An 84-year-old male ex-farmer was admitted to the orthopaedic department due to an inflamed subcutaneous mass in his left palm over the heads of the 3rd and 4th metacarpal bones (). The lump was slightly tender on palpation without interfering with finger flexion. Mass was noticed 3 months before without trauma history and kept growing since then. Routine blood investigation was normal. Plain radiographs revealed a nonradiolucent object 5 × 2 mm in size, located in the region of the mass. A well-defined, avascular, mass was depicted in the MRI. Patient was scheduled to be operated for an excisional biopsy of a hand soft tissue tumor. Intraoperatively, a thick-wall cyst containing brown-colored fluid, a metallic object, and various particles resembling rusty products, was excised (). After describing our findings to the patient, he recalled a long-forgotten incidence during World War II, 75 years ago: a “superficial” gunshot injury in the palmar aspect of the wrist near its crease. Ricochet of a bullet caused a wound that was healed with no complication, leaving a hardly noticed scar. Histological examination of the excised mass confirmed our suspicion. The residual foreign body was a bullet which, being deposited subcutaneously in the palm of the hand for more than 70 years, had been subjected to excessive corrosion in the biological environment and progressively isolated in a granulomatous tissue capsule. The postoperative healing was uneventful. On the follow-up examinations at the 1st, 3rd, and 6th month, no sign of inflammation or recurrence has been noticed and hand function was unproblematic. Further follow-up was considered unnecessary.
