A 40-year-old man presented with asymptomatic, multiple, variable-sized, erythematous umblicated papules on the trunk and both extremities for 4 months. The patient was diagnosed with Hodgkin’s lymphoma (stage IIA) and underwent chemotherapy after histopathologic examination of a neck mass that occurred a month ago. A punch biopsy was performed on his right lower leg. Histologic examination showed transepidermal elimination of degenerated collagen. Masson-Trichrome stain discriminate collagen fibers from muscular tissue as bluish coloration crossing from dermis through the epidermis. The diagnosis of acquired reactive perforating collagenosis was made clinically and histopathologically. The skin lesions showed much improvement with chemotherapy. Acquired perforating disorders represent a group of cutaneous disorders that occur in adult who often has chronic kidney disease or diabetes mellitus.Cases of acquired perforating disorders associated with Hodgkin's lymphoma have been rarely reported in English literature. To our knowledge, this is the first case of acquired reactive perforating collagenosis in Hodgkin’s lymphoma in Korea. Herein, we report a case of acquired reactive perforating collagenosis in Hodgkin’s lymphoma
