A benign skin tumor characterized by pleomorphic fibroblasts
Pleomorphic Fibroma[edit]
A pleomorphic fibroma is a rare, benign skin tumor that is characterized by the presence of pleomorphic fibroblasts. These tumors are typically found in the dermis and are composed of spindle-shaped cells with varying nuclear sizes and shapes.
Clinical Presentation[edit]
Pleomorphic fibromas usually present as solitary, slow-growing nodules on the skin. They are most commonly found on the head and neck region, but can also occur on the trunk and extremities. The lesions are typically asymptomatic, but some patients may experience mild itching or tenderness.
Histopathology[edit]
Under the microscope, pleomorphic fibromas are characterized by a proliferation of spindle-shaped fibroblasts with marked nuclear pleomorphism. Despite the atypical appearance of the cells, these tumors are benign and do not show mitotic activity or necrosis. The stroma is usually collagenous and may contain scattered histiocytes and mast cells.
Diagnosis[edit]
The diagnosis of pleomorphic fibroma is primarily based on histological examination. A biopsy of the lesion is performed, and the tissue is examined under a microscope to confirm the presence of pleomorphic fibroblasts and to rule out other skin neoplasms.
Treatment[edit]
The treatment of choice for pleomorphic fibroma is surgical excision. Complete removal of the tumor is usually curative, and recurrence is rare. Due to the benign nature of the tumor, additional treatments such as radiation therapy or chemotherapy are not required.
Prognosis[edit]
The prognosis for patients with pleomorphic fibroma is excellent. These tumors are benign and do not metastasize. Once excised, they typically do not recur, and patients can expect a full recovery.
