The clinical diagnosis was an infected epidermal cyst and the lesion was drained in the general surgery department. Despite follow-up care over a month, the wound did not heal and the patient was referred to us for evaluation. Physical examination showed an erythematous-violaceous indurated plaque with a 5-cm diameter on the upper outer quadrant of the right buttock (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). The plaque, which was hard on palpation, contained an ulcer measuring 15<span class="elsevierStyleHsp" style=""></span>mm at its widest diameter secondary to the surgical drainage. The central area of the ulcer was very deep and its walls contained a solid yellowish-white material. When questioned, the patient reported that she had lost 15<span class="elsevierStyleHsp" style=""></span>kg in 2 months, a loss that she attributed to a naturopathic diet. We examined the lesion by ultrasound and performed a wedge biopsy for histologic and microbiologic studies. The fungal, bacterial, and mycobacterial cultures were all negative. Color Doppler imaging on a MyLabClass <span class="elsevierStyleSmallCaps">C</span> machine (Esaote) equipped with an 18-MHz probe revealed a heterogeneous solid-cystic lesion measuring 45<span class="elsevierStyleHsp" style=""></span>×<span class="elsevierStyleHsp" style=""></span>27<span class="elsevierStyleHsp" style=""></span>mm in the dermis and extending into the subcutaneous tissue. The lesion also had anechoic central areas admixed with hyperechoic areas with well-defined borders (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>). It displayed posterior reinforcement and Power Doppler imaging showed peripheral vascular poles. The above findings (the heterogeneity and significant vascularity at several poles of the lesion) suggested malignancy, which allowed us to request a rush histology study. Histologic examination showed infiltration of the dermis by a malignant epithelial proliferation of cells with a squamous pattern of growth, marked nuclear pleomorphism, prominent nucleoli, and several mitotic figures; the proliferation formed solid nests with evident intercellular bridges and apoptotic cells (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a> A and B). There was also extensive necrosis and no signs of connection with the epidermis. The proliferation extended as far as the peripheral and deep borders of the biopsy specimen. With a diagnosis of poorly differentiated squamous cell carcinoma, we requested a chest radiograph, which showed a nodule in the left lung and a focal interstitial infiltrate containing septal lines and images of nodules in the right lung. Positron emission-tomography-computed tomography confirmed the presence of a disseminated stage <span class="elsevierStyleSmallCaps">IV</span> lung tumor with a large pulmonary mass in the right upper lobe and multiple lung and bone metastases. The study also showed a hypermetabolic soft tissue mass corresponding to the skin lesion on the right buttock. The patient opted to have the lesion completely excised. She was enrolled in a palliative care clinical trial by the oncology department, but died 7 months later.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><elsevierMultimedia ident="fig0015"></elsevierMultimedia><p id="par0010" class="elsevierStylePara elsevierViewall">The skin is a rare site of metastasis from internal malignancies and is estimated to be involved in 0.5% to 9% of all cases.<a class="elsevierStyleCrossRefs" href="#bib0055"><span class="elsevierStyleSup">1–4</span></a> All types of malignant tumors can produce cutaneous metastasis, but the type most likely to do this varies considerably from one series to the next.<a class="elsevierStyleCrossRefs" href="#bib0065"><span class="elsevierStyleSup">3–6</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">Cutaneous metastases from lung tumors are rare (0%-4% depending on the series) and are associated with a very poor prognosis as the mean survival is just 3 to 5 months.<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">7</span></a> Few cases have been reported in the literature.<a class="elsevierStyleCrossRefs" href="#bib0080"><span class="elsevierStyleSup">6–8</span></a> The clinical presentation of cutaneous metastases is highly variable and includes macules, papules, nodules, and ulcerated lesions.
