Octreotide-LAR-associated erythema multiforme in an acromegalic subject: case report.

Long-acting somatostatin analogs are often used for treating acromegaly, either as adjuvant to surgery or radiotherapy or, more recently, as a primary therapeutic option. These drugs seem to be reasonably safe, but new adverse effects not yet described may occur during the use of the relatively new long-acting formulations. In this case report, we describe a severe cutaneous reaction (erythema multiforme) in a patient treated with long-acting release (LAR) octreotide, and also discuss the need of previous "testing" with short subcutaneous preparation of octreotide.
