Subcutaneous lymphoid hyperplasia arising at site of ethnic scarifications and mimicking subcutaneous panniculitis-like T-cell lymphoma.
The case of a 40-year-old black man, who developed a very unusual tumour-like lymphoid hyperplasia involving primarily the subcutaneous tissue, is reported. The lesion, which arose at a site of tribal scarifications, displayed a deceptive morphology that closely resembled subcutaneous panniculitis-like T-cell lymphoma (SPTCL). An accurate diagnosis could only be made following detailed immunohistochemical and molecular studies. Although SPTCL has been thought to represent a very specific clinicopathologic entity, the present case illustrates that its histological appearance can, however, be closely mimicked by reactive and benign conditions.
