In this study we aimed to understand and summarize the clinical and pathological characteristics of cutaneous mixed tumors. A retrospective analysis was conducted on the clinical and pathological data of 20 patients diagnosed with cutaneous mixed tumors in our outpatient department between January 2014 and April 2024. The study comprised 20 patients with a male-to-female ratio of 3:2. The mean age of onset was 52.10 ± 15.46 years. All patients presented with solitary cutaneous lesions ranging from 2 to 30 mm in diameter. Notably, none of the patients received a preoperative diagnosis of cutaneous mixed tumor. The clinical manifestations of cutaneous mixed tumors are nonspecific, necessitating histopathological examination for a definitive diagnosis.

Cutaneous squamomelanocytic tumor (SMT) is a very rare cutaneous malignancy, composed of a dual phenotypic population of both malignant melanocytes and keratinocytes, intimately intermingled together. Herein, we report a new case of a SMT occurring in an 82-year-old man, located on the scalp. Histopathology revealed a mixed population consisting of squamous cell carcinoma and melanoma within the same lesion, also confirmed using immunohistochemical staining for high molecular-weight cytokeratins (HMWCKs) and Melan-A.
