Superficial acral fibromyxoma (SAFM) is a rare, benign, slow-growing fibroblastic tumour of the soft tissue that is part of the group of myxoid soft-tissue neoplasms. It is a rare entity and usually occurs in the acral regions. We report the case of a 64-year-old man who presented to the emergency room for a lesion expected to have occurred as a result of an ingrown toenail. Because this patient had a history of repeated recurrences despite multiple surgical wedge excisions, we performed a complete surgical excision, and the pathological analysis confirmed the suspected diagnosis of SAFM. There was no recurrence at the 6-month follow-up. This case highlights the fact that this tumour is still misunderstood and underrecognized by surgeons and this often leads to delayed diagnosis. Although it is a rare entity, clinicians should be aware of this tumour in cases of recurring ingrown toenails.
Background
Meniscoid lesions have been reported in patients with chronic ankle injuries, especially in soccer athletes, and such lesions cause soft-tissue impingement and pain. To our knowledge, we are the first to report a meniscoid lesion in the ankle joint presenting as a long-term sequela of avascular necrosis of the talus that developed in childhood.
Case presentation
In this paper, we describe a 55-year-old Caucasian male patient who presented with a 1-year history of intermittent locking, “giving way,” weight-bearing pain, and swelling over the anterior aspect of the ankle joint. Imaging showed a rare case of avascular necrosis of the talus associated with an unstable plica-like lesion that was removed arthroscopically after unsuccessful conservative treatment.
Conclusion
We demonstrate that unstable meniscoid lesions of the ankle joint can be treated successfully with arthroscopic debridement. We obtained satisfactory short-term clinical results at the 2-year follow-up, even though advanced osteoarthritis was present.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
