Peripheral T-cell Lymphoma, Not Otherwise Specified: An Unusual Presentation of a Rare Lymphoma.

We present a case of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) masquerading as a skin rash which progressively worsened over a year. After being treated for various dermatologic and infectious etiologies, he did not feel any relief and presented to our hospital. Imaging showed generalized lymphadenopathy. Later, lymph node biopsy and skin biopsy confirmed the diagnosis of CD30 + peripheral T-cell lymphoma. He was soon started on chemotherapy with cyclophosphamide, doxorubicin, etoposide, vincristine, and prednisone (CHOEP). However, because of the aggressive nature of his disease and advanced stage at presentation, he succumbed to complications and died of sepsis.  This case highlights the importance of considering a rash as one of the early symptoms of an underlying life-threatening disease.
