diagnosed with B-cell chronic lymphocytic leukemia (CLL). methods: Case report and literature review. RESULTS: A 64-year-old man presented with redness and irritation of both eyes. The patient also had blistering lesions on the roof of his mouth, trunk, and buttocks as well as bilateral conjunctival ulceration and symblepharon formation. A complete blood count performed before initiating treatment of presumed mucous membrane pemphigoid revealed a markedly increased white blood cell count (83,920) with a predominance of lymphocytes. Hematologic evaluation including immunophenotyping flow cytometry resulted in the diagnosis of B-cell chronic lymphocytic leukemia. cyclophosphamide treatment improved his MMP and decreased the white blood cell count. CONCLUSIONS: mucous membrane pemphigoid has been reported in association with a variety of nonhematologic malignancies. This case suggests that mucous membrane pemphigoid may also occur in B-cell CLL and supports the concept that autoantibodies play a role in the pathogenesis of this cicatricial conjunctival disease.- - - - - - - - - - ranking = 1.2keywords = leukemia (Clic here for more details about this article) |
9/22. Epstein-Barr virus-associated enteritis with multiple ulcers after stem cell transplantation: first histologically confirmed case.The present case involves unique enteritis forming multiple ulcers associated with Epstein-Barr virus (EBV). A 57-year-old man had undergone a reduced intensity allogeneic stem cell transplantation for a relapse of multiple myeloma following sequential autologous peripheral blood stem cell transplantation. The ileum, resected for massive melena, showed multiple irregular ulcers with occasional cobblestone-like appearance. There was inflammation including numerous plasma cells in the ulcer bases and surrounding areas, where many EBV-infected plasma cells were detected by double staining with EBV-encoded small rna-1 (EBER-1) in situ hybridization and CD79a, while EBV-infected epithelial cells were not noted. The number of EBER-1-positive cells in the ileum (mucosa, 1451 cells/mm(2); submucosa, 465 cells/mm(2)) was much larger than in control samples (malignant lymphoma or leukemia after allogeneic stem cell transplantation, n = 4, range 0-113 cells/mm(2); malignant lymphoma after chemotherapy, n = 14, range 0-0.89 cells/mm(2); colon cancer, n = 12, range 0-3.5 cells/mm(2)). In the mucosa near the ulcers, EBER-1-positive cells often surrounded and involved the glandular epithelium, forming lymphoepithelial-like lesions. The histological findings differ from post-transplant lymphoproliferative disorders or intestinal thrombotic microangiopathy, and this is the first case of EBV-associated enteritis with ulcers characterized by numerous plasma cells and lymphoepithelial-like lesions after stem cell transplantation.- - - - - - - - - - ranking = 0.2keywords = leukemia (Clic here for more details about this article) |
10/22. herpes simplex mimicking leukemia cutis.We present a patient with chronic lymphocytic leukemia who developed a painful penile ulcer that was initially diagnosed as leukemia cutis, as evidenced by an atypical leukemic infiltrate on biopsy. A Tzanck preparation was positive for multinucleated giant cells, and the diagnosis of herpes genitalis was confirmed by viral culture. In patients with hematologic malignancies, herpes simplex virus must be included in the differential diagnosis of ulcerative lesions. The histopathologic findings of inflammatory dermatoses in these patients may include an atypical infiltrate, because of the predominance of atypical inflammatory cells in the peripheral circulation.- - - - - - - - - - ranking = 1.2keywords = leukemia (Clic here for more details about this article) |
