Abstract

Introduction

Cutaneous oncology, the branch of oncology dedicated to the study and management of skin cancer, addresses one of the most prevalent and treatable forms of cancer worldwide. Skin cancer encompasses a spectrum of malignancies arising from the skin's various cell types, including basal cells, squamous cells, and melanocytes. With rising incidence rates and diverse clinical presentations, understanding cutaneous oncology is paramount for early detection, accurate diagnosis, and effective treatment. In this article, we explore the landscape of cutaneous oncology, shedding light on its epidemiology, risk factors, diagnostic modalities, and therapeutic approaches [1].

Epidemiology and risk factors

Skin cancer represents the most common cancer globally, with incidence rates continuing to rise due to factors such as increased sun exposure, aging populations, and changes in lifestyle behaviors. The three primary types of skin cancer include basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma, each with distinct etiological factors and clinical characteristics. Ultraviolet (UV) radiation exposure remains the primary risk factor for skin cancer development, although genetic predispositions, immunosuppression, environmental exposures, and personal history of skin cancer or precancerous lesions also contribute to disease pathogenesis [2].

Types of cutaneous oncology

Basal Cell Carcinoma (BCC): BCC is the most common form of skin cancer, typically arising from basal cells in the epidermis or hair follicles. It commonly presents as a pearly or waxy nodule with telangiectasias, ulceration, or crusting. While BCC rarely metastasizes, it can cause significant local tissue destruction if left untreated [3].

Squamous Cell Carcinoma (SCC): SCC arises from keratinocytes in the epidermis and often develops in areas of chronic sun exposure or pre-existing skin lesions. It may appear as a firm, red nodule, scaly patch, or ulcerated plaque, with the potential for local invasion and metastasis, particularly in high-risk subtypes [4].

Melanoma: Melanoma originates from melanocytes, the pigment-producing cells in the skin, and represents the most aggressive form of skin cancer. It typically presents as an asymmetrical, multicolored lesion with irregular borders and evolving morphology. Melanoma carries a significant risk of metastasis to regional lymph nodes and distant organs if not detected and treated early [5].

Diagnostic modalities

The diagnosis of cutaneous oncology relies on a combination of clinical examination, dermoscopy, histopathological evaluation, and molecular testing [6]. Dermatologists and oncologists utilize dermoscopy, a non-invasive imaging technique, to visualize characteristic morphological features of skin lesions and distinguish benign from malignant lesions. Skin biopsies, including shave biopsies, punch biopsies, and excisional biopsies, provide histopathological confirmation of the diagnosis and help determine tumor subtype, depth of invasion, and margin status. Molecular testing, such as BRAF mutation analysis and gene expression profiling, may inform prognosis and guide targeted therapies in select cases of advanced melanoma [7].

Treatment strategies

Treatment options for cutaneous oncology vary depending on tumor type, stage, location, and patient factors. Localized lesions may be managed with surgical excision, cryotherapy, electrodessication and curettage, or topical therapies such as imiquimod and 5-fluorouracil [8]. Mohs micrographic surgery, a precise tissue-sparing technique, is commonly employed for high-risk or cosmetically sensitive lesions to achieve optimal oncologic outcomes while minimizing tissue loss [9]. Advanced or metastatic disease may require systemic therapies, including immunotherapy, targeted therapy, chemotherapy, and radiation therapy, administered alone or in combination based on tumor molecular profiling and clinical trial data [10].

Conclusion

Cutaneous oncology encompasses a diverse array of skin cancers, each with unique etiological factors, clinical presentations, and treatment considerations. Through multidisciplinary collaboration among dermatologists, oncologists, pathologists, and other healthcare professionals, we can advance our understanding of cutaneous oncology and improve patient outcomes through early detection, personalized treatment approaches, and ongoing research endeavors. By promoting sun-safe behaviors, raising awareness of skin cancer risk factors, and advocating for regular skin examinations, we strive to reduce the burden of cutaneous malignancies and enhance the quality of life for individuals affected by these diseases.
