Abstract

Piloleiomyoma is an uncommon benign neoplasm arising from the erector pilorum muscle. It presents as reddish-brown papules or nodules, in general located on the limbs or trunk, often painful. The present paper describes a case of piloleiomyoma with segmental distribution on left trunk, with an important expression of pain.

FIGURE 2
FIGURE 2
The photo shows mesenchymal spindle-cell neoplasm located in the dermis, composed of elongated cells of eosinophilic cytoplasm and ill-defined boundaries, spindle-shaped nucleus and blunt edges, forming multiple cell bundles with well-defined boundaries. (HE,40x)
FIGURE 3
FIGURE 3
Biggest increase details, revealing the neoplastic cells with fusiform nuclei and blunt edges. Note that there is no nuclear atypia. (HE, 100x).
FIGURE 4
FIGURE 4
Photo with Masson’s Trichrome (HE,100x): The special coloring allows to observe a good distinction of the neoplasia in red, compared to collagen bundles of dermis in green. Again, it is noted the characteristic of the tumor to form various neoplastic sets in the dermis
