Case 7. (15 Dec. 1997)
Diagnosis: T-cell lymphoma (Mycosis Fungoides)
Brief discussion:
Mycosis fungoides is a T cell lymphoma that in its early
stage predominantly affects the skin in a manner that clinically resembles
eczema or psoriasis. A leukemic phase (Sezary's syndrome) can occur. Almost
every organ of the body can be invaded late in the course of the disease.
The most commonly affected organs are lymph nodes, liver, and lung. Approximately
50% of the patients have the pulmonary involvement. Radiologic findings
are multiple, bilateral parenchymal nodules, patchy areas of consolidation,
pleural effusion, and a diffuse reticulonodular pattern. Occasionally consolidation
can develope very rapidly and can simulate acute pneumonia.
