Benign metastasizing mesothelial cells in an axillary lymph node secondary to a chest wall fibromatosis

A 19-year-old female presented with a mass on the right side of the chest of less than 1 year’s duration. She underwent a right chest wall excision followed by a chest wall reconstruction. Macroscopic examination of the excised tumour showed a 175 · 160 · 125 mm sized dumbbell-shaped mass with a small anterior chest wall component and a larger subpleural component. The tumour on slicing showed a fleshy, creamish pink, glistening cut surface with a few small cystic spaces predominantly in the subpleural component (Figure 1A). Dissection of the lateral aspect of the specimen revealed two lymph nodes, one of which had multiple pale white areas distributed around its periphery. The patient was last seen 6 months post surgery and at that time was well and without evidence of local or systemic disease.
