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...

Cutaneous B cell lymphoma (CBCL) is a lymphoproliferative disorder of neoplastic B cell of the skin with a wide range of clinical manifestations. Commonly, the clinical features of CBCL are plaques, nodules, or ulcerative lesions. Skin is one of the common sites for extra-nodal lymphomas in patients with AIDS and B cell type is less common than T cell type. Only recently, the existence of B cel...

Sir, Acquired ichthyoses can either reflect an underlying severe disorder or may be an atypical expression of skin diseases such as cutaneous T-cell lymphomas (1). Otherwise, lymphomatous infiltrates in the skin can cause heterogeneous cutaneous symptoms and lesions, which may range from invisible features to massive tumour nodules. Mycosis fungoides is an epidermotropic cutaneous T-cell lympho...

The aim of this study was retrospectively to assess the validity of the 2005 WHO-EORTC classification for primary cutaneous lymphomas (PCL) in a large cohort of patients of a single German skin cancer unit. All patients with PCLs consecutively visiting our hospital between January 1980 and December 2005 were included in a retrospective monocentre study, analysing their histological and clinical...

Cutaneous lymphomas are classified according to their cellular origin into T-cell lymphoma and B-cell lymphoma. The annual incidence rate is 0.3 per 100,000 population. We report a case of a 56-year-old male patient who presented with a two-month history of nodules of varying sizes, some ulcerated, on the face, abdomen, and upper limbs. Histopathological examination and immunohistochemical stud...

PURPOSE To discuss vorinostat approval for treatment of cutaneous manifestations of advanced cutaneous T-cell lymphoma (CTCL). EXPERIMENTAL DESIGN Data from 1 single-arm, open-label, multicenter pivotal trial and 11 other trials submitted to support the new drug application for vorinostat in the treatment of advanced primary CTCL were reviewed. The pivotal trial assessed responses by changes ...

Primary cutaneous anaplastic large cell lymphoma is a T-cell malignancy with atypical CD30 positive lymphocytes. Pseudoepitheliomatous hyperplasia is an uncommon finding in primary cutaneous anaplastic large cell lymphoma, and may mimic squamous cell carcinoma as pseudomalignancy. Careful attention of a pathologist to correct diagnosis of pseudoepitheliomatous hyperplasia and its underlying cau...

Primary cutaneous CD30+ lymphoproliferative disorders (LPDs) are the second most common group of primary cutaneous T-cell lymphomas (CTCLs). The spectrum of LPDs includes lymphomatoid papulosis (LyP), primary cutaneous anaplastic large cell lymphoma (C-ALCL) and borderline cases. The term "borderline lesions" refers to cases where histological features are similar to LyP, but clinically behave ...
