History

Poromas typically are asymptomatic, slow-growing, or stable nodular lesions. [11] Although most are asymptomatic, pain can be a presenting sign. Poromas are one of many types of benign adnexal neoplasms that can manifest secondarily within a nevus sebaceus. [12, 13]

Physical Examination

Poromas typically manifest as skin-colored papules or nodules smaller than 2 cm in diameter. [14] Poromas may occasionally manifest as pigmented lesions. [15] Protuberant lesions may exhibit surface erosion or ulceration. Rarely, a poroma manifests in association with nevus sebaceus as a secondary neoplasm. [12, 13] Rabady et al reported a poroma arising on the eyelid. [16] See the image below.
