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.

Figure 4: The proportion of the premalignant skin lesions according to body location.

Mentions: In terms of anatomical distribution, 73.4% of premalignant and 63.2% of malignant skin lesions occurred on the head and neck area, followed by the trunk (15.2% vs. 20.1%) and extremities (11.5% vs. 16.7%) (Figs. 4, 5). Within the head and neck area, the cheek was the most prevalent site for the premalignant lesion to appear (46.2%), followed by the forehead (15.5%), nose (10.0%), periorbital area (9.0%), lower lip (6.0%) and so on (Fig. 6). Within the head and neck, the nose was most commonly affected by a malignant skin lesion followed by the cheek (21.0%), periorbital area (13.8%), scalp (13.2%), and forehead (8.0%) (Fig. 7). For the individual disease entity, 94.7% of AK developed on the head and neck area, mostly on the cheek (43.7%), followed by the nose (10.1%), forehead (15.0%), periorbital area (8.3%), lip (6.9%), ear (4.6%), chin (2.0%), and neck (1.1%). 75.8% of BDs occurred on the trunk and extremities, especially on the legs (20.2%), followed by the hands and fingers (8.1%), back (9.0%), arm (4.0%), abdomen (7.6%), chest (7.6%), buttock (4.5%), genitalia (10.8%) and anus (1.4%). Among malignant tumors, 91.2% of BCCs and 70.6% of SCCs developed on the head and neck area. For BCCs, the nose was the most prevalent site (34.6%), followed by the cheek (15.9%), periorbital area (17.0%), scalp (7.5%), forehead (6.8%), ears (4.7%), lip (1.9%), neck (1.6%), and chin (1.3%). In SCCs, the cheek was the most prevalent site (22.3%), followed by the scalp (9.3%), lip (9.9%), nose (7.1%), forehead (7.1%), ears (6.8%), chin (3.1%), periorbital area (2.5%), and neck (2.2%). Melanoma preferred the extremities (66.9%), especially the feet (24.0%), followed by the fingers (12.4%), legs (10.7%), toes (8.3%), arms (8.3%), and hands (3.3%).
