Seven patients remain on uninterrupted sirolimus. Of 12 patients who stopped therapy, seven have resumed due to recurrence of symptoms. All patients demonstrated reduction in LM bulk, ranging from modest to significant. All patients with mucosal vesicles (n\u2009=\u200914) resolved or improved on sirolimus.
