Case 81


Click on the images above to zoom in

A 32-year-old female patient, otherwise healthy, sought for medical assistance due to a fast growing lesion on her right forehead. She reported that a “pimple” had previously arisen on the same region and that she had squeezed it. Since then, the resulting lesion had been presenting recurrent ulceration, easily bleeding and progressive growth.

Based on the clinical history and photograph presented herein, which is the most likely diagnosis?

a) Amelanotic melanoma


b) Spitz nevus


c) Pyogenic granuloma


d) Botryomycosis



- The pyogenic granuloma is a benign vascular tumor of the skin or mucous membranes characterized by rapid growth and  a friable surface, which usually bleeds after minor trauma.

- The underlying etiology remains unknown, although some predisposing factors have been suggested, such as trauma, hormonal influences, growth factors and medications.

- It may occur at any age; however, incidence peaks in the second and third decades of life.

- Diagnosis is predominantly based on clinical features, even though histologic confirmation is always recommended.

- Choice of treatment hinges on many factors, such as size and location of the lesion.
