Seborrheic keratosis is a benign lesion that is common in the trunk
and head and neck regions. It shows a considerable variety of
histological appearances leading to different variants. The presence
of sebaceous differentiation in seborrheic keratosis is very rare
and can histologically mimic benign and malignant tumors with
sebaceous differentiation. We present a case of a 65-year-old male
presenting with multiple nodules over the right and left sides of neck
and the right preauricular region, histopathological examination
of which revealed multiple pigmented seborrheic keratoses with
sebaceous differentiation. This case is reported for its rare sebaceous
differentiation and multiplicity along with the importance of
differentiating it from a variety of benign to malignant neoplasms
showing sebaceous differentiation.
