Abstract
Introduction and importance
Pilomatrixoma is a superficial benign skin tumor that originates from the matrix cells of the hair follicles. It presents more frequently during the first two decades of life and usually involves the head and neck, most often in the eyelid or eyebrow area.
Case presentation
We present a case of pilomatrixoma, which appeared at the age of 14 years with history of recurrent inflammation and discharge mimicking a ruptured epidermal cyst.
Discussion
Pilomatrixomas are often confused clinically with other benign masses, encountered in the clinical practice more frequently like dermoid cysts and epidermal inclusion cysts. The rate of accurate preoperative diagnosis ranges between 0%–30% and the correct diagnosis can be established only after excision and histopathological examination. Our case demonstrates an atypical presentation of pilomatrixoma as an epidermal inclusion cyst.
Conclusion
Ophthalmologists and ocular pathologists should be aware of the atypical presentation of pilomatrixomas to ensure early accurate diagnosis and curative treatment.
Pilomatrixoma is a benign skin tumor with typical histopathological appearance.
Pilomatrixoma is often confused clinically with an epidermal cyst.
Accurate diagnosis and complete excision of pilomatrixoma is essential.
Our case demonstrates the pitfall in diagnosing pilomatrixoma.
