Abstract:
Calcifying aponeurotic fibroma is a benign tumor with a predilection for distal parts of the extremities; it is very rare in the head and neck region. It commonly affects young patients-hence the term juvenile in the name. It is fibroblastic in origin and considered a cartilage analogue of fibromatosis, but its exact etiology remains unknown. Clinically, this tumor needs to be differentiated from fibromatosis, nodular fasciitis, chondroma, schwannoma, and rheumatoid nodule. A 24-year-old woman presented with swelling in the forehead for the previous 6 months. Wide surgical excision of the lesion was performed, and histopathologic examination revealed a calcifying aponeurotic fibroma. We reviewed the literature on this rare clinical entity and present our hypothesis on its etiology.

01:11Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
