초록
After anaplastic large-cell lymphoma (ALCL) was first described by Stain in 1985, there have been several histological variants of ALCL reported. There are classified histological sub- types of ALCL, such as lymphohistiocytic, small cell, Hodgkin-like, composite pattern, and other less common variants including neutrophil-rich ALCL. A 63-year-old male patient presented with erythematous exophytic mass on the left lower leg. In the past, his condition had been diagnosed as abdominal primary cutaneous ALCL (pcALCL), which recurred as systemic ALCL (sALCL) in the left bronchus. After treatment, he achieved complete remis- sion. Histopathologic examination showed large-sized pleomorphic, anaplastic mitotic tumor cells, several neutrophils, and a few lymphocytes. Neutrophil-rich ALCL is a rare histological variant of ALCL. It is characterized by the presence of CD30-positive anaplastic tumor cells with numerous neutrophil infiltrations. Neutrophil-rich ALCL responds well to treatment but tends to recur. There were four cases reported to have recurrent neutrophil- rich ALCL. All cases were diagnosed with neutrophil-rich pcALCL prior to recurrence. Three cases had local recurrence, and only one case relapsed as sALCL. Herein, we present the first case of neutrophil-rich ALCL recurring as sALCL twice.
Abstract
After anaplastic large-cell lymphoma (ALCL) was first described by Stain in 1985, there have been several histological variants of ALCL reported. There are classified histological sub- types of ALCL, such as lymphohistiocytic, small cell, Hodgkin-like, composite pattern, and other less common variants including neutrophil-rich ALCL. A 63-year-old male patient presented with erythematous exophytic mass on the left lower leg. In the past, his condition had been diagnosed as abdominal primary cutaneous ALCL (pcALCL), which recurred as systemic ALCL (sALCL) in the left bronchus. After treatment, he achieved complete remis- sion. Histopathologic examination showed large-sized pleomorphic, anaplastic mitotic tumor cells, several neutrophils, and a few lymphocytes. Neutrophil-rich ALCL is a rare histological variant of ALCL. It is characterized by the presence of CD30-positive anaplastic tumor cells with numerous neutrophil infiltrations. Neutrophil-rich ALCL responds well to treatment but tends to recur. There were four cases reported to have recurrent neutrophil- rich ALCL.
