case_images: A 47-year-old man was admitted to our department with a soft nodular mass at the plantar surface of the forefoot (figure 1).
case_images: Magnetic resonance imaging (MRI) revealed a well-defined mass located at the plantar forefoot with no apparent bone infiltration.

case_images: Magnetic resonance imaging (MRI) revealed a well-defined mass located at the plantar forefoot with no apparent bone infiltration, (figure 2).
case_images: The sagittal T1-weighted image. A lobulated, encapsulated, fatty mass with multiple hypointense nodules and septa in the subcutaneous layer of the forefoot, underneath the plantar aponeurosis.

case_images: T1-weighted image revealed a lobulated, encapsulated, fatty mass (signal intensity identical to subcutaneous fat) with multiple hypointense nodules and septa in the subcutaneous layer of the forefoot, underneath the plantar aponeurosis, (figure 3). The corresponding sagittal T1-weighted contrast enhanced image, revealed that the non-fatty component does not show any apparent enhancement, (figure 4).

case_images: T1-weighted image revealed a lobulated, encapsulated, fatty mass (signal intensity identical to subcutaneous fat) with multiple hypointense nodules and septa in the subcutaneous layer of the forefoot, underneath the plantar aponeurosis, (figure 3). The corresponding sagittal T1-weighted contrast enhanced image, revealed that the non-fatty component does not show any apparent enhancement, (figure 4).
case_images: The coronal STIR image through the phalanges. It showed signal suppression of the fatty component and high intensity of the non-fatty component.

case_images: Finally the coronal STIR image through the phalanges showed signal suppression of the fatty component and high intensity of the non-fatty component, (figure 5).
case_images: The nodule was excised via a plantar approach using a longitudinal incision dictated by the morphology of the corn.

case_images: The nodule was excised via a plantar approach using a longitudinal incision dictated by the morphology of the corn (figure 6).
case_images: The mass was multilobular having a vascular pedicle which was cauterized.
