Abstract:
Fibro-osseous pseudotumor of digits (FOPD) is an uncommon histological diagnosis. Clinical and imaging findings may resemble high-grade sarcoma or infection. We describe a patient with progressive pain and swelling at the dorsal surface of the first web space. MRI and CT imaging revealed an intramuscular heterogenous soft tissue mass defined by a mineralized peripheral ring. Core needle biopsy diagnosed FOPD. Eight months later a matured ossified nodule that was quite smaller than the initial soft tissue mass was excised. The patient is symptom free without local recurrence at 1 year follow up. Soft tissue masses of the hand pose a challenging diagnostic and therapeutic issue. An in depth interpretation of clinical, imaging and histology findings is important to avoid erroneous diagnosis and treatment.

Muscles of the Forearm that Move the Hand and Fingers
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
