Mastocytosis – Solitary Mastocytoma

July 19th, 2014

Solitary Mastocytoma is a benign skin lesion that I occasionally encounter in both my The Woodlands dermatology and Conroe dermatology offices.  Clinically, Solitary Mastocytoma appears as a single lesion that is usually smaller than 1cm with a smooth surface and a red/brown color.  They most commonly occur in children.  The most common anatomic location is the hand and wrist.  Due to the presence of mast cells in a Solitary Mastocytoma, blistering or whelping occurs when the lesion is rubbed.  Occasionally, patients may experience systemic symptoms such as flushing from a solitary mastocytoma.  Most Solitary Mastocytomas do not require treatment as they resolve spontaneously with time.  In cases where the Solitary Mastocytoma is problematic, surgical excision can be performed.
