This clinicopathologic study concerns 62 patients with one of the Dupuytren type fibromatoses. Of the 62 patients, 42 had the lesion in the palm (palmar fibromatosis), 12 in the sole (plantar fibromatosis), 2 in the penis (penile fibromatosis), and 6 in the ectopic locations, the dorsal aspect of the hand in 3 patients, the dorsum of the fingers in 2, and the forearm in 1. The clinically palpable nodules were histologically classified into those of the following three phases, according to Luck's classification: 12 proliferative phase (27), involutional phase (23), and residual phase (12). In addition to fibroblastic proliferation, the lesion of the proliferative phase exhibited vascular features consisting of one or more layers of cells with oval nuclei around the vessels within the nodule. In the lesions of the late proliferative and involutional phase, the intracytoplasmic fine filaments were visible in cells compatible with myofibroblasts by Masson's trichrome stain. The nuclei of the elemental fibroblasts in the same phases were often crossed transversely by one or more fine basophilic lines.
