A first time report on the coocurrence of sarcoidosis and ALK(-) CD30(+) anaplastic large cell lymphoma that is highly responsive to brentuximab vedotin treatment.

Sarcoidosis is known to be associated with higher incidence of solid tumors and hematological malignancies. ALK(-) CD30(+) anaplastic large cell lymphoma is a type of non-Hodgkin lymphoma showing poor prognosis, and seldom co-occurs with sarcoidosis. As this rare and highly mortal disease did not respond to classical chemotherapies and showed remission with brentuxumab vedontin treatment, we are presenting our first case reported from Turkey hoping to contribute to the literature.
