Case Report

Cold subcutaneous abscess (CSA) is an abscess lacking classic inflammatory signs. This is a case of a 27-year-old incarcerated African American man who presented with 1-year history of soft, painless, mobile, masses on his limbs. Chest computed tomography scan showed diffuse reticulonodular infiltrates with right lower lobe mass. Computed tomography scan of the right upper extremity showed fluid density with no deep tissue involvement. Coccidioides complement fixation titers are 1:64, IgG 1.315, and IgM 0.242. Lung biopsy and CSA aspiration showed thick walled black spherules with endospores consistent with disseminated coccidioidomycosis (DCM). Cold subcutaneous abscess is a rarely reported manifestation of DCM. Defective cell-mediated immunity and inhibition of inflammation were thought to play a role in DCM and CSA pathogenesis. Cold subcutaneous abscess can remain unnoticed because of lack of inflammation. Our patient has longest time a CSA lasted without other symptoms of DCM. It is important to recognize it early to uncover a potentially dangerous disease.

Cold subcutaneous abscess (CSA) lacks classic inflammatory signs like erythema, warmth, and tenderness. The authors present a case of a 27-year-old incarcerated male who presented with acute fever and a 1-year history of small, mobile, non-tender masses on his extremities. He was later diagnosed with disseminated coccidioidomycosis (DCM) with lung and skin involvement. CSA is a rarely reported manifestation of DCM and can remain unnoticed. Early recognition is important to uncover a potentially dangerous disease.
