A novel case of reactive perforating collagenosis in a patient with cutaneous infiltration of Epstein–Barr virus-positive angioimmunoblastic T-cell lymphoma

Reactive perforating collagenosis (RPC) is a cutaneous disorder that has rarely been associated with haematological malignancies. We present the case of a 47-year-old man with a 6-month history of Epstein–Barr virus-positive angioimmunoblastic T-cell lymphoma (AITL) who was undergoing chemotherapy and had an extremely pruritic, papular eruption that had worsened over the past 7 months. Skin biopsy findings revealed RPC. He was treated with triamcinolone cream and hydroxyzine alongside his chemotherapy; this resolved his symptoms. This patient’s case offers a unique clinicopathological presentation of RPC in the setting of AITL in the skin and demonstrates the importance of a dermatologist's management of cutaneous disorders in patients with cancer to improve their quality of life.
