Extensive Systemic Sarcoidosis with Testicular Involvement Mimicking Metastatic Testicular Cancer

Sarcoidosis is an idiopathic, multisystem disease that rarely involves the genitourinary tract. Here we present an unusual case of testicular sarcoidosis with extensive lymphadenopathy that mimicked a metastatic testicular tumor. A 27-year-old male presented with a palpable right testicular mass accompanied by multiple palpable inguinal lymph nodes. The scrotal ultrasound showed a hypoechoic le...

Certolizumab Pegol-Induced Folliculitis-Like Lichenoid Sarcoidosis in a Patient with Rheumatoid Arthritis

Anti-tumor necrosis factor α (TNF-α) biologic agents are used for treating refractory sarcoidosis. However, sarcoidosis-like epithelioid cell granulomas may develop during anti-TNF-α treatment. A 63-year-old man suffering from rheumatoid arthritis was treated with oral methotrexate and methylprednisolone for 4 years. He subsequently started biweekly subcutaneous injections of certolizumab pegol...

Topical Pimecrolimus as a New Optional Treatment in Cutaneous Sarcoidosis of Lichenoid Type

We report the case of cutaneous sarcoidosis of lichenoid type successfully treated with pimecrolimus. For the first time in the literature, we propose the use of this topical calcineurin inhibitor for the treatment of the cases refractory to common therapy regimens.
