Interferon-induced cutaneous sarcoidosis in melanoma.
Interferon-induced cutaneous sarcoidosis in the adjuvant treatment of melanoma is a rare side effect. We present the case of a patient who developed two histologically confirmed subcutaneous sarcoid nodules 15 months after starting adjuvant therapy with interferon for lymph node metastatic melanoma in which the primary tumor was not known. The extension study, coinciding with occurrence of the nodules, showed no systemic sarcoidosis. This therefore represents the second reported case of interferon-induced cutaneous sarcoidosis in melanoma therapy. As computed axial tomography-PET or other imaging techniques are unable to differentiate between the radiological signs of melanoma metastasis and sarcoidosis, histological evaluation of the granulomatous lesions is essential with a view to avoiding unnecessary treatments.
