Palmoplantar filiform hyperkeratosis with Darier's disease. Association or coincidence?

Palmoplantar orthokeratotic filiform hyperkeratosis is characterized by multiple, spiny, keratotic projections. We report a new case, occurring in an 85-year-old woman, associated with typical Darier's disease involving her chest and groin, that may be not fortuitous. Three previous reports point out its possible association with underlying diseases, such as malignancy or Darier's disease.

Porphyria cutanea tarda associated with human immunodeficiency virus infection.

Since 1987, about 60 cases of porphyria cutanea tarda (PCT) associated with human immunodeficiency virus (HIV) have been reported. The respective roles of HIV and toxic hepatic factor in PCT remain unclear. We report 10 new cases and analyse the following toxic hepatic factors: hepatitis C and B, alcoholism, drugs. The route of HIV transmission to these 10 men were: IV drugs abuse (3), homo/bisexuality (4), heterosexuality (1), and unknown (2). When PCT was diagnosed, their average age was 38 years (29-54) and the HIV-infection had been established for 4.8 years (0.33-9). Seven men had HIV-related symptoms and a CD4+ lymphocyte count below 200/mm3. Cutaneous signs and urinary porphyrin count were characteristic. Alcohol abuse was present in 8/10 patients. AST, ALT and/or gamma GT were high in 9/10 patients; 5/10 patients had HCV antibodies (4 were HCV-PCR positive). HBs antigenemia was negative among the 5/8 patients with HBV antibodies; 10/10 patients took prescribed hepatotoxic drugs. Our series confirms the presence of toxic hepatic factors in PCT of HIV-positive patients. Hepatitis C, alcoholism and hepatotoxic drug consumption seem to be triggers for the appearance of PCT in HIV-positive patients.

[Linear radiodermatitis following total body electron beam therapy]. / Radiodermite linéaire de superposition, secondaire à une électronthérapie corporelle totale.

BACKGROUND: We describe herein a peculiar clinical presentation of a linear overlapping radiodermatitis, localized on the internal side of the limbs, following a total body electron beam therapy. CASE REPORT: A 68-year-old-man was treated in April 1998 by a total body electron beam therapy, for a stage I mycosis fungoides. Few days after the last irradiation, the patient suffered from a linear eruption localized on the internal side of the limbs and the external side of the abdominal wall. DISCUSSION: Total body electron beam therapy can be proposed in early stage mycosis fungoides with localized or generalized cutaneous lesions. Because penetration depth of electron is well controlled and is limited to the skin, usual side effects of total body electron beam therapy do not concern internal organs (bone marrow,.). We report here a peculiar clinical presentation of a linear radiodermatitis in frontal plane which has not been reported to date, to our knowledge. This radiodermatitis corresponds to overlapping of posterior and anterior fields of irradiation.

[Cutaneous and neurologic vasculitis disclosing EBV-selective immunodeficiency]. / Vasculite cutanée et neurologique révélatrice d'un déficit immunitaire sélectif vis-à-vis du virus d'Epstein-Barr.

INTRODUCTION: Purtilo's syndrome or X-linked lymphoproliferative syndrome (XLP) is a rare genetic disorder affecting boys who have a selective immunodeficit towards Epstein Barr Virus (EBV) and who develop extremely severe forms of EBV infection, of which there are four major types: severe or fatal infectious mononucleosis (60 p. 100), lymphoma (23 p. 100), acquired hypo- or agamaglobulinemia (25 p. 100) and anemia or pancytopenia. We report a case of vasculitis (cutaneous and neurologic) which led to the discovery of a selective immunodeficit towards EBV, similar to Purtilo's syndrome. CASE REPORT: A 17 year-old male with no significant past medical history presented with an eruption initially felt to be consistent with pityriasis lichenoid. Treatment with erythromycin was initiated, this did not prevent the subsequent eruptions of cutaneous vasculitis lesions which were severe, prolonged, debilitating, and associated with fever and general deterioration of the patient condition. All etiologic studies were negative. A course of systemic corticosteroids was begun, but the cutaneous eruptions persisted; and in addition the patient developed signs of polyneuropathy in the lower extremities secondary to neurologic vasculitic lesions. New studies revealed an abnormal EBV serology (absence of anti-EBNA antibodies) as well as hypogammaglobulinemia, suggestive of a selective immunodeficit towards EBV resembling Purtilo's syndrome. DISCUSSION: In our patient, the development of an extensive vasculitis, characterized histologically by an intense lymphocytic infiltrate, positive for EBV, associated with hypogammaglobulinemia, and with abnormal serology suggests an anomaly in the immune response to EBV. Although the age of the patient and absence of family history make the Purtilo's syndrome uncertain, the nature of the immunodeficit is very similar and the patient could well develop a lymphoma. This case is significant in that the disease initially manifested itself as a cutaneous vasculitis, which was not been described previously.

Prognostic factors in primary cutaneous lymphomas other than mycosis fungoides and the Sézary syndrome. The French Study Group on Cutaneous Lymphomas.

Prognostic studies of primary cutaneous lymphomas (PCL) other than mycosis fungoides (MF) and the Sézary syndrome (SS; non-MF/SS PCL) have been mainly performed on subgroups or on small numbers of patients by using univariate analyses. 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. Variables analyzed for prognostic value were: age; sex; type of clinical lesions; maximum diameter, location, and number of skin lesions; cutaneous distribution (ie, local, regional, or generalized); prognostic group according to the European Organization for Research and Treatment of Cancer (EORTC) classification for PCL; B- or T-cell phenotype; serum lactate dehydrogenase (LDH) level; and B symptoms. Univariate and multivariate analyses were performed using a model of relative survival. Forty-nine patients (31%) died. The median relative survival time was 81 months. In univariate analysis, EORTC prognostic group, serum LDH level, B symptoms, and variables related to tumor extension (ie, distribution, maximum diameter, and number of skin lesions) were significantly associated with survival. When these variables were considered together in a multivariate analysis, EORTC prognostic group and distribution of skin lesions remained statistically significant, independent prognostic factors. This study confirms the good predictive value of the EORTC classification for PCL and shows that the distribution of skin lesions at initial evaluation is an important prognostic indicator.
