Background: Epidermoid cysts are cutaneous cysts frequently observed among farmers, factory workers, carpenters, and tailors due to their occupations' predilection for repetitive minor hand trauma.
Case Presentation: A 66-year-old male laborer presented to our hospital with a swelling on the palmar aspect of his right middle finger. The swelling was accompanied by pain and an inability to work over the previous four months. A 2.5 cm × 2.5 cm smooth, tender, immobile, non-compressible hard swelling was detected just above the middle phalanx during the clinical examination on the volar aspect of the right middle finger. The diagnosis was confirmed by histopathology after excision. The patient's range of motion improved significantly following surgery, and his pain subsided.
Conclusion: We present a novel location for an epidermal inclusion cyst and the importance of histopathologic evaluation in this case. Additionally, we emphasize the significance of extensively checking the cyst's epithelium to guarantee complete capsule removal and rule out any additional pathology.
