BACKGROUND: The global prevalence of premalignant lesions has been continuously increasing in recent years, but there has been little research regarding the distribution and incidence of cutaneous premalignant lesions in Korean populations. OBJECTIVE: We conducted this retrospective study to analyze recent trends in the incidence and clinical patterns of cutaneous premalignant lesions in the Korean population. METHODS: We reviewed 1,292 cases (3,651 lesions) of patients with cutaneous premalignant lesions, including actinic keratosis (AK) and Bowen's disease (BD), from the Department of Dermatology at Dong-A University Hospital (January 1995 to December 2013). RESULTS: The average cutaneous premalignant lesion annual incidence was 1.82%, and the incidence continuously increased from 0.70% to 4.25% over the study period. The most common cutaneous premalignant lesion was AK (75.85%), followed by BD (24.15%). The mean age of onset was 68.76 years (men, 70.89 years; women, 65.56 years), and the male:female ratio of patients was 1:1.52. Major skin cancers, including squamous cell carcinoma (SCC, 8.90%), basal cell carcinoma (BCC, 6.42%), and malignant melanoma (MM, 0.70%), were detected in 15.79% of patients with cutaneous premalignant lesions. Three patients (0.23%) were previously diagnosed with both SCC and BCC. In addition, 59.13% of patients had a single lesion, while 40.87% had multiple lesions. Patient age, history of previous skin cancers, and occupation-related exposure to ultraviolet radiation were more common in patients with multiple lesions. CONCLUSION: Cutaneous premalignant lesion incidence has gradually increased in the Korean population.

Plasma levels of growth hormone(GH), luteinizing hormone(LH) and cortisol were determined by radioimmunoassay following radiofrequency(RF) stimulation or coagulation of various nuclei in thalamus and hypothalamus. RF stimulation or coagulation of many nuclei in thalamus and hypothalamus consisted of pulvinar and dorsomedial nucleus in thalamus and anterior and posterior hypothalamic nuclei in hypothalamus. Anterior thalamic stimulation resulted in highly significant increase of plasma LH, GH, cortisol and TH levels. However thalamic stimulation resulted no change in the level of various plasma hormones. Hypothalamic lesion produced significantly decreased plasma LH, GH and cortisol levels. Plasma cortisol and LH levels were highest 2 hours after stimulation while GH levels did not increased until 6 hours and TH until 72 hours respectively after stimulation. The significant difference in latency for beginning of hormone secretion suggests that GH, cortisol and LH may be controlled by several separate neuronal networks. Plasma GH and cortisol levels were lowest 72 hrs after coagulation of the anterior hypothalamic area, while GH, cortisol and LH levels did not change following stimulation or coagulation of posterior hypothalamic nucleus and thalamic nucldi. It was also noted that the anterior hypothalamic stimulation or coagulation caused increased or decreased in GH, cortisol, and LH than that observed from stimulation or coagulation of other hypothalamic and thalamic nuclei respectively.

Sternocostoclavicular hyperostosis is a benign ossifying diathetic disorder characterized by hyperostosis and soft tissue ossification of the clavicles, anterior portion of the first ribs, and manubrium, with variable hyperostosis or ankylosis in the spine and sacroiliac joints. A review of the literature and our own case describes the clinical findings and its characteristic features in RI, CT, and plain film.
