R. Baran et al., CLINICAL AND HISTOLOGICAL PATTERNS OF DERMATOFIBROMAS OF THE NAIL APPARATUS, Clinical and experimental dermatology, 19(1), 1994, pp. 31-35
True fibromas develop as painless slow-growing nodular tumours. They m
ay appear in any portion of the nail apparatus. The clinical features
vary according to their anatomical site. In contrast, the histological
features, consisting of a dermal hypocellular reticular nodule with i
ll-defined demarcation, were similar in all our patients, and factor X
IIIa was negative.
