Melanoma epidemic across the millennium: time trends of cutaneous melanoma in Emilia-Romagna (Italy) from 1997 to 2004.

BACKGROUND: After a rapid increase in malignant melanoma (MM) incidence in the last decades, trends of the melanoma epidemic in the recent years seemed not homogeneous. OBJECTIVE: This study aimed at the monitoring of some epidemiological data referring to melanoma in a region of the Northern Italy during the past 8-year period. METHODS: All cases of melanoma, including also in situ lesions, diagnosed in Emilia-Romagna and San Marino State, with the exclusion of Cesena province, from 1997 to 2004 were recorded and the incidence of melanoma, adjusted for the European standard population by the direct method, was calculated. RESULTS: Mean standardized incidence was 9.7 for invasive MMs and 11.9, considering also in situ ones, showing an ascending trend with an increment of 3.3 new incident cases in 2004 compared with 1997. No differences in age distribution, gender and site were reported. Concerning tumour thickness, although a general ascending trend in all subtypes, only thin melanoma incidence significantly increased over the study period. CONCLUSIONS: Contrary to data from Northern European countries, melanoma incidence still showed an ascending trend in the Italian population of Emilia Romagna.

Syndrome of inappropriate secretion of antidiuretic hormone in a patient affected by metastatic melanoma.

The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is characterized by hyponatraemia due to water retention resulting from the persistent release of antidiuretic hormone (vasopressin). It may occur in a variety of malignant and non-malignant conditions, in particular in association with oat cell carcinoma, pulmonary and cerebral diseases. We report the case of a male patient affected by melanoma of the right temporal region with brain metastasis who developed acute headache, drowsiness, nausea, vomiting and pathological reflexes. Clinical and laboratory investigations led us to the diagnosis of SIADH. Restriction of fluid intake obtained a good clinical improvement with normalization of laboratory alterations; after 2 months the patient experienced a new episode of SIADH which was promptly treated. As melanoma has been occasionally observed in association with SIADH it should be included in the list of tumours that can cause this particular syndrome.

Multiple miliary osteoma of the face.

A case of multiple miliary osteomas of the face in a 68-year-old female with no personal history of acne or former inflammatory skin disorders is reported. The patient showed multiple painless, stone-like formations at several sites of the face. Histological, echographic and radiological investigations confirmed the presence of bone tissue in the dermal layer. Multiple miliary osteoma of the face is considered the rarest variant of primary osteoma.

Erythema nodosum and Hodgkin's disease.

A 27-year-old woman with a 5-month history of recurrent erythema nodosum was found to have Hodgkin's disease. A temporal relationship between the two disorders suggested a causative role of the lymphoma. A review of the literature yielded 15 cases of this association, suggesting that the diagnosis of Hodgkin's disease should be considered in patients with unexplained erythema nodosum.

Prevalence of psoriatic arthritis in Italian psoriatic patients.

OBJECTIVE: To evaluate the prevalence of psoriatic arthritis (PsA) in Italian patients with psoriasis and to compare the Moll and Wright criteria, the European Spondylarthropathy Study Group (ESSG) criteria, and Amor criteria when applied to this patient population. METHODS: We examined 205 unselected patients with psoriasis. The diagnosis of PsA was based upon the clinical experience of a rheumatologist. After, we tested these classification criteria. HLA class I and II antigens were also analyzed. RESULTS: Thirty-six percent (75) of psoriatic patients were considered by a clinical expert to have PsA. Moll and Wright criteria identified 46 patients (22%) with PsA; 49 patients (24%) were identified by ESSG criteria and Amor criteria; 12 patients identified by Amor criteria but not by ESSG criteria presented enthesitis or dactylitis; 10 patients identified by ESSG but not by Amor criteria had peripheral synovitis. In patients with peripheral arthritis and psoriasis, the evaluation of NSAID response was critical to fulfilling Amor criteria. However, it was not easy to retrospectively evaluate NSAID response using these criteria. The sensitivity was low for each of the 3 classification criteria (from 61 to 65%), whereas the specificity was high (from 99 to 100%). CONCLUSION: Our study confirms a high prevalence of PsA among an unselected population of Italian patients with psoriasis. Our data reveal the inadequacy of the existing criteria for PsA, including the ESSG criteria and Amor criteria for the classification of spondyloarthropathy.

Self-detected cutaneous melanomas in Italian patients.

Self-detection of suspicious pigmented skin lesion combined with rapid referral to dermatologic centres is the key strategy in the fight against melanoma. The investigation of factors associated with pattern of detection of melanoma (self- vs. nonself-detection) may be useful to refine educational strategies for the future. We investigated the frequency of melanoma self-detection in a Mediterranean population at intermediate melanoma risk. A multicentric survey identified 816 consecutive cases of cutaneous melanoma in the period January to December 2001 in 11 Italian clinical centres belonging to the Italian Multidisciplinary Group on Melanoma. All patients filled a standardized questionnaire and were clinically examined by expert dermatologists. Self-detected melanomas were 40.6%, while the remaining lesions were detected by a dermatologist (18.5%), the family physician (15.2%), other specialists (5%), the spouse (12.5%), a friend or someone else (8.2%). Variables associated with self-detected melanomas were female sex, young age, absence of atypical nevi, knowledge of the ABCD rule, habit of performing skin self-examination. Self-detected melanomas did not differ from nonself-detected tumours in term of lesion thickness; however, patients with self-detected melanomas waited a longer period before having a diagnostic confirmation (patient's delay) (> 3 months: odds ratio, 3.89; 95% confidence interval, 2.74-5.53). In order to reduce the patients' delays, educational messages should adequately stress the need for a prompt referral to a physician once a suspicious pigmented lesion is self-detected.
