BACKGROUND Atrophic dermatofibroma is an uncommon variant of dermatofibroma. It lacks the classic clinical features of a dermatofibroma and is often misdiagnosed. OBJECTIVE To describe the clinical and histologic features of atrophic dermatofibroma. METHODS Case report and review of the literature. RESULTS A 45-year-old white woman was found to have a 7 mm x 5 mm atrophic, depressed lesio...

Aneurysmal benign fibrous histiocytoma is an uncommon pathologic variant of dermatofibroma. In addition to the features of a typical dermatofibroma, it has large cleft-like or cavernous blood-filled spaces with numerous hemosiderin pigments. It should be differentiated from angiomatoid malignant fibrous histiocytoma, malignant melanoma, and vascular tumors such as Kaposi's sarcoma and angiosarc...

Dermatofibroma, also known as benign fibrous histiocytoma, is a soft-tissue tumour that usually occurs in the mid-adult life and shows a slight female predominance. Giant dermatofibroma, a very rare clinical variant, is characterised by its unusually large size, benign biological behaviour despite its large size and same histopathological characteristics as conventional dermatofibroma. We repor...

Dermatofibroma is a very frequent lesion that usually appears as a slowly growing nodule in the dermis, and preferentially involves the lower extremities of women. Several clinical variants have been described. Giant dermatofibroma has been defined as a rare variant of dermatofibroma measuring more than 5 cm that presents typical histological features and a benign biological behavior. We report...

Dermatofibroma is a common benign fibrohistiocytic tumor with many clinicopathological variants. Myxoid dermatofibroma is one of these variants, which is characterized by marked stromal mucin deposition. This report presents a case of myxoid dermatofibroma on a great toe that had been slowly growing for two years. Histopathologically, the relatively well-circumscribed dermal tumor was separated...

Dermatofibroma is a slowly growing common benign cutaneous tumor characterized by hard papules and nodules. The rarely seen erosions and ulcerations may cause difficulties in the diagnosis. Dermatofibrosarcoma protuberans, which is clinically and histopathologically of malignant character, displays difficulties in the diagnosis since it has similarities with basal cell carcinoma, epidermoid car...

Dermatofibromas are a common finding in the daily clinical practice. Most lesions are found incidentally or because patients seek medical attention due to the aspect of the lesion. Rare variants of dermatofibroma such as aneurismatic or atrophic dermatofibroma can be encountered simultaneously; thus, these combined features may raise the possibility of other diagnoses to be considered. By provi...

Dermatofibroma is a common benign fibrohistiocytic lesion that usually appears as a slow-growing, firm dermal nodule with a predilection for the legs of middle-aged women. They are usually smaller than 2 cm in diameter. Many histological variants have been described. Generally, the clinical and histological diagnosis is straightforward, but differentiating it from other cutaneous tumors can be ...

Dermatofibroma is a benign fibrohistiocytic tumor, common and easily diagnosed when classical clinicopathologic features are present. The atrophic variant of dermatofibroma is of uncertain origin. This lesion is characterized clinically by a flat or atrophic and depressible surface. Histopathological features show reduction of the thickness of the dermis and elastic fibers. We report a typical ...
