A unique case of subcutaneous panniculitis-like T-cell lymphoma presenting as an abscess following an arthropod bite

We present an exceptional case of SPTCL masquerading as a solitary abscess which developed following an antecedent arthropod bite. Unique histological features encountered include foci of neutrophilic aggregation and admixed eosinophils within the neoplastic lymphomatous subcuticular infiltrate. As SPTCL rarely presents as an abscess, the authors wish to highlight this diagnostic pitfall and suggest excluding SPTCL as a cause of pseudo-pyoderma in patients who are afebrile with a discordant inflammatory marker profile. In addition, this condition should be suspected in non-diabetic patients who experience a rapid clinical course with suppuration and demonstrate a poor response to appropriate antibiotics.
