Cutaneous lymphomas comprise a heterogeneous group of lymphoproliferative disorders with skin involvement and are classified as a subgroup of non-Hodgkin lymphomas. From 1981 to 2007, 100 children with non-Hodgkin lymphomas were admitted to the Hematology Unit of the Federal University of Minas Gerais Teaching Hospital. In nine of these children, the skin was involved at the onset of the diseas...

BACKGROUND As the life expectancy of persons infected with human immunodeficiency virus (HIV) increases, cancers have become an important cause of morbidity and mortality. Although cutaneous cancers are the most common malignant neoplasms in the general population, little data exist among HIV-positive persons, especially regarding the impact of HIV-specific factors. METHODS We evaluated the i...

NK/T-cell lymphoma (NKTCL) is characterized by the expression of the NK-cell antigen CD56. Non-nasal NK/T-cell lymphomas are subdivided into primary cutaneous and 4 subtypes of secondary cutaneous lymphomas; nasal type, aggressive, blastic (blastoid), and other specific NK-like cell lymphoma. Aggressive NK/T-cell lymphoma/leukemia is a rare leukemic variant of nasal type NKTCL. We herein report...

Schwannoma is a benign encapsulated nerve sheath tumor composed of Schwann cells, that may arise anywhere along the course nerve. Cutaneous schwannomas, associated with peripheral nerves, usually present as slow-growing well-circumscribed nodule, localized in dermis or subcutaneous tissue. They are generally asymptomatic; however, they become painful by nervous compression. Since clinical signs...

Background: Serious cutaneous eruptions caused by cytarabine are never reported in China. Methods: We admitted a 43-year-old man who was diagnosed with acute non-lymphocytic leukemia, and was given several chemotherapy regimens including cytarabine. And when FLAG regimens were given in the patient, the serious pustular eruption appeared. Results: After the treatment, cutaneous eruption was grad...

Primary cutaneous lymphomas (PCLs) are the second most common group of extranodal non-Hodgkin lymphomas (NHL) with an estimated annual incidence of 1/100.000. Interferons (IFNs) are used in mono or combination therapy for cutaneous lymphomas especially for cutaneous T-cell lymphomas (CTCL) for years. IFN-α is the most widely-used type for cutaneous lymphomas. IFN-α has been shown to be a highly...

BACKGROUND Subacute cutaneous lupus erythematosus is a nonscarring, non-atrophy-producing photosensitive cutaneous disorder. Half of the patients have 4 or more of the criteria for classification as systemic lupus erythematosus. In some patients, drugs induce or exacerbate the cutaneous disease. OBSERVATION We describe 5 patients who had either an exacerbation or a new onset of subacute cutan...

The skin is an unusual location for métastases from visceral carcinoma, and cutaneous métastases from gastric carcinoma are rare. Cutaneous métastases display various clinical features, but usually occur as non-specific firm nodules. However, no cases of occult métastases from gastric carcinoma have been reported. We describe here a patient with clinically unapparent cutaneous metastasis fi^om ...

Analysis of the literature on cutaneous leishmaniasis in low-prevalence countries suggests an increase in imported cases that is attributable to the growing phenomenon of international tourism, migration and military operations in highly endemic regions. Cases of imported cutaneous leishmaniasis are often missed initially, but diagnosis can be made non-invasively by PCR using skin scrapings of ...
