The image shows a solitary, firm, asymptomatic, slowly growing nodule, developed subcutaneously on the upper lid margin.
The tumor is also called trichomatricoma, pilomatrixoma, pilomatricoma or Malherbe's calcifying epithelioma. The tumor is an uncommon benign cutaneous tumor, which takes the form of a slowly growing nodule. The pilomatricoma is more common in the first two decades of life.
The clinical diagnosis is often difficult, most cases being mistaken as sebaceous cysts. The treatment of choice is surgical excision. Incomplete surgical excision can be followed by local recurrence because most lesions are poorly defined.
