Ganglion Cyst at the Lateral Aspect of the First Metatarsophalangeal Joint: Dermatological Management With Punch Biopsy Excision.

Ganglion cysts are prevalent benign lesions originating from joint capsules or tendon sheaths, predominantly found in the wrist, while their presence on the toes is extremely rare. We report the case of a 27-year-old female who presented with a painless, mobile, rubbery nodule on the lateral aspect of the first metatarsal of the right foot. Generally, ganglion cysts in the foot are uncommon, and their development is thought to be associated with repetitive mechanical stress, leading to mucoid degeneration of collagen tissue. While conservative treatments such as aspiration and steroid injections exist, they have a high recurrence rate, making surgical excision the preferred option. This case highlights an unusual presentation of a ganglion cyst on the lateral aspect of the first metatarsal and emphasizes the importance of considering mechanical stress as a contributing factor. Punch biopsy excision provided a definitive, minimally invasive, and effective treatment, demonstrating excellent results with no recurrence noted during follow-up.
