A Case Report of Sebaceous Filaments

This case report describes a 16-year-old African American girl with a two-year history of white spicules on her face, diagnosed as sebaceous filaments. Histopathology confirmed the presence of cornified cells and calcification. Sebaceous filaments, caused by sebum accumulation and keratinocytes around hair follicles, are rare and likely under-reported. Treatment focuses on reducing sebaceous gland size to improve skin appearance. The patient was successfully treated with topical tretinoin, highlighting the importance of recognizing and managing this condition to enhance patients' quality of life.
