The case study involves a 52-year-old Irish American male named K.B., who presents with a skin lesion described as a changing, dark-colored mole with irregular borders, a scaly surface, and a size of approximately 0.2 cm. The primary diagnosis in this case is melanoma, a malignant type of skin tumor known for its potential to metastasize if not diagnosed and treated early. The patient's history of outdoor work, frequent visits to tanning beds during adolescence, and a longstanding lesion exhibiting irregular borders and color changes all strongly support this diagnosis. The physical examination confirmed features characteristic of melanoma, such as asymmetry, border irregularity, multiple colors, and evolution over time, which are key ABCDE criteria used in skin cancer assessment.

Three differential diagnoses to consider include seborrheic keratosis, basal cell carcinoma, and dysplastic melanocytic nevus. Seborrheic keratosis typically presents as a benign, waxy, "stuck-on" lesion with a uniform color and well-defined border, usually not changing in size or color (Menzies et al., 2020). Basal cell carcinoma, the most common skin cancer, often appears as a pearly or translucent papule with telangiectasia and may ulcerate, but it typically occurs on sun-exposed areas and lacks the pigmentation described in the lesion (Berkowitz et al., 2019). Dysplastic nevi are atypical moles that can resemble early melanoma but are usually larger, with irregular borders and multiple colors; however, they tend not to change rapidly over a short period (Nevus Committee, 2021). Both history and physical exam findings, such as recent changes in the mole's appearance, shape, and border, are instrumental in differentiating melanoma from benign lesions and other skin conditions.

The patient's history of significant sun exposure, especially during formative years, and his use of tanning beds, are significant risk factors for melanoma development (American Academy of Dermatology Association, 2022). The physical exam findings—irregular border, color variation, and recent change—are suggestive of melanoma, necessitating further diagnostic and treatment planning.

Potential treatment options for melanoma include surgical excision with appropriate margins, which remains the gold standard for early-stage disease (Crawford et al., 2020). For localized melanoma, wide local excision followed by sentinel lymph node biopsy if indicated helps assess metastasis. For advanced or metastatic melanoma, systemic therapies such as immune checkpoint inhibitors (nivolumab, pembrolizumab) or targeted therapies targeting BRAF mutations (dabrafenib and trametinib) are available and have shown significant efficacy (Larkin et al., 2019). Additionally, ongoing surveillance and patient education regarding sun protection and skin self-examinations are vital components of management.

In conclusion, early detection of melanoma greatly improves prognosis, emphasizing the importance of thorough patient history, physical examination, and biopsy for definitive diagnosis. The case underscores the necessity of clinicians maintaining a high index of suspicion for suspicious pigmented lesions in individuals with significant sun exposure histories and using evidence-based interventions to optimize patient outcomes.
