Stellate spontaneous pseudoscars (Colomb) represent a disorder of the senile skin, and are confined to the back of the hand and the radial and extensor aspects of the forearm. The clinical appearance is that of multiple, whitish, slightly depressed irregularly shaped, frequently linear, or star-shaped areas in an atrophic and irregularly pigmented skin. Episodes of senile purpura away from the pseudoscars are common. The histologic substrate consists of a plump, disc-shaped, fibrotic, and poorly vascularized mass which occupies the upper part of an atrophic and elastotic cutis. The whitish appearance is not due to lack of epidermal melanin but explained by the superficial location of the fibrous mass. A typical case is recorded. Asymmetry of the lesions in our patient is explained on the basis of occupational exposure to sunlight.
