Bottom Line: Between 1991 and 1998, the incidence of cutaneous premalignancy was 0.10% which doubled during 1999-2006.For cutaneous malignancy, the incidence was 0.25% during 1991-1998 and 0.34% in 1999-2006.Incidence of AK among the new outpatients was 0.07% in 1991-1998 which staggered up to 0.15% in 1999-2006.

ABSTRACT
We evaluated the recent trend in the incidence of premalignant and malignant skin lesions between 1991 and 2006. Among 571,057 newly registered dermatology out-patients from our 8 affiliated university hospitals, 2,598 were diagnosed with a premalignant (899, 0.16%) or malignant skin lesions (1,699, 0.30%). Of 899 premalignant cases, 71.2% were actinic keratosis (AK), and 24.6% were Bowen's disease. Of 1,699 malignant cases, 46.2% were basal cell carcinoma, followed by squamous cell carcinoma (19.1%) and melanoma (7.1%). This 16-yr survey was divided equally into two time periods to compare the incidence of premalignant and malignant skin lesions at different time settings. Between 1991 and 1998, the incidence of cutaneous premalignancy was 0.10% which doubled during 1999-2006. For cutaneous malignancy, the incidence was 0.25% during 1991-1998 and 0.34% in 1999-2006. Incidence of AK among the new outpatients was 0.07% in 1991-1998 which staggered up to 0.15% in 1999-2006. These findings show an increase of both premalignant and malignant skin lesions, AK in particular in the dermatology outpatient-based incidence.

Mentions: Among 571,057 newly registered outpatients (1991-2006) from the 8 affiliated university hospitals, 2,598 were diagnosed with either premalignant (899, 0.16%) or malignant skin lesions (1,699, 0.30%). We divided the 16-yr study period into two equal intervals (1991-1998 and 1999-2006) to compare the incidence of premalignant and malignant skin lesions among dermatology outpatients over time. The incidence of cutaneous premalignancies rose from 0.10% to 0.20% while that of malignant skin lesions rose from 0.25% to 0.34%. As for the individual disease entity, the incidence of AK among the dermatology outpatients was 0.11% (1991-2006), 0.07% (1991-1998) and 0.15% (1999-2006), respectively. The incidence of BD was 0.04% (1991-2006), 0.03% (1991-1998) and 0.05% (1999-2006). The overall incidence of BCC was 0.14% with 0.12% in the former 8 yr and 0.15% in the latter 8 yr. The incidence for SCC were 0.06% (1991-2006), 0.05% (1991-1998) and 0.06% (1999-2006), and for melanoma, 0.02% (1991-2006), 0.02% (1991-1998) and 0.03% (1999-2006) (Table 1, Fig. 1). The proportion of each of the major premalignant (AK, BD) and malignant skin lesion (BCC, SCC, melanoma) out of the respective premalignant and malignant cases were presented in Figs. 2, 3, over the whole 16 yr as well as the two consecutive 8 yr periods.
