“…Compared with Caucasians, the total number of patients with melanoma was low in our study. The most common type of melanoma was the same as reported by Chen et al [13]in Taiwan as acral lentiginous melanoma. 14 out of 16 melanomas belonged to the acral lentiginous type located on the soles.…”

Background: Geriatric health care has become a worldwide concern, but relatively few statistical studies are available about geriatric skin diseases. Moreover, no information exists regarding skin disorders among the elderly population in Taiwan that has become a geriatric country. Objective: To determine the characteristic pattern and the prevalence of various skin disorders for the elderly who visited the National Taiwan University in the last 7 years. Methods: Using a database from the Dermatology Outpatient Clinic of the National Taiwan University Hospital, 1993–1999 file, we conducted a retrospective cross-sectional study by evaluating the age, proportion, and gender of each specific cutaneous disease category, χ² tests were used for analyzing statistical significance. The analysis supplied odds ratios and 95% confidence intervals. Results: A total of 16,924 patients aged 65 years and older, which constituted 11% of the total patients seen at the Clinic of Dermatology from 1993 through 1999, were studied. The male to female ratio was 1.3 to 1. The most common cutaneous disorder in the elderly was dermatitis (58.7%), followed by fungal infections (38.0%), pruritus (14.2%), benign tumors (12.8%), and viral infections (12.3%). Cutaneous malignant tumors were found in 2.1%. Basal cell carcinoma occurred in 29.8%, actinic keratosis in 22.4%, Bowen’s disease in 13.3% and squamous cell carcinoma 13.3%. Interestingly, our cases of extramammary Paget’s disease showed a male predominance. Most melanomas were acral lentiginous melanoma located on the soles. The prevalence of common diseases in elderly patients compared with those outpatients of less than 65 years showed a 3-fold increased risk for pruritus. Moreover, the pattern of geriatric skin diseases in Taiwan was significantly different from Western countries. Conclusion: The prevalence of skin diseases in elderly patients emphasizes the importance of health education in geriatric people in Taiwan concerning appropriate use of emollients, proper foot care, sun protection and early detection of skin cancers.

“…The AsA population is very diverse, including individuals from many ethnic groups (Table I). The majority of information on cutaneous melanoma in Asians originates from Asia, with studies describing the incidence and development of cutaneous melanoma in Japan, Korea, China and Taiwan [19][20][21][22][23][24][25][26][27][28]. However, these studies are small with only 100-200 subjects.…”

“…5 The frequency of ALM, in countries with a predominantly white race, 7,8 varies between two and 8%, however in tropical and Asian countries, it can reach 72% of the cases of melanoma. 4,9,10,11 Approximately 60% of ALM occurs in the plantar surface and it is frequently diagnosed in the phase of thick primary lesion.1 2 It is important to keep in mind that this subtype occurs predominantly in the elderly, with a mean age around 60 years. 13 The majority of authors warn that due to all these characteristics, this type of melanoma tends to present a poor prognostic.…”

Resumo: FUNDAMENTOS-As características do melanoma acrolentiginoso (MAL) diagnosticado no Brasil são pouco estudadas. OBJETIVOS-Avaliar as características do MAL diagnosticado na Unidade de Melanoma da Santa Casa de São Paulo-UMSC, com-parando essa manifestação com outros subtipos e verificar se as possíveis diferenças entre eles teriam importância na deter-minação do diagnóstico, tratamento e prognóstico. MÉTODO-A casuística da UMSC foi subdividida em dois grupos, um de melanoma acrolentiginoso (MAL) e outro de melano-ma não acrolentiginoso (NAL), que foram comparados quanto a sexo, cor, idade, espessura e nível de invasão da lesão pri-mária, estadiamento, tempo decorrido entre a percepção do tumor e o atendimento pelo médico. RESULTADOS-A casuística correspondente ao MAL mostrou freqüência significativa de pacientes não brancos, com faixa etária mais elevada, com a lesão primária em média, mais espessa e ulcerada. Não ocorreram diferenças significativas quanto ao sexo e estadiamento, bem como com relação ao tempo decorrido entre perceber a neoplasia e procurar o médico. CONCLUSÕES-O MAL diagnosticado na UMSC ocorre, principalmente, em pacientes que normalmente não são alertados para câncer da pele (não brancos) e pertencem a uma faixa etária mais elevada (portanto, do ponto de vista teórico, poderiam estar menos atentos ao início da doença). A maioria apresentou lesão espessa e ulcerada, conseqüentemente de maior risco para metástases. Essa forma de câncer é desconhecida do público em geral e mesmo por boa parcela da classe médica. Palavras-chave: Diagnóstico; melanoma. Summary: BACKGROUND-The characteristics of acral lentiginous melanoma diagnosed in Brazil have been subject to few studies. OBJECTIVES-To evaluate the characteristics of acral lentiginous melanoma diagnosed at the Melanoma Unit of Santa Casa Hospital of Sao Paulo, to compare them with the other melanoma subtypes and to verify whether the possible differences between them are important in the determination of the diagnosis, treatment and prognosis. METHOD-Patients were divided into acral lentiginous melanoma and non-acral lentiginous melanoma groups and compared in reference to sex, color, age, depth and level of invasion of the primary lesion, stage, time between perceiving the tumor and seeking medical assistance. RESULTS-The cases of acral lentiginous melanoma were significantly more frequent among non-whites and the elderly, with the primary lesion, on average deeper and ulcerated, without significant differences in the sex, stage or the time elapsed between noticing the neoplasia and seeking the physician. CONCLUSIONS-Acral lentiginous melanoma diagnosed at the Melanoma Unit of Santa Casa Hospital of Sao Paulo, occurred mainly: in patients: who had not been advised about skin cancer (non-whites) and patients who are elderly and therefore , theoretically, could be less liable to notice the onset of the disease. The majority also presented deeper and ulcerated lesions and consequently with a higher risk of metastasis. This kind of cancer is u...
