The Atrophic Dermatofibroma: A Delled Dermatofibroma
The Journal of Dermatology, 1995AbstractAtrophic dermatofibroma has been proposed as a term to designate a new and specific type of dermatofibroma. We report the clinical and histopathological findings in two cases of atrophic dermatofibroma. The peculiar morphology of these lesions simply represents a conspicuous example of the frequently seen central depression in dermatofibroma ...

Histopathology, 1997
Aims:To describe a series of five granular cell dermatofibromas as an unusual and rare manifestation of fibrohistiocytic tissue response.Methods and results:Five granular cell dermatofibromas were collected out of 136 tumours filed as granular cell tumours. Clinically, all lesions occurred on the shoulder or back of middle‐aged adults (two women, three

DeRmpath Clinic: Dermatofibromas
European Journal of Dermatology, 2016Case 1A 38-year-old Caucasian male presented with a lesion on his left forearm which had been present for two years. It had become increasingly firm over time and was occasionally tender. Examination revealed a 5×5-mm blue/purple-coloured papule with a subcutaneous component palpable beyond the visible lesion.

Sclerotic Epithelioid Dermatofibroma
The American Journal of Dermatopathology, 2011Dermatofibroma ("fibrous histiocytoma") is a common soft tissue lesion with many variants based on a great variety of architectural patterns, cellular morphology and stromal reactions. The coexistence of 2 or more patterns within a single lesion is well known and causes diagnostic difficulties.

Collapsing Angiokeloidal Dermatofibroma
The American Journal of Dermatopathology, 2012A heterogeneous group of benign fibrohistiocytic lesions has been assembled under the umbrella term, dermatofibroma. These lesions share a morphology of bland spindled cells encompassed by and intercalating through thick dermal collagen; unique variants have been described based on secondary histologic features, some of which include aneurysmal, myxoid,

Dermatofibromas skin lesions seen in a dermatology practice. They are well circumscribed, solitary or multiple, usually hyperpigmented dermal nodules, typically less than 1 cm in diameter. They may be slightly protuberant, but are most often flat, and are generally located on the extremities.

Deep Penetrating Dermatofibroma
Dermatologic Surgery, 1998Deep penetrating dermatofibroma is an unusual and histologically distinctive form of dermatofibroma that usually occurs on the lower extremities of adults.The dermatologic surgeon and pathologist should be aware of this entity to prevent excessive treatment of a benign condition.We are reporting a case of deep penetrating dermatofibroma with the ...

Ultrastructure of dermatofibroma
Archiv f�r Dermatologische Forschung, 1973Eight dermatofibromas were studied by electron microscopy. The essential cell was the fibroblast, characterized by a well developed rough endoplasmic reticulum (RER), a distinct Golgi zone and large numbers of cytofilaments. The fibroblast of the dermatofibroma was engaged in collagen production and fat storage.

Multinodular Hemosiderotic Dermatofibroma
Dermatology, 1990We describe a patient who developed a pigmented plaque on the anterior aspect of his right knee clinically mimicking angiokeratoma circumscriptum or malignant melanoma. Histopathological examination demonstrated a multinodular hemosiderotic dermatofibroma in which the cellular tumor islands were separated by areas of hyalinized collagen. Multinucleated
