Enlarged sebaceous gland size and increased number of lobule: sebaceous hyperplasia. However, the ability to express sebum from the central depression aids in distinguishing sebaceous hyperplasia from basal cell carcinoma. Histologically, the tumor exhibits a central cystically dilated cavity, lined by surface epithelium and containing keratinaceous debris and fragmented hair shafts (Fig. Various other special and immunostains have been trialed with varied results.

It may be difficult to differentiate between basal cell carcinoma and basaloid proliferation that arise in malformed hair germs in nevus sebaceous. Over the period of a 2-year study, sebaceous hyperplasia has the potential to progress to benign and malignant sebaceous cell neoplasms. There is also accompanying smoothing of the forehead surface texture. Associated with sun exposure, cyclosporine, etc. Sebaceous hyperplasia may be more prevalent in immunosuppressed patients: for example, in a patient following organ transplantation. Surgical options include a shave biopsy or punch biopsy for removal. The papules differ from milia, which are epidermal inclusion cysts, and are usually discrete, solitary, and whiter in color. Home Rhinophyma, in contrast with sebaceous hyperplasia, does not show multiple, enlarged sebaceous glands surrounding a single, dilated duct, but rather has multiple hair follicles with prominent sebaceous glands.

Lobules of sebocytes surround an invagination of epidermis that resembles the infundibulum of a hair follicle. Sebaceous adenoma differs from sebaceous hyperplasia by the presence of an increased number of basaloid cells and tumorous expansion of sebaceous lobules.
