Superficial Acral Fibromyxoma

The patient is a 61 yo woman with a 1 - 2 month history of a nodule on the dorsum of the left foot.

O/E: 1 cm nodule without any diagnostic features.

Clinical Photos:





Pathology: (Microscopic photos courtesy of Jag Bhawan, Chief of Dermtopathology, Boston University Department of Dermatology)
The lesion was shave-excised and the base cauterized.  Pathology showed a nodular dermal lesion comprised of fibromyxoid stroma with stellate to spindle-shaped fibroblasts and traversed by prominent vascular channels. (Photomicrographs 2x, 4x, 10x, 20x, 40x)






Diagnosis:  Superficial Acral Fivbromyxoma

Discussion:  This is a rare lesion.  I am not sure if the diagnosis could have been made prior to pathology.  Most of these lesions are periungual  This one was not.  This case is being presented for interest since little is known about this kind of lesion.
