IntroductionThe incidence of melanoma has increased more than that of any other type of malignant tumor. Our aim was to analyze the changes in incidence of cutaneous melanoma in recent years in a Mediterranean population.Material and methodsPatients with melanoma diagnosed between 1988 and 2006 were included in the study. Data from the first half of this period were compared with data from the second half.ResultsThe number of in situ melanomas increased from 36/302 cases (11.92 %) in the first half of the period to 224/724 (30.94 %) in the second half. Melanomas measuring more than 4 mm increased from 29/302 cases (9.60 %) to 62/724 (8.56 %). The mean maximum thickness for the whole study period was 1.91 mm and was similar for both halves.ConclusionsThe increase in incidence of melanoma in our population was due mainly to an increase in incipient cases. The proportion of melanomas larger than 4 mm remained constant, although, in absolute terms, twice as many such melanomas were detected per year. We believe that campaigns for prevention and early detection must continue, and should focus in particular on the older population. 相似文献

Background and objectives Pyoderma gangrenosum (PG) is a disorder, included in the spectrum of neutrophilic and auto‐inflammatory dermatoses, whose clinical aspects and outcome we intend to characterize. Materials and methods In a retrospective study based on files of patients diagnosed during a 10‐year period (2000–2009), we evaluated demographic data, anatomic locations, number of lesions, clinical variants, associated diseases, treatment regimens, healing time, and recurrence. Results A total of 24 patients were included, 19 women and five men (F/M = 3.8/1), aged between 17 and 89 years (mean 58.3 ± 24.6 years) with a diagnosis of PG. Lesions, single in 15 patients (62.5%) and multiple in nine (37.5%), were localized in the lower limbs in 19 patients (79.2%), upper limbs (4), abdomen (4), face (2) and genital area (1). Clinical variants observed were ulcerative (17 patients), pustular (4), bullous (2) and superficial granulomatous (1). Associated systemic diseases were observed in 18 patients (75%), gastrointestinal in seven patients (29.2%), hematological in seven (25%), autoimmune inflammatory in three (12%), and solid tumors in two (8.3%). Systemic steroids were used in the treatment, either alone in 10 patients (41.7%) or combined with cyclosporine in eight (33.3%). Complete healing was achieved in 20 patients, on average five months after diagnosis, but lesions recurred one or more times in four patients (16.7%). Conclusions As reported in the literature, PG is a rare disorder, more common in females, frequently associated with systemic disease, which compromises the prognosis. 相似文献

Background:
Cutaneous tuberculosis (TB) is essentially an invasion of the skin by Mycobacterium tuberculosis, the same bacteria that causes pulmonary tuberculosis.Aim:
This study was conducted to study the common types of cutaneous TB and to find the management pattern in a tertiary teaching hospital in Pokhara, Nepal.Materials and Methods:
All the cases of cutaneous TB were biopsied and furthermore investigated by performing Mantoux test, sputum examination, fine needle aspiration cytology, chest X-ray and ELISA.Results:
In this study, we found that tuberculosis verrucous cutis (48%) had a higher incidence than other types of cutaneous TB. More males were affected than were females (1.2:1). Commonly affected sites were the limb and the buttock (48%). The most commonly affected age group was 16–25 years (40%). All cases (except two) were more than 15 mm in size in the Mantoux test. The histopathological picture was typical in all except three cases. All patients were treated with antitubercular treatment as per the national guidelines.Conclusion:
The most common type of cutaneous TB was tuberculosis verrucous cutis and the most commonly affected sites were the limb and the buttock. As cutaneous TB sometimes reflects the presence of pulmonary tuberculosis, its incidence should not be ignored. 相似文献6.

Background Standard treatment for onychomycosis often results in less than half of subjects achieving disease‐free nails. Onychomycosis is even more challenging to treat as relapses and re‐infections are common. Objective To determine if a prophylactic effect exists when a treatment with amorolfine nail lacquer (ANL), with half the frequency of the standard regimen, is instituted following successful treatment of dermatophytic toenail onychomycosis with matrix involvement. Methods Efficacy and safety of a group treated with ANL (once every 2 weeks) were compared with that of an untreated group in a 36‐month (3 years), single‐centre, randomized, open‐label, comparison study. Subjects to be included in the study were required to be cured of confirmed onychomycosis with matrix involvement after an initial treatment with either ANL + oral terbinafine or oral terbinafine alone in a previous study. Prophylaxis of onychomycosis was assessed by global recurrence rate, confirmed onychomycosis, clinical recurrence and mycological recurrence. Results A total of 52 subjects were enrolled (26 in each group) in the study. Throughout the study, recurrences occurred more quickly in the untreated group compared with that in the ANL group. Statistically significant differences were observed at month 12 (ANL, 8.3%; untreated, 31.8%; P = 0.047). At endpoint, 70.8% of the subjects treated with ANL remained cured compared to 50% in the untreated group (P = 0.153). Recurrence was delayed by nearly 200 days for the ANL group compared with that of the untreated group. Amorolfine was safe and well tolerated during the study, with no treatment‐related adverse events. Conclusion These results suggest that amorolfine nail lacquer may be effective and is safe for use as a prophylactic treatment for the recurrence of onychomycosis. 相似文献

