High-resolution computed tomography findings of diffuse pulmonary involvement by mycosis fungoides.
The authors describe a case of diffuse pulmonary involvement by mycosis fungoides in a 55-year-old man who presented with progressive exertional dyspnea. Although he had a long history of skin lesions, mycosis fungoides remained undiagnosed at initial presentation. High-resolution computed tomography revealed hazy ground-glass opacities along the thickened bronchovascular bundles and interlobular septa, particularly in the mid and upper lung fields, and traction bronchiectasis in the central regions. Skin biopsy confirmed the diagnosis of mycosis fungoides in the plaque stage. Transbronchial lung biopsy revealed diffuse infiltration of the atypical lymphoid cells in the peribronchial and perivascular regions. In this case, high-resolution computed tomography played an important role for suggesting the lymphoproliferative disease in this patient with undiagnosed mycosis fungoides.
