Interesting Presentation of Mycosis Fungoides in Staging on F-18 FDG PET/CT.

Mycosis fungoides is the major form of primary cutaneous T cell lymphoma. Its staging is based on the percentage of body surface involvement and biopsy-proven extra cutaneous nodal or visceral involvement. Literature shows F-18 FDG accumulation in disease-involved nodes and viscera with non-specific uptake due to co-existing inflammation limits its specificity. We report an interesting case of mycosis fungoides with bilateral upper limb edema and share its findings on F-18 FDG PET/CT.
