Abstract
Benign histiocytofibroma (HFB) is one of the most common benign
tumors, most commonly occurring in the lower limbs of adults,
mostly women. It is often a small lesion, however there are
atypical (HFB). Deep soft tissue and certain organs can also be
affected. It mainly develops in the subcutaneous tissue. We report
a case of and study its anatomo-clinical and dermoscopic aspect of
this entity

Case Report
Observation: It is a 34-year-old patient, without notable
pathological ATCD, who presents for 1 and a half years, a brown
lesion, on the anterior aspect of the left leg non-painful non
pruriginous, gradually increasing in size becoming in relief but
functional signs. On clinical examination, we have note a nodule of
1 cm of erythematous mole consistency in places and pigmented by
others, well limited, with regular contours, base not infiltrated,
resting on healthy skin (Figure 1). The dermoscopic examination, in
turn, objectified interspersed shiny white linear structures
achieving a grid appearance, with the visualization of vessels in
points at its crossed structures (Figure 2). The biopsy exeresis of
the lesion objectified, a spindle cell population, a fasciculate
and storiform architecture with polymorphonuclear cells,
eosinophils and lymphocytes. In favor of a histiocytofibroma
(Figure 3).
A benign dermatofibroma or histiocytofibroma is a firm papular
or nodular lesion, most often small, reddish-brown in color,
fibrohistiocytic in nature. They most often sit on the thighs or
legs but they can sit anywhere. The is often clinical. The lesions
are sometimes biopsied to exclude melanocytic
proliferation or other tumors. In histology, we find spindle
cells of small fibroblastic or pseudohistiocytic type with slightly
angular nuclei are arranged in short crisscrossed bundles,
accompanied by some histiocytes or multinucleated giant cells and a
variable number of inflammatory cells [1].
The most common pattern associated with dermatofibroma is the
classic dermoscopic pattern (pigment network and central white
patch) [1]. The particularity of our observation is the dermoscopic
description, not reported.