Slow‐growing sarcomas may give rise to intractable wounds, which may be attributed to commoner causes. A 57‐year‐old man with diabetes mellitus presented with a 24‐year history of a chronic wound that originated on his left great toe. Because of the long history, the nonspecific histological findings and the complication of ulcerative colitis, we misdiagnosed his ulcer as pyoderma gangrenosum. The wound was eventually diagnosed correctly by histological examination of a skin biopsy and the use of immunohistochemistry to detect cytokeratin, epithelial membrane antigen and vimentin. Specimens obtained 16 years earlier showed the same staining pattern. Radiological examinations revealed no metastasis. The patient received a below‐knee amputation without further chemotherapy or radiotherapy. When patients have intractable ulcers, appropriate biopsies and immunohistochemical examinations are sometimes necessary to exclude a malignancy even if the history and symptoms do not suggest a diagnosis of sarcoma. 相似文献

Psoriasis is a chronic relapsing disorder which shows variable clinical features. The long‐term clinical study with many patients is important to elucidate the epidemiologic characteristics and clinical features of psoriasis. The purpose of this study was to analyze the epidemiologic characteristics and clinical features of psoriasis in Korean patients. Epidemiologic and clinic data and assessments for severity of extent and activity of psoriasis were collected from the medical records of 5084 patients, who had been newly diagnosed with psoriasis in the Psoriasis Clinic of Seoul National University Hospital between 1982 and 2012. The sex ratio of the psoriasis patients was 1.2:1 (male 54.6%, female 45.4%). The peak age of onset in males was 20s, while it was the teenage years in females. A total of 63.5% of patients developed psoriasis before 30 years of age. Family history of psoriasis was observed in 26.0% of patients. Moderate to severe extent of involvement were more frequently observed in male patients and patients under 30 years of onset age than in females and patients 30 years or over of onset age, respectively. Moderate to severe disease activity were also more frequently presented in male patients, but not in patients under 30 years of onset age. The most common morphological type was nummular (56.7%), followed by large plaque (28.5%) and guttate (8.5%). Nail involvement accompanied in 26.4% of patients. We demonstrated the epidemiologic and clinical characteristics of psoriasis in Korean patients. 相似文献

Skin diseases are common in hospitalized patients. However, there is a lack of data
concerning their frequency. The objective of this study is to evaluate the prevalence
of dermatological diagnoses in hospitalized patients after consultation requested by
nondermatologist physicians to the Department of Dermatology, Hospital de Clinicas de
Porto Alegre period of 10 years. A total of 5685 patients were evaluated,
representing an average of 48.2 patients per month. The five most frequent groups
were infectious dermatoses(33.25%), eczematous dermatoses (11.49%), drug reactions
(11.43%), vascular dermatoses (6.81%) and group of pruritus, prurigo nodularis and
urticaria (hives) (4.71%). 相似文献

Background: Rising melanoma incidences have created the need of assessment of epidemiological and clinical data. Patients and methods: We investigated the natural history of invasive cutaneous melanoma in Styria, a province of Austria, in the years 2001–2003. 1082 patients, 511 men and 571 women, mean age 58.2 ± 16.7 years, were collected. Besides basic melanoma data, special histologic features such as regression structures, ulceration, microsatellites and vascular invasion were investigated. Furthermore, lymph node pathology in case of sentinel node biopsy and/or lymph node dissection was recorded. Results: Mean annual incidence (crude rate) was 28.6 per 100,000 inhabitants, age standardized rate 24.5 per 100,000 (95 % CI 22.4–26.6). Cumulative risk (0– 74 years) was 1.92, lifetime risk 1 in 52. Superficial spreading melanoma was the most common type in both sexes, men on the trunk and women on the extremities. Only 11 % of all melanomas were in easily visible areas. Median tumor thickness was 0.75 mm, ranging between 0.2 and 50.0 mm. Sentinel node biopsy was performed in 158 melanomas (14.6 %),and was positive in 22 %.Primary therapeutic lymph node dissection was performed in 19 patients, showing metastases in 18 patients. Conclusions: The investigation revealed an unclear high melanoma incidence for invasive melanomas in our province, requiring further investigation. 相似文献

Background During the last decades, the progressive ageing of the population has resulted in a rising skin cancer incidence. Although previous studies detected no higher morbidity for dermatological surgery in senior patients, their exclusion from optimal surgical treatment remains as a common clinical practice. Objective The aim of this study was to determine the diseases treated with ambulatory major dermatological surgery, the surgical morbidity and the associated variables in ≥85 year‐old patients. Patients/methods This is an observational study on 247 successive patients older than 85 years of age who underwent dermatological surgery in a single Ambulatory Mayor Surgery unit. Studied variables were age, gender, tobacco‐alcohol exposure, co‐morbid medical conditions, blood‐thinning medication, antibiotic prophylaxis, number of lesions, location, histopathological diagnosis, area of skin removed, surgical technique, type of flap, length of surgery, entrance order, suture thread, surgical complications and need of post‐operative admission. Results The most common site was head and neck (82.7%). The most frequent tumour was basal cell carcinoma (45.1%), followed by squamous cell carcinoma (38.7%) and melanoma (8.3%). Direct closure was the most frequent procedure (55.6%). Of the total number of patients, 7.9% of patients suffered complications; necrosis followed by cellulitis were the most frequent. Length of surgical procedure, area of skin removed and reconstruction with skin‐graft were significantly related to higher risk of post‐operative complications. Conclusions No intra or post‐surgical mortality or life‐threatening local complications were detected. Most post‐surgical local complications appeared after wide excisions and complex reconstruction techniques that prolonged the length of the surgery. 相似文献
