A Case of Digital Myxoid Cyst Coexisting with Epidermal Inclusion Cyst.
A 62-year-old male developed a solitary asymptomatic nodule on the lateral aspect of the distal interphalangeal joint of the right great toe. Histopathologic findings demonstrated a myxoid cyst with a concomitant epidermal inclusion cyst. To the best of our knowledge, this is the first case of concurrent occurrence of digital myxoid cyst and epidermal inclusion cyst. Although the exact mechanism for developing a digital myxoid cyst and an epidermal inclusion cyst simultaneously at the same site is not explained, trauma might be a possible cause.
