Introduction And Importance: The intratendinous ganglion cyst is an extremely rare entity. Thus, the global incidence has not been reported yet. The literature search showed scarce case reports and none has reported its occurrence in extensor indicis propius (EIP) tendon. The benign nature and the region at the dorsal hand mimic to the more common dorsal wrist ganglion. However, the surgical treatment arises significant risk to the function and may require subsequent tendon graft or tendon transfer.
Case Presentation: A 51-year-old-female presented with 4 years history of a slow-growing lump over the dorsal region of the right hand with discomfort during finger motions. The ultrasonography confirmed the diagnosis of dorsal wrist ganglion.
Clinical Discussion: Intraoperatively, unlike the common presentation which is the well encapsulated mass originating from the carpal joint, the mass was found within the EIP tendon sheath and infiltrate the tendon substance. Surgical debulking was done and left the tendon partially intact. The frayed part was trimmed to ensure a smooth gliding. On the 6 month follow up, patient was symptom-free without any recurrence.
Conclusion: The intratendinous growth of a ganglion must be identified preoperatively for a proper management plan and inform consent. The intratendinous ganglion cysts frequently weaken the tendon. Hence, surgical excision is necessary with the preparation of secondary tendon reconstruction.

Background: A synovial cyst is a herniation of synovial tissue through a joint capsule, often mistaken for a ganglion cyst. The key distinctions are that synovial cysts have a synovial cell lining, while a ganglion cyst is delineated by dense fibrous connective tissue. Typically found near joints, synovial cysts are associated with conditions like osteoarthritis, prevalent in females aged 20 to 50.

Synovial or ganglion cysts are the most common soft tissue tumors of the wrist and hand and can arise from joints or tendons. Intratendinous synovial cysts, in contrast, are rare and their pathogenesis is still a matter of debate. The treatment of synovial cysts of articular origin using arthroscopy is commonly used with good results.

An intratendinous ganglion cyst is a very rare benign lesion with an unknown etiology. The clinical diagnosis can be difficult as patients may have mild symptoms or impaired hand functionality. Ultrasound and magnetic resonance imaging can differentiate a ganglion cyst from other soft-tissue tumors and tumor-like lesions and provide excellent information on the location of an intratendinous lesion to schedule surgical treatment.

Ganglion cysts in the knee region can manifest as anterior knee pain. Unlike synovial cysts, these lesions lack synovial epithelial lining and occur secondary to mucoid degeneration of connective tissue because, often in response to chronic irritation and repetitive traumas. However, an intratendinous location is a rare finding.
