A Rare Case of Neglected Giant Basal Cell Carcinoma in a Nurse-Case Report and Literature Review

Basal cell carcinoma (BCC) is the most common skin cancer in the fair-skinned adult population over 50 years of age and the incidence is rising. Generally, BCC has an indolent course, low mortality and a good prognosis due to low rates of metastasis. Giant basal cell carcinoma is a rare reported oncological entity which accounts for 0.5% to 1% of all cases of BCC and has a diameter larger than 5cm. Basosquamous carcinoma is a rare high-risk type of BCC with clinical and histopathological features of both BCC and squamous cell carcinoma. A 61-year-old female presented to our clinic for a giant bleeding tumor located under her left breast. She initially noted the tumor almost 15 years ago. Although the patient was a nurse, she was afraid to seek medical advice until an episode of significant bleeding. At presentation the tumor was a 15/7cm in size, was invading the underlying structures and had a central ulceration. The margins of the tumoral plaque had several nodules and pearly structures suggesting the possible clinical diagnosis of BCC.
