Introduction: Cutaneous metastases represent 2% of skin tumors, with an overall incidence of 5.3%. Although rare, clinical presentations of cutaneous metastasis vary and can be mistaken for benign and malignant skin conditions.
Methodology: This was a descriptive, retrospective review of all patients diagnosed with cutaneous metastasis seen at the Department of Dermatology from January 2013 to December 2019. Clinical and histopathologic data from the patients were collated from medical records, and slides were retrieved for review.
Results: A total of 115 patients were included and 122 slides reviewed. There were more female than males, the mean age was 52.3 ± 14.0 years of age. The most common primary cancer was the breast, and accordingly, the most common location was anterior chest. Among the 122 slides reviewed from 104 patients, the most common histologic type was adenocarcinoma (72.1%), and showed the infiltrative pattern (26.2%). Other histologic types seen were melanoma (13.1%), leukemic infiltrates (11.5%), squamous origin (2.5%), and epithelioid sarcoma (0.8%). Lymphovascular invasion and dermal sclerosis were observed. Immunohistochemical stains were performed in only 13.9% of the cases. There was a high concurrence of the clinical with the histopathologic diagnosis (95.6%).
Conclusion: Although rare, patients with cutaneous metastasis may present in dermatology clinics. Knowledge of clinical features and low threshold for doing biopsies may prove useful for these patients. Similarly, dermatopathologists should be able to recognize histologic features of cutaneous metastasis morphologically. Histologic features may be subtle and may be reminiscent of benign inflammatory conditions, hence judicious use of immunohistochemical staining is recommended.

Cutaneous melanoma is one of the most aggressive skin cancers originating from skin pigment cells. Patients with advanced melanoma suffer a poor prognosis and generally cannot benefit well from surgical resection and chemo/target therapy due to metastasis and drug resistance. Thus, adoptive cell therapy (ACT), employing immune cells with specific tumor-recognizing receptors, has emerged as a promising therapeutic approach to display on-tumor toxicity.

Adenoid cystic carcinoma (ACC) is a rare head and neck cancer; even more infrequently, it presents as a primary lesion at other sites. Due to ACC's usual pattern of perineural and perivascular spread, it often manifests in delayed local recurrence and distant metastases. Metastasis to the kidney is very rare with as few as 15 cases reported in the literature.

BRCA1-associated protein 1 (BAP1) is a tumor suppressor gene that was first identified in 1998. Germline loss of functional variants in BAP1 is associated with a tumor predisposition syndrome with at least four cancers; uveal melanoma (UM), malignant mesothelioma (MMe), renal cell carcinoma (RCC), and cutaneous melanoma (CM). Furthermore, somatic BAP1 mutations are important drivers for several cancers most notably UM, MMe, RCC, intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC).

VACCIMEL is a therapeutic cancer vaccine composed of four irradiated allogeneic human melanoma cell lines rationally selected to cover a wide range of melanoma tumor-associated antigens (TAA). We previously demonstrated that vaccination in the adjuvant setting prolonged the distant-metastasis-free survival of cutaneous melanoma patients and that T cells reactive to TAA and the patient's private neoantigens increased during treatment. However, immune responses directed to vaccine antigens that may arise from VACCIMEL's somatic mutations and human polymorphisms remain unexplored.

High-risk cutaneous squamous cell carcinoma (hr-cSCC) tumors exhibit aggressive behavior, leading to local recurrence, metastasis, and mortality. The management of hr-cSCC tumors is not well-defined. To clarify the impact of clinical risk factors and management strategies on disease-related outcomes (DROs) in patients with hr-cSCCs.
