Introduction

Cutaneous and subcutaneous lesions are common and can be benign or malignant. Benign lesions do not carry any significant harm, but malignant lesions are serious and can lead to life-threatening diseases such as cancer. Therefore, understanding the malignancy potential of cutaneous and subcutaneous lesions is important to help diagnose and treat these lesions effectively. 12 Cutaneous and subcutaneous tumors may originate from epithelial, mesenchymal, or melanocytic tissues, and the potential for malignancy varies for each type. For instance, malignant melanomas are more common in melanocytic lesions, while other skin cancers like basal cell or squamous cell carcinoma commonly originate from epithelial tissues. Therefore, a proper diagnosis is significant to determine the origin of the lesion, and the risk of malignancy.3

Malignancy Potential of Cutaneous and Subcutaneous Lesions

As a health care professional, it is crucial to understand that not all cutaneous and subcutaneous lesions are cancerous, but some can become malignant over time. This includes melanoma, which can arise from moles or other pigmented spots on the skin. Other types of skin cancer like basal cell carcinoma and squamous cell carcinoma can also originate from skin lesions. Consequently, early detection through regular medical evaluation is crucial to prevent these conditions from becoming life-threatening. Any new or altering skin lesion should be assessed by a medical professional to determine if it may pose a potential risk of developing into cancerous growths.13 It is important for health care practitioners to educate patients on the importance of preventative care measures, including routine screenings to detect such lesions at their earliest stage when treatment has better outcomes, leading to successful treatment and improved quality of life.

Several factors can influence the malignancy potential of a cutaneous or subcutaneous lesion. One of the major determinants of malignancy is the location of the lesion, as this may affect its behavior and spread. For instance, lesions on the palm of the hands, soles of the feet, and genital areas are more prone to malignant transformation than lesions in other parts of the body.3 Another essential factor in determining the malignancy potential of a cutaneous or subcutaneous lesion is the pattern of growth or change in the lesion over time. Regular checkups and monitoring of the lesion are crucial to identify any changes such as irregular borders, variability in color, or rapid growth that might indicate malignancy. Histology is also important in understanding the malignancy potential of cutaneous and subcutaneous lesions. A biopsy of the lesion can provide a detailed understanding of the lesion's cellular makeup, which can indicate the likelihood of malignancy.456

The aim of this study is to investigate the potential malignancy of cutaneous and subcutaneous lesions. Specifically, we will examine the histopathological features of these lesions to determine their likelihood of developing into cancerous growths. By understanding the malignancy potential of these lesions, we hope to improve early detection and treatment of skin cancer, ultimately leading to better patient outcomes. This study will contribute to the growing body of knowledge on skin cancer and provide valuable insights for clinicians and researchers alike.

Materials and Methods

This study was conducted in accordance with the principles outlined in the current Helsinki Declaration. The primary objective was to investigate the incidence and correlation of malignancy among patients who underwent excision for cutaneous and subcutaneous lesions over a 10-year period. The study cohort consisted of individuals who presented with such lesions and underwent excision. Comprehensive demographic data, pathology, and surgical reports, as well as follow-up information, were meticulously recorded for all participants. Patients diagnosed with malignancy based on histopathological examination comprised the study group, while those without malignancy formed the control group.

Through meticulous analysis and robust statistical methodologies, the study aimed to identify any significant disparities in characteristics and outcomes between the study group and the control group. Key factors such as age, gender, lesion size, location, and histopathological features were systematically compared between the two groups to identify potential risk factors for malignancy. Furthermore, long-term follow-up data were scrutinized to evaluate recurrence rates and overall survival among patients in both groups. The findings of this investigation hold promise in providing valuable insights into the management and prognosis of individuals undergoing excision for cutaneous and subcutaneous lesions, thereby informing clinical decision-making and improving patient outcomes.

Statistical Analysis

Statistical analysis of numerical variables was conducted using SPSS (Statistical Package for the Social Sciences) version 23 software (IBM Corporation, Armonk, New York, United States). Categorical variables were expressed as frequency and percentage, while normally distributed parametric data were presented as mean (standard deviation), and non-normally distributed parametric data were presented as median (quartile range) with the range of values. Parametric data comparisons were performed using the student's t-test, while categorical data comparisons utilized Fisher's exact test. Statistical significance was determined by a p-value less than 0.05 at a 95% confidence interval.

Results

In our study, a total of 9,202 excision procedures were performed on 8,962 patients over the specified duration. The most prevalent lesions encountered were epidermal/tricholemmal cysts and lipomas, constituting 34.5 and 21.8% of cases, respectively. Among the total cohort, malignancy was identified in 104 patients, representing a prevalence of 1.1%. Table 1 presents a comprehensive breakdown of the various diagnoses observed among the cases examined.

The average age of patients with malignancy was 60.3 (± 16.2) years, with 60 being males and 44 females. Interestingly, patients diagnosed with malignancy were significantly older than those without malignancy (59.9 ± 14.7 vs. 44.3 ± 14.4 years, respectively, p < 0.001). However, no statistically significant difference was observed in terms of gender distribution (p = 0.353). The most prevalent histological types identified among patients with malignancy included carcinoma, sarcoma, lymphoma, and malignant melanoma. Additionally, 10 patients necessitated supplementary surgical intervention following the pathology results. Those diagnosed with malignancy were subsequently referred to the oncology department for further follow-up and additional treatments.

Discussion

Cutaneous and subcutaneous lesions encompass a spectrum of abnormal growths or changes in the skin and underlying tissue, manifesting in diverse forms such as lumps, bumps, or patches. 1 These lesions arise from various etiologies, including genetic predispositions, environmental factors, and lifestyle influences. 2 Diagnostic imaging modalities like ultrasound play a crucial role in evaluating superficial lesions, particularly those not amenable to assessment via computed tomography. 4

Diverse Etiologies and Treatment Approaches

These lesions can arise from both benign and malignant origins, with common benign growths including skin tags and lipomas, alongside potentially malignant entities like skin cancer.1 Surgical interventions such as shave/curettage or excision and closure represent primary treatment modalities for these lesions.56 However, neglecting timely intervention may engender risks and complications, spanning delayed wound healing to metastatic cancer dissemination.678 Hence, prompt medical evaluation and intervention are imperative for suspicious lesions.

Emphasizing Early Detection and Intervention

The study underscores the critical imperative of early detection and intervention for cutaneous and subcutaneous lesions. While many lesions are benign, the potential for malignancy necessitates vigilant medical attention and proactive management. 78 Noteworthy symptoms indicative of concern include the emergence of new lesions, alterations in existing lesions, and associated pain or pruritus. 9 Imaging techniques like magnetic resonance imaging (MRI) and ultrasound aid in lesion assessment, often necessitating biopsy for definitive diagnosis.4

Navigating Treatment Options

Early detection facilitates an array of treatment options tailored to lesion characteristics, ranging from surgical excision to adjunctive therapies like radiation or chemotherapy. Careful consideration of lesion type, location, and patient factors guides treatment decisions, ensuring optimal outcomes while minimizing unnecessary interventions. Accessible outpatient surgical procedures under health care provisions like the Affordable Care Act enhance treatment accessibility and affordability for affected individuals.9
