“…EPC may arise de novo or can originate from malignant transformation of an EP [2]. An EP that shows changes, as sudden growth, ulceration and spontaneous bleeding turns on the red flag for an arising EPC.…”

“…In the histopathological examination the usual findings include nuclear atypia, increased mitotic activity rate and necrosis. In the clinical examination, infiltrated borders, bleeding, growth and ulceration are important features that may indicate malignancy in EP-like lesions [2].…”

“…Since EPC shares multiple features with other tumors and is a rare skin neoplasm, diagnosis is a challenge. Anatomopathological signs of invasion and cellular pleomorphism in an eccrine tumor are clues to the definitive diagnosis [2]. Treatment is necessary due to the aggressive nature of the tumor, and surgery is the first option.…”

“…EPC may develop as a primary tumor or from a benign long-standing EP with malignant transformation. Dermoscopy is used increasingly to facilitate clinical diagnosis [2]. In this report, we describe a case of an invasive EPC originating in an eccrine poroma and associated with an adjacent satellite lesion of eccrine poroma.…”

Pigmented lesions are a frequent challenge for dermatologists, due the difficulty of differential diagnosis between common entities in clinical practice, such as seborrhoeic keratosis, basal cell carcinoma, melanocytic lesions and adnexal tumours. A thorough history and physical examination, always accompanied by dermoscopy, are essential.We report here 2 cases of middle-aged patients, who were otherwise healthy, with solitary acquired pigmented lesions, who were referred to our dermatology department in order to rule out malignant melanoma. Case 1. A 55-year-old man presented with an excrescent, dark-brown lesion, 13 mm in diameter located on his right shoulder. Dermoscopy revealed irregular polymorphous vascularity, blue-grey ovoid nests, and keratinization. The patient reported that the lesion had grown in the last years. The lesion was excised and sent to the pathology department (Fig. 1). Case 2. A 65-year-old woman with a firm, slow-growing, black nodule, 15 mm largest diameter, located on the inner side of her left thigh was referred to our unit. Dermoscopy revealed blue-grey pigmentation, globule-like structures, comedo-like structures, irregular vascularity and keratinization. The lesion was removed and sent for histology (Fig. 2).
