A 13-year-old girl presented with a 2-year history of progressive left ankle pain, limited range of motion, and swelling over the left lateral malleolus. Initial hematologic and rheumatologic lab tests were normal. MRI showed edema in the distal part of the left fibula. The patient was referred to our department due to inconsistencies in these findings. A 3-phase bone scan demonstrated increased activity in the distal physis of the left fibula, and SPECT/CT imaging indicated a possible osteoid osteoma. This diagnosis was confirmed through surgical resection and pathologic findings.

This case series and focused literature review address the diagnostic challenges and management strategies for patients presenting with atraumatic, isolated swelling, and stiffness of a single finger's proximal interphalangeal (PIP) joint. The dual emphasis is on synthesizing the lessons learned from our case series and providing a structured framework for clinical reasoning, including imaging, biopsy, and laboratory assessment. Non-traumatic causes of finger swelling may include rheumatological disease, atypical infection, tumor, or metabolic conditions.

Osteoid osteomas are benign, solitary bone-forming tumors associated with progressively worsening pain. The exact etiology remains unclear, although it is speculated to result from neoplasia, direct trauma, or an inflammatory process. We present a rare case of a 53-year-old male who presented to the ED with a one-year history of worsening right ear pain and no significant medical or surgical history.

Background: Osteoid osteoma is a benign bone tumor commonly affecting the lower extremities, typically the femur or tibia. However, its occurrence in the fifth metatarsal bone is rare, and atypical presentations can lead to delayed diagnosis and misinterpretation as other pathologies.
Case Presentation: We report the case of a 14-year-old Persian male athlete who presented with persistent lateral forefoot pain lasting 2 years, initially attributed to a traumatic injury.
