Background: Ultraviolet (UV) radiation is known to be an important etiologic agent in the development of skin cancer. Keratoacanthoma is an unusual, well-described cutaneous neoplasm that resembes squamous cell carcinoma but spontaneously resolves. Rarely, multiple keratoacanthomas may develop. Objective We present a case of multiple keratoacanthomas in a patient with psoriasis who had received UVB phototherapy. These lesions were hyperkeratotic papules, many of which spontaneously resolved and demonstrated the histologic characteristics of keratoacanthoma. Conclusion: We believe that UV radiation is the most likely etiologic factor in this patient's development of multiple keratoacanthomas. We wish to bring to the attention of clinicians this unusual adverse effect of UV treatment.

Background: Skin cancer is a broad term that refers to a variety of different types of cancer. It is usually recognized as non-melanoma and melanoma skin cancer. In many parts of the world, the prevalence is high, with significant ecological and ethical variation. Objectives: Objective was to determine demographic and histological features of skin cancer in Southwest region of Pakistan. Methodology: This retrospective study was carried out on skin cancer 1169 cases of Centre for Nuclear Medicine and Radiotherapy (CENAR) in Quetta. The data from January 2000 to December 2009 (10Years) was retrieved from record. The aim was to determine the importance of skin cancer in this area, its gender wise distribution and its pathological types. Results: Record of total 9308 cancer patients was retrieved from patients presenting to CENAR Quetta. From 9308 case, 1169(12.5%) patients were of skin cancer which was second most prevalent category of cancer in this area. Prevalence was higher in males with 713(61%) cases as compared to females. Pathologically with 634(54%) cases, the most prevalent category was Squamous cell carcinoma (SCC). Conclusion: Skin cancer is wide-spread type of cancer in patients of south-west region of Pakistan. The findings of this study are not aligned with published data. The difference is because of high altitude of the study area, dry climate and long skin exposure particularly in low socio-economic field workers.

Introduction: A periodical database is important including for skin cancer. Periodical registration is needed to acknowledge changes in pattern and frequencies of skin lesion. Objective: The purpose of this study was to describe the pattern and the frequency of skin lesion in RSUD Kariadi.Method: A cross-sectional study was conducted through analysis of the medical records of patients diagnosed skin lesion in the pathology labolatory of RSUD Kariadi between 2008 and 2009. The variables were secondary data including age, gender, specimen area, dan histopathology diagnosis. Data was choosen by consecutive sampling from 381 medical records of skin tissues examined at laboratorium of pathology anatomy of Dr. Kariadi general hospital during 2008-2009.Result: 381 cases were recorded comprising of 246 (65%) neoplastic and 135 (35%) non neoplastic lesion. 120 patients presented with skin cancer, and 126 with benign skin lesion. Most malignancy was observed among female patients (62.5%) on age catagory of 15-39 (65%). The most common lesion was basal cell carcinoma (48.3%) followed by squamous cell carcinoma (33.3%), malignant melanoma (10%), skin appendix carcinoma (2.5%), other malignancies (4.9%).Conclusion: the most common malignancies in Dr. Kariadi general hospital before 2008 was similar to data from 13 laboratory of pathology anatomy in Indonesia, which is squamous cell carcinoma.

Cutaneous squamous cell carcinoma is the second most common form of skin cancer and accounts for 20% of cutaneous malignancies. We report the case of a patient who presented with a complaint of nonhealing wounds following radiation therapy for the treatment of noninvasive squamous cell carcinoma of both lower extremities. Initial biopsies of the wounds were benign. However, a second biopsy performed approximately 2 months later was found to be positive for invasive squamous cell carcinoma. This case uniquely exemplifies that all nonhealing wounds should be viewed with a critical eye for possible malignancy even in the presence of previous negative biopsy. This is especially true for radiation wounds that may be prone to malignant transformation or recurrence. (J Am Podiatr Med Assoc 101(4): 360–362, 2011)

Chemoprevention is a relatively novel and promising approach for controlling cancer that uses specific natural products or synthetic agents to suppress, reverse, or prevent premalignancy before transformation into invasive cancer. Oral cavity squamous cell carcinoma (OCSCC) represents a large, worldwide health burden with approximately 274,000 cases diagnosed annually worldwide. Smoking and alcohol consumption are major inducers of OCSCC. Recently, the human papilloma virus was also shown to potentially be an etiologic factor. Due to its easily identifiable risk factors and the presence of premalignant regions, oral cancer makes a good candidate for chemoprevention. Green tea is the most widely consumed beverage in the world, and it has received considerable attention because of its abundant, scientifically proven, beneficial effects on human health. In this review, we discuss the role of green tea in oral cancer chemoprevention with regard to the multiple molecular mechanisms proposed in various in vitro, in vivo, and clinical trials.

Squamous cell carcinoma of the skin (SCCS) is a common malignancy with potentially devastating consequences in patients with locally advanced or metastatic disease. Its rising incidence, primarily a result of an aging population and increased ultraviolet (UV) radiation exposure, characterize an emerging unmet need. A firm understanding of the biology of this disease, likely distinct from that of other squamous malignancies because of the influence of UV radiation, is necessary in the evaluation of treatment paradigms. Careful recognition of high-risk features pertaining to tumor and host characteristics is paramount to proper management. However, a lack of standardization in guidelines in this regard creates a challenge for physicians. Questions persist regarding additional evaluation and treatment for advanced disease such as the roles for sentinel lymph node biopsy and the adjuvant use of radiation and chemotherapy. With respect to advanced disease, multiple combinations of chemotherapy have been tested with variable success, but no rigorous randomized studies have been conducted. In addition, EGFR inhibitors such as cetuximab and erlotinib have displayed antitumor activity and as such, warrant further investigation. In sum, the treatment of locally advanced and metastatic SCCS is a ripe area for clinical investigation. This article summarizes the current understanding of disease biology and emerging questions in the management of this disease.
