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.
