Subcutaneous panniculitis-like T-cell lymphoma - An elusive case presenting as lipomembranous panniculitis and a review of 72 cases in the literature

We present a remarkable case of subcutaneous panniculitic T-cell lymphoma ( SPTL) that eluded diagnosis for 14 years and illustrates the importance of continued follow-up with repeat biopsy when SPTL is suspected. This case is unusual in that multiple biopsies demonstrated either a nonspecific pannic ulitis or lipomembranous panniculitis with calcified lipomembranes. A clini copathologic review of 72 cases of SPTL from the English language literatur e is also presented, and approaches to diagnosis and treatment are reviewed .
