Non-melanoma skin cancer (NMSC) is one of the most common cutaneous malignancies, with an ever-increasing incidence rate worldwide [1]. Studies have shown an association between intermittent and chronic sunlight exposure and the development of BCC and SCC respectively [2]. UV radiation is a known carcinogen that can induce mutations in the p53 gene, known also as the guardian of the genome [3]. This can lead to persistent damage and failure to eliminate dysplastic cells as subsequent mechanisms like p21 and p16 activation fail to arrest cell cycle. Proapoptotic proteins such as BAK and BAX are also unable to activate programmed cell death, ultimately leading to the formation of precancerous lesions and NMSC [3, 4].

An 85-year-old Caucasian male presented to the clinic with multiple actinic keratoses alongside a suspicious tumour-like lesion on his head as well as a further lesion on his right lower leg. A thorough patient history revealed chronic sun exposure without adequate skin protection throughout his lifetime. The lesions were thought to appear 7-10 years prior and persisted to date. Patient reported no immunodeficiencies or genetic abnormalities. No other concomitant disease, medication or significant information was noted in the patient history. Upon examination the actinic keratoses were all over the mid-scalp, crown (Fig. 1a & 1b), preauricular (Fig. 1c) and periauricular (Fig. 1d) regions and were treated successfully with cryotherapy (Fig. 2f). The subsequent two lesions (Fig. 1f & 3a) were suspected for tumours and were treated surgically via elliptical excisions (Fig. 2a & 3a) without preliminary biopsies. The surgical excisions were made under local anaesthesia and performed with clear margins (Fig. 2b-2d & 3a-3c) Histopathology confirmed squamous cell carcinoma (SCC) in the scalp as well as basal cell carcinoma (BCC) in the right lower leg respectively. A further work up was conducted to assess cervical, occipital, axially and inguinal lymph nodes however no metastatic spread was detected. A postoperative 21-day follow up (Fig. 2f) revealed successful closure of wound edges and no further signs of neoplasm.

In the presenting case, it is evident the patient’s advanced age and chronic exposure of UV radiation has played a role in the development of premalignant actinic keratoses alongside the SCC lesion on his scalp.

There are number of known risk factors for developing multiple cutaneous neoplasms including hereditary disorders such as albinism or xeroderma pigmentosum [5-7]. Individuals with Xeroderma Pigmentosum (XP) are particularly susceptible to aggressive SCC of the scalp, in addition to other multiple neoplasms, due to the lack of DNA repair and photosensitivity [6, 7]. However, with XP and other hereditary conditions, the neoplastic lesions (with excessive sun exposure) present at a much younger age due to lack of innate protective mechanisms and accelerated development of the neoplasms [6,7]. Furthermore, the clinical presentation is incredibly severe in these cases due to the aggressive malignant transformation showing the significant risk hereditary conditions possess in the predisposition of skin cancers [5-7]. Our patient showed no signs of aggressive malignant growth with just two isolated synchronous lesions that exclude any hereditary cause.

Transplant recipients and patients with childhood and adolescent cancers have also an increased risk of developing multiple NMSCs [5, 8, 9]. This is mainly due to the stringent chemotherapeutic regimen that diminishes the immuno-protective mechanisms and allows for neoplastic growth [6, 9]. Ionizing radiation therapy is also shown to cause a six-fold increase in developing NMSCs later in life [9]. None of these factors were identified when questioning the patient.

It is evident in our case that the patient had no known comorbidities or other predisposing factors other than chronic sun exposure that could influence his current clinical profile. Neglect could be a possible cause of these simultaneous SCC and BCC lesions, suggested by the patient identifying them a decade prior to his visit to the clinic. This is commonly reported in patients with poor medical knowledge and perhaps the slow growth with prolonged phenotypic changes may not have caused much concern for the patient to seek medical care [10].

There is also data to suggest that there is an increased risk in developing a subsequent cancer after the initial primary NMSC [11]. Combining all these possible factors, we propose the
