Abstract:

Background.

Tumor of the follicular infundibulum is an uncommon benign neoplasm manifested histopathologically by a superficial epithelial plate-like growth pattern with multiple thin epidermal connections comprised of monomorphic cells with abundant cytoplasm. Cases of multiple tumors of the follicular infundibulum are rare and are described as hypopigmented scar-like macules or flat papules on the face, neck, and upper chest. Objective.

The objective was to describe a case of multiple tumors of the follicular infundibulum with numerous pigmented macules or papules and extensive involvement including the face, neck, anterior and posterior trunk, upper extremities, and intertriginous areas. Methods.

A case report and literature review are presented. Conclusion.

Tumor of the follicular infundibulum with its characteristic histopathologic manifestations is a well-recognized entity nowadays. Our case further expands the constellation of the clinical presentation of the multiple variant. Although the possibility of malignant basocellular degeneration seems remote, the multiplicity of the lesions, the possibility of clinical overlook, and the impracticality of complete treatment makes regular follow-up rational.
