ABSTRACT
Abstract: We report an 80-year-old male patient with severe rheumatoid arthritis who was treated with tripterygium glycoside, an immunosuppressive agent made from the extract of a Chinese medicinal herb called Tripterygium wilfordii Hook F. The patient had no apparent skin lesions before the treatment, but he developed aggressive hyperkeratotic lesions with rapid progression after using tripterygium glycoside. He was repeatedly diagnosed with eczema, but treatment failed to achieve efficacy. Interestingly, a microscopic examination of the lesions revealed numerous scabies mites and eggs. Thus, we confirmed the diagnosis of Norwegian scabies infection. Treated with crotamiton 10% cream and 10% sulfur ointment for one month, the patient's clinical symptoms disappeared.

Pseudolymphomas or B‑cell lymphoma at the vaccination site have been reported by several authors. However, onset of cutaneous T‑cell lymphoma with cytotoxic features is a rare complication of vaccination. We report a 27‑year‑old man who developed a nodule and ulcer that arose at the site of injection of influenza vaccine. The neoplastic cells reacted positively for CD56, CD3, CD2, perforin, and granzyme B, but negatively for CD4, CD8, CD10, CD19, CD30, CD34, CD79, and betaF1. Molecular studies showed T‑cell receptor γ (TCR‑γ) chain monoclonal rearrangement. A diagnosis of peripheral T‑cell lymphoma, not otherwise specified (NOS) was established. The patient had high fever, progressive liver dysfunction and a rapid fatal evolution.
