Abstract Skin metastases are rare and may occur in the context of a known metastatic disease or be the first clinical sign of an underlying primary tumor. In the case of carcinoid neoplasms, determining whether the cutaneous tumor is primary or secondary and identifying the tumor origin in metastatic cases is not always an easy task. This is the report of a case of cutaneous metastasis presenting as the first clinical manifestation of a previously unknown pulmonary carcinoid tumor, including the discussion of histopathological and immunohistochemical findings that allowed an adequate diagnosis of the tumor etiology and reinforces the importance for dermatologists and dermatopathologists to be familiar with these findings.

Abstract External ear melanoma is rare, and early diagnosis and treatment are paramount for the patient's survival. Four clinical cases are reported, emphasizing the importance of the routine clinical examination of the ears in the dermatological consultation. The study included male and female patients, aged 60 to 81 years old, with melanocytic lesions in the outer ear, evaluated with detailed physical and dermoscopic examination, leading to the identification of lesions suggestive of melanoma. The cases were treated surgically with excision of the lesion, and the diagnoses were confirmed by histopathological study. The therapeutic approach was instituted early as most cases were diagnosed at an early stage, which directly impacted global survival.
