Benign fibrous histiocytoma of clavicle
The present case has been published in the Journal of Case Reports and Images in Orthopedics and Rheumatology.

Benign Fibrous Histiocytoma (BFH) occurs approximately, 1% of all benign bone tumors and mostly BFH occurs in the long bones where femur and tibia are most frequently involved. Clavicle is not the common site for all bone tumors and majority of the clavicular tumor has malignant characteristics. BFH of the clavicle is rare, therefore to rule out the diagnosis we need to increase the awareness among clinician and multidisciplinary discussion.

A 20-year-old male presented with chief complaint of mass in the right shoulder. Two years prior to admission, he had traffic accident and sustained right clavicle fracture. ORIF using plate and screw was carried out. 10 months prior to admission, he complained about cough but recovered after receiving treatment from pulmonologist. Four months later, the fracture had recovered and he underwent implant removal.

He began to feel painless growing mass in the former site of surgery one month before admission. From physical examination, a mass size 8x8x2 cm with regular border and tenderness was found in his right shoulder without range of motion limitation. Laboratory results were normal.

Plain radiograph suspected non union right clavicle. CT of the right shoulder revealed soft tissue nodule 5.8x5.6x3 cm with clavicle destruction. It grew expansively became 9x6x4 cm in 2 months. A FNAB was performed with a result of benign fibrous histiocytoma. Unfortunately, the patient refused all medical procedures offered in the outpatient clinic.
