“…[4,5] It is radiologically described as a spherical single tumor, with a diameter of less than 1.5 cm, exhibiting a core zone of atypical bone known as the “nidus.” [6] Although a computed tomography (CT) scan is thought to be the most precise imaging modality for diagnosing OO, [5] magnetic resonance imaging (MRI) is considered more sensitive than a CT scan in phalanx OOs.

“…[1] It primarily affects men (male-to-female ratio, 2:1) and manifests in children and young adults. [2] First described in 1935 by Jaffe HL, it is characterized by a reactive bone border surrounding an osteoid-rich core with varying degrees of calcification. [3] The first and most frequently observed symptom of OO is localized pain associated with fusiform swelling.…”

“…[6] Although a computed tomography (CT) scan is thought to be the most precise imaging modality for diagnosing OO, [5] magnetic resonance imaging (MRI) is considered more sensitive than a CT scan in phalanx OOs. [2] The pathological features of OO are a small, round, soft, and hyperemic tumor surrounded by a harder and more sclerotic reactive bone. Microscopically, the nidus comprises a tissue of immature osteoid (woven bone) trabeculae with active osteoblastic rimming.…”

“…[7,8] Approximately 50% of OO cases occur in the lower extremities (thigh and tibia), and only 5% to 10% occur in the hand and wrist. [2,5] Involvement of the phalanx is a rare occurrence, with most instances documented in individual case reports. Delayed diagnosis and treatment are not uncommon because of the rare location and the unusual symptoms associated with it.…”

Rationale: Osteoid osteoma is a relatively common benign bone-forming lesion that often occurs in young adults with a predilection for the lower limbs and spine. It is characterized by the formation of osteoid tissue, a precursor to bone, and can cause pain and restricted mobility in affected areas. Osteoid osteoma of the hand and fingers is rare, thus representing a diagnostic challenge. A written informed consent was provided from the patient’s father for the publication and sharing all images and clinical data concerning the patient. Patient concerns: We are reporting a case of an 11-year-old girl who presented with persistent pain and swelling in her left index finger, as well as limited mobility, over the course of 1 year. Nonsteroidal anti-inflammatory drugs eased the pain, but it resurfaced once the medication was discontinued. Diagnoses: A series of investigations, showed a lytic lesion at the second proximal phalangeal neck, with features indicative of osteoid osteoma. Interventions: Excision with bone grafting was performed as definitive therapy with pathological confirmation of the osteoid osteoma diagnosis. Nevertheless, the patient returned 2 years later with a recurrence of her previous symptoms, and further tests suggested a recurrence of osteoid osteoma. To address the recurrence, a modified open thermoablation technique was used. Thermoablation is a minimally invasive procedure that uses heat to destroy the tumor cells, and it has been shown to be effective in treating osteoid osteoma. The modified open approach involves making a small incision to access the tumor and delivering heat directly through a previously CT-guided inserted Kirschner wire to the affected area. Outcomes: The patient reported no pain at 1 month and 1 year after the surgery, with no radiological signs of recurrence, indicating complete excision of the lesion. Lessons: Overall, this case highlights the challenges of diagnosing and treating osteoid osteoma in the hands and fingers. Further research is needed to better understand the underlying causes, potential risk factors, and optimal treatment for osteoid osteoma recurrence.
