Isolated Cutaneous Chronic Lymphocytic Leukemia: A Case Report.

Skin lesions in chronic lymphocytic leukemia (CLL) have been reported in between 4% and 20% of patients with CLL and are a rare entity compared with T-cell leukemia. They can present mainly as leukemic cutis or, frequently, as secondary lesions such like urticaria, itching, pyoderma gangrenosum, cutaneous vasculitis, Sweet's syndrome, and erythroderma. We report on an adult patient who developed a skin lesion of forearms and hands, leading to the discovery of isolated cutaneous CLL after two biopsies. Isolated CLL cutaneous location is very rare and may be diagnosed late, as in the case of our patient. A better knowledge of the course of the illness and rapid diagnosis of this CLL cutis leukemia will enhance the therapeutic efficacy of the disease.

Chondrosarcoma of the Nasal Cavity and Paranasal Sinuses: A Rare Entity.

Background: Chondrosarcomas are slow-growing malignant tumors that originate in cartilaginous structures. They typically manifest in the head and neck region, with a preference for the maxillofacial skeleton, particularly the mandible and maxilla. However, chondrosarcoma of the sinonasal tract is exceptionally rare, and only few cases have been reported. Case Presentation: This report details the case of a 43-year-old woman who incidentally discovered chondrosarcoma in the maxillary and ethmoid sinuses with nasal extension. Subsequently, the patient underwent surgery via a paralatero-nasal approach with adjuvant radiotherapy. The aim of this study was to describe the clinical findings, management, and outcome of sinonasal tract chondrosarcoma. Conclusions: The primary treatment for chondrosarcomas remains surgery, with a transnasal endoscopic approach offering a viable option for complete resection in select cases.

Primary B cell lymphoma of the tongue base: a case report.

Primary non-Hodgkin's lymphoma's of the tongue is very rare and accounts for 1% of all malignant tumor of the oral cavity. Clinical features are non-specific ulcerative lesions that do not heal. In the literature, the majority of cases are diffuse large B cell type however, T cell phenotype also may occur. We describe a 77 years old man, who presented with an ulcerative mass in the left margin of the tongue the diagnosis diffuse large B cell lymphoma was confirmed. The patient is actually on treatment R-mini CEOP and has favorable evolution.

Chronic myeloid leukemia as a secondary malignancy after lymphoma in a child. A case report and review of the literature.

BACKGROUND: Philadelphia chromosome-positive chronic myeloid leukemia (CML) in children is very rare. CML occurring as a secondary malignancy in individuals treated for diffuse large B-cell lymphoma (DLBCL) is also rare. CASE REPORT: We present the case of a 5-year-old female patient who developed a right orbital mass that was diagnosed as DLBCL. 9 months after receiving treatment for DLBCL, she presented with a white cell count of 250,000/mm(3). Peripheral blood and bone marrow (BM) evaluation revealed a myeloproliferative disorder. Cytogenetic and molecular studies demonstrated the presence of t(9;22). CML following DLBCL has not been previously described in the younger population. To our knowledge, this is the first report of a child who developed a CML as a second malignancy after DLBCL. Therapy-related CML and non-therapy-related secondary CML are discussed as potential explanations of this highly unusual clinical presentation. CONCLUSION: Hematological disorders such as CML may occur after lymphomas. With the increased use of BM cytogenetic studies during staging for lymphoid malignancies, future studies may be able to clarify the question of whether the CML clone in some of these patients existed before treatment for lymphoma.
