Development of lepromatous leprosy following etanercept treatment for arthritis.

We present a case of a patient treated with etanercept (TNF-a antagonist) for psoriatic arthritis, who then developed clinical symptoms of lepromatous leprosy. She presented with multiple erythematous plaques on trunk, face and extremities, saddle nose deformity, alopecia, articular deformities of the feet and peroneal neuropathy. The clinical suspicion of Hansen's Disase was confirmed by the biopsy findings (lepromatous leprosy). On further questioning, the patient stated that her father was diagnosed with leprosy 70 years ago and had spent some years in a leper colony in Spinalonga island in Southern Greece in the 1940s. This first report of Hansen's disease after administration of etanercept highlights the need of careful risk assessment of patients for whom antiTNF treatment is planned.

Malassezia folliculitis presented as acneiform eruption after cetuximab administration.

Cetuximab, a new recombinant monoclonal antibody that inhibits the epidermal growth factor receptor (EGFR), is frequently associated with cutaneous reaction. A 85-year-old male with a diagnosis of adenocarcinoma of the right parotid gland referred to our department for persistent acneiform eruption on the face and trunk induced after cetuximab administration. Despite cetuximab discontinuation and administration of antibiotics as well as topical steroids, the skin lesions were persisted for several months. Interestingly, the pustules and the acneiform eruption showed significant improvement after a course of oral itraconazole. The latter was given when the microscopic examination of the pus obtained from the lesions revealed the presence of Malassezia folliculitis.

The diagnostic importance of photosensitivity dermatoses in chronic alcoholism: report of two cases.

Many of the vitamin deficiency diseases have been almost completely eliminated in developed countries. Niacin deficiency is considered one of them. However, cases of pellagra are recently reported in West Europe, USA, Australia, and Japan in connection with chronic alcoholism, gastrointestinal malabsorption, and some medications. We report two cases of pellagra, manifesting as photosensitivity dermatoses with mental deterioration in chronic alcoholic abusers in the Mediterranean basin, the island of Crete in Greece. The report highlights the fact that all physicians should be alerted to photosensitivity dermatoses in alcoholics; early treatment with multiple vitamin therapy, including nicotinic acid should be initiated in these patients.

The incidence of cutaneous melanoma on Crete, Greece.

BACKGROUND: For Greece, no data regarding the incidence of cutaneous melanoma (CM) have been reported. In this report, we present epidemiologic data for CM on Crete, an island in southern Greece, during the years 1999-2002. We attempt a comparison with corresponding data reported for the Italian population. METHODS: One hundred and two CM patients of Cretan origin with primary CM first diagnosed between the years 1999-2002 were interviewed and underwent complete skin examination by the same two experienced dermatologists. Crude and/or age-standardized incidence rates were calculated for Crete as a whole, as well as for each one of the four prefectures of the island. RESULTS: The age-standardized incidence rate according to the Greek population was 4.6 per 100,000 person-years for men and 4.7 per 100,000 person-years for women. The crude incidence rates did not differ significantly between the four prefectures. Significant differences between Cretan and Italian CM patients were found in terms of gender, age at diagnosis, anatomic site and histogenetic type of CM, hair color, skin reaction to sun exposure, history of sunburn before the age of 15 years, presence of solar lentigines, and total common nevus count. CONCLUSIONS: The incidence of CM on Crete is higher than that estimated for the whole of Greece and comparable with the incidence reported for other southern European countries.

Dermatological manifestations in primary biliary cirrhosis patients: a case control study.

OBJECTIVES: Primary biliary cirrhosis (PBC), a disease of probable autoimmune etiology that affects the small intrahepatic bile ducts of mainly middle-aged women is commonly associated with pruritus, xanthomatous lesions, and melanosis. We conducted a prospective study to systematically describe the skin disorders of a group of PBC patients. METHODS: A prospective evaluation and analysis of dermatological manifestations including oral and genital lesions was carried out, in 49 PBC patients (45 females and 4 males). Median age 63 yr (range 35-87 yr). They were compared with 45 age and sex matched controls, selected among persons attending the dermatologic outpatient clinic. RESULTS: A total of 330 skin disorders were found in the 49 PBC patients versus 76 in the 45 controls; 31.5% of all lesions were skin fungal infections. Of all lesions analyzed with the Bonferroni rule of multiple comparisons significantly more common in PBC patients were plantar mycoses, onychomycoses, and interdigital mycoses. Pruritus was found in 69.3% of patients versus 22.2% of controls, xerosis in 69.3%versus 2.2%, dermographism in 57.1%versus 4.4%, and melanosis in 46.9%versus 0%. In 38.7% of the PBC patients the dermatologic lesion was the presenting symptom. CONCLUSIONS: PBC patients present with a wide variety of cutaneous manifestations varying in severity. Multiple skin fungal infections have been found even in the early stages. Since in more than one third of our PBC patients the dermatologic lesion was the presenting sign or symptom leading to diagnosis we believe that physicians should be aware so that a prompt and early diagnosis may be achieved.

Scleredema adultorum of Buschke presenting as periorbital edema: a diagnostic challenge.

Scleredema adultorum is a rare sclerotic disorder characterized by diffuse swelling and nonpitting induration of the skin. Its occurrence has been documented in association with infections, diabetes mellitus, paraproteinemia, multiple myeloma, and monoclonal gammopathy. We report an unusual case of a 48-year-old man with an asymptomatic bilateral eyelid edema of sudden onset. During a period of 6 months, the condition slowly progressed to extensive nonpitting edematous swelling restricted to the periorbital sites. The presumptive diagnosis of scleredema adultorum was confirmed by the presence of typical histologic findings. This case is unique in that the periorbital swelling remained as the sole clinical manifestation of scleredema during the 5-year follow-up and was complicated with partial vision blockage.

Epidemiological differences for cutaneous melanoma in a relatively dark-skinned Caucasian population with chronic sun exposure.

The aim of this study was to reveal differences in the epidemiology and to identify significant risk factors for cutaneous melanoma (CM) in a relatively dark-skinned, chronically sun-exposed Caucasian population. This group is considered to have a low risk for this tumour. One hundred and ten newly diagnosed patients with primary CM and 110 age- and gender-matched controls, all of Cretan origin, were interviewed and underwent a complete skin examination. Solar keratoses odds ratio (OR) 6.2 and lentigines (OR 2.2), common and atypical naevi (OR 5.4 and 3.0, respectively), blonde or red hair colour (OR 3.1), skin phototypes I/II (OR 1.8), as well as total sun exposure (weeks per year) (OR 1.03), were all significantly associated with CM risk in a multivariate logistic regression analysis. In the relatively dark-skinned Cretan population, sun exposure indices represent the most important risk markers for CM which contrasts with data from fair-skinned Caucasian populations where melanocytic naevi are the main risk factors.
