Objective: To study the exact frequency and the histological features of cutaneous intolerance to mechlorethamine (CIM) hydrochloride therapy in patients with cutaneous T-cell lymphomas, including Langerhans cell histiocytosis.
Design: A multicenter prospective study was conducted from January 1, 1994, to May 31, 1996, in 12 different hospitals in France.
Patients: Of the 52 patients with cutaneous T-cell lymphomas or Langerhans cell histiocytosis, 35 were men and 17 were women, aged 18 to 87 years.

We studied 21 HIV-associated lymphomas with cutaneous presentation to determine whether they showed features of primary cutaneous lymphoma arising fortuitously or whether they represented the cutaneous involvement of AIDS systemic lymphoma. Besides rare mycosis fungoides (n = 3), which shared typical clinicopathologic lesions, nonepidermotropic large-cell lymphomas (n = 18) were predominant. They frequently presented as a solitary nodule or tumor.

The cause and pathogenesis remain unclear. The aim of the present study was to determine whether Chester-Erdheim disease is a polyclonal reactive disease or a clonal neoplastic disorder.

Observation: We report a 21-year-old woman, who presented with acquired cutis laxa on the face and the ear lobes. Urticarial papules had preceded for 6 years.

We present a case of pulmonary arteriovenous malformation (PAVM) in central localisation (type IIIa) of the upper lobe of the left lung. We discuss diagnostic (Doppler ultrasonography, CT, MRI, angiography) and therapeutic (embolization therapy) options and a current role of surgery in this uncommon clinical condition. Our patient underwent left upper lung lobectomy as an ultimate therapeutic method without subsequent morbidity.

Case Report: A 75-year-old woman presented violaceous papules on the right thigh.
Background: Pilotropic cutaneous T-cell lymphomas without mucinosis are rare, with 27 cases previously reported. Diagnosis and classification may be difficult. The clinical course and histopathological and immunohistochemical findings in 5 patients are described.

Our aim was to identify independent prognostic factors in a large series of patients with non-MF/SS PCL. We evaluated 158 patients who were registered in the French Study Group on Cutaneous Lymphomas database from January 1, 1986 to March 1, 1997.
View Article and Find Full Text PDFPseudoepitheliomatous hyperplasia has occasionally been reported in cutaneous T-cell lymphoma (CTCL). This association raises the question of the relationship between epidermal hyperplasia and the lymphomatous infiltrate. Because epidermal growth factor (EGF) and transforming growth factor-alpha (TGF-alpha) have been demonstrated to be involved in epidermal proliferation through binding to EGF receptor (EGFr), we tested the hypothesis that these cytokines could be secreted by lymphomatous cells, and induce the overlying pseudoepitheliomatous hyperplasia.

Whether the detection of clonal immunoglobulin gene rearrangement in the cutaneous lesion is predictive of a malignant outcome remains controversial. We therefore studied cases of cutaneous lymphoid hyperplasia by polymerase chain reaction analysis.

The indication for treatment of obesity is based on exact diagnostic procedures. This paper will critically discuss clinical and biochemical approaches to the diagnosis of obesity.

Unfortunately currently available drugs did not prove effective in the long term treatment of obese patients. Fenfluramin and D-Fenfluramin has been withdrawn from the market because of severe side effects as pulmonary hypertension and valvular heart disease.

However, other autoimmune bullous skin diseases such as paraneoplastic pemphigus or bullous lupus erythematosus may also be associated with lichenoid eruptions.
Objective: Our purpose was to describe 3 African patients with a similar form of lichenoid erythrodermic BP.
Although mycosis fungoides (MF) is considered to be an indolent lymphoma, survival is highly influenced by TNM stage. At diagnosis, most MF patients present with early stage disease and a high probability of long-term survival. Treatment is generally directed towards skin lesions, and achievement and duration of complete responses are variable.

Primary cutaneous disease, spontaneous regression, and absence of extracutaneous spreading (but not age < or =60 years) were associated with a better prognosis.

However, the biopsies showed an epidermotropic infiltrate of small irregular CD4+ lymphocytes, and detection of a T-cell clone in the lesions by polymerase chain reaction confirmed the diagnosis of mycosis fungoides. Thus, keratosis lichenoides chronica can be an unusual and potentially misleading presentation of mycosis fungoides.

It is characterized by bullae arising on lichen planus papules and on uninvolved skin, subepidermal bullae in histology, and linear deposits of IgG and C3 along the basal membrane zone on immunofluorescence of peribullous skin. Our goal was to identify the localization of the target antigen in cases of LPP.

Upon metabolism by cytochrome P450, carbamazepine may produce reactive metabolites. We evaluated in vitro the covalent binding of carbamazepine reactive metabolites on human P450s and then the presence of these P450s in human epidermis.

Recently, using molecular techniques, the detection of a dominant T-lymphocyte clone has been reported in cutaneous lesions of MF. The aim of the present study was to determine the diagnostic value of a dominant T-lymphocyte clone as assessed by PCR-DGGE in early MF.
