Abstract
- Purpose
We report a case of trichofolliculoma located in the medial canthal area that was initially clinically suspected to be basal cell carcinoma.
Case summary
A 93-year-old female patient presented to our hospital with a 1.2 × 1.4 cm mass in the right medial canthal area that had been present for 8 months. She had experienced continuous bleeding-like secretions during this time, leading to suspicion of basal cell carcinoma due to the absence of hair and a painless central ulcer lesion. Excision and biopsy were performed; the biopsy results revealed trichofolliculoma. The patient underwent complete resection and has remained recurrence-free for 6 months with regular follow-up observations.
Conclusions
Trichofolliculoma is a rare follicular hamartoma characterized by a nodule with dilated pores and dense hair in the center. Given its clinical similarity to benign and malignant tumors, such as basal cell carcinoma and squamous cell carcinoma, it is essential to differentiate this condition through excision and biopsy.
